For the research of this article, a bibliographic search was performed in different databases (Elsevier, Science Direct, Scielo, Web of Science, Scopus and Google Scholar), with the keywords in English and Spanish: “polychaete”, “aquaculture with polychaete”, “Recirculating systems with polychaete (a)”, “sewage treatment and polychaetes”, “bait worms”, “bait polychaeta”, “bait polychaeta for recreational fishing”, “aquaculture with polychaetes” and “los poliquetos en la acuicultura”.
Ornamental Polychaete Annelids
Some coral species of “polychaetes” from the Sabellidae and Serpulidae families are commonly known as "marine flowers" and are commercialized in the ornamental market (Olivotto et al. 2011; Jäger 2011, 2012; Murray et al. 2012, 2013; Palmtag 2017; Carvalho et al. 2019; Capa et al. 2021). This is because their anterior region, called the gill crown, exhibits a variety of colors, and their large size makes them very attractive to consumers (Tovar-Hernández 2009; Olivotto et al. 2011; Dávila-Jiménez et al. 2017). The genera of the Sabellidae family include: Sabellastarte with species like : S. japonica; S. magnifica, S. sanctijosephi, S. spectabilis, S. fallax, and S. samoensis (Bybee et al. 2006; Bybee et al. 2007; Murray et al. 2012; Bybee and Murray 2017) and S spp. (Costa et al. 2016); the genus Bispira (Tovar-Hernández and Pineda-Vera 2008; Bastidas-Zavala 2009; Bastidas-Zavala and Sánchez-Ovando 2021; Capa et al. 2021) includes Bispira brunnea (Capa et al. 2021); the genera Anamobaea, Notaulax (Capa et al. 2021) and Branchiomma, with the species Branchiomma luctuosum (Carvalho et al. 2019); as well as the genus Sabella with species like Sabella spallanzanii and Sabella pavonina (Capa et al. 2021). In the Serpulidae family, genera include Spirobranchus, Protula and Serpula (Bastidas-Zavala 2009; Bastidas-Zavala and Sánchez-Ovando 2021; Capa et al. 2021). Unfortunately, though, this valuation in the market, means that there are often destructive practices used to obtain these polychaete annelids, a similar situation to what is seen in sport fishing (Bybee et al. 2006; Dávila-Jiménez et al. 2017). Hence, aquaculture can be considered as an alternative way to conserve and commercialize these species without destroying them.
Sport fishing
The trend of using “polychaetes” rather than clams and mussels as bait in sport fishing began sometime between 1921 and 1922 in the United States (Long Island, N.Y.), (Creaser et al. 1983). This thus expanded its catchment area to the coast of North America, East Asia and Borthern Europe (Gambi et al. 1994).
Since 1980, there has been an interest in the lucrative production of these “polychaetes”, thus increasing its economic value (Sá et al. 2017; Cabral et al. 2019) and demand as bait for fishing (Garcês and Pereira 2011; Sá et al. 2017; Pombo et al. 2018; Mandario 2020; Martin et al. 2020; Broquard et al. 2022; Escobar-Ortega et al. 2022). It also became directly used by the crustacean and fish aquaculture industries (Olive and Cowin 1994; Olive 1994; Fidalgo and Costa 1999; Olive 1999; Messina et al. 2005; Fidalgo and Costa et al. 2006; Brown et al. 2011; Garcês and Pereira 2011; Hamdy et al. 2014; Mohammad 2015; Pombo et al. 2018; Martin et al. 2020), as is the case of the company, Seabait Ltd in the UK United. As a result, Seabait Ltd. became a sector leader in the production and sale of Alitta virens (N. virens), and was later taken over by the company Topsy Baits (Netherlands). This also sparked other countries’ interest in the research and production of “polychaetes”, such as Australia, China and Korea (Nesto et al. 2012).
In Australia, 1996, the company Aquabait was established in Dora Creek (New South Wales), and began production of Diopatra aciculate. Meanwhile, in China, the company Qidong King Power Polychaete Aquaculture Co., Ltd., became focused on the production of Alitta virens (N. virens) (Nesto et al. 2012). Font and Lloret (2011), reported that between 2007 and 2009, the polychaetes Perinereis aibuhitensis "Korean worm", Marphysa sanguinea "threadworm", Glycera dibranchiata "American worm" and Arenicola spp. "sandworm”, accounted for 43.2% of the total invertebrates used as bait, Globally, there are roughly 60 species of polychaetes, belonging to 12 families (Cole et al. 2018; Pamungkas et al. 2019), being used as bait (Cole et al. 2018; Pamungkas et al. 2019; Kannapan et al. 2021). However, this number varies between studies, with Pombo et al. (2020), and Yang et al. (2022), reporting the use of 27 species.
Cunha et al. (2005) and Barrington et al. (2009), reported that in 1999, the worm market in Europe reached a valuation of around € 200 million, but the exact value is not known, as it is the “black market”, and there is a lack of sales reporting. Likewise, Whatson et al. (2017), De Cubber et al. (2018), Mandario (2018), Cabral et al. (2019), and Mandario (2020) estimated that the annual harvest of polychaetes used for bait, was 121,000 tons worth USD 9.15 billion in 2016. However, the same authors note that FAO reported 314 tons of marine worms caught in 2015 (not all countries are included in the study), which suggests the same problematic, under-reporting of sales. In the United States, Maine reported that sales of Glycera dibranchiata and Alitta virens (Nereis virens) reached USD 8.7 million in 2020 (Maine.gov).
Despite not having an updated record of the volume of commercialization of “polychaetes” as live bait, due to its dependence on the species and country, some authors have reported the price of some species (Table 1). Currently, the estimated percentage of bait that “polychaetes” make up is 19.5% in Australia, 4.7% in North America, 1.6% in Europe and Africa, and less than 0.3% in Asia (Cole et al. 2018). The following table organizes the bibliographic information regarding the families and species of “polychaetes” harvested from their environment for recreational or aquaculture purposes, as well as their locality of provenance, and in some cases their commercial value, with the source of information also identified (Table 1).

Aquaculture
History
The first commercial cultivation of “polychaetes” began in 1984 (Olive 1999). Intensive commercial aquaculture of “polychaetes” has also been successfully carried out in countries like the United Kingdom by the company Dragon Bait, England by the company Seabait Ltd, and Holland and Ireland by the company Topsy Bait with the cultivation of Alitta virens (Nereis virens), also known as "ragworm". This has also occurred in Australia by the company Aquabait Ltd, which is dedicated to the cultivation of the "tube worm", Americonuphis reesei. In France, this has been achieved by the company Hemarina S.A. with the species Arenicola marina (Herrsera-Perez 2020) and Lumbrinereis impatiens. In Spain, the production of Hediste diversicolor (Nereis diversicolor, scientific name not accepted) and Arenicola marina is reported (García del Real 2007). Other examples of cultivation include the species Neanthes japonica in Japan; Perinereis brevicirrus in Taiwan; and the cultivation of Glycera dibranchiata and Alitta virens (Nereis virens) by Maine in the United States (Olive and Cowin 1994; Grupo de Ecología, Universidad de Cantabria y TEICAN Medioambiental S.L 2002).
Since then, “polychaete” aquaculture has shown sustained growth, thanks to the collaboration of industry, which has helped fund research on reproductive biology and the growth of polychaete annelids to meet the demands of aquaculture, sport fishing and the ornamental market (Murray et al. 2012; Palmer et al. 2016; Cole et al. 2018). Currently, its commercialization is evident in different forms, such as being sold live, frozen (Yang et al. 2022) dried, flaked, canned, or in the feed formula of species of commercial interest, like in shrimp brood stock as reported by Nascimento et al. (1991) and Mandario et al. (2018). This trade is considered a profitable business, and has one of the highest costs in the international market (Table 1).
“Polychaetes” as Food in Aquaculture
“Polychaetes” are the highly preferred prey of fish and shrimp in benthic communities of natural ecosystems (Böggemann 2009; Choi 2016; Younsi et al. 2010; Priscilla et al. 2022). As such, it can be and is used as a feed resource in aquaculture production systems (Dinis 1986; Fidalgo e Costa et al. 2000; Stabili et al. 2013; Broquard et al. 2022). They have high nutritional content, as they are rich in fatty acids (FA), especially polyunsaturated fatty acids (PUFAS) and essential FA, better known as highly unsaturated fatty acids (HUFAS) which make them a valuable feed ingredient for fish and crustaceans (Pairohakul et al. 2021; Olive 1999; Brown et al. 2011; Stabili et al. 2013; Moussa et al. 2015; Pajand et al. 2017; Sahu et al. 2017; Mandario 2020; Jerónimo et al. 2021b; Kannappan et al. 2021), especially when some of these HUFAS include arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) (Poltana et al. 2007; Pombo et al. 2018; Chimsung et al. 2014; Palmer et al., 2014; Kannappan et al. 2021). “Polychaetes” also have an adequate ratio of n3:n6 FA (Moussa et al. 2015), which makes them very important for shrimp, as they have a limited capacity to synthesize FA (Mussucci 2013). These essential FA favor the development and maturation of gonads (Fidalgo et al. 2003; Fidalgo e Costa et al. 2006; Kumar et al. 2017; Palmer et al. 2014; Mandario et al. 2020; Kannappan et al. 2021), help induce spawning in several fish and crustacean species (Parandavar et al. 2015; Muli et al. 2016; Wang et al. 2019a; Mandario 2020; Kannappan et al. 2021; Yang et al. 2022), interfering with fertilization, hatching rates, egg production, egg viability, larval survival, and spawning frequency in shrimp brood stock (Pajand et al. 2016; Jerónimo et al. 2021b). They also affect P. vannamei (L. vannamei), P. kerathurus, Penaeus monodon, Cryphiops caementarius and fish in the families of Sparidae: Pagellus bogaraveo "bream" (Moussa et al. 2015); and Soleidae: Solea senegalensis "senegal sole", S. vulgaris "sand sole", and Solea solea "common sole" (Fidalgo e Costa 1999; Meunpol et al. 2005; Safarik et al. 2006; Cardinaletti et al. 2009; Leelatanawit et al. 2014; Moussa et al. 2015; Panakorn 2015; Mandario 2020;Yang et al. 2022; Zavala-Zavaleta et al. 2022).
“Polychaetes” are also an important source of protein, amino acids and vitamins (Muli et al. 2016; Murugesan et al. 2011a; Stabili et al. 2013) and are a good source of reproductive hormones, similar to those found in shrimp (Mandario 2020; Kannappan et al. 2021). Chimsung et al. (2014), found that the reproductive hormones found in “polychaetes”, progesterone (P4) and 17α-hydroxyprogesterone, are responsible for the induction of oocyte development in shrimp. In addition, Meupol et al. (2010) report that prostaglandin E2 (PGE2) extraction in “polychaetes” has positive effects on oocyte maturation, specifically during late maturation and the ovulation period.
“Polychaetes” are marketed as live, frozen or dried feed (Bloodwormdepot 2022; Seaanglingireland 2022; Hookersbaits 2022; Baitsrus 2022; Valfishing 2022; Topsybaits 2022; Proaqua 2023).
Integrated Multi-Trophic Aquaculture (IMTA)
Before the development of Integrated Multitrophic Aquaculture, “polychaetes” were already used in polyculture systems. Ryther et al. (1975) exposed two detritivores feeding “polychaetes”, Nereis virens and Capitella capitata, with wastewater in a shellfish culture alongside other hydrobiological resources, resulting in an effluent free of inorganic nitrogen and bacterial growth which contributes to eutrophication. The growth of the aquaculture industry has subsequently led to integrated multi-trophic aquaculture (IMTA) as a way to increase sustainability by looking for different mechanisms to remediate and take advantage of all its production (Tsutsumi et al. 1991; Tomassetti et al. 2015; Martinez-Garcia et al. 2019; Wang 2019b; Galasso et al. 2020; Giangrande et al. 2020; Giangrade et al. 2021).
These systems are characterized by the integration of species from different trophic levels, involving a main production with species like fish, and a secondary production using crustaceans, bivalves and algae. The aim of these systems is to use all the resources produced economically, and in turn, control the organic (food waste, feces, bacterial biomass and plant material) and inorganic matter generated from the production of the main species and the system (Granada et al. 2015; Stabili et al. 2019; Wang et al. 2019b; Galasso et al. 2020; Jerónimo et al. 2021a). Due to their suspensivorous, deposivorous and detritivores feeding, as well as the nutritional content of some “polychaetes”, they have been considered for use in IMTA systems. This is demonstrated in the research by Giangrande et al. (2005), Stabili et al. (2013), and Stabili et al. (2019), who used S. spallanzanii as a biofilter in the remediation of wastewater from aquaculture, thus removing different groups of bacteria including potentially pathogenic bacteria for humans such as vibrios (Stabili et al. 2010). Likewise, Licciano et al. (2005) found that S. spallanzanii has high bacterial removal efficiency of Vibrio alginolyticus, and this was later confirmed by Blake and Giangrande (2011), Olivotto (2011) and Naspirán-Jojoa et al. (2022). Tsutsumi et al. (2002) also found that Capitella sp. 1 was an efficient bio-remediator of organically enriched sediments. Similarly, Kang et al. (2013), exposed the “Polychaete” Perinereis aibuhitensis to the toxicant endosulfan, a contaminant from aquaculture, concluding that it can effectively break down the toxicant in contaminated aquatic sediments. Gómez et al. (2018, 2019), reported that Abarenicola pusilla has the potential to reduce organic matter of wastewater from marine recirculating systems. Furthermore, Wang et al. (2019a, b), evaluated the potential of the “polychaete” Hediste diversicolor for the recycling of wastewater from aquaculture, concluding that the high-quality increase of protein and lipids make it a potential ingredient for aquaculture feed. This conclusion was shared by Jerónimo et al. (2021b) with the “polychaetes” H. diversicolor, Terebella lapidaria, Diopatra neapolitana and Sabella pavonina that showed high levels of polyunsaturated fatty acids, and demonstrating that it is possible to produce a biomass of polychaetes with high nutritional content in an integrated multi-trophic system. Other species include Capitella sp., Nereis virens (Brown et al. 2011), Perinereis nuntia and Arenicola loveni loveni (Gómez et al. 2018), Marphysa sp. (Mandario et al. 2019), and Arenicola marina (Jerónimo et al. 2021a). Species of the genera Nereis, Arenicola, Glycera and Sabella can also be used for temperate systems (Barrington et al. 2009); while the species Alitta virens (Nereis virens) can be used for tropical systems (Chopin et al. 2012). Hence, the integration of “polychaetes” within an integrated multi-trophic system, requires knowledge of the biological and physiological characteristics of the species of interest. In addition, a suitable taxonomic identification is needed, as- some species identified in the research have not been reported in their place of origin.

Ornamental Aquaculture
Additionally, it was demonstrated by Murugesan et al. (2011b) that the "clownfish", Amphiprion sebae’s consumption of “polychaetes” improves its physical appearance, resulting in an intensified color, as well as a greater weight and size, when compared to the consumption of fish feed (formula containing fish remains) and clam consumption. This skin pigmentation is a fundamental feature influencing the economic market and its production in aquaculture (Velasco-Santamaría and Corredor-Santamaria 2011). In addition, Hossen et al. (2014) identified that the polyunsaturated fatty acid (PUFA) content, an important component in gonadal maturation and spawning, is high in “polychaetes” with the "striped gourami" fish Colisa fasciatus achieving high quality larvae with the consumption of “polychaetes” (Sales and Janssens et al. 2003). Likewise, Khiabani et al. (2019), report that the combination of lipids and fatty acids are determinants for the reproductive success and survival of the offspring of ornamental fish, with fertility rate, egg production, gonad development and fecundity being important factors in the mass production of young fish and their final selection. Although the requirement of lipids and fatty acids will depend on the ornamental fish origin (freshwater or marine), both groups need long chain fatty acids and a high degree of unsaturation (Sales and Janssens et al. 2003) which can be provided by “polychaetes”. Furthermore, the different colors of “polychaetes” can provide ornamental fish with carotenoids, favoring color intensity (Sales and Janssens et al. 2003).
Parasites
Due to the characteristics of their habitat and ecological niche, as well as their abundance and location in the marine food web, “polychaetes” have the potential to contribute to the transmission of parasites, as they are the preferred food of species produced in aquaculture, like shrimp and fish (Huston et al. 2017). This was demonstrated by Desrina et al. (2020), which found Enterocytozoon hepatopenaei (Fungus, Microsporidia) in the polychaetes Dendronereis spp., Marphysa spp. and Nereis sp. from a shrimp aquaculture farm on the north coast of Java Island (Indonesia). Furthermore, they reported that this parasite was found in Penaeus monodon (Thailand) and Penaeus vannamei (Vietnam, Thailand and India). Likewise, the same authors Desrina et al. (2013) and Haryadi et al. (2015) found that the "white spot virus" (WSSV) is a host of the “polychaete” Dendronereis spp., as it is a favorite food of the mentioned shrimp. “Polychaetes” are also involved in the life cycle of myxozoans and aporocotylid blood flukes (Digenea), which use “polychaetes” during the production of their larvae, thus infecting fish with cercariae and actinospores of myxozoans, which are the most abundant in their habitat (Huston et al. 2017).
Impacts
Countries that harvest these species without any management plans, result in overexploitation and modification of the biotic and abiotic characteristics of their habitat and environment (Fidalgo e Costa et al. 2000, Çinar 2013, Carvalho et al. 2013, Godet et al. 2014, Kannappan 2021, Broquard et al. 2022), such as with the release and exposure of ammonium and phosphorus compounds that favor eutrophication (Watson et al. 2017) or the introduction of foreign invasive species (Blake and Giangrande 2011) that compete with native species. Çinar (2013), reported that the increase in these populations is responsible for the re-structuring of the food web, introducing new infectious agents or parasites, which modify the habitat structure and gene pool. This also results in economic losses. As a result, countries such as the United States, United Kingdom, Australia and Portugal, implemented regulatory measures for their harvest (De Cubber et al. 2018), such as requiring licenses for the use of recreational and professional fishing. Meanwhile, in northern France, a law was introduced to restrict the number of individuals harvested to 100, and the total closure of some Arenicola spp. harvest areas were ordered (De Cubber et al. 2018).
Other potential uses
Other potential uses of “polychaetes” include being a food attractant in the diet of pets and fish with partially cartilaginous skeletons, due to the high concentration of glycosaminoglycans (GAGs), as reported by Stabili et al. (2013) with Sabella spallanzanii.
Wang et al. (2019b) also reported that Hediste diversicolor could be a potential species for biogas production, due to its nutritional characteristics.
Meanwhile, Capa et al. (2021) suggest that “sabellids” can be used as models in biological regeneration, specifically for basic and functional development in regenerative ecology with polychaetes like Myxicola infundibulum; or Hydroides elegans for embryological research, larval ecology or studies in biofouling, as well as the species H. ezoensis and H. dianthus for larval ecology studies. Spirobranchus lamarcki can also be used as a model in molecular and embryological studies, and both H. elegans and S. triqueter can be used as models in ocean acidification and biomineralization.
The polychaete annelids Neanthes japonica and Perinereis nuntia (Perinereis nuntia var. Vallata) are potential species for the bioremediation of domestic wastewater (Kurihara, Y 1983).
Likewise, numerous studies suggest that “polychaetes” have medical applications for human health (Kuijk and van Die 2010; Singh et al. 2014; Coutinho et al. 2017; Herrera-Perez 2020, García-Garza et al. 2021; Broquard et al. 2022). For example, different biopharmaceutical products can be obtained from Arenicola marina hemolymph such as HEMO2life, which can be used for transplant organ preservation; HEMOXYCarrier, which can be used as a universal oxygen carrier with potential use in blood transfusions, and HEMHealing, which can be used as dressing for chronic wound healing (Hemarina 2023).
Finally, research with Polychaete annelids is not only restricted to feed species of commercial interest in the reproductive stage. According to the Ecology Group, University of Cantabria, TEICAN Medioambiental S.L. (2002), Kolkovski et al. (1997) and Kolkovski (2000) report that polychaete annelids have been considered as a food source for fish larvae. It should be noted that within the life cycle of polychaete annelids, larvae can be a food alternative to artemia, copedecids and rotifers for fish and/or shrimp larvae, and this is an area that requires further study. Thus, the knowledge of polychaete annelids requires different areas of research and application.
Present and future in Latin America
Currently, Latin American countries are becoming increasingly interested in the production of polychaete annelids for the shrimp industry, with Naranjo and Tobías (2019) in Ecuador exploring species with aquaculture potential and concluding that the species Perinereis sp. is most optimal for reproduction and production in captivity. Likewise, in Chile, they have successfully reproduced “polychaete” species of the Nereididade family, including Perinereis gualpensis, Perinereis vallata, and of the Arenicolidae family, including Abarenicola pusilla. The collaboration of the company MARINAZUL S. A, and Ricardo Palma University in the project: "Technical Assistance and Training for the development of the Cultivation and Use of Nereis and Perinereis “polychaetes” as live and/or pelletized food in the aquaculture production of the company MARINAZUL S. A" as indicated in the subproject code PNIPA-ACU-SEREX-PP-000143, has enabled the transfer of knowledge and technology to neighboring countries like Peru, where the present author was part of the technical team on behalf of the University. However, regrettably, the company prioritized its own qualifications, and truncated lines of research at the biological and biotechnological levels.
In Mexico, Nuria Méndez (2016) and Dávila-Jiménez (2017) bred Capitella and Bispira brunnea at the laboratory level for research purposes, respectively. Their goal was to develop local “polychaete” worm culture technologies to meet the demand in shrimp and fish aquaculture, as well as ornamental aquaculture and sport fishing through technology transfer of research results to the productive sector. To this end, it is important that companies commit themselves to collaborate in an integral manner with research projects. Otherwise, it will result in research setback that would not be beneficial for the sector. In an initial phase, the aquaculture potential of local “polychaetes” of every Latin American country should be evaluated, and used as an alternative to live, frozen or dehydrated feed and food supplements. It is important to first determine their biochemical composition (carbohydrates, protein, lipids, fatty acids, amino acids and biomass), safety (detection of pathogens) and culture viability (ease of sampling of brood stock, maintenance in captivity, reproduction and obtaining viable larvae) before continuing onto the next stage. The second stage will involve the design and development of a method for production of pilot cultures of “polychaetes” which will be used to determine the optimal diets that will help increase the efficiency of shrimp and fish production. The third and final stage will be to determine the distribution presentation as food in order to conserve its properties. It is expected that the production and cultivation of “polychaetes” as an alternative feed for aquaculture will be more relevant in Latin American countries to reduce feed costs and be an additional and competitive alternative to those found in the market. It will also serve to open up different areas of research for the benefit of society.
