“…According to Mandario et al [6], polychaetes can be cultured using muddy wastes from other culture species, even with the biofoc sediments discharged from shrimp or salmon ponds. Te efciency of A. pusilla has been highlighted by Gómez et al [9,13] as a candidate for nutrient recycling from marine aquaculture sludge.…”

“…In nature, deposit-feeding polychaetes play an essential role in degrading mudfats, so a controlled culture is needed to produce sufcient biomass and avoid harvesting from natural populations. Furthermore, due to their biochemical composition and detritivorous capabilities, they have been used as bait [7,8], for sludge treatment of marine recirculation systems [6,9], as feed for Panulirus ornatus juveniles [10], and as an ovarian maturation stimulant for shrimp [11,12]. According to Gómez et al [13], A. pusilla is an efcient remediating species for reducing organic waste in RAS aquaculture sludge with a density of 200 organisms m −2 , representing a conversion efciency of 4.22 g of total organic matter per g A. pusilla.…”

This study aims to provide a quantitative analysis of the amino acids (AAs) and fatty acids (FAs) found in by-products of the Patagonian marine polychaete Abarenicola pusilla. Samples of polychaetes were taken in different seasons and processed to generate three by-products: eviscerated whole body, press cake, and press liquid. The results showed a clear seasonal difference, with essential nutrients decreasing significantly in winter. For example, from eviscerated whole body specimens, essential fatty acids, eicosapentaenoic acid (EPA), and arachidonic acid (ARA) maintained a relationship of 1 in summer, 1.24 in winter, and 1.5 in spring and autumn. In comparison, docosahexaenoic acid (DHA) was undetected in some extracts in winter. However, the fatty acid content in press liquid resulted in high variation, with the lowest content during the autumn. In contrast, the press liquid and press cake responded similarly. DHA decreased from spring to winter (from 0.1 to 0.08), whereas EPA resulted in high variation along the seasons (from 0.57 to 0.03) from summer to autumn. The highest protein values were observed in the spring and summer. In contrast, lipid values remained under 10% constant throughout all seasons, unless in the eviscerated carcass, where 5 to 3% higher lipids were found, indicating that A. pusilla uses protein more efficiently than lipids as an energy source. The most abundant EAAs were lysine (LYS) and leucine (LEU), while glycine (GLY), glutamic acid (GLU), and alanine (ALA) were the most abundant NEAAs. Finally, A. pusilla harvest conditions and the type of extract recommended to produce a valuable ingredient for marine aquafeeds are discussed.

“…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 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 (2018Gómez et al ( , 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.…”

Interest in using polychaeta annelids as an alternative feed source for aquaculture was generated by providing an alternative to clams and mussels as bait. This has subsequently led to increased interest in their reproduction, with countries such as the United Kingdom, China, Japan, Australia and France successfully creating extensive, semi-intensive, and intensive systems of production. Studies have also reported the use of polychaeta annelids in Integrated Multi-trophic Systems (IMTA), their interest as ornamental species, and research at the biotechnological level. In Latin America, Ecuador, Chile and Peru report research on their exploration in culture, their use as shrimp feed and their involvement in IMTA. However, so far, Chile is the only country that has successfully achieved knowledge of the reproductive cycle of two polychaeta species. The polychaeta families that demand greater research include Eunicidae, Onuphidae, Nereididae, Arenicolidae, and Glyceridae. Due to their ecological characteristics, some species are also potential contributors to parasite infections. As such, correct taxonomic identification based on their ecological and physiological characteristics, could increase the potential for their use as an alternative aquaculture feed ingredient, reducing feeding costs through recirculation systems. The present investigation was conducted through research using the bibliographic databases: Elsevier, Science Direct, Scielo, Scopus and Google Scholar.

“…Incorporating polychaetes in bioremediation processes can potentially recycle proteins and polyunsaturated fatty acids present in aquaculture sludge. Several studies showed that certain species of polychaetes, such as Perinereis nuntia vallata, Abarenicola pusilla, and Hediste diversicolor can assimilate nitrogen, organic carbon, and increase their lipid content when fed with specific types of aquaculture sludge [21,[28][29][30][31][32][33]. These appreciated components can be incorporated into aquaculture feeds, thus reducing dependence on scarcer traditional ingredients such as fishmeal and fish oil.…”

The potential of polychaetes for the bioremediation of aquaculture sludge gained more attention in recent years. These organisms can reduce organic matter and nutrients contained in the sludge of several aquaculture species, improving the sustainability of these activities. The aim of this study was to evaluate the removal performance of Perinereis gualpensis (Jeldes, 1963) being fed with aquaculture sludge produced by a recirculating system cultivating Atlantic salmon. The experiment involved adding different amounts of sludge (10% and 20% with respect to total substrate) at a density of 300 organisms m−2 during 30 days. A treatment without sludge served as a control, using natural substrate. The highest removal rate of total organic matter (TOM) (23.95 ± 13.19 g m−2 day−1) was achieved by P. gualpensis with 20% sludge addition, a reduction of about 36% compared to the total amount added at the beginning of the trials. The organisms fed with aquaculture sludge presented higher nitrogen (8–9%) and carbon (40–43%) contents, with a maximum organic carbon assimilation of 32% in relation to the total content in the sludge. The high survival (88–95%) and positive growth rates (0.28% day−1) achieved by P. gualpensis indicated that this species can be sustained with salmon sludge as the only source of food. These results indicate that P. gualpensis is a promising candidate for removing nutrients from salmon effluents. Moreover, the protein contents achieved by the organisms (52–58%) meet the dietary protein requirements of several aquaculture species. Further research is needed to determine the maximum bioremediation capacity of this species and to evaluate the lipid content and fatty acid profiles of P. gualpensis to determine its potential application in aquaculture feed.
