“…diversicolor were sampled in October 2017 from the intertidal of Leangbukta bay, Trondheim, Norway, and immediately taken to the laboratory for processing. Upon arrival, non-intact or inactive individuals were discarded; the remaining worms were placed in 200 ml plastic cups with 1 μm filtrated seawater (34 ppt salinity) and allowed to evacuate their gut for 2 h (Wang et al 2019). Thereafter, the polychaetes were weighed individually (SE 622; VWR) and randomly distributed among 20 groups comprised of 70 individuals each, and placed in experimental tanks.…”

“…In total, there were 5 treatments, each with 4 replicates. FF has previously been used as a high-quality feed (1 mm diameter; Ewos Start 040) (Wang et al 2019). SS was collected from a land-based salmon smolt freshwater RAS (Lerøy Belsvik).…”

“…The ash, total C and N contents, total lipid, FA and amino acid (AA) profiles of the polychaetes and experimental diets were analyzed as described in Wang et al (2019). In short, ash was determined by combusting samples at 450°C in a muffle furnace for 5 h. Total C and N were measured using an elemental analyzer.…”

“…Total lipids were extracted and determined gravimetrically using the method of Bligh & Dyer (1959). FAs were esterified to FA methyl esters using BF 3methanol (Metcalfe et al 1966) and analyzed by means of gas chromatography (Agilent Technologies 7890B) with helium as the carrier gas and a WCOT fused-silica capillary column coated with CP-wax 52CB (Holger CP7713) (Wang et al 2019).…”

“…H. diversicolor has been shown to grow well on aquaculture side streams (Pajand et al 2017, Marques et al 2018, Wang et al 2019, Yousefi-Garakouei et al 2019. By diverting some of the fish sludge used for biogasification to polychaete production, and combining this with solid biogas digestate (SBD) to serve as a feed source for the polychaete worms could add to the value of both wastes.…”

We evaluated the potential of the marine bristleworm Hediste diversicolor (Polychaeta) to recycle side streams from aquaculture and biogas production. Polychaetes were fed along a gradient from pure aquaculture sludge (SS) to pure solid biogas digestate (SBD) in 33% steps, with a positive control reared on fish feed (FF). Worms fed with FF showed the highest specific growth rate; there were no significant differences in growth rates among worms fed pure SS, pure SBD or their mixtures. While the diets differed significantly in protein concentrations, the worms showed comparable protein concentrations at the end of the 30 d rearing period (42−47% of dry weight). Lipid content in the worms was positively correlated with that in their diets. The worms on mixtures of SS and SBD with different ratios showed similar amino acid profiles. Fatty acid (FA) composition in the polychaetes reflected diet, where increased fractions of SBD resulted in an increase in long-chain polyunsaturated FAs, such as arachidonic (C20:4 n-6) and eicosapentaenoic (C20:5 n-3) acids, whereas increased ratios of SS increased docosapentaenoic (C22:5 n-3) and docosahexaenoic (C22:6 n-3) acids. These results suggest that polychaetes can recycle organic nutrients from aquaculture and biogas side streams into high-quality proteins and lipids, and can potentially serve as ingredients for aquafeeds.

Trophic upgrading of long-chain polyunsaturated fatty acids by polychaetes: a stable isotope approach using Alitta virens

et al. 2021

Polychaete worms are rich sources of polyunsaturated fatty acids (PUFA) and are increasingly incorporated into aquaculture broodstock diets. Conventionally, the build-up of PUFA in polychaetes was considered passive, with direct accumulation along the food web, originating with microalgae and other primary producers. However, it has been argued that polychaetes (and other multicellular eukaryotes) are capable of PUFA biosynthesis through the elongation and desaturation of precursor lipids. We further test this hypothesis in the ecologically and economically important nereid polychaete Alitta virens by adopting a stable isotope labelling approach. Worms were fed a 13C-1-palmitic acid (C16:0) enriched diet with the resulting isotopically enriched lipid products identified over a 7-day period. The data showed strong evidence of lipid elongation and desaturation, but with a high rate of PUFA turnover. A putative biosynthetic pathway is proposed, terminating with docosahexaenoic acid (DHA) via arachidonic (AA) and eicosapentaenoic acids (EPA) and involving a Δ8 desaturase.
