“…The FA profiles displayed by the whole body of D. neapolitana revealed that the most dominant FA was 16:0, followed by the PUFA 20:5n-3. In general, this trend was similar to that found for other polychaetes by Fernandes et al [50] for Hediste diversicolor and by Jerónimo et al [51] for H. diversicolor, D. neapolitana, Sabella cf. pavonina, and Terebella lapidaria, all collected in the same location in Ria de Aveiro.…”

“…The use of FA profiles of soft tissues and EF of mineral structures in marine species has been optimized to put forward faster and more accurate methods of analysis that can also reduce potential environmental impacts (associated with the residues they generate) that allow to best discriminate the geographic origin of these organisms, namely those that feature an important commercial value [23,28,[44][45][46][47][48][49][50]. Most of the available studies to date using these methods, either when they are applied individually or combining more than one approach (e.g., FA profiles and stable isotopes [34], elemental fingerprints and stable isotopes [36]), are mostly focused on food safety issues rather than the implementation of effective management plans for endogenous marine resources that may be vulnerable to poaching.…”

“…The FA belonging to the SFA and PUFA classes were responsible for most of the differences recorded among locations (p < 0.05; Table S1 on Supplementary Data). These dissimilarities in FA profiles of polychaetes among locations were likely associated with a differential physiological response to changes in environmental conditions (e.g., salinity and temperature) that shape the environment in their sampling locations [22,50,55,56]. At higher temperatures, the reorganization of the membrane structure is needed to maintain membrane fluidity and homeostasis, leading to an increase in FA saturation or the prevalence of shorter-chain FA [57].…”

Diopatra neapolitana Delle Chiaje, 1841 (Annelida, Onuphidae) is one of the most exploited polychaete species in European waters, particularly in Ria de Aveiro, a coastal lagoon in mainland Portugal, where the overexploitation of this resource has led to a generalized decline of local populations. In an attempt to reduce the impact of harvesting, several management actions were implemented, but illegal poaching still fuels a parallel economy that threatens the sustainable use of this marine resource. The present study evaluated the combination of fatty acid profiles and elemental fingerprints of the whole body and jaws, respectively, of D. neapolitana collected from four harvesting locations within Ria de Aveiro in order to determine if their geographic origin could be correctly assigned post-harvesting. Results showed that both fatty acid profiles and elemental fingerprints differ significantly among locations, discriminating the geographic origin with higher accuracy when combining these two natural barcodes than when employing each individually. The present work can, therefore, contribute to the implementation of an effective management plan for the sustainable use of this marine resource, making it possible to detect if D. neapolitana was sourced from no-take zones and if it was collected from the place of origin claimed by live bait traders.

The rapid growth of aquaculture has prompted the exploration of alternative and sustainable feed ingredients. Polychaetes, such as Hediste diversicolor, offer promise in the circular economy due to their ability to recycle waste materials from bioindustries and convert low nutritional value fatty acids (FA) into eicosapentaenoic (EPA) and arachidonic (ARA) acids. This study explored the combined effect of temperature and salinity on growth and LC-PUFA biosynthesis in H. diversicolor fed on a side stream diet (33% sludge from salmon aquaculture (AS) and 66% solid-phase digestate from biogas production (SBD)). Polychaetes were cultured for 28 days along a 5-step temperature and salinity gradient ranging from 7.7 to 17.9 °C and 5 to 40 psu, respectively. Growth was highest at high temperatures (≥ 14.3 °C) and salinities (≥ 35 psu). The FA composition remained relatively stable across different culture temperatures, while salinity exhibited higher levels of n − 3 PUFA and n − 3 LC-PUFA at lower salinities (5 and 15 psu) compared to higher salinity (35 psu), mainly driven by EPA. This suggests that salinity may exert a more pronounced effect than temperature on the FA profiles of H. diversicolor. Despite low temperature and high salinity (40 psu) significantly upregulating the expression of elongase and desaturase genes, this was not translated into higher LC-PUFA. Remarkably, polychaetes exhibited high levels of n − 3 and n − 6 LC-PUFA, even when fed a diet deficient in such FA. These findings highlight the potential of H. diversicolor for LC-PUFA biosynthesis, positioning this species as a promising candidate for producing high-nutritional-value ingredients for aquafeeds.
