<p>Fatty acid profiles of <i>Hediste diversicolor</i> polychaetes fed commercial feed (C) and beluga sturgeon (<i>Huso huso</i>) by-product feed (W) at four stocking densities over a 60-day culture period. Lowercase letters indicate significant differences among stocking densities within the commercial feed groups (C1–C4), and uppercase letters indicate significant differences among stocking densities within the waste feed groups (W1–W4), as determined by one-way ANOVA followed by Duncan’s multiple range test (P < 0.05). Asterisks (*) indicate significant differences between diets at the same stocking density based on independent-samples t-tests (P < 0.05).</p>
