The interest in understanding the capacity of aquatic invertebrates to biosynthesise omega-3 (ω3) long-chain (≥C20) polyunsaturated fatty acids (LC-PUFA) has increased in recent years. Using the common octopus Octopus vulgaris as a model species,

To elucidate the in vivo endogenous ability of pikeperch (Sander lucioperca) larvae to deacylate and reacylate phospholipids and to elongate and desaturate PUFAs, 20 days post hatch (DPH) fish were incubated with either [1-14C]20:4n-6 bound to PC and
