dc.description.abstractTo move forward in the farming ofOctopus vulgarisparalarvae, it is necessary to search for a live prey easy to obtain and maintain in the laboratory that meets the nutritional requirements of the octopus paralarvae and adapts to its predatory behaviour.Grapsus adscensioniszoeae (Crustacea, Decapoda) seems to fulfil most of these targets, and it was herein used to deepen knowledge of paralarvae lipid requirements and composition, growth and survival. To this purpose, the effects of feeding withGrapsuszoeae as sole prey were compared withArtemiaat two different stages (nauplii and juveniles), which also differed in their lipid profiles. After 15 days of feeding, the best growth and survival of paralarvae was obtained in theGrapsusgroup, and no differences were observed between bothArtemiagroups. Triacylglycerides storage in paralarvae seemed to be co-related with a lower growth and survival, but not with its prey levels. Contrarily, sterol ester levels were higher in paralarvae fedGrapsus, reflecting its content in the prey. The best paralarval viability was related to higher levels of 22:6n-3 (DHA) and 20:4n-6 (ARA), also reflecting its higher content in the prey. On the other hand, neither the 20:5n-3 (EPA) levels in the prey nor in paralarvae were related to growth or survival. The implications of these results are discussed considering the lipid requirements ofO. vulgarisparalarvae.
