Octopus vulgaris farming at large scale can only be attained using live prey during the paralarvae stage. Presently, only Artemia complies with this requirement. Nevertheless, its sole use delivers poor paralarvae growth and survival. Some species of marine zooplankton are better prey for marine fish larvae compared to Artemia, since its composition is richer in several important nutritional components. Among these are phospholipids and specific fatty acids, namely docosahexaenoic acid, eicosapentaenoic acid and arachidonic acid. During the present experiment, octopus paralarvae were fed a co-feeding scheme of spider crab (Maja brachydactyla) zoeae and Artemia (1:2, Artemia/Crab zoeae). The use of spider crab zoeae was justified by their availability in commercial facilities, where adult spider crabs are maintained to be sold to the public. There, fecund and spawning females are present in large numbers, and zoeae availability is often high and implies no production or zoeae collection ...
