Review of the current state of the culture of Sepia officinalis (Mollusca, Cephalopoda)

Nereis Review of the current state of che culture of Sepia officinalis (Mol1usca, Cephalopoda) Maria GregoriI and Carmen Hernández-Cruz 2 \Esrudianre de Ciencias del Mar en la Universidad de AJicanre. 2PTU, Deparramemo de Biología, Facultad de Ciencias del Mar.

[email protected], [email protected] AB5TRACT According ro rhe conclusions of rhe XCongreso aciona! de Acuicu!rura (2005), species diversificarion is one of rhe prioriries of world aquaculture. lhree marrers have been discussed in rhis review concerning rhe curreO[ srare and knowledge of rhe culture of Sepia ojficinaLis: feeding, culture densiry and reproducrion in capüviry. With respect ro the feeding of rhis species, mere is avariery of ex:perimenrs like me ones carried our by Forsythe et al., 1994, Fuenres et a.l, 2001, Domingues el aL., 2004, and 00mingues el al., 2005, in which rhese animals were ofrered difrercnr djers, and rheir growrh rares and survival were esrimatecl. The resulrs obtained poine our mar me feeding during rhe early srages of Jife muse consise of living preys, suggesting mae che culture of chis species is economically non-viable. Culeure densiry studies performed by Forsyrhe et al., 1994, Domingues etal., 2003 and Domingues et al., 2005 established the optjma! conditions for che culture and concluded rhat rhis species should be cuhured al low densiries, due ro individua! cannibalistic and aggressive behaviour of the males during reproductive season. Growrh of animais was Jower at higher densieies. Regarding reproduction, Rodríguez de la Rúa et al, 2005 highlight ehae rhe: reproductive cycle is characeerized by an inrermiuenr terminal spawn, and thae spawn only occurs once in che ¡ife rime of the animal afrer which they die making ir especially hard eo conceive rhe commercial culrure of Sepia officialis. 254 Communications: Aquacuúure, Seaculture and Fishing REFERENCES DOMINGUES, P.
