Oceanic squids reach the higher cephalopod biomass worldwide and their fishery represents 51% of the total world cephalopod captures (FAO 2010). However, present knowledge of their embryonic and larval stages is very poor.The CALOCEAN project aims to obtain the laboratory methods needed to study their embryonic and paralarval development under experimental conditions and known their morphology and behaviour as far as possible. Embryos and paralarvae are obtained in laboratory using wild collected mature squids, and in vitro fertilization techniques. The main challenge of this research project is the culture of oceanic squid paralarvae.
