Oceanic squids reach the higher cephalopod biomass worldwide and their fishery represents about half of the total world cephalopod captures (FAO 2015). However, present knowledge of their embryonic and larval stages is very poor. The present 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 objective of the study is to know the growth, behaviour and morphologic adaptations to the environment of oceanic squid paralarvae under controlled conditions.
The family Ommastrephidae, the most important fishery resource of oceanic squid worldwide, has been selected to develop this study. The species selected are Illex coindetii, Todarodes sagittatus and Todaropsis eblanae, the main ommastrephid species fished in European waters. Also, the samples of ommastrephid paralarvae collected during recent oceanographic cruises in the Mediterranean Sea are analyzed in comparison with the cultured material.
The CALOCEAN project is developed at the Institut de Ciències del Mar (CSIC), Barcelona, Spain and the principal investigator is Roger Villanueva. The first CALOCEAN-1 project began in January 2010 and ended in December 2012. The research continued under the CALOCEAN-2 project that began in January 2013 and ended in December 2015. This research project is funded by the Ministerio de Economía y Competitividad of Spain research grants CALOCEAN-1 ("Estudio del desarrollo embrionario y larvario de calamares oceánicos de interés pesquero”, grant number AGL2009-11546) and CALOCEAN-2 (“Cultivo larvario de calamares oceánicos”, grant number AGL2012-39077).
