Researchers from the oceanographic centers of Vigo and Tenerife of the Spanish Institute of Oceanography (IEO) have managed to reproduce octopuses in captivity after 20 years of research on the larval culture of common octopus (Octopus vulgaris).
This fact is an international scientific milestone for the IEO, contributing to the commercial exploitation of this species so demanded by the markets currently.
Therefore, the Spanish Institute of Oceanography – an agency attached to the Ministry of Science, Innovation and Universities – has achieved one more achievement through the use of new cultivation and feeding techniques consistent with the growth of larvae with a more profitable and replicable methodology than those used so far. As for the fattening of juveniles to adults, it has been carried out for years with specimens caught in the sea.
The common octopus has a short life cycle but with growth potential, which makes it an ideal species for its cultivation and development in captivity.
Currently, it is a highly demanded product in national and international markets and with a lot of commercial interest, which has led to an increase in its fishing and an increase in studies and scientific research to domesticate this and other species of this cephalopod. In addition, it is a species of great commercial interest in Spain and the Mediterranean and its demand is increasing in other countries such as the United States.
This fact, together with its high price in the market, makes it an excellent candidate for the diversification of aquaculture. The octopuses go through different stages in their development: eggs, paralarvae, juveniles and adults. The tests carried out in the IEO, based on this patent, improve the results obtained until now in the larval culture and have managed to obtain juveniles with which to start the fattening phase until reaching adults.
Recently the IEO and NUEVA PESCANOVA have signed a contract whereby this company has a preferential option to license the IEO Patent on these investigations.
Both institutions have an interest in closing the commercial captive cycle of common octopus.
This advance manages to overcome what until now was considered as the main stumbling block for the commercial cultivation of this species, also applying a methodology that is more profitable and replicable than those developed so far. Therefore, current efforts are focused on obtaining juveniles and studying their economic viability.
