Spawning and early development of Loligo vulgaris Lamarck, 1798, under experimental conditions

Because of its characteristics and high market price, efforts are being made to introduce the European squid Loligo vulgaris into aquaculture. The results of previous trials to rear different stages of the squid did not satisfy the needs of commercial culture. In this study, three live females of L. vulgaris were jigged from the shore in front of the Institute of Oceanography and Fisheries in Split, Croatia (northern Mediterranean Sea) in May 2002. After a short time in captivity the squids spawned spontaneously, leaving their strands on the water exchange pipe immersed in the pool. On day 21 after spawning, the first hatchlings were observed. The paralarvae were fed small fish pellets and brine shrimp Artemia salina in open circuit aquaria and glass pots, but died after eight days. For economic production and rearing, more sophisticated studies are needed, concentrating on nutritional requirements and balanced diet of early development stages.
