Cultivo intensivo de paralarvas de pulpo, Octopus vulgaris Cuvier, 1797, en tanques de 9 m³
The present paper describes a cultivation system of octopus, Octopus vulgaris Cuvier, 1797, paralarvae in 9 000 l tanks, at a density of 1 paralarva/l. Their diet consisted mainly of Artemia salina (L., 1756), with spider crab, Maja squinado Herbst, 1788, zoeas as a complement. During the two months...

| Sumario: | The present paper describes a cultivation system of octopus, Octopus vulgaris Cuvier, 1797, paralarvae in 9 000 l tanks, at a density of 1 paralarva/l. Their diet consisted mainly of Artemia salina (L., 1756), with spider crab, Maja squinado Herbst, 1788, zoeas as a complement. During the two months of cultivation trial, data on temperature, dissolved oxygen, and prey density were recorded. Paralarvae weight was sampled periodically, and analyses of proteins, total lipids, lipid classes and fatty acids of the prey and paralarvae were carried out, as well. At 56 days, the mean weight of the paralarvae was 9.21 mg (dry weight) and they had developed 17-18 suckers on each arm. The final survival rate was 0.2%. |
