“…Aguado-Giménez and García-García (2003) showed that O. vulgaris reached a growth rate higher than 1.5% day -1 when fed crab Macropipus depurator and Calappa granulata. More recently, Cerezo-Valverde et al (2008) reported a growth rate of 1.6% day -1 when animals were fed marine crab (Carcinus mediterraneus), suggesting that differences in the palatability, moisture, minerals and other dietary components could determine the advantages of marine crabs over other types of diet. In this study, we observed an inverse behavior: animals fed fish and squid had a growth rate higher than animals fed a fresh water crustacean.…”

The use of alternative prey (crayfish, Procambarus clarki, and hake, Merlucius gayi) to culture Octopus vulgaris (Cuvier 1797)

et al. 2009

The effects of two alternative prey (crayfish and hake) were tested on growth and survival of both juveniles and adults of Octopus vulgaris in two experiments. Octopuses fed the control (squid) were larger (3.0 ± 0.7 kg) than those fed crayfish (2.4 ± 0.6 kg) at the end of experiment I. Similarly, overall growth rates were higher for octopuses fed squid (1.7 ± 0.3 and 1.2 ± 0.2 %BW day -1 , respectively). Average feeding rates for the experiment were not different, being 6.5 ± 0.9 and 7.5 ± 0.9 %BW day -1 , respectively, for octopuses fed either squid or crayfish. Nevertheless, food conversions for the experiment were higher (42.4 ± 2.7%) for octopuses fed squid compared to the ones fed crayfish (23.9 ± 1.9 g). For experiment II, hake and crayfish were compared to squid; the final weight of octopuses fed squid, hake or crayfish was 1,183.0 ± 242.7 g, 1,175.6 ± 240.1 g and 922.3 ± 160.1 g, respectively. Overall growth rates for the experiment were 1.9 ± 0.2 %BW day -1 , 1.9 ± 0.3 %BW day -1 and 1.1 ± 0.3 g, respectively. Final weight and growth rates were never different (P [ 0.05) between octopuses fed squid and hake, but were always higher (P \ 0.05) compared to the ones fed crayfish. Average feeding rates for experiment II were similar for the three diets, and of 4.6 ± 1.5, 4.2 ± 1.3 %BW day -1 and 5.1 ± 0.9 %BW day -1 , respectively, for octopuses fed squid, hake or crayfish. Food conversions for experiment II were of 41.0 ± 9.6%, 40.5 ± 9.9% and 21.3 ± 7.4 g, respectively, for octopuses fed squid, hake or crayfish, and were always higher for octopuses fed squid and hake compared to crayfish. The results indicate that crayfish is not an adequate replacement for the usual prey to fatten octopus, even considering its much lower market price.

“…Recently, Cerezo et al (2008) with O. vulgaris, as well as Domingues et al (2007), Rosas et al (2007) and Aguila et al (2007) with the Yucatan octopus, Octopus maya, have been developing artificial diets for octopuses. So far, these diets have not promoted adequate growth.…”

“…This may be due to the lack of palatability of the diets or to their poor nutritional composition (Lee et al 1991;Castro et al 1993;Domingues 1999;Domingues et al 2005;Cerezo-Valverde et al 2008;Quintana et al 2008).…”

Influence of natural diet on growth and biochemical composition of Octopus vulgaris Cuvier, 1797

The influence of diet on growth and biochemical composition of cultured Octopus vulgaris was investigated. Octopuses were reared in a open recirculation seawater system and during the experiment were kept apart in cages. Experiment lasted 30 days. Three experimental dietary groups were established: group I (mixed diet: Carcinus mediterraneus, Boops boops and Mytilus galloprovincialis), group II (monodiet on B. boops) and group III (monodiet on M. galloprovincialis). The best results were obtained with the monodiet based on bogue that gave a weight gain of 390.65 ± 37.54, an absolute growth rate of 13.02 g day -1 and feed efficiency of 44.79 ± 0.96%. Regarding to biochemical composition, the mussel-fed and bogue-fed groups showed the highest protein content. Animals fed on bogue also showed the highest carbohydrate content, while the lowest value was observed in the mussels-fed group. The lipid content was found to be very low in all dietary groups. Saturated fatty acids were the most abundant fatty acid class, ranging from 58.22% in wild octopuses to 46.83% in bogues-fed octopuses. Polyunsaturated fatty acids (PUFAs) were the second most abundant fatty acids class in all dietary treatments (25.65-37.00% as a per cent of total FAs) except in octopuses fed with mussels. MUFAs ranged from 11.44 to 26.93% of total FAs. Although it is empirically known that a varied diet better covers the nutritional requirements than a monodiet, the results of this study reveal that a monodiet of B. boops may be used.

“…Dry or moist pellets (Castro 1990;Lee et al 1991;Castro et al 1993;Castro and Lee 1994) or surimi, a fish myofibrillar protein concentrate (Castro et al 1993;Castro and Lee 1994;Domingues 1999;Domingues et al 2005), was initially used with poor results (Castro et al 1993;Castro and Lee 1994;Domingues et al 2005Domingues et al , 2006. In the past 3 years, a greater effort has been made to develop artificial diets in several cephalopods, especially in O. vulgaris (Cerezo-Valverde et al 2008;Quintana et al 2008) and Octopus maya Rosas et al 2007). …”

“…The fattening of O. vulgaris is currently done in Galicia, North Spain (Iglesias et al 1997), but with low profitability due to the dependence on juveniles captured from the wild and the absence of an adequate artificial diet ). These are two of the major bottlenecks for the commercial aquaculture of this species, which are enhanced by the high mortality in the paralarvae stage of the octopus culture cycle (Iglesias et al 2007) and the impossibility of obtaining benthic juveniles on a commercial scale in captivity (Cerezo-Valverde et al 2008).…”

Lipid composition of the mantle and digestive gland of Octopus vulgaris juveniles (Cuvier, 1797) exposed to prolonged starvation

et al. 2010

Lipid composition of the mantle and digestive gland of Octopus vulgaris that were not fed for 27 days were determined. Every 3 days, three octopuses were killed and samples of the mantle and the digestive gland (DG) were taken, in order to determine total lipids as well as lipid classes and fatty acids. Composition in total lipids (TL) for the mantle was similar until day 21, then decreased and remained similar until the end of the experiment. Composition in total lipids for the DG decreased significantly after 3 days, then remained similar until day 21, and then decreased until the end of the experiment. As for the lipid classes, in the DG the main components were triglycerides and sterol esters. Sterol esters suffered strong reductions after 10 days of starvation, while triglycerides remained similar until day 21 and then decreased until the end of the experiment. Cholesterol decreased gradually throughout the experimental period. For polar lipids, phosphatidylcholine and phosphatidylethanolamine increased during the first 3 days and then decreased throughout the experiment. In the mantle, the only neutral classes that decrease were triacylglycerols and sterol esters, while no polar lipid classes decreased in this organ. It was noticeable the decrease in almost all fatty acids in the DG after 3 days of starvation, while in the mantle there were no differences in fatty acid concentrations during the experiment.
