“…In addition, the potential of some species for commercial aquaculture is high (Boucaud-Camou 1990;Hanlon et al 1991;Lee et al 1998). The cuttlefish (Sepia officinalis) can be included in this group (Forsythe et al 2002;Domingues et al 2006Domingues et al , 2007Domingues et al , 2008a.…”

The effects of culture density and bottom areas on cuttlefish (Sepia officinalis) culture were studied. Cuttle fish were cultured under three experimental combinations of culture density and bottom area: (1) high density and small bottom surface area; (2) low density and large bottom area; (3) high density and large bottom area. Each experimental protocol was repeated in triplicate. Average weights at the end of the experiment were of 65.8 ± 5.8, 87.1 ± 5.6 and 78.7 ± 5.9 g for cuttlefish cultured under the conditions of protocol 1, 2, and 3, respectively; these differences were significant between each of the three groups. Total biomass increased faster (up to 7.5 kg per tank) under the high density/ large bottom area conditions (protocol 3) due to the larger number of animals and low mortality in those tanks. Growth rates (%bw day -1 ) were different between protocols, with growth rates of 2.1 ± 0.1, 3.0 ± 0.2, and 2.5 ± 0.1%bw day -1 obtained for cuttlefish cultured according to protocol 1, 2, or 3, respectively. Average feeding rates were similar for the three groups-10.7 ± 0.8, 9.7 ± 2.0, and 9.6 ± 1.1%bw day -1 for cuttlefish cultured according to protocols 1, 2, and 3, respectively, while food conversions (%) were different-21.5 ± 3.2, 32.4 ± 2.5, and 27.0 ± 1.1%bw day -1 , respectively. Total mortality was high in the high density/small bottom area tanks, 30%, while it was very low for the groups cultured under conditions of low and high density/large bottom area, 4%. Based on these results, we conclude that culture conditions that provide large bottom areas also provide good survival conditions and promote growth in comparison those with small bottom areas, even under conditions of lower culture densities.

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.

RESUMEN.Durante 57 días se comparó el crecimiento y sobreviviencia de pulpos juveniles Octopus mimus del norte de Chile alimentados con tres diferentes dietas: dos dietas húmedas (A y B) aglutinadas con solución de gelatina embutidas en tripa de cordero y una dieta control (C) natural. La dieta (A) fue elaborada en base a una mezcla de filete triturado del pescado Cheilodactylus variegatus con harina de pellet para salmón, la dieta (B) con pasta de almeja (Protothaca thaca) mezclada con filete de Ch. variegatus y la dieta control consistió en el suministro de almejas frescas congeladas (C). Basado en un diseño experimental de medidas repetidas, los pulpos se mantuvieron individualmente en estanques de 70 L con circulación de agua de mar y aireación permanente. Los pulpos que consumieron la dieta B no experimentaron mortalidad y la dieta control C presentó mortalidad del 16,7%, sus crecimiento fueron similares (P > 0,05) con tasas de crecimiento absoluta (AGR) de 7,0 ± 0,91 (g d -1 ) y 6,6 ± 1,10 (g d -1) respectivamente. Los pulpos alimentados con la dieta A registraron mortalidad de 33,3% y tasa de crecimiento absoluta negativa, AGR= -1,70 ± 0,37 (g d -1). La dieta A que contenía como ingrediente pellet para salmón molido como harina no tuvo una adecuada aceptación y los ejemplares experimentaron disminución de su peso. La dieta B preparada con gelatina de origen animal como aglutinante, no implicó un efecto negativo en la palatabilidad y aceptabilidad en comparación al control basada en almeja fresca congelada, incluso los organismos lograron crecimientos similares. Los resultados permitirán a futuro mejorar la calidad nutricional de dietas artificiales para maximizar el crecimiento de O. mimus en cautiverio.

The growth and survival of juvenile octopus, Octopus mimus, from northern Chile, fed three different diets were analyze during 57 days. Two of the diets (A and B) were wet diets stuffed in lamb gut with a gelatin solution, and the third (C) was a natural control. Diet (A) was a mixture of chopped fish meat (Cheilodactylus variegatus) and pellets of salmon meal; diet B was made up of clam (Protothaca thaca) mixed with C. variegatus meat; and diet (C) (control) consisted of fresh frozen clams. The experimental design was based on repetitive measures; the octopuses were supported individually 70-L tanks, with constant sea water circulation and aeration. The octopuses fed diet B did not registred mortality, whereas those fed the control (diet C) presented a mortality of 16.7%. Growth rates were similar (P > 0.05) for these two groups, with absolute growth rates (AGR) of 7.0 ± 0.91 (g d -1) and 6.6 ± 1.10 (g d -1), respectively. The octopuses fed diet A had a mortality of 33.3% and an AGR of -1.70 ± 0.37 (g d -1 ). Diet A, which contained pellets of ground salmon meal, was not well-accepted, and the weight of the octopuses i...
