“…Similarly, Rodríguez et al (2006) observed that at a high initial density (24.5 kg m -3 ) octopuses kept in cages consumed low amounts of food. Additionally, they observed a high incidence of skin lesions, which were more likely to occur due to friction with the cage walls and/or interactions among octopuses in a high-density culture.…”

“…Numerous studies have analyzed physiological and nutritional aspects of octopus ongrowing in tanks, but all of them used one individual per tank García and Cerezo, 2006). Other studies have evaluated factors such as stocking density using cages suspended from rafts (Chapela et al, 2006) or floating cages (Rodríguez et al, 2006).…”

SUMMARY: To assess the possibility of O. vulgaris ongrowing using tanks or cages in the bays of the Ebro Delta, we performed several growth trials of common octopus held in tanks. Effects of environmental factors (temperature and salinity) and zootechnical aspects (culture density) were studied. The thermal ranges that defined positive growth periods in the bays of the Ebro Delta were 19.5ºC to 23ºC (spring-summer) and 23.5ºC to 12.3ºC (autumn-winter), the latter being the most suitable period for ongrowing. Salinity did not affect survival (100%) or growth within the range tested (34-29 psu), though feeding rates (AFR, SFR) were directly related to salinity. On the other hand, after 60 days, final culture density increased three-fold (D1: 12.36 → 44.37 kg m -3 ; D2: 24.13 → 67.76 kg m -3 ), with optimal survival results (>90%) for the two densities tested. Growth and feeding rates showed a slight inverse relationship with density. Finally, growth and feeding rates showed a clear dependence on temperature in the two experiments (density and salinity). Our results conclude that industrial production of O. vulgaris in tanks is promising: this system offers an alternative to cages and allows for a more exhaustive control of culture.Keywords: Octopus vulgaris, growth, ongrowing, temperature, salinity, culture density. (Cuvier, 1797) en tanque en el Delta del Ebro (NE España): Efectos de la temperatura, salinidad y densidad de cultivo. -Con el fin de evaluar la posibilidad de engorde de O. vulgaris en tanques o jaulas en las bahías del Delta del Ebro, se llevaron a cabo varias experiencias de crecimiento de individuos mantenidos en tanques. Se estudiaron tanto aspectos medioambientales (temperatura y salinidad) como zootécnicos (densidad de cultivo). Los rangos térmicos que definieron periodos positivos de crecimiento en las bahías del Delta del Ebro fueron: 19.5ºC-23ºC (primavera-verano) y 23.5ºC-12.3ºC (otoño-invierno), siendo este último el periodo más favorable para el engorde. La salinidad no afectó a la supervivencia o al crecimiento dentro del rango testado (34-29 psu), a pesar de que las tasas de alimentación (AFR, SFR) mantuviesen relación directa con la salinidad. Por otro lado, y transcurridos 60 días, observamos que la densidad de cultivo se multiplicó por tres (D1: 12.36 → 44.37 kg m -3 ; D2: 24.13 → 67.76 kg m -3 ), con resultados óptimos de supervivencia (>90%) bajo las dos condiciones probadas. Las tasas de crecimiento y alimentación mostraron una relación indirecta con la densidad de cultivo. Finalmente, se observó que tanto las tasas de crecimiento como las de alimentación presentan una clara dependencia de la temperatura en ambas experiencias (salinidad y densidad de cultivo). Nuestros resultados concluyen que la producción industrial de O. vulgaris en tanques es prometedora: este sistema ofrece una alternativa a las cajas y permite un control más exhaustivo del cultivo.

“…En España, las experiencias de crecimiento de juveniles y subadultos de O. vulgaris capturados en la naturaleza han permitido demostrar que sus tasas de conversión y crecimiento diario son altas. Animales con un peso inicial de aproximadamente 700 g colocados en jaulas flotantes alcanzan un peso de 2 a 3 kg después de 3 a 4 meses, lo que permite incrementar su rentabilidad en el mercado considerando que los ejemplares de mayor tamaño alcanzan mejores precios (Domingues et al, 2004;Iglesias et al, 2004Iglesias et al, , 2007Rodríguez et al, 2006;García-García & Cerezo, 2006). También, en Portugal (Sendao et al, 1998) e Italia (Cagnetta & Sublimi, 2000) en experiencias de alimentación de O. vulgaris basadas en presas frescas permitieron constatar mayor crecimiento de los pulpos alimentados solamente con crustáceos.…”

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...

“…Crayfish (P. clarkii) and sardine (S. pilchardus) are two possible alternative preys to shrimps, due to their lower price. Although sardine is not an optimal diet for cephalopods, recent studies have reported that sardine is routinely used for octopus commercial culture, indicating that this type of diet could be an alternative for cephalopods culture (Iglesias et al 2000(Iglesias et al , 2004Rodríguez et al 2006;Vaz-Pires et al 2004).…”

The effects of feeding three natural frozen diets, grass shrimp (Palaemonetes sp.), crayfish (Procambarus clarkii) and fish (Sardina pilchardus) and two semi-humid artificial diets (based on fish powder) to mature cuttlefish, Sepia officinalis, were analysed. Growth and feeding rates (GR and FR, % BW day -1 ), food conversions (FC, %), and total protein and lipid composition of the diets were determined. Digestive gland to body weight ratio and absorption efficiency were calculated for each diet. Cuttlefish fed shrimp and crayfish grew larger (1.5 and 1.1% BW day -1 , respectively) compared to the other diets. Shrimp promoted the highest FC, followed by crayfish, and sardine. The highest FR was obtained for cuttlefish fed crayfish (8.4% BW day -1 ). Although both artificial diets were accepted, none produced growth. A positive correlation (r = 0.96) between cuttlefish ingestion rate and digestive gland weight was obtained. Some cannibalism occurred among cuttlefish fed the artificial diets during the last week of the experiment. According to the results obtained, P. clarkii could be used as an alternative prey to shrimp for rearing adult mature ([50 g) S. officinalis.
