In this work, we study the variations in concentration (mg 100 g−1 dry weight) and total content (mg individual−1) of different lipid classes in muscle and the digestive gland of Octopus vulgaris during an 8‐day starvation period. In all the samples analysed, polar lipids (PL) predominated in muscle (267.3–337.2 mg 100 g−1) compared with neutral lipids (66.9–104.7 mg 100 g−1). A significant positive tendency was observed in muscle for the content and concentration of monoglycerides as a consequence of starvation (P < 0.05). Furthermore, a higher cholesterol (CHO) content was detected in this tissue after the fourth day of starvation compared with the fed animals (P < 0.05). Neutral lipids predominated in the digestive gland (12 958–14 151 mg 100 g−1) compared with PL (3157–6517 mg 100 g−1), with triglycerides, free fatty acids and monoglycerides being the major lipid classes. The concentration of PL and monoglycerides showed a positive trend with starvation, while the triacylglycerol showed a negative tendency (P < 0.05). The results suggest that triglycerides and CHO are transported simultaneously from the digestive gland to the muscular tissues during starvation and the preferential use of PL and CHO during growth phases. It was estimated that lipids contributed 26% of the energy costs of the animals during starvation, mainly in the form of triglycerides from the digestive gland.

“…In general, a decrease in food ingestion has been observed in ripe and broody females of different octopus species in captivity (Joll 1976, Wodinsky 1978, Mather 1980, Smale & Buchan 1981, as well as in the wild (Lo´pez-Uriarte et al 2010). This has been confirmed indirectly by a high incidence of ripe females with empty stomachs (Quetglas et al 2005) as well as by a decrease of energetic reserves in the digestive gland (OÕDor & Wells 1978, Cortez et al 1995, Zamora & Olivares 2004 and in muscle (Zamora & Olivares 2004).…”

“…Los lípidos como fosfolípidos y colesterol son solamente usados para la síntesis de membranas y hormonas esteroidales (Berger, 2010); pero la pérdida significativa de lípidos en la glándula digestiva de las hembras en el extenso ayuno fisiológico durante el cuidado de los huevos (Zamora & Olivares, 2004) y la disminución de ácidos grasos durante el ayuno experimental de O. vulgaris (García-Garrido et al, 2010), indican que los lípidos son fuente energética para el sostenimiento de los procesos vitales, en ausencia de ingesta de alimentos por tiempo prolongado. Sin embargo, en los calamares Sepioteuthis lessoniana y Photololigo sp.…”

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...
