“…This is the specific lipid profile for A. japonica because only some mollusks, such as abalone and snails 25, 34, 35 , show noticeable levels of 22:5n-3. High levels of 22:5n-3 in A. japonica lipids indicate its biosynthetic weakness of DHA, similar to those in the mollusks 25,34,35 and other freshwater fishes 8,33 .…”

“…Asam lemak esensial tidak dapat disintesa oleh tubuh biota melainkan harus disuplai dari pakan. PUFA (Polyunsaturated Fatty Acid) dibutuhkan untuk pertumbuhan normal dan reproduksi abalon yang harus didapatkan dari pakan sebagai asam lemak esensial (Dunstan et al, 1996).…”

ABSTRAKOptimalisasi pemeliharaan yuwana abalon telah dilakukan dengan tiga berbeda kepadatan dan memanfaatkan tiga jenis rumput laut. Tujuan penelitian ini adalah untuk memperoleh teknik pemeliharaan yuwana abalon H. squamata yang efisien dan aplikatif melalui kepadatan dan jenis pakan yang berbeda. Digunakan yuwana abalon dengan ukuran panjang cangkang awal 7,8-10,1 mm; kepadatan yuwana awal yaitu 500, 250, dan 125 ekor/keranjang, dan jenis pakan yang berbeda yaitu Ulva sp., Gracilaria sp. asal laut, dan Gracilaria sp. asal tambak. Hasil yang dicapai pada akhir penelitian menunjukkan pengaruh yang nyata (P<0,05) terhadap pertumbuhan panjang cangkang, di mana pada perlakuan (A) 500 ekor + Gracilaria asal tambak sebesar 15,07±3,08 mm; (B) 500 ekor + Ulva sebesar 13,58±2,65 mm; (C) 500 ekor + Gracilaria asal laut sebesar

“…The same authors were also able to demonstrate that H. fulgens abalone fed a lipid-free diet grow in a similar way than those fed a 5% lipid diet without any adaptaciones alimenticias y estrategias de manejo acuícola. Por ello, la formulación efectiva de alimentos balanceados no sólo es importante para lograr mejores crecimientos, sino también para asegurar un suministro constante de alimento (Dunstan et al 1996).…”

The effect of feeding different levels of n3 highly unsaturated fatty acids (HUFA) on the fatty acid profile was evaluated in soft tissue from juvenile Haliotis tuberculata coccinea. Five diets were formulated with different oil sources (palm, colza, fish, sunflower, and soybean), containing from 2.52% to 12.33% n3 HUFA, while fresh Ulva rigida was used as reference diet. The different diets were provided to groups of 20 abalone during 120 days in independent triplicates. Though no significant differences in growth (P < 0.05) were registered among all formulated diets, a tendency to accumulate different fatty acids in muscle was observed. The proximate composition of abalone tissue showed that the diet containing 6.8% HUFA resulted in higher lipid accumulation in muscle tissue than that observed in the other treatments. Our results suggest that H. tuberculata coccinea, contrary to to abalone species from colder environments, does not have high HUFA requirements; however, the fatty acid profile of muscle and viscera tissues of abalone may be modulated by the fatty acid content in diets.Key words: abalone, fatty acids, lipids, n3 HUFA, nutrition. ResumenSe evaluó el efecto de diferentes niveles de ácidos grasos altamente insaturados (HUFAs, por sus siglas en inglés) n3 en el perfil de ácidos grasos de los tejidos blandos de juveniles de Haliotis tuberculata coccinea. Se formularon 5 dietas con diferentes fuentes de aceite (palma, colza, pescado, semilla de girasol y soya), que contenían de 2.52% a 12.33% de HUFA n3, usando Ulva rigida como dieta de referencia. Las diferentes dietas se suminitraron a grupos de 20 abulones durante 120 días por triplicado. Aunque no se registraron diferencias significativas en el crecimiento (P < 0.05) entre todas las dietas formuladas, se observó una tendencia a acumular diferentes ácidos grasos en el músculo de los organismos. La composición proximal del tejido de los abulones mostró que la dieta que contenía 6.8% de HUFAs dío como resultado mayor acumulación de lípidos en el tejido muscular que la observada en los otros tratamientos. Los resultados de este trabajo sugieren que H. tuberculata coccinea, a diferencia de algunas especies de abulón de ambientes más fríos, no requiere HUFAs; sin embargo, el perfil de ácidos grasos de los tejidos muscular y visceral del abulón puede estar regulado por el contenido de ácidos grasos en su dieta.Palabras clave: abulón, ácidos grasos, HUFA n3, lípidos, nutrición.
