“…A positive relationship has been observed in several species, such as seabream (Salhi et al 1994) and red seabream, Pagrus major (Temminck and Schlegel, 1843) (Watanabe et al 1989;Watanabe 1993), but other studies conducted also with seabream (Koven et al 1990;Koven et al 1992;Pousão-Ferreira et al 1999) and turbot Reitan et al 1994;Estévez et al 1999) failed to demonstrate such a relationship. The results of previous studies (Morais et al 2004;Villalta et al 2005) appeared to support a lack of correlation between the prey's HUFA, particularly DHA, concentration and larval survival in Senegalese sole.…”

Lack of essential fatty acids in live feed during larval and post-larval rearing: effect on the performance of juvenile Solea senegalensis

Despite the large progress obtained in recent years, Senegalese sole (Solea senegalensis) production of high quality juveniles is still a bottleneck. This paper examines the effect of larval and post-larval lipid nutrition on juvenile performance and quality. Four dietary treatments were tested: A-enriched Artemia spp. (EA); B-non-enriched Artemia spp. (NEA); C-EA during the pelagic larval period and NEA after larval settlement; D-50% EA and 50% NEA. Juvenile fatty acid profile at 60 days after hatching (DAH) clearly reflected the larval and post-larval diet composition. Feeding sole larvae on NEA (poor in lipids and essential fatty acids-EFA) had a negative effect, reducing growth (total length and dry weight) after 30 DAH and decreasing digestive enzyme activity at the end of the rearing period (60 DAH). However, relatively good performance compared to the EFA-richest treatment (A) was obtained when larvae were fed 50% EA and 50% NEA (D) or even EA only during the pelagic larval period followed by NEA after larval settlement (C). Malpigmentation was not affected by the dietary regimes and its incidence was very low. However, skeletal deformities were prevalent, particularly in the caudal complex, independently of diet. The results confirm that Senegalese sole appear to have lower larval EFA requirements than most cultured marine species and potentially even lower requirements during the post-larval stage. The importance of studying the impact of early nutrition on later juvenile stages was clearly highlighted in this study.

“…The reaction of a given species to various lipid levels can also depend on developmental stage. Lipid levels ranging from 12 to 20% were not seen to have an effect on the growth rates of larval gilthead sea bream Sparus aurata (Salhi et al, 1994), but increasing lipid levels from 9 to 15% significantly improved the growth rate of juvenile stages of this species (Vergara, 1996). Percid fishes are particularly sensitive to oxidised lipids in feed.…”

ABSTRACT:The aim of the experiment was to determine the effect of graded lipid content in experimental isoprotein feed (6, 10, 14% lipids and 45% protein) on the growth performance of juvenile pikeperch (initial body weight ≈ 210 g) in a recirculation system. No significant effect of the applied feed on the final average body weight was observed. However, average daily weight gain (g/d), SGR index (%/d) and condition coefficient of the fish receiving 10% lipid feed were significantly higher than the corresponding values in the other two groups (6 and 14% lipid, P < 0.05). Feed conversion ratio (FCR) and protein efficiency ratio (PER) a�ained the most advantageous values in this group of fish. The application of the experimental feed had a significant effect on the lipid values in fish bodies and viscera (P < 0.05) although no relationship was detected between the lipid content of the feed and that of the fish muscles. The lipid content was approximately 7.7% in all the experimental groups and the differences between the groups were statistically insignificant (P > 0.05).

“…Por otro lado, se ha logrado determinar que cuando las larvas son cultivadas en agua dulce, los requerimientos de una relación EPA/DHA son más favorables a EPA que DHA, pero que cuando son cultivadas a 15‰, los requerimientos aparentemente son más favorables a DHA. Evidencias de una mayor importancia del DHA sobre el EPA en ambientes marinos han sido mencionados anteriormente (Hernández-Cruz et al, 1994) concordando con lo encontrado en este trabajo. Sin embargo, evidencias de una mayor importancia del EPA sobre el DHA en agua dulce son escasas.…”
