“…Similarly, Rodríguez et al (21), rearing gilthead sea bream larvae, observed that the best growth rate was achieved with a DHA:EPA ratio of about 1:3. Ibeas et al (22) obtained the best growth of gilthead sea bream larvae with a ratio of 2, while in the juvenile stage the best ratio was found to be 0.5. The highest DHA:EPA ratio found in the present study was 0.46 (treatment C with oil-enriched rotifers).…”

The effect of rotifers, Brachionus rotundiformis (S-type), fed three different diets: A (rotifer fed Nannochloropsis oculata), B (rotifer fed N. oculata and bakers yeast, 1:1), and C (rotifer fed N. oculata and bakers yeast, 1:1, and enriched with Selco â ), was evaluated based on the survival, growth and swim bladder inflation rate of fat snook larvae. Rotifers of treatment A had higher levels (4.58 mg/g dry weight) of eicosapentaenoic acid (EPA) than B (1.81 mg/g dry weight), and similar levels (0.04 and 0.06 mg/g dry weight, respectively) of docosahexaenoic acid (DHA). Rotifers of treatment C had the highest levels of EPA (13.2 mg/g dry weight) and DHA (6.08 mg/g dry weight). Fat snook eggs were obtained by spawning induction with human chorionic gonadotropin. Thirty hours after hatching, 30 larvae/ liter were stocked in black cylindric-conical tanks (36-liter capacity). After 14 days of culture, there were no significant differences among treatments. Mean standard length was 3.13 mm for treatment A, 3.17 mm for B, and 3.39 mm for C. Mean survival rates were very low (2.7% for treatment A, 2.3% for B, and 1.8% for C). Swim bladder inflation rates were 34.7% for treatment A, 27.1% for B, and 11.9% for C. The lack of differences in growth and survival among treatments showed that the improvement of the dietary value of rotifer may not have been sufficient to solve the problem of larval rearing. Some other factor, probably pertaining to the quality of the larvae, may have negatively influenced survival.

“…In small (larval) fish the ratio ranges between 4/1 to around 2/1 depending on species and study. In larger fish, the level appear to be more evened out, and ratios of around 1 have been reported in gilthead sea bream (Ibeas et al 1997). Deficiency in 22:6n-3 has been reported in several studies and…”

“…However, marine teleosts lack this ability due to an apparent deficiency of 5 desaturase required for the elongation and desaturation of this C18 precursor to 20 : 5n-3 (Sargent et al, , 1995. It has been shown that gilthead seabream Sparus aurata L. require 20 : 5n-3 and 22 : 6n-3 for healthy development (Koven et al, 1989(Koven et al, , 1990(Koven et al, , 1992Rodríguez et al, 1993Rodríguez et al, , 1994Ibeas et al, 1994Ibeas et al, , 1996Ibeas et al, , 1997Rodríguez, 1994). As in other marine fishes, gilthead seabream possess a very limited ability to elongate and desaturate linolenic acid, 18 : 3n-3 to 20 : 5n-3 and 22 : 6n-3 .…”

In female sea bream Sparus aurata fed a control diet (C), ovarian levels of neutral lipids (NL) and polar lipids (PL) remained constant between November and March, while a decrease in NL content was observed in liver and muscle. In the same period, liver PL content increased, while no changes were observed in muscle. Between March and June ovarian NL and PL showed a strong decrease, while NL remained constant in liver and muscle. When fish were fed a diet lacking in n-3 highly unsaturated fatty acids, n-3 HUFA (D), the pattern observed was similar to that found in the fish fed diet C, with the exception of liver NL, which increased between March and June. In general, the changes in fatty acid content, in both groups of fish, were highly influenced by the diet given to the broodstock, although these effects were greater on ovarian NL and PL than on liver and muscle lipids. Despite the fact that gilthead seabream females continue feeding during the spawning season, they probably make use of their liver and muscle reserves during the gonadal maturation process. Furthermore, the fatty acid composition of the broodstock diet was reflected in the body composition, especially in the ovaries. 2001 The Fisheries Society of the British Isles
