“…Based on our current knowledge of marine fish nutrition, any formulated feed for cobia will have to be dependent, to some extent, upon global supplies of fish meal and fish oil (Tocher, 2003). Thus, studies have shown that 20-30% of fishmeal in cobia diets can be replaced by soybean meal without compromising growth performance but, at higher levels of substitution, growth can be significantly decreased (Chou et al, 2004;Zhou et al, 2005). Interestingly, and in contrast to salmonids, cobia do not appear to develop soybean mealinduced enteritis in the distal intestine (Romarheim et al, 2008).…”

In the present paper, we investigated the expression of fatty acyl desaturase and elongase genes in a marine teleost, cobia, a species of great interest due to its considerable aquaculture potential. A cDNA was cloned that, when expressed in yeast, was shown to result in desaturation of 18:3n-3 and 18:2n-6, indicating that it coded for a Δ6 desaturase enzyme. Very low desaturation of 20:4n-3 and 20:3n-6 indicated only trace Δ5 activity. Another cloned cDNA enabled elongation of 18:4n-3, 18:3n-6, 20:5n-3 and 20:4n-6 in the yeast expression system, indicating that it had C18-20 and C20-22 elongase activity. Sequence comparison and phylogenetic analysis confirmed that it was homologous to human ELOVL5 elongase. However, the cobia Elovl5 elongase also had low activity toward C24 HUFA. The cobia Δ6 desaturase had a preference for 18:3n-3, but the elongase was generally equally active with both n-3 and n-6 substrates. Expression of both genes was 1-2 orders of magnitude greater in brain than other tissues suggesting an important role, possibly to ensure sufficient docosahexaenoic acid (DHA, 22:6n-3) synthesis in neural tissues through elongation and desaturation of eicosapentaenoic acid (EPA; 20:5n-3).3

“…Lower weight gain, feed efficiency, and protein efficiency ratio at higher inclusion levels of SBM have been reported in juvenile cobia, Rachycentron canadum (Chou et al, 2004;Zhou et al, 2005), although specific effects on digestive function are not known. In more omnivorous and herbivorous fish species, adequately heat-treated SBM does not always negatively affect digestive function, as indicated by weight gains, protein efficiency ratio (PER), net protein utilization (NPU), and/or protein and energy retention, in common carp, Cyprinus carpio (Viola et al, 1982), various tilapia (Oreochromis) species (Davis and Stickney, 1978;Shiau et al, 1987;El-Sayed, 1999), channel catfish, Ictalurus punctatus (Peres et al, 2003), and pacu, Piaractus mesopotamicus (Ostaszewska et al, 2005).…”

“…Soybean meal (SBM) is widely known to be a costeffective alternative for high-quality FM in diets for many aquaculture species because of its high protein content, relatively well-balanced amino acid profiles, reasonable price, and steady supply (Lovell 1988;Chou et al 2004). Lovell (1988) reported that SBM has one of the best amino acid profiles of any plant protein feedstuff.…”

Use of Turkey Meal as a Replacement for Menhaden Fish Meal in Practical Diets for Sunshine Bass Grown in Cages

et al. 2007

Abstract.-A 391-d feeding trial was conducted with caged juvenile (mean weight ¼ 36.2 g, SD ¼ 8.04 g) sunshine bass (female white bass Morone chrysops 3 male striped bass M. saxatilis) to evaluate growth, feed conversion, protein efficiency ratio, body composition, and fillet composition resulting from diets with decreasing levels of fish meal (FM; 30, 20, 10, and 0%) and increasing levels of turkey meal (TM; 0.0, 9.7, 17.5, and 26.4%). We stocked 100 randomly selected fish into each of 12 floating cages (3.5 m 3 ). Twice daily, fish were fed all they could consume in 30 min. Four practical diets were formulated to contain 40% protein and to be isoenergetic. After 391 d, significant (P 0.05) differences were found in growth; fish fed the control diet (30% FM, 0% TM) had higher individual final weight, percent weight gain, and specific growth rate than fish fed 10.0% FM and 17.5% TM. However, differences for those variables were not apparent between the control group and fish fed the 20% FM and 9.7% TM diet or the 0% FM and 26.4% TM diet. Diet composition did not significantly alter amount of diet fed, feed conversion ratio, protein efficiency ratio, percent survival, fillet yield, or hepatosomatic index among treatments. Results indicate that sunshine bass grown in cages for 391 d can be fed a diet containing 0% FM and 26.4% TM without adverse effects on growth, feed conversion ratio, and body composition; more diverse diet formulations for sunshine bass and reduced usage of menhaden fish meal are therefore possible.
