“…Since there was no observable symptoms of EFA deficiency such as fin erosion, a shock syndrome, myocarditis, reduced growth rate, reduced feed efficiency, and increased mortality [45,46] in any of the dietary treatments. It appears that the percentage of fishmeal contained in all diets provides a sufficient amount of EFA.…”

“…No apparent EFA deficient signs such as fin erosion and bacterial disease (Castell et al 1972) were observed during the feeding trial. The replacement of fish oil with palm oil in the diet of Clarias gariepinus did not significantly affect growth.…”

This study was conducted to investigate the effect of the substitution of fish oil with palm oil in the diet of Clarias gariepinus fingerlings over a 49 day period. Four diets were prepared with fish oil substituted with palm oil at 0% (control Diet 1), 25% (Diet 2), 50% (Diet 3) and 100% (Diet-4), using a completely randomised block design. Mortality was observed in all the treatments, while fish fed with 100% palm oil were most sluggish in accepting their feeds. Average weight gained, specific growth rate and feed conversion efficiency were not significantly affected by diet. It was concluded that palm oil can be substituted for fish oil in the diet of C. gariepinus.

“…For example, in the freshwater rainbow trout (Oncorhynchus mykiss)18:3n-3 alone can satisfy the EFA requirement, with 18:2n-6 only required for optimal growth [11]. However, in most marine species, including turbot (Scophthalmus maximus), the longer chain PUFA 20:5n-3 and 22:6n-3 are required [12].…”

The TF cell line, derived from a carnivorous marine teleost, the turbot (Scophthalmus maximus), is known to have a reduced rate of polyunsaturated fatty acid (PUFA) biosynthesis.In order to establish the enzymic step responsible, the metabolic conversions of a range of PUFA including the key intermediates of n-3PUFA metabolism, stearidonic acid (18:4n-3) and its elongation product 20:4n-3, were studied in TF cells and compared with the AS cell line derived from Atlantic salmon (Salmo salar). Cells were cultured in the presence of unlabelled (25 µM 3
