“…This shows that with the increase in dietary lipid level, the carcass lipid content also goes on increasing. Similar trend has also been found by [11]. Similarly, Du et al [12] reported that body lipid content of grass carp increased with increase in dietary lipid levels, indicating that this fish could deposit lipid in the muscle.…”

Present study was conducted to study the effect of varying level of dietary lipid on the growth, Feed conversion ratio (FCR) and body composition of the juveniles of Labeo rohita. Group of 25 juveniles in triplicate (average weight 0.022 gm ± 0.002 gm) were fed on three iso-nitrogenous experimental diets containing (40% protein) and varying levels of lipid i.e., 6%, 9% and 12% for a period of 60 days. Results revealed that the best increment in growth was obtained with 9% supplementary lipid (%WG 26.08 ± 0.681) followed by the diet containing 12% lipid (%WG 23.41 ± 1.646) and least with 6% lipid (%WG 22.71 ± 1.540). FCR and FCE shows inverse relation as highest value of FCE (9.35) and least value of FCR (10.70) was obtained in juveniles fed on 9% lipid diet with significant differences (p ≤ 0.001). Further biochemical analysis revealed that highest value of muscle lipid has been found in juveniles fed on 9% lipid diet i.e., 1.11 gm and least with diet containing 6% lipid i.e., 0.78 gm. Thus, based on the present results, it could be concluded that an artificial feed with 9% supplemented fish oil is sufficient without any adverse effects on growth performance and muscle quality.

“…The use of diet protein is related to both protein level and availability of non-protein energy sources. A number of studies have been conducted to determine the optimal diet protein level for some sparids fishes (Santinha et al 1996;Vergara et al 1996;Tibaldi et al 1996;Sá et al 2006) and have estimated 40-50% as the optimal diet protein level in terms of growth performance. Being the muscle the final product in fish farming it is surprising that there is very little work specifically linking diet protein level to muscle growth dynamics in juveniles.…”

Muscle cellularity was studied in Pagellus bogaraveo juveniles fed on diets with different protein contents. Measured in transversal body sections, at both post-opercular and post-anal locations, the morphometric variables estimated were: total muscle area (A), total number of fibres (N), number of fibres per unit area of muscle (N A ) and cross-sectional fibre area ð" aÞ; of the two main muscle fibre types. At the end of the experiment fish fed on diets having more than 40% of protein displayed significantly higher body weight. Fish fed on protein-rich diets exhibited greater " a and N. For fish fed on 30 and 50% protein diets the morphometric parameters measured grew linearly with the fish weight. High-protein diets favoured muscle hyperplasia. When comparing rostral and caudal locations, a greater N and a smaller " a of posterior red fibres were the consistent differences found-a fact, to our knowledge, so far unreported for fish.

“…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).
