Introduction Dietary protein is the most expensive ingredient in fish feed which is required to sustain normal growth of aquatic animals. Feed accounts for 40-60% of the production costs in aquaculture, with protein sources accounting for a significant proportion of this cost (Fotedar, 2004). The use of rich protein diets above optimum levels, increases operating costs required to raise fish. Op ...

Abstract An experiment was conducted to evaluate the effect of two different commercial feed additives on growth performance of monosex Nile tilapia fingerlings. Seven treatments were applied, three levels of Biogen® (0.1, 0.2 and 0.3%) and Pronifer® (0.1, 0.2 and 0.3%) in addition to control. The tested diets were applied in 21 fiberglass tanks each was stocked randomly with 20 monosex N ...

SUMMARY The protein requirements of fingerlings grey mullet, Mugil cephalus with an initial body weight of 5.5 g on the average, were studied by using four diets containing 32, 36, 40 and 44% crude protein, and fed for 90 days. The best growth performance was obtained with 36% crude protein and carbohydrate 35%, followed by the diets containing 40, 44 and 32% crude protein respectively. Protein e ...

  Abstract This research was conducted to study the effect of lipid levels on growth performance of fingerlings Sea bass. Sea bass (Dicentrarchus labrax) fingerlings with an average body weight 1.2±.0.2g were fed one of four compound diets containing 50% crude protein with different level of lipids, ranging from 10 to 16 g/100 g. The highest weight gain, specific growth rate, ...

ABSTRACT  In the two trials nine experimental diets of 25, 30 and 35% protein contents and within each level, three levels of metabolizable energy (ME) 2400, 2800 and 3200 kcal ME/kg representing nine P/E ratios ranged between 77.9 to 141.7 mg protein /kcal were tested. In the first trial red tilapia fry (0.70 - 0.82 g) and in the second experiment red tilapia fingerlings (9.06 - 9.59 g) wer ...

INTRODUCTION Gilthead sea bream production in Mediterranean countries  increased from 30 000 tons in 1996 to 90 000 tons in 2005,which mean that sale prices dropped considerably, from 6.6 € / kg in 1996 to 5 € / kg in 2005, with an historic minimum of 4 € / kg in 2002 (APROMAR, 2006). To maintain the profitability of gilthead sea bream farms, cutting production costs is necess ...
