The current study was carried out to investigate the effects of dietary supplementation lysine and methionine on growth performance, approximate carcass compositions haematological biochemical parameters in common carp, Cyprinus carpio fingerlings (average weight 22 ± 0.9 g) for 10 weeks. Four experimental diets were prepared with supplemented at levels (0 (control diet), T1 (1Lys 0.4Met g/kg),...

the histology of digestive tract of caspian roach (rutilus rutilus caspicus) were studied for 53 days from hatching to fingerling size at the natural habitat of the larval stage. ages 1, 4, 10, 18, 28, 39 and 53 days after hatching (dah) were selected for the histological studies. after sampling and fixation with 10 percent formalin the histological process were conduct. the newly hatched larva...

Ahstracr.-This study evaluated the effects of dietary protein concentration (26, 28, and 32%) on growth. feed efficiency, processing yield, and body composition of USDA 103 and Mississippi “normal” (MN) strains of channel catfish raised in ponds. Fingerling channel catfish (average weight = 32.5 and 47.3 g/fish for USDA103 and MN strains, respectively) were stocked into 24 0.04-ha ponds (12 pon...

Flinders, J.M. and S.A. Bonar. 2007. Growth, condition, diet, and consumption rates of northern pike in three Arizona reservoirs. Lake Reserv. Manage. 24:99–111. Northern pike (Esox lucius L.) introductions are controversial in the western United States due to suspected impacts they might have on established sport fisheries and potential illegal introductions. Three Arizona reservoirs, Parker C...

An experiment was undertaken to develop a suitable seed production technique for Sperata aor in captivity. Naturally produced fry of aor was reared at different densities in nine nursery ponds 0.012 ha in size with an average depth of 0.8 m each. Three stocking densities tested, each of which was triplicated. Fry of aor stocked at 100,000/ha was designated as treatment-1 (T1), 150,000/ha as tre...
