Ammonia nitrogen excretion rate - An index for evaluating protein quality of three feed fishes for the black sea turbot
Yigit, M; Koshio, S; Aral, O; Karaali, B; Karayucel, S (Lab Research Fish Diseases, 2003)Total ammonia nitrogen excretion rates were measured in young Black Sea turbot (74.79 g avg wt) reared in brackish water (17 ppt salinity) at 11+/-0.3degreesC. Duplicate groups of turbot were fed a fixed quantity of teleosts, ... -
Changes in blood ion levels and mortality rates in different sized rainbow trout (Oncorhynchus mykiss) following direct transfer to sea water
Plasma ion values and mortality rates were compared for 450 rainbow trout (Oncorhynchus mykiss) of three sizes following direct transfer from fresh water to Black Sea water of about 18 ppt. In fish of 14.29+/-0.30 g, plasma ... -
A comparison of the growth differences of rainbow trout (Oncorhynchus mykiss W., 1792) in freshwater and seawater (the Black Sea)
The research was carried out to determine the growth differences of rainbow trout in freshwater and seawater. Totally 480 individuals with initial mean weights of 88.08+/-0.91 g and 85.58+/-1.15 g were used in the experiment ... -
Growth and feed consumption of young rainbow trout (Oncorhynchus mykiss) exposed to different photoperiods
A feeding experiment was carried out in a brackish water (18 ppt) flow-through system to determine the effects of different photoperiods (light hours/dark hours; UD) on feed intake and growth performance of young rainbow ... -
Growth and feed utilization in juvenile black sea turbot (Psetta maeotica) under different photoperiod regimes
The effects of 4 different experimental photoperiod regimes, LDN (natural photoperiod), LD24:0 (24 h light:0 h dark), LD12:12 (12 h light: 12 h dark) and LDO:24 (0 h light:24 h dark),. on feed intake and growth parameters ... -
Nitrogen excretion patterns and postprandial ammonia profiles in Black Sea turbot (Scophthalmus Maeoticus) under controlled conditions
Yigit, M; Erdem, M; Aral, O; Karaali, B (Society of Israeli Aquaculture & Marine Biotechnology, 2005)Measurements of the rate of nitrogenous excretion were carried out in two batches of young Black Sea turbot (small 42 g, large 72 g) at 12 +/- 1 degrees C under natural light conditions (10 h light:14 In dark and 13 h ... -
Potential of poultry by-product meal as a substitute for fishmeal in diets for Black Sea turbot Scophthalmus maeoticus: Growth and nutrient utilization in winter
Turker, A; Yigit, M; Ergun, S; Karaali, B; Erteken, A (Israeli Journal of Aquaculture-Bamidgeh, 2005)The use of poultry by-product meal as an alternate dietary protein for Black Sea turbot Scophthalmus maeoticus (initial avg wt 18 g) in winter was evaluated. Triplicate groups of 15 fish were fed one of five isoenergetic ... -
The protein sparing effects of high lipid levels in diets for rainbow trout (Oncorhynchus mykiss, W. 1792) with special reference to reduction of total nitrogen excretion
This research sought to develop low-protein, high-energy (less-polluting) diets for rainbow trout to properly utilize protein and reduce total nitrogen excretion. Duplicate groups of rainbow trout were fed one of four ... -
Using ammonia nitrogen excretion rates as an index for evaluating protein quality of prawns in turbot (Psetta maeotica) nutrition
Yigit, M; Ergun, S; Turker, A; Karaali, B; Bilgin, S (Scientific Technical Research Council Turkey-Tubitak, 2005)Total ammonia nitrogen excretion rates were measured in Black Sea turbot (averaging 88.8 g) to compare the protein quality of prawns, the natural food of turbot, with that of the protein source commonly used in the feed ...
