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 ... -
Effects of photoperiod on growth and feed utilization of juvenile Black Sea turbot (Psetta maeotica)
Turker, A (Israeli Journal of Aquaculture-Bamidgeh, 2005)A study was conducted to determine the effect of different photoperiods on the growth and survival of juveniles of the Black Sea turbot (Psetta maeotica). Juvenile turbot (32.17 +/- 0.1 g) were reared under one of three ... -
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 ... -
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 ... -
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 ...
