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 ... -
Effect of natural and synthetic carotenoid sources on pigmentation of rainbow trout (Oncorhynchus mykiss)
A feeding trial was conducted to assess the effects of supplementing the diets of commercial-size rainbow trout (Oncorhynchus mykiss) with red pepper as a natural carotenoid source and synthetic astaxanthin. Diets without ... -
Effects of the levels of astaxanthin in the diet on the flesh pigmentation of rainbow trout
A feeding trial was conducted to study the effects of dietary astaxanthin concentration on muscle pigmentation of rainbow trout (Oncorhynchus mykiss) with a mean initial weight of 270 g fed diets supplemented with astaxanthin ... -
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 ... -
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 ... -
A study on some biological characteristics of Barbus plebejus escherichi Steindachner, 1897 in the Bafra-Altinkaya Dam Lake (Samsun, Turkey)
This research was carried out from November 1992 to November 1993 in the Altunkaya Dam Lake of Bafra of Samsun province. During the study, totally 236 Barbus plebejus escherichi Steindachner, 1897 were examined. The purpose ... -
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 ...
