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, ... -
Effect of environmental factors on biochemical composition and condition index in the medieterranean mussel (Mytilus gallaprovincialis Lamarck, 1819) in the Sinop region
Karayucel, S; Kaya, Y; Karayucel, I (Scientific Technical Research Council Turkey, 2003)Biochemical composition, condition indices, water temperature, salinity, seston, particulate organic matter and chlorophyll-a were monitored for 1 y. Wet meat volumetric condition index ranged from 23.96% to 47.43%, with ... -
The effect of environmental factors, depth and position on the growth and mortality of raft-cultured blue mussels (Mytilus edulis L.)
Karayucel, S; Karayucel, I (Blackwell Science Ltd, 2000)One-year-old rope grown blue mussels (Mytilus edulis L.) were grown in experimental lantern nets at two depths (2 and 6 m below the surface) in two different positions (inflow and outflow) off a raft in Loch Etive on the ... -
Effect of temperature on sex ratio in guppy Poecilia reticulata (Peters 1860)
Karayucel, I; Ak, O; Karayucel, S (Wiley, 2006)In this study, the effect of temperature on survival and sex ratios of guppy Poecilia reticulata (Peters 1860) was investigated. Treatments of 19, 21 and 22.5 degrees C low and 29, 32 and 35 degrees C high water temperature ... -
Estimating the carrying capacity of mussel raft systems in two Scottish sea lochs
Karayucel, S; Karayucel, I (Lab Research Fish Diseases, 1998)Two different carrying capacity models were applied to commercial mussel raft systems in two sea lochs on the west coast of Scotland. The mean currents were found to be 0.052 m/s in Loch Etive (LE) and 0.05 m/s in Loch ... -
Growth and mortality of mussels (Mytilus edulis L.) reared in lantern nets in Loch Kishorn, Scotland
Karayucel, S; Karayucel, I (Scientific Technical Research Council Turkey, 1999)One-year old rope grown mussels (Mytilus edulis L.) were held in experimental lantern nets at 2 m and 6 m depths in Loch Kishorn on the west coast of Scotland. Growth, mortality and shell morphology were monitored from May ... -
Growth and production in long-line cultivated Mediterranean mussel (Mylitus galloprovincialis) in Sinop, Black Sea
Karayucel, S; Karayucel, I; Erdem, M; Saygun, S; Uyan, O (Lab Research Fish Diseases, 2003)One-year rope-grown mussels (Mytilus galloprovincialis Lam.) with a mean length of 37.6+/-0.52 mm and live weight of 5.02+/-0.28 g were collected from fish farm mooring ropes and cultured in cotton or nylon socks in a ... -
Growth, production and biomass in raft cultivated blue mussels (Mytilus edulis L.) in two Scottish sea lochs
Karayucel, S; Karayucel, I (Lab Research Fish Diseases, 1999)Growth, biomass and production of one year old mussels (Mytilus edulis L.) were monitored in mussel raft systems over a 15 month experimental period in Loch Etive (LE) and Loch Kishorn (LK) on the west coast of Scotland. ... -
Influence of stock and site on growth, mortality and shell morphology in cultivated blue mussels (Mytilus edulis L.) in two scottish sea lochs
Karayucel, S; Karayucel, I (Lab Research Fish Diseases, 2000)One-year-old rope-grown blue mussels (Mytilus edulis L.) were held in experimental lantern nets and cross-transplanted between two sea lochs (Loch Etive and Loch Kishorn) on the west coast of Scotland. Growth, mortality ... -
Optimisation of UV treatment duration to induce haploid androgenesis in the Nile tilapia (Oreochromis niloticus L.)
Karayucel, I; Karayucel, S (Scientific Technical Research Council Turkey, 2003)The optimum UV duration times of eggs were examined in order to develop a simple and safe method for inducing androgenetic development in the Nile tilapia, Oreochromis niloticus. The yield of androgenetic haploid O. niloticus ... -
Production of androgenetic Nile tilapia, Oreochromis niloticus L.: Optimization of heat shock duration and application time to induce diploidy
Karayucel, S; Karayucel, I; Penman, D; McAndrew, B (Lab Research Fish Diseases, 2002)Diploid androgenetic Nile tilapia, Oreochromis niloticus, were produced using 5 min UV irradiation at 150 muW/cm and heat shock at 42.5degreesC for 3:30 min applied 25 min after fertilization. The survival rates to morula, ... -
Spat settlement and growth on a long-line culture system of the mussel, Mytilus galloprovincialis, in the Southern Black Sea
Karayucel, S; Erdem, M; Uyan, O; Saygun, S; Karayucel, I (Lab Research Fish Diseases, 2002)Spat settlement and growth at the depths of 3 and 7 m in a long-line mussel system in the southern Black Sea were determined in two seasons. The first spat collectors were hung in July 1997, the second in January 1998. ... -
Thermal and hormonal feminization of all male YY Nile tilapia, Oreochromis niloticus L.
Karayucel, I; Penman, D; Karayucel, S; McAndrew, B (Israeli Journal of Aquaculture-Bamidgeh, 2003)Hormonal and thermal sex reversal of YY male Oreochromis niloticus were compared. While similar percentages of females (34% and 32%, respectively) were produced, a significantly higher percent of intersex individuals (18.5%) ...
