  Comparison of the survival and growth performance in rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta fario) fry

  Kizak, Volkan; Guner, Yusuf; Turel, Murat; Can, Erkan; Kayim, Murathan

  Rainbow trout is an intensively cultured species because of their more cultivable character than brown trout. Culture of brown trout could not be expanded due to low growth performance of brown trout compared to rainbow trout. This experiment was conducted in a commercial trout farm, Aegean area (Turkey). Growth performances and survivals of rainbow and brown trouts from fry to fingerling was observed for 155 days. Growth performances, feed conversion rates (FCR) and survivals were determined. Initial weights of rainbow and brown trouts were 0.1 +/- 0.01 g. Final weights were 26.5 +/- 5.19 and 12.97 +/- 2.74 g, respectively at the end of the experiment. Survival and FCR of rainbow and brown trouts were 83.9, 80 and 0.59, 0.61% respectively. As a result, there is a similarity between these two trout species in point of survivals and FCR's although, growth performance was obviously better than brown trout in early development of rainbow trout.

  Levels of copper in liver, muscle and gill tissues in Capoeta trutta (Heckel, 1843) from Munzur River, Turkey

  Danabas, D.; Benzer, F.; Kaplan, O.; Yildirim, N. C.

  Heavy metal pollution of waters is a major environmental problem. Due to their toxicity, long persistence, bioaccumulative and nonbiodegradable properties in the food chain, heavy metals constitute a core group of aquatic pollutants. Capoeta trutta is an economically important fish and the object of significant commercial fishery in the Munzur River. Levels of Cu were measured in samples of the muscle, gill and liver tissues of C. trutta from Munzur River. In liver copper levels were higher at Station I (6.15 mg kg(-1)) polluted by domestic waste than Station II (5.48 mg kg(-1)) (P<0.05). The highest copper level (7.25 mg kg(-1)) was measured in muscle tissue at Station II. There was found no statically differences between stations in gill and muscle (P>0.05). It is suggested that ecological condition of freshwater fish and contamination levels in Munzur River must be regularly monitored.
