Growth,mortality,recruitment and yield of rainbow trout,Oncorhynchus mykiss Walbaum,1792 in Karacaören-I Dam Lake,Turkey

In this study,growth parameters (i.e. condition factor,length-weight relationship,k,lcopyright 2017 zoological society of pakistan∞,t0),mortality rate (z,m,and f),recruitment pattern and yield were investigated for oncorhynchus mykiss in karacaören i dam lake. fish were collected on monthly basis between july,2013 and june,2014. growth parameters were analyzed by elefan with monthly length-frequency data. the b values of the length-weight relationship,mean condition factor,k (growth coefficient),l∞ (asymptotic length) and t were estimated as 3.207,1.13,0.33 year-1,36.50 cm and -0.476 years,respectively. total mortality (z) by length-converted catch curve was estimated at 0.83 year-1,fshing mortality (f) 0.14year-1,natural mortality (m) 0.69 year-1 and exploitation rate (e) 0.17. according to the result of relative yield/recruit analysis estimated e >e,so in this context stock of o. mykiss was not overexploited in karacaören i dam lake. copyright 2017 zoological society of pakistan.
