...e. condition factor, length-weight relationship, K, L, to), 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-we...

...cluding the age, growth, length-weight relationship and reproduction. The study was conducted in upper Akcay River between June 2012 and May 2013. Monthly data showed that native fish chub were aboundantly with other native fish (Acanthobrama mirabilis) in upper Akcay River. The age distribution for both females and males of S. cephalus populationwas betweenI-VII, and the second age group was found at maximum rate of 30.60%. Their fork lengths an...

...with tradional method of length-weight relation (LWR) Equation and Artificial Neural Networks (ANNs) method. The growth estimation of 540 crayfish was carried out with both methods and the obtained results were compared. Then, the estimated values found via both examined methods. Coefficient correlation (r2), sum square error (SSE), mean absolute percentage error performance criteria (MAPE) were used for comparison of artificial neural network and l...

...dy was aimed to describe length-weight relationship and condition factor of 18 cat fish species belonging to five families of Indus River in Taunsa barrage from Punjab, Pakistan. The value of length weight relationship (LWR) equation and condition factor (K) ranged W= -0.249 TL0.79 – W= -2.803 TL3.55 and 0.07 – 1.69 respectively. The objective of this study was to determine LWR and condition factor of cat fish species of Indus River that could help...

...d out to investigate the length-weight relationship and condition factor of Coptodon guineensis from the New Calabar River and Buguma Creek, Nigeria. Assessments of the length and weight parameters indicated that the total length ranged from 12.4 cm to 29.8 cm with a mean value of 17.84±0.40 and the weight varied between 41g to 640g in subject collected from New Calabar River population. In Buguma Creek, the total length ranged from 10.9 cm to 23...

...o;b” values of the length-weight relationship among these five species were estimated as 2.442 (for L. navigator) and 3.007 (for P. marmoratus), respectively. Growth was found as isometric for P. marmoratus and C. aestuarii, and as negative allometric for L. depurator, L. navigator and E. verrucosa.
