...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...

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.

Fulton condition coefficient and LWR value indicated that sichel specimens’ were well adapted to the environmental conditions. Positive allometry in both males and females were observed (W = 0.004 L3.119). This represents the first LWR dataset for sichel. The morphometric and meristic traits values from this researc...

...ried out to describe the length-weight relationship (LWR), length-length relationships (LLRs) and
condition factor (K) in 926 specimens belonging to 20 freshwater fish species of family cyprinidae. Fish samples were
collected on a monthly basis from August 2013 to July 2014 at Taunsa barrage from the Indus River, Punjab,
Pakistan. The values of parameter b for LWRs ranged from 2.16 – 4.10 suggesting the isometric and allometric
