The respective exponential equation for the length-weight relationship was W = 0.068[L]2.5 for S. galilaeus and W = 0.034[L]2.7 for O. niloticus which shows that both species exhibited negative allometric growth (b < 3.0). The correlation coefficient (r) and condition factor (K) recorded ...
The relative values for Kn was determined by using equation. Obtained values for Kn were ranged between 0.9 to 1.18 for males and 0.8 to 1.16 for females.Keywords : Lepturacanthus savala, Length Frequency, Length-Weight relationship, Ribbon fish, RelativeCondition Factor 展开 ...
Effects of length and condition factor on emigration rates of hatchery-reared smolts of winter steelhead (Oncorhynchus mykiss) stocked 4.7 km upstream of a permanent fish trap were examined. For three releases, an average of 19.8% of fish did not emigrate past the trap. Fish with fork lengths...
Lake Mariut, Egypt A comparative study of the length-weight equation and the condition factor of Tilapia zillii from Lake Mariut, EgyptA comparative study of the length-weight equation and the condition factor of Tilapia zillii from Lake Mariut, EgyptThe length-weight relationship of Tilapia zillii...
The parameters "a" and "b" of the length-weight relationship were estimated using the formula W= alb while the condition factor was calculated from the equation K = W100 L-3. The "b" values for the males, females and combined sexes were 1.2713, 2.8412 and 1.8776, respectively. The ...
Oocyte count was repeated three times (three 1-ml subsamples taken and counted from each fish), and the calculated mean was multiplied by the dilution factor to estimate fertility. To evaluate the correlation of body size and HSI to fecundity, the partial correlation coefficients were used. ...
Condition factors calculated on the basis of weight and length are not a satisfactory index of fatness and a new index called a "fat factor" (F) is described. This is related to the specific gravity (G) of a fish by the equation F = G/(G 1). Seasonal trends in F and a high pos...
Previous studies evaluating the correlation between mercury and fish condition have not considered the rate of fish growth as a factor that may influence this relation. In the present study, we examine fish condition, growth rate, and mercury concentration in northern pike from 26 lakes in the we...
We study positive solutions of a logistic elliptic equation with a nonlinear boundary condition that models coastal fishery harvesting ([18]). An essential role is played by the smallest eigenvalue of the Dirichlet eigenvalue problem, in terms of which, a noncritical case is studied in [32]....
Length-weight, length-length relationships and condition factor of male, female and combined sex of Oreochromis niloticus in Gbedikere Lake, Bassa, Kogi State was studied. Seventy fish samples of total length ranging from 7.97cm to 19.50cm and weight between 20.8g and 309.4g collected between Ju...
