Abstract
This study highlighted the Stock assessment of three Carangid species Carangoides ferdau, Carangoides malabaricus and Gnathanodon speciosus from the Hurghada, Red Sea, Egypt. A total sample of 192 specimens (125-542mm SL) of C. ferdau, 279 specimens of C. malabaricus (145-460mm SL), 193 specimens of G. speciosus (110-503mm SL) investigated items included the length- weight relationships, condition factor, growth and mortality, exploitation ratios, and annual recruitment patterns. The results showed that the correlation of total length and standard length is best described by linear regression, while the length-weight analyses showed best described by the power function equations for three species. The weight of the fish increased as the fish length increased for C. ferdau, C. malabaricus and G. speciosus giving the best correlation coefficient (R=0.98) for the third one. The variations of condition factors (Kc and Kn) according to length groups and the monthly variations seemed to be weak. The age composition as estimated from otolith readings. It was noticed that C. ferdau and G. speciosus attained 9 age groups from I to IX years old, while the age composition of C. malabaricus, was 7 age groups from 0 to VII years old. The most dominant age group in the catch was the second age group for C. malabaricus and G. speciosus forming 26.91%, 20.96% respectively of the total catch. While in C. ferdau most dominant age group in the catch was the third (III) age group forming 36.26% of the total catch. The growth parameters were estimated as L∞= 747.13, 676.42, 525.2mm SL, K=0.12, 0.13, 0.18 and to=-0.82, -1.00, -1.08 years for C. ferdau, C. malabaricus and G. speciosus, respectively. The estimated growth performance index (Ø) was 2.91, 2.93, 3.23 for three species respectively. Total mortality (Z) was calculated as 2.09, 2.13 and 2.21 year-1 respectively. Natural mortality (M) was estimated as average 0.405, 0.465 and 0.460 year-1 respectively. The Exploitation ratio of the three species exceeded the optimum exploitation (E=0.5), indicating that overfishing is occurring. From the maturity observation, the spawning season extended from June to September with a peak in July for C. ferdau and G. speciosus while for C. malabricus, the spawning season started in May to September with a peak in August. This study recommends the reduction of the fishing efforts considering the length at sexual maturity doesn't exceed the length at first capture.
