Abstract

The length weight relationship, the growth rates in length and weight as well as the condition factor of the fish are studied. Age determination and growth studies were deduced from the examination and measurement of scales. The spawning season was determined and the size, age at first maturity as well as sex ratio were investigated. The presence of different groups of ova in the ripe ovary indicates the probability of fractional or prolonged spawning habit. The absolute and relative fecundities were estimated according to fish length and weight. Analysis of stomach contents reveals the presence of polychaetes, crustaceans, molluscs, fishes, shelled protozoans and sand particles.
