ABSTRACT
The length-weight relationship and condition factor were
studied for the obtained length range. Age-determination
and growth studies ‘were made from the examination and
measurements of the scales. The spawning season was appointed
and the probability of fractional or prolonged spawning
was discussed. The size and age at fjrst maturity were
studied. The absolute and relative fecundity were estimated
according to fish length, weight and age.
