Of three age groups (0⁺ to 2⁺), the fished stock belong from is primarily to the I⁺ age group (63.83⁄%) and 0⁺ age group (28.8%). Of five stomach fullness levels (0 to 4). the second and fourth degree made up significantly proportions, being 29.6% and 31.5%, respectively. For the five fat levels (0 to 4), the fourth degree made up 86.0%. The females to males ratio was 1.00 : 1.42. von Bertalanffy’s growth model followed the equation: Lt = 203.77 x (1 -e -03747(t+3.0272)).
