| 總結: | Mullet spread through the tropical and subtropical area that can be found in the
coastal, brackish water up to fresh water. The objectives of this research were to know
the length-weight relationship and condition factor of mullet (Liza subviridis) inhabit in
Opak estuary, Bantul Regency. Totally 402 samples were collected using gill net
measure 1¼ to 3 inches every month from July 2012 to June 2013. Identification and
analyses of sample were conducted in the laboratory. Each mullet were measured for the
total length, body weight and sexed. The data were analyzed to determine the length and
weight distribution, length-weight relationship, and condition factor. The result showed
that total length of the male mullet was ranged 7.9-29 cm with weight ranged 5-325 g,
while total length of the female mullet was ranged 7.2-35.9 cm with weight ranged 3-
492 g. Both of male and female mullet have negative allometric growth, following the
equation W = 0.0141L
2.911
for male and W = 0.0198L
2.80
for female. Mostly of mullet
have good condition, with average of the condition factor was ranged 0.96-1.04 for
male, and 0.88-1.06 for female. Opak estuary predicted as the habitat of mullet, which
were used as feeding ground |
