THE POPULATION DYNAMIC OF BANANA PRAWN (Penaeus merguiensis de Man) IN TANAH LAUT WATERS, SOUTH KALIMANTAN
Abstract: Scientific advices
on population dynamic of banana prawn (P. merguiensis de Man) are required as
an input to support an apropriate fisheries management. This study aims to
identify the population parameters of the banana prawn in Tanah Laut waters.
The study was conducted in Tanah Laut based on monthly enumeration data
(January to November 2016). Results has been shown that the length size of
carapace at first maturity of banana prawn was 43.39 mm. Sex ratio of males and
females was 1 : 0.8. The chi square test indicated that comparison of male and
female of the banana prawn was significantly different. It means that there was
not balance in number between males and females. The spawning season of banana
prawn in Tanah Laut waters happened throughout year and reached the peak on
November (south-east monsoon). The growth parameter of banana prawn was
1.05/year with maximum carapace length (Loo) of 55.0 mm. Instantaneous total
mortality (Z) and natural mortality (M) were 6.05/year and 1.58/year,
respectively. While fishing mortality (F) and exploitation rate (E)
respectively were 4.47/year and 0.74/year respectively. The exploitation rate
of banana prawn in Tanah Laut waters was high. Therefore, fishing effort of the
banana prawn in that waters should be reduced to about 48 % for next coming
year.
