DISTRIBUSI DAN POLA PERTUMBUHAN UDANG PUTIH (Penaeus merguiensis de Man) DI EKOSISTEM MANGROVE PERCUT SEI TUAN SUMATERA UTARA
ABSTRACT: White Shrimp
(Penaeus Merguiensis de Man) can be found almost in all Indonesian waters
especially in mangrove ecosystem ranging from river mouth, coastal water, to
open sea depends on their life stages. A research has been done within 12
months from January to December 2010 in Percut Sei Tuan North Sumatera aimed to
study spatial distribution of organism based on sex, size class, and gonad
maturity of female shrimp and to determine correlation of biophysical and
chemical characteristics of mangrove ecosystem with White Shrimp population
structures. The correlation can be used in analyzing important parameters
influencing abundance, spatial distribution, and growth pattern of the
organism. Habitat characteristic of white shrimp in each station as analyzed
using Principal Component Analysis while spatial distribution is analyzed using
Correspondence Analysis. Research results show that white shrimp caught in
Station 1 to 5 has smaller size compared to that in Station 6.The abundance of
mature female in this station is also higher which is principally determined by
high water temperature, depth, high water salinity, high substrate salinity,
high water pH, and high sand substrate. Growth pattern of White Shrimp in
mangrove ecosystem of Percut Sui Tan is allometric negative.
