ABSTRACT
Miswar BUDI MULYA. Bioecological Study White Shrimp
Penaeus merguiensis
de Man.
Under direction of
DIETRIECH G. BENGEN,
RICHARDUS F. KASWADJI, and ETTY RIANI.
White shrimp abundance is greatly influenced by food availability, existence of predators and competitors, as well as by characteristics of mangrove
habitat. Changes in habitat quality in mangrove ecosystem directly affects the growth of this biota. The objective of the research were to determine suitable
habitat characteristics of white shrimp based on maturity stage, and to determine spawning peak season and recruitment of white shrimp in mangrove ecosystem of
Percut Sei Tuan North Sumatera. White shrimp habitat characteristics was evaluated based on biophysical and chemical parameters of environment at each
station using
principal component analysis. Spatio-temporal distribution was
evaluated based on gonads maturity index using correspondence analysis.
Temporal distribution of female white shrimp was evaluated based on the maturity of gonads in each observation month.
Correlation
a
nalysis of white shrimp spatial distribution with size, sex, gonads maturity, and mangrove species at each
stationzone was also performed.
P
rincipal component analysis results described that correlation between parameters centered on two main axes, each explaining
76.27 and 17.62 of total range.
The
analysis classified three groups of individualsstation.
Group I consisted stations 1, 2, and 3 characterized by dissolved oxygen, nitrate, phosphate, current speed, and clay substrate.
Group II consisted stations 4 and 5 characterized by mangrove density, litter production,
plankton abundance and macrozoobenthos, and high litter decomposition rates.
Group III consisted of six stations characterized by water temperature, brightness, depth, salinity, pH, and high sand substrate.
Analysis of white shrimp spatial distribution based on gonads maturity level using
correspondence analysis showed information which centered on two main axes, each explaining
65.17 and 28.60 of total range. Analysis results also showed female adult white shrimps with mature gonads were found in waters which have temperature
