Abstract

The purpose of the study to determine the distribution and growth patterns ofindo pacific tarpon fish (Megalops cyprinoides Broussonet, 1782) in Belawan River.This study was conducted in January-March 2014. Sampling was collected by purpo-sive sampling method. Sampling colected at 3 stations fishnet use with 30 times thestocking for each month. Distribution is calculated using the formula Khouw (2009)and the growth patterns using formulas King (1995). The results showed the analysisof Indo Pacific tarpon fish distribution uniform categorized months as earned valueid <1. Growth pattern of indo pacific tarpon fish is negative allometric means thelength faster than weight gain.

Abstract

Density and growth pattern mangrove clam Geloina erosa (Solander 1786) inmangrove ecosystem Belawan, has been investigated in December 2013 - February2014. G erosa samples taken from three observation stations and each station observa-tions were made 3 replicates (months) sampling. The method used in determining thesampling point is the "purposive sampling". G. erosa samples were collected directlyby capturing by hand at the lowest tide. Result of the analysis data was the highestdensity of G. erosa at station 1 Nypah fruticants vegetation average of 3.207 individ-uals/m 2 , the lowest Heterogeneous vegetation at station 2 average of 1.362 individuals/m 2 . Allometric growth patterns show a pattern of negative (b <3).

Abstract

The aims of this study were to determine density and distribution pattern of ki-jing (G. virens) in Belawan Mangrove Ecosystem. Sample were collected with a smallsquares 1x1 m 2 as much as 45 with interval 1 m. The results of this study showed thehighest value of the density was found in station III 2.93 Ind /m 2 , while at the station I2.80 Ind / m 2 . The lowest one was found in station II 1.16 Ind / m 2 . Distribution patternof Kijing on station I and II was uniform with id value 0.645 and 0.958, on the contra-vy on station III was clumped with id value 1.421.
