Population structure and growth pattern of wild oyster (Ostreidae) in Banda Aceh City, Aceh Province, Indonesia

Abstract

The aim of the study was to analyze population structure, growth patterns and determine the environmental conditions of wild oyster habitat that grows in Banda Aceh City, Indonesia. The study was conducted from April to May 2017 in three locations that represent the wild oyste habitat in Banda Aceh City, Indonesia. The study locations are Alue Naga, Gano and Gampong Pande.

The most common oyster species was Crasosstrea irredelei. The highest density was observed in the Gampong Pande waters and the lowest in the Gano waters, respectively. The pattern of oyster distributionwas found in clustered and formed oyster reef. The negative allometric growth pattern was observed in the oyster species. The environmental conditions consisted of plankton abundance and chemical-phisical parameters of the waters of Banda Aceh City have a normal carrying capacity for oysters to grow.
