Kepadatan, Distribusi dan Hubungan Panjang Berat Remis (Corbicula Javanica) di Perairan Pantai Putra Deli Kabupaten Deli Serdang

Abstract

Corbicula javanica is a group of small shellfish that live at the bottom of the waters. have shells, mollusca phylum of the corbiculidae family and bivalves class that live in coastal waters. Mussels are an important component in aquatic ecosystems as a component of the food chain or an indicator of water quality monitoring. Mussels are often found in Putra Deli Beach Waters. Mussels have high economic and nutritional value so that many people take them continuously to be bought and sold in traditional markets. Mussels are collected continuously without considering the size that can affect their presence and growth in nature. This study aims to determine the density, distribution pattern, length-weight relationship, and relationship between physicochemical factors in the waters and the distribution of mussels. This study used the "Purposive Sampling" method, namely simple random sampling. The research results obtained the highest density value at station 2, namely 1,2 ind/m2 and the lowest at station 3, namely 0,9 ind/m2. Distribution index values ranged from 3.0 to 3.2 with a clustered distribution pattern. The relationship between mussel length length from each station was negative allometric (b<3), which means that the growth of mussel shell length was more dominant than the growth of mussel body weight. The results of the correlation analysis showed that light intensity,BOD and pH were water chemistry glass factors that had a very strong influence on the density of mussels
