Species morphometric of Anadara Shell in Tanjungbalai aquatic North Sumatera Province, Indonesia

Abstract

This research was conducted from October to November 2016 The samples was taken from 3 stations with repeating 3 times in Tanjungbalai Aquatic of North Sumatra Province. Regression equation for relationship length, height, and thickness of Anadara granosa, Anadara gubernaculum dan Anadara inaquivalvis shell to wet weight of flesh i.e Y = 2.950x - 1.3328, Y = 3.246x - 0.8254, Y = 3.01x - 0.5625, Y = 2.143x - 1.0492, Y = 2.2876x - 0.5419, Y = 1.7524 - 0.1926, Y = 2.6734x - 0.9413, Y = 2.6422x - 0.6525, Y = 2.315x - 0.2351. While for correlation coefficient relationship length with wet weight of A. granosa, A. gubernaculum, A. inaquivalvis of 0.796; 0.747; 0.899. Correlation coefficient height with wet weight were found of 0.821; 0.729; 0.909. Correlation coefficient thickness with wet weight of flesh were found of 0.798; 0.754; 0.910.
