The length-weight relationship and condition factor of Toothpony (Gazza minuta Bloch, 1795) from Pabean Bay, Indramayu, West Java

Abstract

The purpose of this study is to specify the length-weight relationship and to evaluate the relative condition factor of toothpony (Gazza minuta Bloch 1795) in Pabean Bay, Indramayu, West Java. The fish collection was carried out monthly from January 2016 to December 2016, and a total of 190 individual fishes were caught using gillnet with mesh sizes varying from 1 to 2 inches. The fish samples ranged from 30-138mm in length and 0.41-35.83 g in weight. The length-weight relationship was W= 1.51 10-4 L2.388 and the condition factors of fish varied from 1.1 ± 0.22 to 2.03 ± 2.29. These results indicate that the growth pattern of toothpony (Gazza minuta Bloch 1795) in Pabean Bay was allometric negative.
