Growth pattern and Condition factor of Mangrove Crab (Scylla tranquebarica) in Segara Anakan Cilacap Regency

Abstract

Scylla tranquebarica is a species of mangrove crabs belong to family Portunidae, class Crustacea. The purpose of this research was to study population mangrove crab S. tranquebarica habitat in Segara Anakan Lagoon Cilacap Regency. The mangrove crabs were collected in April 2019 using bubu trap as fishing gear. Sampling was carried out in Klace, Sapuregel and Panikel area. The growth pattern for mangrove crab in the Sapuregel area was allometric negative both for males (b= 2.27) and females (b= 2.28). But for Panikel village area, the growth pattern for males was allometric negative (b = 2.67), while for females it was allometric positive (b = 3.95). In the Panikel area, the average value for the condition factor was 1.456 ± 0.65. Additionally, in the Sapuregel area the average value of Condition factor was 1.004±0.09.
