Abstract
Squid (Loligo chinensis) played an important role in small scale fisheries in Banyuasin Coastal Waters, however, the information and publications were limited. This study aimed to estimate the length at first capture (LC50%), the length at first maturity (Lm), growth pattern and condition factor of L. chinensis from Banyuasin Coastal Waters of South Sumatra. The squids were observed for samples in April 2018 and March 2019 using a stationary lift net. During the observation, the squid measurement was conducted on 1179 individuals. The mantle length ranged was 40-210 mm and their body weight ranged was 2-42 gr. The value of LC50%, Lm and ½L∞ were obtained at 103 mm, 147 mm, and 110.5 mm respectively. The analysis results of the length-weight relationship (W = 0.0145L1.4618, R2 = 0.9265 and P < 0.05) showed that their growth pattern was negative allometric (b < 3). The mean relative condition factor (Kn = 1.01) above the critical value limits (K=0.56) confirmed that the environmental condition of Banyuasin Coastal Waters suitable for the L. chinensis growth. However, should be careful with their length size of the squid catch were not feasible in the capture.
