The Study of Yield per Recruit of Brownbanded Bambooshark (Chiloscyllium punctatum) from Songkhla, Thailand

Abstract

The brownbanded bambooshark (Chiloscyllium punctatum) is dominant benthic shark in Southeast Asia, which was caught mainly as by catch. Growth parameter as Asymptotic Length (L∞) and Curvature Parameter (K) for unseparated sex, male and female were 101.47 cm. and 0.78 year-1, 101.47 cm. and 0.78 year-1 and 98.12 cm. and 0.95 year-1, respectively. Result shown that female brownbanded bambooshark can grow faster than male. Result of yield per recruit show that population of brownbanded bambooshark caught from southern gulf of Thailand now still in a good condition (B/BMSY = 2.19 and F/FMSY = 0.44).
