Abstract

The coastal waters of Banyuasin have potential shrimp resources and the exploitation rate is still below 70%. Trammel net is the pre-eminent fishing gear of shrimp used by local fishermen. This research aimed to analyse the composition and biodiversity of trammel net catch in Banyuasin coastal waters of South Sumatera, Indonesia. An experimental fishing method was used for data collection by fishing ground following the local fishermen habit. The composition and biodiversity of trammel net cacthes were quantitified based on the weight of each caught species. The results for 11 trips produced an average catch of 8.964 kg consisting of main catch (61.76%), by-catch (14.36%) and discarded catch (23.88%). The main catch was Banana prawn (Fenneropenaeus merguiensis) with high relative abundance (RA) of 61.8% and high availability frequency of 100%. Most of the catch had an inter-trip similarity (Cs > 50%), mean value of medium diversity index (H' = 1.54), moderate evenness index (J' = 0.48) and low dominance index (D = 0.38). This condition showed that the community structure of the species caught by the trammel net was in a fairly stable state with the number of species spread fairly evenly and no species dominated each other.
