Abstract

Identification of fish species has an important meaning when viewed from a scientific angle because the entire sequence of subsequent work depends on the results of the correct identification of a species. The purpose of this research is to analyze the types (local, national, scientific name) and types of fishing equipment operating in the Bangka Island. This research was conducted in October 2018 to April 2019 at the Bangka Island. The method was used purposive sampling. The analysis was carried out by descriptive analysis and PSR (Pressure, State, Response). The result show that there were 30 types of fishing gear that were included in seven classes that are surrounding nets, trawls, seine nets, lift nets, gillnets, traps, hooks and lines. The main fish caught from 30 types of fishing gear used are 73 species which are included in small pelagic fish, large pelagic fish and demersal fish consisting of 38 families. More than 50% of the local names of fish on Bangka Island are different from the names of national fish including Yellow Stalk Fish, in the Bangka area called the Ciu Fish (Selaroides leptolepis), local name Selar Como Fish called Hapau Fish (Atule mate), local name Tetengkek Fish is called Singkur Fish (Megalaspis cordyla), local name Kuwe Onion Trevally Fish is called Sweet Beautiful Fish (Carangoides caeruleopinnatus), Tembang Fish is the local name Tamban Fish (Sardinella gibbosa), Bloso Fish is the local name Buto Cin Fish (Saurida tumbil). Recommendations given are that stakeholders should pay attention to local name so there is no error in data collection and use of enviromentally friendly fishing gear by taking into account the selectivity of fishing gear.

Abstract

Dog conch (Strombus turturella) is one of important sources of fishery commodities with  high economic values in Bangka Belitung. The needs of Dog conch as consumption still depends on fishermen harvest since its aquaculture has not been cultured until now. This study aims at determining behavior and feeding habit of dog conch. The study was conducted in July 2014 to January 2015. The experiments passed some stages 1) samples was taken in the field by hand collecting, 2) the experiment of seagrass consumed preference, 3) feeding behavior, and 4) Analysis of the stomach contents. The results indicate dog conch does not consume seagrass immediately, but detritus and microalgae species of Thalassiosira sp., Synedra sp., Nitzschia sp., Navicula sp. Dog conch eats by put the probiosis of the shell, then it grinds sediment layer, seagrass leaves and shells of other individuals as source if food. Dog conch behavior from beginning to  ending of the observation includes several stages: 1) Initial treatment actively foraging, 2) Individuals dog conch assembled or in pairs, 3) on the second day, the dog conch hoards himself on the base of the substrate and only elastic probiosis which occasionally appear occasionally at the substrate bottom.
