Abstract

Probiotics is a bacterial product that has beneficial for fish; both for growth and body's defenses from bacteria desease. The aim of the study is to determine the types of candidate of probiotic bacteria from the digestive tract of giant prawns that is found in Teratak Buluh Pekanbaru, Riau. This research was conducted at the Laboratory of Microbiology and Biotechnology of Fishery Faculty of Fisheries and Marine Sciences University of Riau, Pekanbaru to get a candidate of Probiotic Bacteria and do molecular examination that consists of purification of electrophoresis gel and DNA sequencing at the Institute for Biotechnology Serpong, Tangerang Banten. The method of this study is a survey method that used physical and biochemical test and molecular identification . The results showed that eleven isolates of bacterial are the species Bacillus BDU4 strain from A Bacteria isolates with 99 %  homology and 10 isolates of  bacterial are bacillus genus because the degree of homology below 97% and they are considered as the original indonesia’s new species probiotic bacteria.

Abstract

This study was conducted at PPN Sungailiat, Bangka Regency, to identify morphometric and meristic characteristics of Jebung fish (Abalistes stellaris), as well as environmentally friendly fishing gear. The research method used was descriptive with a simple random sampling technique to collect fish samples. Data were collected through observation and interviews, then analyzed using morphometric and meristic identification. The results showed that Jebung fish had 23 morphometric characters and 9 meristic characters, with an average total length of 30.5 cm and a standard length of 27 cm. Fin characteristics showed significant differences compared to other fish in the same family. In addition, the recommended fishing methods are bubu and bottom fishing to maintain the sustainability of the fish population. The conclusion of this study is that Jebung fish has distinctive morphometric and meristic characteristics, and requires an ecosystem-based management strategy to maintain its sustainability. The results of this study can serve as a basis for better fisheries resource management policies in the Bangka region.
