Abstract


This research was conducted in The Barumun River in April-June 2020, Determining 5 research sites using purposive sampling method. The purpose of this study is to find out the abundance of shrimp galah in the water of Barumun River Labuhanbatu Selatan Regency.The Total sample for the study as many as 342 individuals with the value of estimating the abundance ranged between 20-85 ind/m2.The value of the ratio of the sexes prawns found in station 2 with a number of 81 individuals, the number of individual male 18 ind/m2 and of females 30 ind/m2, and the lowest in station 3 with the number of 60 individuals, the number of individual male 24 ind/m2 and begina 18 ind/m2.from the results there can be seen that the amount of shrimp the females are larger than shrimp male. Because of Udang galah (Macrobrachium rosenbergii) males are able to fertilize shrimp females up to five tails in time almost simultaneously.The low Ratio of prawns on the station caused by the amount of people who do a lot of activity so decreasing the population of shrimp in the vicinity of the station, which can hinder the process of the reproduction of prawns.
