LENGTH WEIGHT CORRELATION AND BIOLOGICAL ASPECTS OF JERBUNG SHRIMP (Fenneropenaeus Merguiensis) IN EAST LAMPUNG WATERS

This research aims to determine the presence of biological aspects and distribution of banana shrimp in East Lampung by calculating a number of research parameters including lengthweight correlation, gonad maturity level, sex ratio, condition factor, catch percentage, size structure, catch size, and physical and chemical parameters of water.For four weeks in May 2023, research sampling was conducted randomly from fishermen's catches at the Maringgai Hygienic TPI in East Lampung, using an exploratory descriptive approach.Based on the results of the research, banana shrimp caught in May had the largest percentage (31%) in the third week, while the first week had the lowest percentage (19%).Captured male banana shrimp ranged in length from 145 to 173 mm, while female banana shrimp ranged in length from 157 to 180 mm.Banana shrimp had a catch size of 51.1 mm.Banana shrimp have a negative allometric correlation based on length-weight analysis.In addition, the shrimp obtained had a condition factor value of 1.01.In the observation of level gonad maturity, only female banana shrimp were observed to have matured gonads, and the sex ratio of shrimp was 62% : 38% or 1: 0.61 which means unbalanced.In addition, there are supporting characteristics such as temperature ranging from 30.0 to 30.6C, pH around 7.49 to 7.55 and salinity between 31.3 to 33.0 ppt.
