Abstract

The fishing gear used by fishermen in catching mantis shrimp is a gillnet. The purpose of the study was to determine the elasticity of mesh size and net length to the production of mantis shrimp catch. The gillnet used in this study has a mesh size of 3.5 inches and 4 inches and a net length of 900 m, 1050 m and 1200 m. The method used in this study is a survey, and the data analysis used is the Cobb Douglas production function using SPSS version 26 and subsequently in the elasticity analysis. The results of the descriptive study both in number and composition show that the production of mantis shrimp catch based on mesh size in Kuala Tungkal waters is the most using a size of 4 inches, which is as many as 480 fish or 50.57%, while based on the length of the net, the most is using a size of 1,200 m, which is 419 fish or 45.15%. Simultaneous analysis of the signification obtained was 0.00 < 0.05, meaning that the mesh size and net length together had a significant influence on the production of mantis shrimp catch, while partially the significance value for the mesh size was 0.00 < 0.05 and the net length also had a significance of 0.00 < 0.05 which means that the mesh size and net length had an effect on the production of mantis shrimp catch. Based on the elasticity analysis, the value of the parameter coefficient of the cobb douglas regression equation is 1.229 or greater than 1, which means that the production of mantis shrimp catch is included in the category of increasing return to scale or the change in output obtained will be greater than the input used

Abstract

This study aims to compare the fishing performance of wire traps (bubu kawat) using two different types of bait, namely oil palm fruit and coconut pulp, in Kelari Lake, Muaro Jambi. The research was conducted over a period of 20 days with two treatments and a total of 20 repetitions. Each treatment used 10 units of wire traps placed randomly at the study site. The observed parameters included fish species, number and weight of catches, and frequency of fish occurrence. The results showed that seven fish species were captured during the study, namely Nilem (Osteochilus vittatus), Kapiat (Puntioplites falcifer), Sebarau (Hampala ampalong), Tembakang (Helostoma temminckii), Gabus (Channa striata), Sepat (Trichopodus pectoralis), and Baung (Hemibagrus nemurus). Nilem was the most frequently caught species in both bait treatments, while Gabus had the lowest catch frequency. Statistically, there was no significant difference (P>0.05) in the number and weight of catches between the two bait types, although coconut pulp produced slightly higher catch numbers. Environmental parameters such as temperature, pH, and water depth were within the optimal range for freshwater fish, supporting the fishing activity. This study concludes that both bait types can be effectively used with wire traps, but oil palm fruit provides more consistent results for fishermen in Kelari Lake.
