Abstract

Gill net fishing gear is a passive fishing gear that usually blocks the swimming direction of fish, with the addition of bait as a lure is expected to increase the chances of fish that will be used as a target catch willing to enter the fishing gear. aims to analyze the composition of crab catches on different baits and analyze the size distribution of crabs. The expected benefits of this research are as one of the information materials for efficient crab fishermen about the use of chicken intestine waste bait and fly fish against crab catches with bottom gill net fishing gear related to the availability of fish bait stocks that are uncertain and quite expensive prices. This research was conducted in January - February 2022. From the results of the t-test analysis, the tcount value was obtained at 5.014 while the t-table was obtained at 2.042 with a significance value of 0.000. Because the t-count value is greater than the t-table and the significance value is smaller than the real level of 5% or 0.05, it is concluded that there is a difference in catches between the chicken intestine bait group and fly fish bait with an average catch using chicken intestine bait higher than using fly fish bait

Abstract

Portunus pelagicus is one type of crab that has a very high economic value. The high selling price of crab encourages an increase in fishing effort, where the pressure of increasing fishing effort can cause less catch per effort obtained. To maintain the sustainability of the availability of fisheries resources, improve community welfare, equality of cultivation technology, investment development, increase foreign exchange, and development of cultivation and crab (Portunus spp.), the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020 was issued to re-regulate the provisions for catching and/or releasing crab, therefore this study aims to determine the feasibility of catching crab (Portunus pelagicus) based on the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020. This study uses a quantitative method by measuring the frequency distribution of carapace width and crab weight which will then determine the frequency of each class by entering the width data of each crab based on the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020. The results showed that more than 90% of the crab catches followed the Minister of Marine Affairs and Fisheries Regulation Number 12 of 2020, namely carapace width size above 10 (ten) cm and weight above 60 (sixty) grams per tail. Although the catch of unfit crabs is less than 10%, it should be released back to nature to support the sustainability of crab.
