Abstract

Mukomuko Regency is one of Bengkulu Province's regencies with abundant marine resources. It has a fishing port, one of which is the Ipuh sub-district fishing port and the Teramangjaya sub-district fishing port. This study aimed to determine the size, length, weight, and composition of shark species landed at the Mukomuko Regency fishing port to identify the types of sharks that are protected based on the IUCN conservation status and the suitability of shark catches. The survey method was used to visit the research location at the ship's landing port, measure the length and weight of the sharks, and take pictures of them. The results of the sharks obtained were two species of sharks, namely the kejen shark (Loxodon Macrorhinus) with a status of almost threatened NT, 35 were found, and the Hammerhead Shark (Sphyrna lewini) with a status of very threatened CR, 15 were found. Of all the types of sharks caught, they were still juveniles and not yet suitable for catch.

Abstract

The amount of energy drained on fishermen when catching and using traditional squid fishing gear takes a long time, affecting fishermen's income. This research aims to design a semi-automatic squid fishing rod and determine the efficiency of using the new design of semi-automatic squid fishing gear. This research was conducted in the South Wangi-Wangi District, Wakatobi Regency, Southeast Sulawesi Province, from December 2023 to January 2024. The research method used was experimental fishing, which was used to design a semi-automatic fishing rod to know the effect of using semi-automatic fishing gear on catches. The construction of the semi-automatic squid fishing rod is by the planned design and is technically feasible to use. The productivity of the research shows that from the weight of the semi-automatic squid fishing rod catch of 36.02 kg, the number of 459 tails during 16 trips. The catch of traditional squid long line with a total weight of 34.76 kg and 511 tails during 16 trips. The results of statistical tests using t-test analysis show a difference that does not significantly affect the results of both fishing gears.
