Abstract

The Kerandin River is located in North Lingga District, Lingga Regency, one of the districts in the Riau Islands Province. Geographically, Lingga Regency is situated between 0°20' N and 0°40' S and 103°30' E and 105°00' E. The residents of Kerandin Village earn their livelihood as farmers and fishermen. One of these potentials is the potential for fisheries, including both capture fisheries and aquaculture. The primary fishery commodity in Lingga Regency is the Mangrove Crab (Scylla serrata). Mangrove crabs are a fishery product with significant economic value, typically caught using pento fishing gear. Pento is a static fishing tool that requires bait to operate. People in Kerandin Village use stingrays as bait. However, one potential bait in the Kerandin River is cheap and easy to obtain but has not been used as bait, namely mullet, which will be tested as an alternative bait for catching mangrove crabs. This research used the Experimental Fishing method, and the data were analyzed using normality tests and T-tests. The research showed that the bait for belukang (Hexanematichthys sagor) produced more crab catches than the bait for stingrays (Trygon sephen). The T-test comparing these two bait types revealed a significant difference, with a value of -2.804 (df = 18) and a significance level of 0.006.

Abstract

This research was conducted in October and November 2022. The research aims to identify problems in the implementation of fisheries port functions in the Regional Fishery Port I Carocok Tarusan and to find solutions in the form of strategies that must be implemented so that the Regional Fishery Port I Carocok Tarusan can apply all fisheries port functions in accordance with Ministerial Regulation No. 08/MEN/2012. The method used is a survey method. The data collected in this research relate to the implementation of fisheries port functions under Ministerial Regulation No. 08 of 2012 at the Regional Fishery Port I Carocok Tarusan. Data analysis was carried out descriptively by examining the conformity of the functions of the Regional Fishery Port I Carocok Tarusan with Ministerial Regulation No. 08 of 2012. Furthermore, a SWOT analysis was conducted to identify strategies to implement so that these functions can be carried out at the Regional Fishery Port I Carocok Tarusan. The results of the study indicate that out of the 9 functions that have been established, only a few functions have been implemented by Regional Fishery Port I Carocok Tarusan, including the function of providing services for mooring and anchoring of fishing boats, the function of fish loading and unloading services, the function of fish marketing and distribution, the function of providing logistics and supplies for fishing vessels, the function of marine tourism, and the function of providing and/or other services in accordance with the applicable laws and regulations. The results of the SWOT analysis show that the position of Regional Fishery Port I Carocok Tarusan is in quadrant III; therefore, a turnaround W-O (Weaknesses-Opportunities) strategy is needed to minimize weaknesses and take advantage of opportunities
