Analysis of the Status of Sustainable Utilization and Management of Flyfish (Decapterus russelli) Resources in Pasongsongan Waters, Sumenep Regency using the Walter-Hilborn Model

Flyfish (Decapterus russelli) is a small pelagic fish with a fairly high economic value. Flying fish are the fish with the highest production landed at the Pasongsongan Beach Fisheries Port, Sumenep Regency. In recent years, the production of flying fish in Pasongsongan has continued to decline, excessive fishing activities and an increase in the number of fleets are feared to interfere with the sustainability of flying fish resources. Therefore, sustainable management of flyfish resources needs to be carried out, the purpose of this study is to find out the sustainable potential of flyfish resources, to know the number of catches allowed, and to know the status of the utilization of flyfish resources in Pasongsongan waters. The methods used in this study are quantitative and qualitative methods. The analysis used is a surplus production approach using 3 models, namely the Schaefer model, the Fox model and the Walter-Hilborn model. The results of the analysis using the Walter Hilborn model are a surplus production model that is suitable for use with a maximum catch value (Ymsy) of 2,255 tons and a permissible catch (JTB) of 1,804 tons, the utilization rate of flying fish landed in PPP Pasongsongan is 87% with the utilization status in the Fully Exploited category, where in this condition illustrates that the stock of resources has been exploited by 75-100%. An increase in the number of fishing efforts is not recommended even though the number of catches can still increase because it will interfere with the sustainability of fish resources.
