Introduction

The Yellow Selar Fish (Selaroides leptolepis) is a pelagic fish species characterized by a yellow line extending from its eyes to the base of its tail. It is one of the many fish species that are often landed at the Labu Beach Fish Landing Site (TPI) in Deli Serdang Regency, North Sumatra Province. The research conducted in September to November 2022 aimed to uncover the aspects of bioeconomic and the status of the use of yellow fish in Deli Serdang waters. This study is crucial in understanding the potential and threats of the yellow selar fish population and providing recommendations for sustainable utilization.

Understanding Potential and Pressure

The Schaefer model was used to calculate the maximum sustainable catches (MSY), maximum economic catch (MEY), and optimum efforts (OA) for yellow fish. The results showed that the optimum business is at 4,827 trips, with the optimum catches reaching 3,744,600 tons and optimum economic profits reaching Rp190,971,375. This data provides valuable insights into the potential of the yellow selar fish population and the economic benefits of sustainable fishing practices.

However, the data also shows that the use of yellow selar fish is fluctuating: 71% in 2020, 142% in 2021, and dropped to 77% in 2022. The increase in utilization rates in 2021 showed signs of overfishing, which needed to be aware of. This fluctuation in utilization rates highlights the need for a more directed strategy to maintain the sustainability of the yellow selar fish population.

Sustainable Utilization Strategy

This analysis provides an important picture of the status of the use of yellow fish in Deli Serdang waters. The decline in the level of utilization in 2022, although it is still above the optimum level, shows an effort to control arrests. However, it needs a more directed strategy to maintain the sustainability of the yellow selar fish population.

Here are some recommendations that can be considered:

Application of Catch Quota

Establishing a catch quota based on optimum catch (3,744,600 tons) can help maintain the stability of the yellow selar fish population and avoid overfishing. This approach can ensure that the fish population is not over-exploited and that the ecosystem is maintained.

Increasing the Selectivity of Fishing Gear

The use of a more selective fishing gear, such as a net with the appropriate net size, can reduce fishing that is immature and maintaining fish population. This approach can help reduce the bycatch of non-target species and protect the yellow selar fish population.

Cultivation Development

The development of yellow selar fish cultivation can help reduce fishing pressure in nature and provide alternative sources of protein for the community. This approach can help reduce the demand for wild-caught fish and promote sustainable fishing practices.

Increasing Education and Awareness

Increasing fishermen's education and awareness about the importance of preserving marine resources through training and counseling programs can encourage the application of sustainable fishing practices. This approach can help promote a culture of sustainability and reduce the pressure on the yellow selar fish population.

Conclusion

Utilization of yellow selar fish in a sustainable manner is very important to ensure the sustainability of marine resources and the welfare of fishermen on Labu Beach. By implementing the right strategy, we can maintain the population of yellow selar fish and use it optimally for future generations. The recommendations provided in this study can help promote sustainable fishing practices and ensure the long-term sustainability of the yellow selar fish population.

Recommendations for Future Research

Future research should focus on:

Conducting a more detailed analysis of the yellow selar fish population and its ecosystem
Developing a more comprehensive strategy for sustainable utilization of yellow selar fish
Conducting training and counseling programs for fishermen to promote sustainable fishing practices
Establishing a catch quota system to maintain the stability of the yellow selar fish population

By implementing these recommendations, we can ensure the long-term sustainability of the yellow selar fish population and promote a culture of sustainability in the fishing industry.
