The Threat of the Extinction of Kurisi Fish in TPI Gabion Belawan: Negative Growth and Excessive Exploitation

Introduction

The Gabion Belawan Fish Landing Place (TPI), located in the Belawan Sea Fisheries Port, North Sumatra, is one of the major fish landing centers for the curtain fish (Nemipterus japonicus). Kurisi fish, a member of the Nemipteridae family, has a high economic value and is the main target of fishermen in the region. However, the high and continuous intensity of fishing has raised concerns about the decline in the population of kurition fish in the surrounding waters. This article discusses the growth and rate of exploitation of kurisi fish landed in TPI Gabion Belawan, North Sumatra Province, and the potential threats to the sustainability of the fish population.

The Growth Pattern of Kurisi Fish in TPI Gabion Belawan

Research conducted at TPI Gabion Belawan showed a negative growth pattern in kurition fish landed there. This means that the growth of fish length is more dominant than heavy growth, indicating that Kurisi fish at TPI Gabion Belawan did not get enough nutrition to grow optimally. Negative growth can have a significant impact on the quality of fish and its economic value. Fish with negative growth tend to have fewer meat and lower quality, so the price is cheaper. This can have a negative impact on the livelihoods of fishermen and the economy of the community around TPI.

The Rate of Exploitation of Kurisi Fish in TPI Gabion Belawan

The results of the study also showed that the exploitation rate of kurition fish (nemipterus japonicus) in TPI Gabion Belawan had an average value of 0.81. This value indicates the "overfishing" exploitation status or excessive capture. This is because the length of the fish caught (LC) is smaller than the length of the ripe fish gonad (LM). That is, Kurisi fish are caught before reaching the gonads ripe age, so they cannot reproduce optimally and the population of Kurisi fish is increasingly threatened.

The Impact of Negative Growth and Overfishing on Kurisi Fish

Negative growth and excessive exploitation of Kurisi fish threaten the sustainability of the population and marine ecosystems around TPI Gabion Belawan. The decline in the population of kurition fish can cause an imbalance of ecosystems, and has an impact on the livelihoods of fishermen and the economy of the community around TPI. It is essential to take immediate action to prevent the extinction of Kurisi fish and maintain the balance of marine ecosystems.

Solution to Prevent the Extinction of Kurisi Fish

Several solutions can be implemented to prevent the extinction of Kurisi fish and maintain the balance of marine ecosystems:

  • Applying a Sustainable Fisheries Management Policy: Implementation of policies governing fishing quotas, minimum size of fish that can be caught, and fishing periods, become very important to protect the kurition fish population.
  • Increasing Public Awareness: Increasing public awareness and fishermen about the importance of preserving marine resources and sustainable fishing practices.
  • Fish Cultivation Program Kurisi: Development of Kurisan Fish Cultivation Program can help reduce fishing pressure on the population of fish in the wild and increase the availability of curly fish in the market.

Conclusion

Negative growth and high exploitation level in Kurisi fish in TPI Gabion Belawan showed a serious threat to the sustainability of the fish population. Steps for sustainable fisheries management and public awareness of the importance of maintaining sea sustainability are very important to prevent the extinction of kurition fish and maintain the balance of marine ecosystems. It is essential to take immediate action to prevent the extinction of Kurisi fish and maintain the balance of marine ecosystems.

Recommendation

Based on the findings of this study, it is recommended that the government and relevant stakeholders take immediate action to prevent the extinction of Kurisi fish and maintain the balance of marine ecosystems. This can be achieved by implementing sustainable fisheries management policies, increasing public awareness, and developing fish cultivation programs. Additionally, research should be conducted to identify the causes of negative growth and excessive exploitation of Kurisi fish, and to develop strategies to address these issues.

Future Research Directions

Future research should focus on identifying the causes of negative growth and excessive exploitation of Kurisi fish, and to develop strategies to address these issues. Additionally, research should be conducted to evaluate the effectiveness of sustainable fisheries management policies and fish cultivation programs in preventing the extinction of Kurisi fish and maintaining the balance of marine ecosystems.

Limitations of the Study

This study has several limitations. Firstly, the study was conducted in a single location, TPI Gabion Belawan, and may not be representative of the entire region. Secondly, the study only focused on the growth and rate of exploitation of kurition fish, and did not consider other factors that may affect the sustainability of the fish population. Finally, the study did not consider the impact of climate change on the sustainability of the fish population.

Conclusion

In conclusion, the growth and rate of exploitation of kurisi fish landed in TPI Gabion Belawan, North Sumatra Province, showed a serious threat to the sustainability of the fish population. Negative growth and excessive exploitation of Kurisi fish threaten the sustainability of the population and marine ecosystems around TPI Gabion Belawan. It is essential to take immediate action to prevent the extinction of Kurisi fish and maintain the balance of marine ecosystems.
