Bioeconomic Analysis And The Level Of Utilization Of Squid (Loligo Sp.) At The Belawan Ocean Fisheries Port

by ADMIN 108 views

Introduction

Squid is a highly valuable fisheries commodity, and its high economic value has led to a significant increase in its capture by fishermen. However, the high level of arrest can result in overfishing, which can threaten the availability of the squid population in these waters. This study aims to preserve the squid population by applying bioeconomic analysis, which is designed to ensure that the management of squid resources is not only focused on profit maximization efforts, but also considers the sustainability of these resources.

Background

The Belawan Ocean Fisheries Port (PPS) is one of the major fisheries ports in North Sumatra Province, Indonesia. The port is known for its high volume of squid catch, which is a significant source of income for fishermen. However, the high level of arrest has raised concerns about the sustainability of the squid population in these waters. Overfishing can lead to a decline in the squid population, which can have a negative impact on the ecosystem and the livelihoods of fishermen.

Methodology

This study was conducted in July to August 2019, using the production surplus method from the Schaefer and Fox model to estimate the maximum sustainable potential (Maximum Sustainable Yield, MSY) and implement the bioeconomic model of Gordon Schaefer. The study aimed to estimate the MSY value of squid in the Belawan Ocean Fisheries Port and to determine the optimal level of utilization of squid resources.

Results

The results of the study showed that the level of utilization of squid in the Belawan Ocean Fisheries Port experienced overfishing in 2017, which reached 119% of the recommended limits. The estimated MSY value of squid in the Belawan Ocean Fisheries Port was 1,382,3585 tons per year, while the recommended total Allowable Catch (TAC) value was 80% of the MSY value, which is around 1,105,8868 tons per year.

Discussion

The results of the study highlight the importance of bioeconomic analysis in the management of squid resources. The study shows that the level of utilization of squid in the Belawan Ocean Fisheries Port has exceeded the recommended limits, which can lead to overfishing and a decline in the squid population. The study recommends that the management of squid resources follows the condition of the maximum economic yield (MEY), which is the most optimal catches and benefits are obtained, while also maintaining the sustainability of fisheries resources.

Conclusion

In conclusion, the study highlights the importance of bioeconomic analysis in the management of squid resources. The study shows that the level of utilization of squid in the Belawan Ocean Fisheries Port has exceeded the recommended limits, which can lead to overfishing and a decline in the squid population. The study recommends that the management of squid resources follows the condition of the maximum economic yield (MEY), which is the most optimal catches and benefits are obtained, while also maintaining the sustainability of fisheries resources.

Recommendations

Based on the results of the study, the following recommendations are made:

  • The management of squid resources in the Belawan Ocean Fisheries Port should follow the condition of the maximum economic yield (MEY).
  • The level of utilization of squid should not exceed the estimated MSY value of 1,382,3585 tons per year.
  • The recommended total Allowable Catch (TAC) value of 80% of the MSY value, which is around 1,105,8868 tons per year, should be followed.
  • Fishermen should be involved in the decision-making process to ensure that they understand the importance of maintaining the availability of fish resources for a better future.
  • Awareness of sustainability must be instilled among fishermen to create harmonization between economic benefits and environmental sustainability.

Limitations

This study has several limitations, including:

  • The study was conducted in a single fisheries port, which may not be representative of other fisheries ports in the region.
  • The study used a single model to estimate the MSY value of squid, which may not be accurate.
  • The study did not consider other factors that may affect the sustainability of squid resources, such as climate change and habitat degradation.

Future Research

Future research should aim to:

  • Conduct a more comprehensive study of the sustainability of squid resources in the Belawan Ocean Fisheries Port.
  • Use multiple models to estimate the MSY value of squid and to determine the optimal level of utilization of squid resources.
  • Consider other factors that may affect the sustainability of squid resources, such as climate change and habitat degradation.
  • Involve fishermen in the decision-making process to ensure that they understand the importance of maintaining the availability of fish resources for a better future.

    Bioeconomic Analysis and the Level of Utilization of Squid (Loligo sp.) At the Belawan Ocean Fisheries Port: Q&A =============================================================================================

Q: What is bioeconomic analysis, and how does it relate to the management of squid resources?

A: Bioeconomic analysis is a method of analyzing the economic and biological aspects of a fishery to determine the most sustainable and profitable way to manage the resource. In the context of squid resources, bioeconomic analysis can help determine the optimal level of utilization of squid, taking into account both the economic benefits and the biological sustainability of the resource.

Q: What is the maximum sustainable yield (MSY) of squid in the Belawan Ocean Fisheries Port?

A: The estimated MSY value of squid in the Belawan Ocean Fisheries Port is 1,382,3585 tons per year.

Q: What is the recommended total allowable catch (TAC) value of squid in the Belawan Ocean Fisheries Port?

A: The recommended TAC value of squid in the Belawan Ocean Fisheries Port is 80% of the MSY value, which is around 1,105,8868 tons per year.

Q: Why is it important to follow the condition of the maximum economic yield (MEY) in the management of squid resources?

A: Following the condition of the MEY ensures that the most optimal catches and benefits are obtained, while also maintaining the sustainability of fisheries resources. This is because the MEY condition takes into account both the economic benefits and the biological sustainability of the resource.
