Explores the Season Pattern and Efficiency of Bloating Fishing at the Belawan Ocean Fisheries Port

The Belawan Ocean Fisheries Port, located in North Sumatra, is a significant hub for fishing activities, particularly for mackerel (Rastrelliger sp.). However, fishermen at the port have been facing a pressing challenge in catching mackerel, with unstable catch results raising concerns about the sustainability of the future of mackerel stocks. To better understand the dynamics of catching and identify the pattern of the capture season, this study analyzed catching data and efforts to catch mackerel in the Port of Belawan.

Understanding the Dynamics of Catching

The results of this study showed significant fluctuations in catch per unit effort (CPUE) during the observation period. The highest CPUE was recorded in 2020 with a value of 1.82 tons per trip, while the lowest CPUE occurred in 2019 with a value of 0.70 tons per trip. This fluctuation indicates the factors that influence the success of catching, such as weather conditions, the presence of fish stocks, and catching practices. The analysis of CPUE fluctuations is crucial in understanding the dynamics of catching and identifying the factors that affect the success of fishing activities.

Seasonal Pattern Analysis

Seasonal pattern analysis shows that the peak of the bloated fishing season occurs in May, June, July, October, and November. The highest peak was recorded in July (the east season) with index of monthly percentage (IMP) of 134.2%. Conversely, the lowest season occurs in January (western season) with an IMP of 61.5%. The pattern of this season is closely related to the dynamics of currents and movement of sea water. Strong Eastern Season current brings nutrition and plankton to Belawan waters, creating ideal conditions for growth and breeding of mackerel. Conversely, the currents of the western season, which are weaker and tend to carry cold water, can inhibit the growth of mackerel.

The Importance of Seasonal Patterns and CPUE Fluctuations

Knowledge of seasonal patterns and CPUE fluctuations is very important for fishermen and fisheries managers. This information can be used to determine more effective capture strategies, determine the optimal capture period, and manage mackerel stocks to remain sustainable. By understanding the dynamics of catching and the pattern of the capture season, fishermen and fisheries managers can make informed decisions to ensure the sustainability of mackerel stocks and the welfare of fishermen.

Future Research Directions

In addition to the findings of this study, further research is needed to identify specific factors that affect CPUE fluctuations, such as climate change, marine pollution, and non-sustainable capture practices. With a deeper understanding of these factors, appropriate conservation and management steps can be applied to maintain the sustainability of bloated fish and the welfare of fishermen in the Belawan Ocean Fisheries Port.

Conclusion

The analysis of catch per capture and pattern of tackling seasoning and patterns of Rastrelliger sp. has provided valuable insights into the dynamics of catching and the pattern of the capture season. The findings of this study highlight the importance of understanding seasonal patterns and CPUE fluctuations in ensuring the sustainability of mackerel stocks and the welfare of fishermen. Further research is needed to identify specific factors that affect CPUE fluctuations and to develop effective conservation and management strategies to maintain the sustainability of bloated fish and the welfare of fishermen in the Belawan Ocean Fisheries Port.

Recommendations

Based on the findings of this study, the following recommendations are made:

Develop effective capture strategies: Fishermen and fisheries managers should develop effective capture strategies that take into account the seasonal patterns and CPUE fluctuations.
Determine the optimal capture period: Fishermen and fisheries managers should determine the optimal capture period based on the seasonal patterns and CPUE fluctuations.
Manage mackerel stocks sustainably: Fishermen and fisheries managers should manage mackerel stocks sustainably to ensure the long-term sustainability of the fishery.
Conduct further research: Further research is needed to identify specific factors that affect CPUE fluctuations and to develop effective conservation and management strategies.

Limitations of the Study

This study has several limitations that should be noted. The study was conducted over a limited period, and the data collected may not be representative of the entire fishing season. Additionally, the study did not account for other factors that may affect CPUE fluctuations, such as climate change and marine pollution. Further research is needed to address these limitations and to provide a more comprehensive understanding of the dynamics of catching and the pattern of the capture season.

Future Directions

The findings of this study have several implications for future research directions. Further research is needed to identify specific factors that affect CPUE fluctuations, such as climate change, marine pollution, and non-sustainable capture practices. Additionally, research is needed to develop effective conservation and management strategies to maintain the sustainability of bloated fish and the welfare of fishermen in the Belawan Ocean Fisheries Port.
