Analysis of Cakalang Fish CPUE (Katsuwonus Pelamis) at the Port of Fisheries of the Archipelago Sibolga

Introduction

Located on the west coast of North Sumatra, Sibolga is one of the areas with high fishing activities. The skipjack fish (Katsuwonus pelamis) has become a main commodity captured using the purse seine method. This study aims to analyze the value of CPUE (catch per unit effort) and the factors that influence the production of skipjack fishing in the Sibolga Nusantara Fisheries Port (PPN). The methodology used in this study is descriptive, with a sample of 40 fishermen from a purse seine ship, which is selected through purposive sampling technique.

Methodology

The data analysis used in this study is CPUE analysis methods and multiple linear regression. The results showed that during the six-year period (2011-2016), the value of cpue fish skipjack at the Sibolga VAT experienced significant fluctuations. The average CPUE value was recorded at 199.70 kg/trip. The highest number was recorded in 2016, reaching 412.24 kg/trip, while the lowest number occurred in 2015, which was 32.70 kg/trip.

Results and Discussion

Based on the analysis of factors that affect the catch, this study found that simultaneously, the experience of fishermen, ship size, engine power, and the length of the trip had a significant effect on the production of skipjack fish. However, interestingly, the fuel amount does not show a significant effect. Among all the factors studied, the length of the trip was identified as a dominant factor that had the most powerful influence on the production of skipjack fish.

CPUE Analysis and Explanation

CPUE is one important indicator in the fisheries industry that shows the efficiency and productivity of arrest. Fluctuations of the CPUE value observed in this study can be caused by several factors, including changes in environmental conditions, the availability of fish resources, and catching techniques used by fishermen. Given the high value of CPUE in 2016, this shows an increase in the availability of skipjack fish in that year. On the other hand, a decline in the value of CPUE in 2015 can indicate challenges in the practice of arrest or maybe environmental factors that are less supportive.

Factors Affecting the Catch

Fishermen's experience factor plays an important role in determining the success of the catch. More experienced fishermen tend to have a better understanding of fish migration patterns, more effective fishing techniques, as well as the ability to take advantage of favorable weather conditions. In addition, the size of the ship and engine power also contribute to the ability of fishermen to reach a wider capture area and produce more catches. The old trip factor shows the importance of the time spent by fishermen at sea. The longer they are in the sea, the greater the chance to catch fish, as long as in good condition.

Conclusion and Recommendations

With a better understanding of CPUE and factors that affect the catch, policy makers and fisheries industry players in Sibolga can take strategic steps to improve the sustainability of fishing and improve the welfare of fishermen. Further research is needed to explore more about the dynamics of ecosystems that affect fisheries production and to develop more effective management policies.

Limitations and Future Research Directions

This study has several limitations, including the small sample size and the limited scope of the study. Future research should aim to explore more about the dynamics of ecosystems that affect fisheries production and to develop more effective management policies. Additionally, further research is needed to investigate the impact of climate change on fisheries production and to develop strategies to mitigate its effects.

Implications for Policy and Management

The findings of this study have several implications for policy and management. Firstly, the results suggest that the length of the trip is a dominant factor that affects the production of skipjack fish. This implies that policy makers and fisheries industry players should focus on improving the efficiency of fishing operations and reducing the time spent at sea. Secondly, the study highlights the importance of fishermen's experience and the need to provide training and capacity building programs to improve their skills and knowledge.

Conclusion

In conclusion, this study provides valuable insights into the CPUE and factors that affect the production of skipjack fish in the Sibolga Nusantara Fisheries Port (PPN). The findings of this study have several implications for policy and management, including the need to improve the efficiency of fishing operations, reduce the time spent at sea, and provide training and capacity building programs to improve fishermen's skills and knowledge. Further research is needed to explore more about the dynamics of ecosystems that affect fisheries production and to develop more effective management policies.
Frequently Asked Questions (FAQs) about Cakalang Fish CPUE (Katsuwonus Pelamis) at the Port of Fisheries of the Archipelago Sibolga

Q: What is CPUE and why is it important in the fisheries industry?

A: CPUE stands for Catch Per Unit Effort, which is a measure of the efficiency and productivity of fishing operations. It is an important indicator in the fisheries industry as it helps to evaluate the effectiveness of fishing practices and identify areas for improvement.

Q: What are the main factors that affect the production of skipjack fish?

A: The main factors that affect the production of skipjack fish include the experience of fishermen, ship size, engine power, and the length of the trip. These factors can influence the success of fishing operations and the amount of catch.

Q: Why is the length of the trip a dominant factor in the production of skipjack fish?

A: The length of the trip is a dominant factor in the production of skipjack fish because it affects the amount of time fishermen have to search for and catch fish. The longer the trip, the greater the chance of catching fish, as long as in good condition.

Q: What is the significance of fishermen's experience in determining the success of the catch?

A: Fishermen's experience plays an important role in determining the success of the catch. More experienced fishermen tend to have a better understanding of fish migration patterns, more effective fishing techniques, and the ability to take advantage of favorable weather conditions.

Q: How can policy makers and fisheries industry players improve the sustainability of fishing and improve the welfare of fishermen?

A: Policy makers and fisheries industry players can improve the sustainability of fishing and improve the welfare of fishermen by implementing effective management policies, providing training and capacity building programs, and promoting sustainable fishing practices.

Q: What are some of the limitations of this study?

A: Some of the limitations of this study include the small sample size and the limited scope of the study. Future research should aim to explore more about the dynamics of ecosystems that affect fisheries production and to develop more effective management policies.

Q: What are some of the implications of this study for policy and management?

A: The findings of this study have several implications for policy and management, including the need to improve the efficiency of fishing operations, reduce the time spent at sea, and provide training and capacity building programs to improve fishermen's skills and knowledge.

Q: What are some of the future research directions for this study?

A: Some of the future research directions for this study include investigating the impact of climate change on fisheries production, developing strategies to mitigate its effects, and exploring more about the dynamics of ecosystems that affect fisheries production.

Q: How can the findings of this study be applied in real-world settings?

A: The findings of this study can be applied in real-world settings by policy makers and fisheries industry players who are interested in improving the sustainability of fishing and improving the welfare of fishermen. The study provides valuable insights into the CPUE and factors that affect the production of skipjack fish, which can inform the development of effective management policies and sustainable fishing practices.
