Abstract

The abundance and distribution of fish are influenced by environmental productivity, such as chlorophyll-a distribution and variations in sea surface temperature (SST). The lack of technology fishermen use in the waters of the Bali Strait has resulted in the high potential of fish resources not being optimally utilized. This study aimed to determine potential fishing zones by utilizing Aqua MODIS satellite data which can detect SST and chlorophyll-a. The image data observed was from October to December 2018 to 2020. The method used is the Single Image Edge Detection Algorithm, where this algorithm is used to determine potential fishing areas designed to detect fronts in SST images. The results showed that in December 2018, 7 potential fishing points were produced, marked with a chlorophyll-a value of 0.25 mg/m3 and an SST of 29.25°C. In December 2020, 82 potential fishing points were produced, with a chlorophyll-a value of 0.31 mg/m3 and an SPL of 29.79°C. Validation was carried out by analyzing the result of image processing with fish catch data obtained from Pengambengan PPN, Muncar PPP, and Kedonganan TPI. SST, with a value of 27°C, is the ideal temperature for fish where when the temperature increases, the number of potential fish catch points decreases and vice versa. The distribution of chlorophyll-a content with a value of > 0.2 mg/m3 affects the number of potential fishing points, where the higher the chlorophyll-a content, the more fishing ground points and vice versa.

Abstract

Illegal, unreported, and unregulated fishing happens globally, especially in Indonesian waters; one of the problems that is often faced is compliance with fishing quotas. Furthermore, as a CCSBT member nation, Indonesia must adhere to all provisions put in place for the preservation of fish resources, particularly southern bluefin tuna. One of their requirements, following the provisions on the number of catches that apply to Indonesia, is to eradicate IUU fishing and fishing quotas; this study attempts to ascertain the measures made by Indonesia to enforce compliance with the CMM’s implementation for CCSBT. Interview method and an examination of relevant papers and regulations were used in this research tuna associations and government organizations involved in the management of bluefin tuna collected in 2021, Indonesia was 99% free from over quota according to the result of alleged IUU infractions committed by one of the tuna fishing vessels in the Indian Ocean RFMO area. Indonesia is required to pay back 91.3 tons per year over the following 5 years despite breaking the rules established by international bodies in 2019–2020. After the punishment, Indonesia is being more proactive in putting various initiatives into action to ensure the sustainability of southern bluefin tuna in the future.
