Abstract

The waters of Bara Bay as one of the small pelagic fishing areas in Buru Regency have considerable potential. Fishing efforts carried out by small fishermen using traditional fishing gear such as gill nets and long line have changed along with the development of fishing technology so that studies are needed related to standing stock and the dynamics of fish resource populations. This study aims to determine the growth and frequency distribution patterns of Layang fish (Decapterus sp) and to compare body lengths of fish caught outside the bay and in the bay of Bara. The result study showed that the highest frequency distribution of Layang (Decapterus sp) fish was outside the bay at 208-218 mm, and the location in the bay was 168-179 mm in length. The growth pattern of Layang fish (Decapterus sp) at both catchment locations (Outside Bay and in the bay) is negative allometric meaning that the length growth is faster than the weight growth.The relationship between fish length and weight was very strong with value R = 0.995 at the Outside Bay catchment area and an R = 0.983 value at the Inside Bay catchment location. There is a difference in the length of the Layang fish (Decapterus sp) caught outside the bay and inside the bay with a significant value of p<0.05 where the average length of the Layang fish (Decapterus sp) outside the Bay is greater (215.876 mm) than the average length of Layang fish (Decapterus sp) in the inside Bay (193.661 mm).

Abstract

Tuna is a valuable international commodity, but its population in North Maluku is facing a significant decline due to unsustainable fishing practices and overexploitation. Conservation efforts are crucial, and the role of local communities is indispensable, as they possess traditional knowledge and experience vital for sustainability. Approximately 70% of the coastal population in North Maluku depends on the fisheries sector, making them key economic actors and guardians of the ecosystem. Various initiatives, such as the Community-Based Fisheries Management (CBFM) program, aim to empower local communities in resource management and supervision, leading to increased conservation awareness and reduced harmful fishing practices. Education and training on sustainable techniques are also essential for active contribution to conservation. However, the conservation efforts face several challenges, including illegal, unreported, and unregulated (IUU) fishing, which significantly damages tuna populations. Additionally, conflicts of interest with large commercial fishing companies and the impacts of climate change threaten local livelihoods and the marine ecosystem. Local wisdom, such as the traditional "sasi" system (temporary closure of fishing areas), proves effective in allowing fish stocks to recover. The collective management of marine resources, through the formation of fishermen groups, enhances the monitoring and enforcement of regulations. Ultimately, a collaborative approach involving the government, NGOs, and local communities is necessary to create effective and sustainable solutions for tuna conservation in North Maluku.
