Abstract

Trap fishing gear offers several advantages, including high selectivity, the ability to keep fish alive, and support for sustainable fisheries. The productivity of catches around coral reefs and fish aggregating devices (FADs) is important to study in order to evaluate fish diversity in deeper waters across biological, genetic, species, and ecological levels. Such assessments are crucial for environmental conservation and for management based on diversity and dominance indices. This study aimed to determine the productivity, diversity, and dominant species composition of trap catches in two fishing grounds (FGs): coral reef areas and FAD zones at Lhok Kuala Daya, Aceh Jaya. The research employed an experimental fishing method, conducting five fishing operations in each zone. The overall diversity index of trap catches in Lhok Kuala Daya was 1.26, indicating a moderate level of diversity. The diversity index for catches around coral reefs was 1.15, while around FADs it was 1.58. The overall dominance index value of trap catches was 2.74, with dominance values of 0.74 in coral reef areas and 2.00 in FAD zones. These results indicate a low level of species dominance and a moderately diverse fish community in both fishing zones.Keywords:ProductivityTrapcatchFishing groundKuala daya

Abstract

Mangrove ecosystems are important blue carbon sinks, particularly through long-term carbon storage in their sediments. This study examined sediment bulk density, organic carbon content, and sediment carbon stock in the mangrove ecosystem of Deah Raya Village, Banda Aceh, Indonesia, which has regenerated following the 2004 Indian Ocean tsunami. Sediment samples were collected at three depth intervals (030 cm, 3060 cm, and 60100 cm) across three stations. Organic carbon content was determined using the Loss on Ignition (LOI) method, and carbon stock was estimated based on bulk density and carbon concentration.Bulk density ranged from 0.52 to 0.93 g cm and increased with depth, reflecting greater sediment compaction and lower organic matter accumulation. Organic carbon content varied across depths and stations, with the highest value (4.77%) recorded at Station 3 at 3060 cm, likely due to fine root biomass and reduced decomposition in anoxic layers. Sediment carbon stock ranged from 14.81 to 29.20 Mg C/ha, which is lower than national and global averages for mature mangrove systems, indicating limited carbon accumulation in this recovering ecosystem. These findings highlight the influence of vegetation structure and sediment characteristics on blue carbon storage and underscore the need for continued protection to enhance future carbon sequestration capacity.Keywords:MangroveSedimentCarbonBanda Aceh
