Abstract

Mangrove crabs are a type of crustacean that lives in mangrove and estuary ecosystems. one of the freshwater fishery products that have high economic value that are often caught in Lambur Luar Village using trap fishing gear. Purpose of this study was to describe the characteristics of mangrove crabs caught using traps in Lambur Luar Village, Jambi Province. This study was conducted from February 1-16, 2025. The research method used was a census, with data collection techniques using probability sampling. The data observed included the type of mangrove crab, weight, carapace length, carapace width, and sex. Differences in weight, length, and carapace width of mangrove crabs were analyzed using ANOVA followed by Duncan's test at a significance level of 5%. The results showed that there were three species of mangrove crabs caught, namely Scylla serrata, Scylla olivacea, and Scylla tranquebarica. After ANOVA test and Duncan's further test, it was found that the carapace length between Scylla serrata, Scylla olivacea, and Scylla tranquebarica was significantly different (p≤0.05). while the carapace width and weight were not significantly different (p>0.05). Variations sex ratio in the Scylla serrata species were (0.78:0.22) and Scylla tranquebarica (0.67:0.33), indicating that the male population was more dominant in these two species. While the Scylla olivacea species, the sex ratio was almost balanced, namely (0.51:0.49). The conclusion of this study is that the characteristics of mangrove crabs differ between males and females, and there are significant differences in carapace length between mangrove crab species found in Lambur Luar Village.

Abstract

Small-scale fisheries in coastal areas utilize various fishing gears, including bottom gillnet, which can catch fish species with different trophic levels. Fishing activities may influence the trophic structure of fish communities and the vulnerability of species to exploitation. This study aimed to analyze the trophic structure, vulnerability level, conservation status based on the IUCN Red List, and Mean Trophic Level (MTL) of fish species caught using bottom gillnet in the coastal waters of Lambur Luar Village, Tanjung Jabung Timur Regency. The study used a survey method with data collected through direct observation of fishermen's catches. Data analysis included catch species composition, trophic level values ​​obtained from the FishBase database, vulnerability analysis of each species, identification of IUCN conservation status, and calculation of Mean Trophic Level (MTL) based on the proportion of catch composition. The results showed that the catches consisted of 20 species, with trophic groups dominated by mesopredators (50%) and top predators (25%), while omnivores and herbivores were found in smaller proportions. Vulnerability analysis indicated that most species were categorized as having low to moderate vulnerability, although several species showed high vulnerability to fishing pressure. Based on the IUCN Red List, most species were classified as Least Concern (LC). The calculated Mean Trophic Level (MTL) was 3.2, indicating that the catches were dominated by mid-level carnivorous fish species.
