“…Berdasarkan studi tentang status mimi di sepanjang pantai Indonesia terungkap bahwa kondisi populasi mimi semakin menurun akibat aktivitas manusia, dan terjeratnya mimi oleh alat tangkap jaring insang dan trawl merupakan ancaman terbesar yang dihadapi mimi (Meilana dan Fang 2020). Ancaman ini juga diungkapkan oleh masyarakat pesisir di Banyuasin (Fauziyah et al 2023) dan Subang (Supadminingsih et al 2018). Oleh karena itu diperlukan upaya pencegahan untuk mengurangi terjeratnya mimi pada jaring insang.…”

Horseshoe crabs (HSC) are marine arthropods, which are protected in Indonesia. Understanding fishermen's perceptions of HSC's existence was very important for the decision-making of conservation planning and management. This research aimed to analyze local fishermen's perceptions toward HSC's existence and the factors influencing their perceptions. Questionnaire-based interviews were conducted with 92 fishermen from the Banyuasin coast, from August to September 2023. Data were analyzed using descriptive statistics and multinomial logistic regression. The results revealed that most fishermen knew HSC and could distinguish their species. The survey of fishing practices showed that the vast majority of respondents operate one-day fishing with only few hours at sea (53.3%), conducting day time operation (69.6%), using 5-10 GT vessels (52.2 %), and deploying fishing gear at the sea bottom (85.9%). Based on fishermen's perception scores toward HSC existence through six assessment aspects, the majority of their perceptions were in the moderate category (54%), followed by the low (28.7%) and high (16.2%) categories. In terms of the regression output, the results of the likelihood ratio test indicated that education, setting position of gear, fishing operation time, and village location were explanatory variables that significantly influenced fishermen's perceptions.

We examined catch compositions and vulnerability of target and bycatch species in two fishing gears, namely the bottom-set gillnet and collapsible crab trap, used in small-scale fisheries of Bandon Bay, Suratthani Province, Thailand. Both gears mainly target the blue swimming crab (BSC) Portunus pelagicus, and together contribute about half of Thailand’s annual BSC catch of around 2.5 thousand tonnes. Field sampling was conducted from January to November of 2018. Specimens from bottom-set gillnets and collapsible crab traps comprised 111 and 118 taxa, respectively. Of these, 26 and 27 crab species and 41 and 46 fish species were collected by gillnets and traps, respectively. The index of relative importance of BSC was higher in gillnets (48.8 ± 16.6%) than in traps (25.0 ± 15.5%), where another swimming crab (Charybdis affinis) was more common. Cluster analysis revealed that catch compositions were seasonal and differed between the two monsoonal seasons, i.e., northeast monsoon (October to February) and southwest monsoon (May to September), and the transition period (March and April). Potential impact from both fishing gears on various stocks was assessed by standard productivity and susceptibility analysis (PSA). Vulnerability scores of the BSC stock as the main target species suggested it was at moderate risk, as assessed by PSA. The impacts of both gears to stocks of the other species in Bandon Bay showed either low or moderate risk. Ten fish stocks, including two stingrays, six species of sole and two other bony fishes, were near the threshold of high risk from gillnet fishing.
