This study investigated microplastic (MP) contamination in six tropical fish species of different mouth sizes and trophic levels from Saint Martin's Island, Bay of Bengal. A total of 309 microplastics (MPs) were extracted from the gastrointestinal tract (GT) of these selected fishes, where the presence of MPs was 100 %. The mean abundance of MPs was significantly varied among the species and ranged from 4.38 to 10 MPs/GT (p < 0.05). This study revealed that MP incidence was strongly correlated with the mouth-to-body ratio of the selected fishes (r = 0.424, p = 0.003) and trophic levels (r = 0.458, p = 0.002). Results suggest that fish with larger mouths are more likely to ingest MPs, intentionally or unintentionally, compared to those with smaller mouths.

This study reports on the fate of stranded plastic litter (SPL) from a marine protected area at Saint Martin’s Island, Bay of Bengal. A total of 1341 plastic litter items were collected in 2022 and 928 litter items in 2023. Among them, 916 litter items were SPL collected in 2022 and 714 litter items in 2023. The mean density of SPL was 1.08±0.52 items/m2 in 2022 and 0.75±0.14 items/m2 in 2023. One-way ANOVA showed significant differences in SPL density among the sampling sites for 2022 (F10,22 =5.446; p=0.000) but no significant difference in 2023 (F10,22 =1.135; p=0.382). Cigarette butts and plastic packets like candy, chips, food covers, and nylone ropes were the most dominant SPL items contributing 41.18 - 32.42%, 18.45-14.29%, and 9.24-13.21% of the total SPL, respectively. Our results revealed that the main sources of the SPL are tourism, fishing activities and household activities by local inhabitants.

Abstract
Seaweed farming in Bangladesh is in its early stages compared to other Southeast Asian countries. Despite having a vast coastline of 480 km and 25,000 km2 of coastal area, the potential of seaweed remains largely untapped due to low awareness. Bangladesh boasts arich variety of 133 seaweed species, with eight commercially significant species. Efforts are needed to raise awareness, improve cultivation techniques, identify suitable sites, anddevelop research-based technologies to harness the economic and ecological benefits of seaweed farming in the country.

Abstract
This study aimed to detect and analyze possible algal blooms in the northern Bay of Bengal using Fluorescence Line Height (FLH) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) from 2002 to 2022. Monthly MODIS remote sensing observations with a 4 km spatial resolution were processed and classified to explore the temporal patterns and environmental influences on Harmful Algal Blooms (HABs). The correlation between FLH and other ecological parameters was examined, revealing that sea surface temperature (SST) does not significantly influence FLH variation. In contrast, river discharge substantially impacts FLH concentration, indicating that nutrient supply during the rainy season may drive frequent algal growth. Temporal analysis highlighted that algal blooms predominantly occur from June to October, peaking in September and October, with a secondary bloom observed in January. This study demonstrates the utility of MODIS fluorescence as a screening tool to identify risk areas for potential algal blooms, particularly in regions with high river discharge. It emphasizes the need for targeted monitoring and management strategies to mitigate the impacts of HABs in the northern Bay of Bengal.
