Thesis Title: Detection and Quantification of microplastics in shrimp (Penaeus monodon) from local aquaculture ponds in Assasuni, Satkhira, Bangladesh

Overview: Microplastics (MPs) have emerged as significant environmental pollutants, attracting growing scientific attention in recent years. In aquatic ecosystems, MPs pose a threat to marine life due to their similarity in size to natural prey, leading to accidental ingestion. This study focused on assessing the abundance, characteristics, and potential risks of MPs in black tiger shrimp (Penaeus monodon) collected from a local aquaculture pond in Assasuni upazila, Bangladesh. To evaluate MP contamination, the gills, digestive tracts, and edible tissues of these commonly consumed shrimp were analyzed. MPs were isolated using an alkali digestion method followed by density separation, and were identified through a stereomicroscope equipped with imaging capabilities. A total of 329 MP particles were found across all shrimp samples. The average MP concentration was 2.34±0.96 particles per individual in gills (21.27%), 3.63±1.35 in the gut (33.13%), and 1.00±0.39 in 5 grams of edible tissue. The dominant MP shape identified was sheet, followed by foam, microbeads, and other forms, with fibers being the most common overall. Most MPs were smaller than 0.5 mm, and transparent particles were the most frequently observed, followed by violet and red. Statistical analysis revealed significant differences (p < 0.05) in MP concentrations across gills, guts, and edible tissues, and strong correlations were found between MP counts and shrimp body weight and total length. The pollution load index ranged from 1 to 3, and the estimated daily intake (EDI) varied between 0.82 and 1.4. Consumption of MP-contaminated shrimp presents a potential exposure pathway for humans, raising food safety and public health concerns. The results highlight the need for policy development and regulatory action to address MP contamination and assess its ecological and health risks in the food chain.

Thesis Title: Assessment of Microplastic Contamination in the Sediments of Assasuni Fish Farms, Satkhira, Bangladesh: Distribution, Characterization and Risk Assessment.

Overview: Microplastics (MPs) have emerged as a global environmental concern due to their persistence, widespread distribution, and potential threats to aquatic life and human health. Bangladesh, with its growing aquaculture industry, is experiencing increasing plastic contamination in farmed environments, yet limited information exists on sediment MPs pollution in fish farming zones. This study aims to assess the concentration and distribution of MPs in the sediments of Assasuni Fish Farms which are located in the coastal district of Satkhira, near the ecologically sensitive Sundarban region.MPs were isolated from 30 surficial sediment samples collected across 6 different stations using density separation techniques, followed by identification under a stereomicroscope equipped with imaging facilities. The abundance of MPs ranged from 5 to 18 items/kg dry sediment, with an average concentration of 15.50±3.26 items/kg (p<0.05). Most MPs (95.71%) were smaller than 0.5 mm, with fibers representing the dominant type (78.53%), followed by foams (10.43%), microbeds (7.36%) and film (3.68%). The order of prevalence among MP types was fibers > foams > microbeds> films. A significant portion of MPs were filamentous (66.06%) and irregular in shape (3.51%), with 52% of the particles being colored—indicative of land-based sources.These colored MPs pose ecological risks as they may be ingested by aquatic organisms, mistaking them for food. The ecological risk assessment (PLI = 1.642) categorized the area under category-II, indicating notable pollution levels. Probable sources of MPs contamination include feed packaging, plastic nets, aquaculture gear, and local runoff. This research highlights the presence of microplastic pollution within fish farms sediments and underscores the potential ecological threats to farmed aquatic species and the broader coastal ecosystem. The findings provide a scientific basis for policymakers and stakeholders to adopt sustainable waste management practices in aquaculture zones.

Thesis Title: Study on socio-economic conditions of fishermen in three upazilas under Khagrachhari district

Overview: Enter Project/Thesis OverviewThe study examined the socioeconomic circumstances of fishermen using a variety of methodological tools, such as participatory rural appraisal (PRA) and primarily questionnaire surveys, in three Khagrachhari district upazilas (Sadar, Dighinala, and Mohalchharri) between October 2023 and May 2024. Using a random sampling technique, 120 fisherman from 10 different upazila locations were chosen and interviewed. Thirty percent of fisherman were Hindu, thirty percent were Bhuddhist, and sixty percent of fishermen were Muslims. Approximately 75% of fishermen were married. The average household had 4.34 members, 2.66 of whom were men and 1.66 of whom were women. While some of them had varying degrees of higher education, the majority had only completed their primary education. Full katcha houses were more abundant (67%), while the semi-pacca houses were few (33%) and about 29% did not used electricity. 15% of the fishermen in this research region had lands above 50 decimal places, 35% had no lands, and 50% had lands below 50 decimal places. The average amount of money they made each month was TK. 3000.00 ± 4000.00. According to the current survey showed that 49% of the fishermen obtained their loans from NGOs, 7% from family members, 24% from moneylenders, 15% from banks, and 5% from neighbors. For drinking, approximately 83% of the fisherman utilized tube-well water, 3% used well water, 6% used ring-well water, and 8% used Jhiri water or other sources.However, in order to improve their socioeconomic status and maintain a sustainable standard of living, they require additional institutional, organizational, technical, and credit support.

Thesis Title: Availability and Marketing System of Fish and Crustaceans in an Urban Fish Market: A Study on Retail Practices.

Overview: Enter Project/Thesis OverviewThe marketing system and structure significantly impact the socio-economic conditions and production systems of local communities. Hence, this study aimed to explore the diversity of fish and crustacean species and the marketing system in the urban fish market known as Alexander Fish Market in Lakshmipur. During the study, 32 fish species and 3 crustaceans were identified, representing 35 genera, 21 families, and 11 orders. The majority of species belonged to the orders Cypriniformes (family Cyprinidae) and Siluriformes (families Bagridae and Ailiidae). Among the recorded species, a total of 3 species have been reported as Endangered (EN), 3 as Vulnerable (VU), 4 as Not Listed (NL), 6 as Not Threatened (NT), and 19 as Least Concern (LC). The fish distribution chain involved intermediaries such as beparies, aratders, wholesalers, and retailers. Three types of marketing channels were identified in the study. The average marketing cost, income, and profit for retailers were BDT 97.14/ day, BDT 792.71/day, and BDT 695.57/day, respectively. Fish pricing depended mainly on market structure, species quality, size, weight, and season. The average prices per kg for different fish species were recorded as follows: Ilish (BDT 1200±17.89), Ayre (BDT 915±8.64), Bacha (BDT 847±8.24), Ghagra (BDT 816±7.94), Khorsula (BDT 830±5.63), Golda Chingri (BDT 855±8.45), Bagdha Chingri (BDT 712±7.11), Chiring (BDT 715±6.15), and Gang Tengra (BDT 725±8.25). Major challenges in fish marketing included the use of unhygienic ice, lack of financial support from the government and NGOs, and poor knowledge of fish handling and transportation. Organizational and government support, along with extension services on fish preservation, handling, icing, and curing, are crucial for enhancing fish marketing and improving fish quality.
