Afsana Kabir Dipty
Committed to dynamic teaching that supports the growth of my students’ knowledge and abilities. My passion lies in exploring water quality parameters, aquatic biodiversity, and plankton communities. At present, my research examines the relationship between water quality parameters and their effects on plankton communities. This work is intended to guide future stakeholders in recognizing the importance of water quality and in identifying the parameters that most influence phytoplankton communities within aquatic systems.

Thesis Title: Fish Species Availability and Marketing Structure in Kabirhat Upazilla of Noakhali District, Bangladesh: Recommendations for Efficient Marketing.
Overview: This study examined the pricing dynamics, species availability, and fish marketing system in Kabirhat Upazila, Noakhali District, Bangladesh, over an eight-month study period, from July 2024 to February 2025. Data was gathered from four selected fish markets using structured questionnaires from 20 customers and 60 fish traders (retailers, wholesalers, and aratdars). 23 fish species and 2 crustaceans were discovered, where carps accounted the highest percentages (54.77%). According to price study, mrigal carp had the lowest retail price (BDT 155.99/kg), while hilsa shad had the highest (BDT 1294.16/kg). Nine different marketing routes were found, most of which involved multiple middlemen. These channels drastically decreased the fishermen's share of the final price, which ranged from 61.46% to 73.83%. Marketing cost ranged 0.40% to 2.34% of the retail price where icing having the highest percentage (34%) followed by transportation (27%), and other sectors. Seasonal fluctuations influenced both fish availability and prices in December and February recorded the highest and lowest volume respectively. Extended marketing chains, inadequate handling, and a lack of stakeholder training were among the main obstacles. Government fish depots, improved storage and transportation facilities, and policy interventions are suggested for a fish-based marketing system in the current study location.

Thesis Title: Diversity of fishery resources and catch efficiency of fishing gears in the Feni River (Bangladesh)
Overview: A thorough examination of fish diversity indices, gear efficiency, catch composition, and decline causes of fish diversity was carried out in the Feni River (Bangladesh). Monthly data collection took place from July to December 2023 at three stations of the river. A total of 8 fish species under 7 orders and 8 families were recorded. The order Perciformes was the most prevalent, representing 30% of the total. Approximately half of the identified species are classified as least concern, while the remaining 4 species are classified as Not Threatened (12.5%), Vulnerable (12.5%), Endangered (12.5%), and Critically Endangered (12.5%). The mean values of the Margalef’s richness (d), Pielou’s evenness (J), Simpson’s index (1-D), Shannon-Weaver diversity (H), and 0.973±0.002 were calculated as fol lows: 1.720±0.139, 0.699±0.112, and 0.248±0.034, respectively. Based on the Bray-Curtis similarity matrix, two groups were observed at a similarity of 58% within six months across the three sites. The chandi net and ghera net recorded the highest CPUE (kg gear-1day-1) at 5.93±0.966 and 0.53±0.041, respectively. The highest fish catch was recorded in July (2249 ± 668.71 kg), while the lowest was in October (1564 ± 465.05 kg). There was no significant difference (p>0.05) in the monthly fish catch. Fish biodiversity in the Feni River is declining day by day as a result of pollution, overfishing, the use of harmful gear, and a lack of optimal water and pollution. To improve and conserve fish species in the Feni River, it is strongly advised that appropriate fishery management techniques should be applied, that overfishing be closely monitored, and that fishermen be made more aware of their rights.

Thesis Title: Fishery resources diversity and fishing gear catch efficiency in the Meghna River, Bangladesh
Overview: catch composition and the causes of the loss in fish diversity data were collected for six months during July 2023 to December 2023 from the Meghna River, Bangladesh. There was a total of 6 fish species and 1 prawn species, belonging to 7 orders and 7 families and among them order Cypriniformes (21%) was identified most dominant order. The mean values of Shannon-Weaver diversity, Simpson's index, Margalef's richness, and Pielou's evenness indices were measured as 1.862±0.016, 0.976±0.001, 0.537±0.018, and 1.059±0.041, respectively. There is no significance difference (p> 0.05) was observed for the mean monthly fish catch in the present study. Numerous factors, including overexploitation, pollution, and natural causes like siltation may be responsible for a decline in biodiversity. Fish variety in Bangladesh's Meghna River can be greatly enhanced and preserved by using authorized fishing gear, enforcing fish laws and regulations effectively.

Thesis Title: Preferred food items of Juvenile hilsa (Tenualosa ilisha) of the Meghna river estuary in Moju Chowdhury Hat, Lakshmipur
Overview: Monthly and size group-wise variation of feeding preference of juvenile hilsa was studied in the Meghna estuary, Lakshmipur from July to December, 2022. The specimens were dissected and gut contents were analysed by frequency of occurrence (FOC%), volumetric analysis (V%), relative gut length (RLG) and index of relative importance (IRI%) method. Fishes (n=120) were divided into 5 different size groups i.e. below 5 g, 5-10 g, 10-15 g, 15-20 g and 20-25 g. There were 26 genera of phytoplankton and 16 genera of zooplankton were recorded. According to FOC%, V% and IRI%, copepod and diatoms were found the major food constitutes in all the five size groups. Major bacillariophyceae genera were recorded Coscinodiscus sp., Synedra sp. and Rhizosolenia sp., and followed by copepoda (Calanus sp. and Pseudodiaptomus sp.). Based on the FOC% and V% we found sand particles as a constituent in the gut of hilsa (early age) was noticed but from IRI% value, it was observed that sand was only engulfed by hilsa with food particles during bottom feeding but not a preferred food item.
