A Case Study: Visit to Coastal Aquaculture Farm

This case study explores the diverse and sustainable aquaculture practices seen at two coastal research centers. The cultivation methods of various marine species are emphasized, and the economic significance of aquaculture. Challenges in maintaining environmental and market stability are also discussed in the study. By using integrated and innovative techniques, these centers display the potential of aquaculture to improve food security, promote economic development, and aid in environmental conservation.

4. A coastal aquaculture farm is a place near the ocean where fish, shellfish, or plants like seaweed are grown for food. It's like a big underwater garden where farmers take care of the sea creatures and plants until they're ready to be harvested and eaten. Introduction 03

5. Location Location 1: Coastal Biodiversity, Marine Fisheries and Wildlife Research Centre (CVASU). Location 2: Marine Fisheries and Technology Centre Bangladesh Fisheries Research Institute (BFRI) Figure 01: Research center (CVASU) Figure 02: BFRI 05

6. Species Cultivation At CVASU we observed two species of Seaweed culture- Ulva sp. and Gracilaria edulis. Figure 03: Seaweed Culture 06

7. At Marine Fisheries and Technology Centre (BFRI), we observed- Integrated culture (Oyster, Mussel, Seaweed and Sea bass) Two tissue culture s in the lab (Seaweed, Live feed) Figure 04: Integrated culture Figure 05: Seaweed tissue culture Figure 06: Live feed tissue culture Species Cultivation (Cont’d…) 07

8. Culture Method of Seaweed Nutrient supply Water management Biosecurity maintenance Seaweed cultivation in the Research Centre (CVASU) was monoline floating method. Figure 07: Seaweed culture method 08

9. Culture Method of Oyster, Mussel, Seaweed, Seabass Oyster, Mussel, Seaweed, and Seabass cultivation in the Marine Fisheries and Technology Centre (BFRI) was an integrated culture method. Figure 08: Oyster, Mussel, Seaweed, Seabass culture method 09

10. Tissue Culture of Seaweed and Live Feed T issue culture is the cultivation of plant cells, tissues, or organs on specially formulated nutrient media. Figure 09: Tissue culture of Seaweed and Live Feed 10

14. Conclusion Visiting Cox's Bazar coastal aquaculture farms is an enriching experience that highlights the importance of responsible aquaculture management for both local economies and global food security. It provides insights into sustainable farming practices, economic contributions, and environmental impacts. 14
