This paper reports on three years of activities of a technology development-cumdemonstration project on integrated farming of brackishwater shrimp and fish-cumrice, carried out both sequentially and concurrently, at Satkhira, Khulna district, in the south west of Bangladesh. The project improved on traditional culture practices of the region and also evolved new technologies, which if adopted would benefit the farmer by increasing his yield and the quality of his product. The project also suggested that, given appropriate modifications of culture practices and of certain environmental conditions, brackish water shrimp and fish-cum-rice culture is technically feasible. The experiments were carried out in collaboration with the Directorate of Fisheries, Government of Bangladesh. Dr. A.N. Ghosh, BOBP Shrimp Culture Consultant, was associated with the project from 1982 to July 1984: he supervised the construction of the farm complex and provided technical guidance during the first one-and-a-half years of the culture operation (January 1983 - July 1984). The 1985 culture operations were designed by Dr. Mahmudul Karim, BOBP Aquaculturist, who left the project by end-March 1985. A study on shrimp seed collection was conducted by Mr. K. Larsson under a Swedish fellowship programme. Mr. Abul Kashem, Project Officer, BOBP was responsible for day-today supervision of the construction work and culture activities. The scientific officers involved at various stages of the implementation of the project were Mr. Go!am Kibria, Mr. Habibur Rahman Khandker, Mr. Rezaul Kari, Mr. S.M. Jahangir Hossain and Mr. Noor Mohammad. Mr. Ataur Rahim and later Mr. A.H.A. Jalil, Deputy Director of Fisheries, Khulna Division, acted as Technical Liaison Officers to the project. |
