The shrimp culture industry of Bangladesh
depends on catches of the wild fry of tiger shrimp. This report, based on field trials from 1990 to 1993, describes the results of cage nurseryculture trials with both tiger shrimp (Penaeus monodon) and giant freshwater prawn (Macrobrachium rosenbergii) fry. It was thought that fry-catchers would be able to increase their earnings through sales of nursed post-larvae and juveniles. The survival of nursed post-larvae in the distribution system would also be increased. However, it is unlikely that tiger shrimp fry nursing can be made profitable. On the other hand, cage culture of a combination of hatchery-reared post-larvae and wild-caught fry of the freshwater prawn would be profitable. An NGO played an important role in the subproject by implementing technical trials and organizing and supporting participating fisherfolk groups. |
