Abstract:

A study was conducted between January and April 2002 with a detailed farm survey to describe the coastal shrimp farming practices and management among the different categories of farm ownership (individual, group and outside) in southwestern Bangladesh. The current farming practice was characterized by extensive culture systems with low input use, leading to low productivity levels. The different farm management practices were noticed among the different categories of farm ownership. The average farm size varied among individual (2.28 ha), group (4.59 ha), and outside lessee (19.56 ha). The production systems include multistock and multiharvest throughout the year. Inputs provided into the pond with an average depth of 0.7 m water were mainly limited to improper ratio of lime, cow-dung and fertilizer. All the categories maintained an average stocking density of 1.7 fry•m-2 for Penaeus monodon. The outside lessee stocked less quantity and achieved higher survival rate than the other two categories. Due to disease prone each category achieved variable yield. The individual and group farmers preferred other shrimp and finfish in the shrimp farming systems to increase biomass and to avert the risk of diseases while the outside lessee concentrated on P. monodon culture. Poor disease control mechanism prevailed in the area.
