Sustainable Shrimp Farming: Estimations of a survival function
Survival rates of farmed shrimp depend on a number of factors such as water quality, stocking densities and feed stock. Inappropriate management can induce stress, disease and, ultimately, death in shrimp. This article systematically describes these relationships and develops a reduced form equation, estimated using data from a farm survey carried out in 8 provinces in Thailand, to determine shrimp survival. The results indicate that the Thai shrimp sector is presently operating at a sub optimal level and there is scope for improvement.
