Risk factor analysis: The computation of the prior probabilities from the number of fishes lost by each fish enterprise to each of the identified risk factor is presented in Table 3. A total of 12,972 fishes were lost to all the risk factors out of which 3,409 were lost to diseases and parasites alone, followed by a loss of 2,403 to feed, Excessive rain/ flood, Diseases/parasites and excessive rain/flood thus had the largest prior probabilities of occurrence
