species (all the shrimp Species) and 87% by-catch species (non-target), 49% economic fish and 38% non-economic
species. By-catch rate was 10.82 times of shrimp catching. The average of target catching total weight, 24.61±16.17
kg and the average of by-catch total weight during this period was 143.29±41.7 kg and the average of discard weight
