Abstract or Summary
  • The shrimp culture industry has been progressing steadily in many countries during the past decade due to its potential economic value. beside the progress of culture, considerable research finding was implemented to formulate diets, whereas, studies on the contribution of natural diets to shrimp growth in earthen ponds are still scarce. Therefore, this led to initiation to investigate the food and food selection preference of different stages of Penaeus monodon (PL₁₅ to adult) in tropical ponds. Study found that post larvae (9.5-22.0 mm length) and juveniles (52.0-71.0 mm length) foregut contains detritus (unidentified materials) followed by diatoms (Pleurosigms sp, Navicula sp, Nitzchia sp, Cosinodiscus sp) crustacea and insecta. Sub adult (75.0-102.0 mm length) and adult (91.0-162.0 mm length) shrimp feed on detritus, crustacea, mollusca, annelida, rotifera, insecta and phytoplankton. The food selection preference of P. monodon depends on the availability of food items in the pond bottom; however, there is indication to prefer natural food when available. The benthic organisms declined at the end of culture period. At this stage it is too early to conclude that declining of benthic organisms was due to grazing by shrimp or deterioration of pond bottom. Shrimps are deterivorus when benthic organisms are scarce since it consists of cellulose, lignin, protein, starch, fats, waxes and oils.
