![]() Trace amounts of As and Cr were detected in the analyzed sample. The concentrations of heavy metals in prawn were the highest for Co and lowest for Cd. In prawn feed, the concentrations of metals were detected in the following order: Hg > Co > Pb > Cd. This study aimed to estimate the degree of contamination and assess the probable health risk in the prawn food chain. Rabiul Islam, G M Habib, Mohammad Ruzlan Waid, Jillian L Rahman, M Safiur Kabir, J Akter, S Jolly, Y NĪn assessment of the dietary risk of heavy metal exposure to humans is important since it is the main source of exposure. Heavy metal contamination of freshwater prawn (Macrobrachium rosenbergii) and prawn feed in Bangladesh: A market-based study to highlight probable health risks. Recruitment of post-larval penaeid prawns and the bait prawn fishery in the St Lucia Lake System were monitored for. Penaeid prawns in the St Lucia Lake System: Post-larval recruitment and the bait fishery. Penaeid prawns in the St Lucia Lake System: Post-larval recruitment. The highest growth rate occurred at 20Ã-10-3 salinity. The remaining part of the growth carbon was derived from organic fertilizer and natural food. orientalis growth carbon came from formulated feed at the initial culture stage (when the prawns were 0.06Â☐.01 g in wet weight), and was 62.5% when the prawns were 9.56Â☑.04 g. The prawn carbon consumption, budget, and the effects of some factors on the budget were investigated. This study deals with contribution of artificial food pellet and natural food to Chinese prawn (Penaeus orientalis) growth in a semiintensive culture pond.
