Abstract: Most agro-based inorganic chemical are heavily employed today in lots of environmental remedial activities apart from their core use in agriculture. The dangers of over use of these products have necessitated toxicological investigations using bio-indicators to assess potential impacts on aquatic life. Calcium carbonate was tested on the brackish river prawn, Macrobrachium macrobrachion in a completely randomized design to determine its long term effect on the prawns. The experiment was conducted for two weeks and afterwards the body tissues were extracted and prepared on glass slides for photomicrography. The results showed that the toxicant did not negatively impact the muscles and carapace as there were no degenerations of the cells and tissues. This revealed that the agricultural lime is non-toxic to the juvenile brackish river prawns and also showed that it is safe for use in prawn culture as source of calcium for proper growth and development. Also the correlation was significant at P< 0.05 confidence level. The water quality parameters occurred at permissible ranges for prawns and the relationships between parameters did not influence destructive impact on the test organisms. It has also created an avenue for further research on this product use as nutrient supplement in prawn culture
