Organic acids and their salts could be utilized as acidifiers to improve the performance, wellbeing and resistance status of aquatic living beings. Fishes have low degrees of acidic secretions in the gut as compared to warm blooded creatures. Incorporation of natural acids in their feed decreases pH in the gut and improves the phytate hydrolysis, diminishes the pace of gastric exhausting and improves mineralization and supplement ingestion. Current study was conducted to evaluate the effects of dietary taurine addition in linseed meal based diet on growth performance, nutrient digestibility and mineral retention of Common carp (Cyprinus carpio) fingerlings. C. carpio fingerlings were fed with graded levels (0, 2, 4, 6, 8 and 10gkg-1) of dietary taurine for 60 days. The diets were fed to triplicate groups of fish fingerlings (6.22 g average initial body weight) to apparent satiation twice a day and feces were collected. Fish performance was significantly improved (P<0.05) by dietary taurine up to optimal level of 4gkg-1 after which a noticeable decline in fish growth was observed due to poor retention of various essential nutrients and minerals. Highest digestibility values of crude proteins (73%), crude fat (66%) and gross energy (72%) were observed at this optimum inclusion of dietary taurine in linseed meal based diet. Likewise better absorption (P<0.05) of majority of minerals (Ca, Cu, Na, P and K) were found in fish fed at 4gkg-1 taurine level. Highest survival (98%) rate was recorded with fish fed on 4 gkg-1 taurine supplemented diet. So it seems that taurine could be used as feed additive in linseed meal based diet to confer better growth and health of common carp at the level of 4 gkg-1 in linseed meal based diet.
