An experiment was carried out to determine the effect of supplementary phosphorus on growth and faecal excretion in juveniles of Fenneropenaeus indicus. A practical feed was formulated using fish meal, squid. mantis shrimp, soyabean meal, wheat flour, fish oil and lecithin. To this feed, phosphorus was supplemented as mono sodium di- hydrogen orthophosphate at 0.0, 0.25, 0.5, 0.75 and 1.0%. Results of a 60- day feeding trial in triplicate on the juveniles of E indicus (initial average live weight 0.45 j: 0.008 g) showed that dietzry supplementation of phosphorus was essential and the best perform2.nce (310 % increase in live weight and 1.4C1 FCR) was recorded by the feed haku~g 7.50 g kg-' supplen~entary phosphorus (total phosphorus in the diet 1.83%) which was : :gnificantly higher than the control feed fed groups having 1.03% clictary phosphoms (live weight increase 224% and FCR 1.60). Additional supplementary phosphorus (more than 0.75 g/lOOg) had no beneficial effect. Shrimp fed with differe~t feeds maintained the body phosphorus level in the range of 1.23- 1.31g/100g irrespective of dietary phosphorus levels and t?lc same trend was continued in Ca : P ratio in the body. There was no significant change jn the prcxiir~ate composition of the experimental shrimps on termination of thc feeding trial. Phosphorus excretion in faeces increased with increase in dietary phosphorus Not Available |
