Analysis of the nutritive composition of wild and farmed tiger shrimp Penaeus monodon fabricius

Abstract

The present study was undertaken to estimate and compare the nutritive value (moisture, protein, fat, carbohydrate, calcium, phosphorus, iron) of peeled tails of wild and farmed shrimp Penaeus monodon as there is a misnomer that farmed shrimp has high fat/cholesterol content compare to wild shrimp and also wild shrimp is highly nutritious than farmed tiger shrimp. The percentage moisture content in the peeled tails of tiger shrimp specimens collected from coastal waters varied from 73% to 76.74% with an average of 74.83 %, protein content ranged between 19.5% and 21.0% with an average of 20.17%. The fat content varied from 3.2% to 5.0% with an average to 4.06%, carbohydrate content ranged between 0.07% and 1.09% with an average of to 0.64% and ash content varied between 0.43% and 0.55% with an average of 0.49 %. The phosphorus (as phosphate) content ranged from 923 to 1407 and averaged 1272 mg/l00g. The iron (ppm) concentration fluctuated between 79.61 and 93.19 and averaged to 89.04 ppm. From Brackish waters the percentage of moisture content ranged from 73.84 % to 76.14 % and averaged to 75.36%, percentage protein content varied from 18.1% to 20.1% and averaged to 19.05%. The percentage fat content varied from 3.09% to 5.44% and averaged to 4.06%, percentage carbohydrate content varied from 0.29% to 1.79% and averaged to 0.94% and ash content fluctuated from 0.45% to 2.74% and averaged to 1.01%. The phosphorus content ranged between 747 and 1025 and averaged to 888 mg/l00g and calcium content ranged between 186 and 501 and averaged to 375 mg/l00g. Iron concentration varied between 82.01 and 112.06 ppm and averaged to 100.45 mg/l00g.
