On the production and nutritive value of fish meal from Silver belly (Leiognathus spp.) landings at Rameswaram
1966
Srinivasan, R,
Silver belly (Leiognathus Spp.) forms a major fishery in recent years in the Rameswaram island but fetches for the fishermen very low prices ranging from Rs. 0.03 to 0.12/Kg only, there being practically no demand for the fish. The possibilities of utilizing this cheap fish are discussed and the processing method described. During the glut season the cost of production of Silver belly fish meal works out to competitive prices of Rs. 500 to 700/ton. The silver belly fish meal is of high quality with good protein content averaging 57.71% in commercial samples and 61.90% in laboratory samples and with a high pepsin digestibility of 90.0% to 92.5%. The essential amino acid composition of the Silver belly fish meal compares very favorably with other round fish meals, with high contents of lysine, leucine, arginine, isoleucine, methionine, phenyl alanine, threonine and valine. Since there is good demand for fish meal as poultry and cattle food both in the internal and external markets, there is good scope for large scale production and sale of fish meal.
