Abstract:
Laboratory analysis conducted on the nutritional quality of the
fin fish of different standard lengths in the Unnichai tank in Batticaloa
yielded the following quantitative values. The protein content ranged
from 8.76–23.55%. The lipid content varied between 1.89–16.77% while
the element spectrum revealed that the flesh also has minerals such
as Na, Ca and K. The proximate composition varies with the standard
length of the fish. The same phenomenon has been found with different
body parts for its composition. If the fish offal have high protein, fat
suitable to the ornamental fish feed and shrimp feed preparation. This
lead to reduction in the solid waste in the market.
The standard length provides a tool for fisheries management
regulation to be placed for future sustainability of the fish stocks
(common property resource) in the tank. The results indicate that fish
of moderate size fish are economically suitable for utilization without
harming the parental brood stock. Thereby catering to the future
nutritional needs.
