Abstract
The analysis of biochemical constituents
during different maturity stages of P. pelagicus
showed changes in the accumulation of
organic reserves in the ovary, hepatopancreas
and haemolymph. Considerable reduction
was noticed in the moisture content, which
could be due to the continuous deposition of
organic matter in hepatic and ovarian tissuesduring maturation. The increase of the
biochemical constituents in the haemolymph
with the progress of vitellogenesis, indicates
its role as a carrier of nutrients between
different tissues. The mobilization of protein
from the hepatopancreas to the ovary during
maturation was demonstrated by a steady
decrease of the same in the hepatopancreas.
There was a gradual increase of protein in the
ovary which reached the maximum at the
mature stage
