In the present investigation an attempt has been made
to know the biochemical composition of matured eggs of P. pelagicus.
The protein content was found to be 57.00% followed by lipid (14%) and
carbohydrate (6.40%). The total values of saturated fatty acids in crab
eggs were calculated as 12.78%. Among various saturated fatty acids recorded,
the amount of myristic acid (06.36%) was predominant and minimum was capric
acid (00.14%). The total amount of monounsaturated fatty acids in the
present study was found to be 02.97%. Higher amount of monounsaturated
fatty acid was nervonic acid (02.44%) and less amount of fatty acid was
palmitoleic acid (00.10%). The total amount of polyunsaturated fatty acids
in the present observation was calculated as 12.66%. Maximum amount of
fatty acid was reported to be arachidonic acid (07.77%) followed by linoleum
acid (01.83%) and minimum was linlelaidic acid (00.02%). From the present
study, it is confirmed that the percentage of protein is highest among
the biochemical constituents. The percentages of saturated and polyunsaturated
fatty acids are high when compared to monounsaturated fatty acids studied
in the matured eggs of P. pelagicus. Further study is needed to
know which biochemical constituents and fatty acids are fairly utilized
during embryogenesis and larval development. For this investigation one
should study the biochemical changes of different stages of embryogenesis
and larval development.
