from present study indicate good development. Response
of the protein and RNA/DNA ratio to the feeding condi-
tions was signi cantly observed (Akarte et al., 2014).
Determinations of RNA and DNA can be used as bio-
chemical indicators of recent growth rates of sh within
each time period; RNA concentrations increased some-
what with higher feeding rate and faster growth. DNA
concentration, however, increased with greater weight
loss and longer periods of food deprivation. The slight
decrease in DNA with increased growth and the slight
increase in DNA with increased weight loss were prob-
ably due to changes in cytoplasmic volume. It was
observed that food deprivation, other cellular constitu-
ents are metabolized and DNA is preserved (Leslie, 1955).
In the current study, the biochemical composition of
sh eggs of Hilsa and Pangus were observed. The bio-
molecules of these eggs which were being under con-
sideration were proteins, carbohydrates, lipids, minerals,
and nucleic acids (RNA and DNA). These bimolecular
components show the status and productivity of an
organism. In this study, it was shown that the concen-
tration of protein was in the range of 27.7mg/100mg
for Pangus sh and 40.0mg/100mg tissue in Hilsa sh.
Amount of protein shows the availably of food through
productivity of water to the organism. Finding which
is at variance with a recent suggestion are free amino
acids may serve as the sole substrate for aerobic energy
metabolism during embryogenesis in species, (Fyhn
et al., 1986). So, higher values of protein quantity sug-
gest good nutritional quality of sh eggs as human food.
