Introduction
Mollusca are very important for many
reasons. Apart from their commercial
value for use as a human foodstuff and in
the feeding of several crustaceans (Ekin
and Bashan, 2010) Biochemical assays
and nutrients play a vital role in physical
growth, development, maintenance of
normal body function of physical activity
and health. The knowledge of the
biochemical composition of any organisms
is extremely important since the nutritive
value is reflected in its biochemical
contents (Periyasamy et al., 2011).
Mollusca generally contain large amounts
of lipids which, in comparison with
proteins and carbohydrates, have high
energy contents and are thus costly in
energetic terms. As lipid contents vary
between species, comparisons of
reproductive investments should not only
include numbers and sizes (Rakshit et al.,
1997). Lipid composition and storage
strategy in Mollusca, particularly of
bivalves and gastropods, have been
studied since lipids constitute a major
fraction of Mollusca tissues (Voogt, 1983).
Lipids are major sources of metabolic
energy and essential compounds for the
formation of cell and tissue membranes
(Sargent, 1995), and they are important in
the process of egg production and during
larval development, especially
embryogenesis and metamorphosis. They

The current study was achieved by measure the total lipids and total protein
concentrations in two species of Mollusca (Unio tigridis and Viviparus
bengalensis), and determine the relation between the water temperature, air
temperature and total concentrations of lipids and protein.The total lipid
concentration in (Unio tigridis and Viviparus bengalensis) were ranged between
(39.23 - 25.83%),(22.66 - 16.89 %)respectively. While the concentration of total
protein were ranged between(6.59-3.89 Mg/g), (9.74-4.95 Mg/g) respectively. The
results were showed a positive correlation between air temperature , water
temperature and the concentration of total lipids and total
