Aquatic environments get contaminated with pesticide and heavy metal residues that causes water pollution.The excessive use of pesticides in agriculture has sparkled the interest of scientists in investigating the harmful effects of these compounds. The present study evaluates the pesticides Atrazine and Roundup (glyphosate) on biochemical and molecular aspects of Biomphalaria alexandrina snails, also to evaluate the pesticides Malathion and Deltamethrin on biological and biochemical parameters of Helisoma duryi snails.also the effect of aluminum chloride (AlCl3), and zinc sulphate...

The present work evaluates the molluscicidal activities of certain plant extracts (water suspension, Cold water, Boiled water, methanol, ethanol, acetone and chloroform extract). The data obtained from preliminary screening tests conducted on 10 plant species belonging to 10 different families. The effect of low concentrations of different synthetic and natural mollusciciding agents may introduce to fresh water environment on reproduction and biochemical aspects of Biomphalaria alexandrina was studied. Different mollusciciding agents (copper sulphate, Bayluscide, Uccmaluscide, Agave...

The present investigation focuses on the change in some physiological parameters concerning the liver and kidney functions induced after experimental oral infection of the albino mouse, Mus musculus, with the metacercariae of prohemistomum vivax. These were obtained from the skeletal muscles of the Nile fishes Oreochromis niloticus, Clarias gariepinus and Bagrus bajad. Also, Native SDS-Proteins lactate dehydrogenase (LDH), Glucose-6-phosphate dehydrogenase(G6PDH) , 6-phosphogluconate dehydrogenase (6PGDH) , acid phosphatase (ACP) and alkaline phosphatase (ALP) in liver and kidney tissues of...

The edible crustaceans, Erugosquilla massavensis, Penaeus semisulcatus, Metapenaeus monoceros (shrimps) and Portunus pelagicus (crab), from different regions are important components of the aquatic fauna . These edible crustaceans can be beneficial as nutraceutical and pharmaceutical components, if we can use in the treatment of some diseases. So, the purpose of the present work was, therefore, to assess the protein, carbohydrates, and lipids, vitamins (B1, B2), minerals (K, Na, Ca, P, S) of these species, which may in the future play an important role in some pharmaceutical industries and...
