Study of prophenoloxidase activating system of freshwater crayfish (Pontastacus leptodactylus)
Phenoloxidase (Po) activity was measusred spectrophotometrically in serum, plasma and haemocytes (HLS) of the freshwater crayfish (Pontastacus leptodactylus). The highest activity was found in HLS suggesting that the haemocytes are the major source of the Po or its proform prophenoloxidase (proPO) in crayfish. Furthermore, the enzyme activity in serum samples was reduced after freezing the samp...

متن کاملWater use in LCA: managing the planet’s freshwater resources
Freshwater is one of the planet’s most valuable resources being an essential life-sustaining element which cannot be substituted. Acting as the source of drinking water and the basis for hygiene and food supply, it is indispensable for humans, while at the same time ensuring biodiversity and pivotal ecosystem functions on which ultimately we all depend. We are witnessing a steadily worsening si...
متن کاملExperimentally pathogenesis of Aeromonas hydrophila in freshwater Crayfish (Astacus leptodactylus) in iran
In this research the affect of A. hydrophila on pathogenesis of Crayfish A. leptodactylus was carried out. This study was designed in three groups as treatments and one group as control in triplicate with 20 Crayfish in each glass aquarium. The treatments have exposed to A. hydrophila. The concentrations of the bacteria in treatments were ...
