متن کاملOccurrence of Two Spirurid Nematodes in Cyprinid Fishes from Nilwala River Basin, Sri Lanka
Characterization of the helminth parasites of wild fish has a considerable importance from the point of view of hygiene and public health, as well as from its taxonomic interest. To study the pathogenecity of parasites in the field of fisheries, require detail knowledge of the parasites inhabiting localities involved.

متن کاملExcess post-hypoxic oxygen consumption is independent from lactate accumulation in two cyprinid fishes.
Carassius carassius responds to hypoxic conditions by conversion of lactate into ethanol, which is excreted over the gills. However, a closely related species, Cyprinus carpio, does not possess the ability to produce ethanol and would be expected to accumulate lactate during hypoxic exposure. While the increase in oxygen consumption in fish required following strenuous exercise or low environme...

متن کاملWater abstraction affects abundance, size-structure and growth of two threatened cyprinid fishes
Hydrologic alteration is a major threat to freshwater biota, and particularly fish, in many river courses around the world. We analyzed and compared the effects of water abstraction on two threatened cyprinid fishes of contrasting ecology (the Mediterranean barbel Barbus meridionalis and the Catalan chub Squalius laietanus) in a Mediterranean stream. We compared abundance, size-structure, growt...
