Amphibians are hosts for a wide variety of ecto- and endoparasites, such as protozoans and parasitic worms. Naididae is a family of Oligochaeta whose species live on a wide range of substrates, including mollusks, aquatic macrophytes, sponges, mosses, liverworts, and filamentous algae. However, some species are known as endoparasitic from vertebrates, such as Dero (Allodero) lutzi, which is par...
Abstract: The distributions of the product |XY | and the ratio |X/Y | are derived when X and Y are Pearson type VII and Laplace random variables distributed independently of each other. Extensive tabulations of the associated percentage points are also given. Zusammenfassung: Die Verteilungen des Produkts |XY | und des Quotienten |X/Y | sind hergeleitet, falls X und Y unabhängig verteilte Pears...
Many fish culturists are interested in applying copper sulfate pentahydrate (CSP) to channel catfish, Ictalurus punctatus, nursery ponds as a prophylactic treatment for trematode infection and proliferative gill disease by killing snails and Dero sp., respectively, before stocking fry. However, copper is an algaecide and may adversely affect phytoplankton and zooplankton populations. We evaluat...
The present study was conducted to determine heavy metal (cadmium and chromium) concentrations in gills, kidneys, liver, skin, muscles and scales of three fish species (Catla catla, Labeo rohita and Cirrhina mrigala) from three stations viz. Lahore Siphon (Up stream), Shahdera Bridge and Baloki Headworks (Down stream) in the river Ravi, Pakistan. Heavy metal concentrations varied significantly ...
Two 90 days experimental trials were conducted to evaluate the effect of artificial diet (35% protein) on sensory quality of yearlings of Indian major carps (Labeo rohita, Cirrhinus mrigala and Catla catla). Experimental diet was given at 3% of fish wet body weight per day. After 90 days trial organoleptic study of fried fish was carried out by twelve panelists using hedonic scale for each spec...
We examined and compared heavy metals bioaccumulation in Cyprinus carpio and Labeo rohita netted from Sardaryab, a tributary of River Kabul. By using atomic absorption spectrometry we assessed different organs including livers, gills, and muscles. Metals studied were chromium, iron, zinc, lead, and copper. Livers of both species showed higher concentrations of metals while muscles showed the le...
