Metals are the major pollutants in aquatic environment. A lot of research literature is available globally about accumulation of heavy metals in aquatic ecosystems as well as in different body organs of aquatic animals, especially fish. Heavy metals mainly generate reactive oxygen species (ROS) in aquatic animals that lead to oxidative stress production. ROS cause oxidative damage to different ...

An imminent threat to indigenous freshwater ichthyofauna is the introduction of alien fishes that can alter behavior, population dynamics and native community structure. Thus, it necessary understand their feeding behaviour avoid any unwanted incalculable loss. At sampling site, Head Baloki habits both (L. calbasu, C. catla, L. rohita mrigala) (H. nobilis, H. molitrix, carpio, idella, auratus, ...

Major carps, native freshwater fish in South Asian nations, are economically valuable species with high market demand. Coastal rural people can cultivate them their own seasonal, largely underutilized, small homestead ponds low input and understanding. However, the major problems production this region lack of quality carp seed appropriate culture techniques. Therefore, research was carried out...

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 ...

The aim of the study was to investigate the physical difference in biochemical characteristics of spermatological and seminal plasma and also ultrastructure of spermatozoa in six carp species, viz. catla, Catla catla, rohu, Labeo rohita, kalbasu, Labeo calbasu, mrigal, Cirrhinus mrigala, silver carp, Hypophthalmichthys molitrix and grass carp, Ctenopharyngodon idella. Semen yield from different...
