Optimization of high density long duration transportation of silver carp (Hypophthalmichthys molitrix) and rui (Labeo rohita) fingerlings

Aspects of Embryonic and Larval Development in Bighead Carp Hypophthalmichthys nobilis and Silver Carp Hypophthalmichthys molitrix

As bighead carp Hypophthalmichthysnobilis and silver carp H. molitrix (the bigheaded carps) are poised to enter the Laurentian Great Lakes and potentially damage the region's economically important fishery, information on developmental rates and behaviors of carps is critical to assessing their ability to establish sustainable populations within the Great Lakes basin. In laboratory experiments,...

Histology of gills of Labeo rohita and Hypophthalmichthys molitrix infested by monogenean and copepod parasites

The present study was conducted to reveal a histological analysis on the gills of Labeo rohita and Hypophthalmichthys molitrix specimens were observed to reveal the histo-pathological characteristics of the gills of these freshwater carps. The histological examination of the gills of Labeo rohita revealed the proliferation of bronchial tips, shortening and fusion of secondary gill lamellae, des...

Pathogen Susceptibility of Silver Carp (Hypophthalmichthys molitrix) and Bighead Carp (Hypophthalmichthys nobilis) in the Wabash River Watershed

Impact of Cypermethrin on Fingerlings of Common Edible Carp (Labeo rohita)

Laboratory evaluations were made to assess the toxicological and biochemical effect of cypermethrin on fingerlings of common edible freshwater culture carp (Labeo rohita). There was a significant negative (P < 0.05) correlation observed between effective doses of cypermethrin and exposure periods; that is, LC₅₀ values decreased from 0.323 μg/L (6 h) to  > 0.278 μg/L (12 h),  > 0.240 μg/L (18 h)...

Digestive proteases of three carps Catla catla, Labeo rohita and Hypophthalmichthys molitrix: partial characterization and protein hydrolysis efficiency

Characteristics and functional efficacy of digestive proteases of Catla catla, catla, Labeo rohita, rohu and Hypophthalmichthys molitrix, silver carp were studied. Total protease activity was significantly (P < 0.05) higher in rohu (1.219 ± 0.059 U mg protein min) followed by silver carp (1.084 ± 0.061 U mg protein min), and catla (0.193 ± 0.006 U mg protein min). Trypsin activity of silver car...
