چکیده

Abstract Several indicators show that the world population is rapidly increasing with prospects of reaching close to 10 billion people in 2050. Optimal production fish a tentative goal ensure human feeding and resources sustainability. The present study was performed on eggs silver carp, collected during breeding season consecutive years different environmental temperature profiles at Deroua Fisheries Station evaluate seasonal inter-seasonal changes quality order promote predictive marker for optimal carp. viability obtained detected using ANOVA followed by Tukey test analyze fertilization rate, embryos survival fry rate. Data analysis showed no significant difference rate two seasons, therefore these can not be used as an adequate criterion predict Although did change first season, it changed significantly second when there increase temperature. This factor could responsible disturbance females' oogenesis consequently degradation eggs' quality. results parameter yield carp rather than success embryos. paper discusses importance scope this approach.

Swimming performance of adult bighead carp Hypophthalmichthys nobilis (Richardson, 1845) and silver carp H.molitrix (Valenciennes, 1844)

Although the movement of invasive bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix) in the Upper Mississippi River system is dependent on their ability to swim through its numerous lockanddams, the swimming performance of adults of these species is at present unknown. Using a large (2,935L) mobile swim tunnel, the swimming performance of adult bighead and adult silver carp...

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,...

The Effect of Different Pre-Fried Temperatures on Physical and Chemical Characteristics of Silver Carp Fish (Hypophthalmichthys molitrix) Nuggets

In present study the effect of different pre-frying temperatures in sunflower oil on physical and chemical characteristics of silver carp fish nuggets (Hypophthalmichthys molitrix) were studied. After prepared, the fish nuggets were pre-fried in sunflower oil heated to 150, 170 and 190°C. The measurements included: the proximate composition (protein, moisture, fat and ash), physical experiments...

Risk assessment of microcystins in silver carp (Hypophthalmichthys molitrix) from eight eutrophic lakes in China.

Bioaccumulation and risk assessment of microcystins (MCs) in muscle of silver carp (Hypophthalmichthys molitrix) from eight eutrophic lakes along the Yangtze River of China were examined by using liquid chromatography electrospray ionisation mass spectrometry. MCs contents in seston collected from these eutrophic lakes ranged from 0.02 to 21.7 μg/L. MCs concentrations in silver carp muscle samp...
