Ontogenetic changes in meristic measurements of silver carp and bighead carp.
The study analyzed 30 exterior meristic characters for 255 silver and bighead carp samples of 1- to 5-year-old collected from the National Primary Breeding Farm at Laojianghe Lake at the Middle Reach of the Yangtze River. Multivariate analysis was performed. In silver carp, the Euclidean distance was the greatest between the 1-year-old group and other age groups. Silver carp individuals were co...
متن کاملBighead Carp
In the United States, bighead are polycultured with channel catfish in approximately 5,100 acres of earthen ponds, including an estimated 4,000 acres in Arkansas, 500 in Mississippi, and 600 in Alabama. Bighead are an important source of additional income that, at times of low catfish prices, has kept some fish farmers in business. The primary market is to live-haulers who sell to specialty mar...
متن کاملAspects 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,...
متن کاملCharacterization and Comparative Profiling of MiRNA Transcriptomes in Bighead Carp and Silver Carp
MicroRNAs (miRNAs) are small non-coding RNA molecules that are processed from large 'hairpin' precursors and function as post-transcriptional regulators of target genes. Although many individual miRNAs have recently been extensively studied, there has been very little research on miRNA transcriptomes in teleost fishes. By using high throughput sequencing technology, we have identified 167 and 1...
متن کاملSwimming 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...
