Genetically modified triploid fish are more susceptible to temperature stress, have a higher incidence of deformities (e.g. abnormalities in the eye and lower jaw [52]), and are less aggressive than diploids. [53] [54] Other welfare concerns of GM fish include increased stress under oxygen-deprived conditions caused by increased need for oxygen ...
Schizopygopsis przewalskii (common name: Przewalskii's naked carp; in Chinese: 青海湖裸鲤; lit. 'Qinghai Lake naked carp') is a species of cyprinid that is endemic to the Lake Qinghai basin in China, where it is the dominant fish species (the other natives are four Triplophysa loaches).
The four dominant fish species known in the United States as Asian carp are introduced invasive species.They all cause harm within their new environments. Specifically, the four most well-known species of invasive Asian carp are black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix), and bighead carp (Hypophthalmichthys nobilis).
Asian carp is an informal grouping of several species of cyprinid freshwater fishes native to Eurasia, commonly referring to the four East Asian species silver carp, bighead carp, grass carp (a.k.a. white amur) and black carp (a.k.a. black amur), [note 1] which were introduced to North America during the 1970s and now regarded as invasive in the United States.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Common carp by Alexander Francis Lydon. The type subspecies is Cyprinus carpio carpio, native to much of Europe (notably the Danube and Volga rivers). [2] [4]The subspecies Cyprinus carpio haematopterus (Amur carp), native to eastern Asia, was recognized in the past, [4] but recent authorities treat it as a separate species under the name Cyprinus rubrofuscus.
Triploid organisms, for instance, are usually sterile. Because of this, triploidy is commonly exploited in agriculture to produce seedless fruit such as bananas and watermelons. If the fertilization of human gametes results in three sets of chromosomes, the condition is called triploid syndrome. [citation needed]
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species ; only 1,270 of these remain ...
