The presence of these extra chromosomes in the nucleus requires a corresponding increase in nuclear (and cellular) size which provides the key to separating diploids and triploids efficiently. The use of triploid grass carp as a legitimate alternative. fish originating from the legal stocking events in Devils Lake.

The grass carp (Ctenopharyngodon idella) occurs natu-rally in large rivers of eastern China and the former Soviet Union. Gynogenesis or triploidy have been induced in grass carp (Cassani & Caton, ; Allen et al., ), silver carp (Anon., a; Mizra & Shelton, ), bighead carp (Aldridge et al., ), and mud carp (Yu et al., ).
Chromosome manipulation has found some practical applications with rainbow trout and grass carp, but so far not with any of. Grass carp were first brought into the U.S. in for aquatic plant control research. Many researchers viewed the fish as being a natural weed control agent.
However, fears of reproducing populations and reports of environmental damage caused most states to prohibit their use. The formation of all-female diploid and triploid crucian carp provides the excellent platform to investigate the sex differentiation of the primordial germ cells (PGCs) In this aspect, we clearly know the PGCs of all-female diploid and triploid crucian carp will finally develop into oogonia and mature ova So we can observe how the PGCs Cited by: Read more about Laboratory culture of triploid grass carp Code of practice for small fish farms and fish processing plants Alberta Government Library*The move to Codes of Practice does not affect the full range of prevention and enforcement response tools available under the Environmental Protection and Enhancement Act to respond to non-compliance.
triploid grass carp is a slow process, but once control is achieved.it will last a number of years. If more rapid control is desired, other plant control methods such as mechanical harvesting or chemical applications can be integrated with triploid grass carp use. Recommended Initial Triploid Grass Carp.
Florida permits the release of triploid grass carp, but some states do not allow triploids (e.g., Maryland), and some states such as Michigan have banned the release of any grass carp.
Florida requires that the released fish are certified triploid and that a permit is obtained for use, possession and removal of grass carp.
Triploid Grass Carp Grass carp (Ctenopharyngodon idella) is a species of fish which eats aquatic vegetation and is native to large river systems of eastern Asia (They are sometimes called white amur, because they are found in the Amur River).

InPennsylvania made it legal to import grass carp as long as they are the triploid variety. This means they have been bred to have an extra set of chromosomes and are therefore sterile.
Triploid grass carp are not able to reproduce and spread out of control. Grass carp rely almost entirely on aquatic plants for their diet.

This riverine herbivorous fish is the largest fish in the minnow family. allow stocking of diploid Grass Carp to control nuisance aquatic vegetation (Alabama, Arkansas, Colorado, Iowa, Mississippi, Missouri, and Nebraska).” “Each of these diploid states border at least two other states that either prohibit all Grass Carp or restrict their use to triploid Grass Carp only.”.
The key difference between diploid and triploid grass carp is that diploid grass carp is a fish species that possess two sets of chromosomes and is able to reproduce while triploid grass is a sterile fish species that possess three sets of chromosomes including an extra set of chromosomes.
Home page for the Triploid Grass Carp Inspection and Certification Program. The U.S. Fish and Wildlife Service (USFWS) offers a triploid grass carp inspection service for natural resource agencies in the United States and in other countries, to help States and others protect their aquatic habitats.
The inspection program is to provide assurance to these agencies, and others concerned about. And fear not, grass carp are not known as being predatory, and our own observations of triploid grass carp stomachs from Lake Austin revealed a whole lot of plant material, but no fish bones (Fig.
