The contribution of aquaculture systems to global aquaculture production
Abstract Since 2000, aquaculture became well‐integrated into the global food system. Aquaculture systems are highly diverse, producing globally equal amounts of fed and extractive species. In Asia and Africa, inland aquaculture provides the bulk of aquaculture production, while in the Americas, Europe, and Oceania, marine aquaculture dominates.

Abstract Interspecies crossing and allopolyploidization increase the opportunity for generating new breeding resources for fish farming. Allotetraploid hybrid fish (4nAT) were created by crossing red crucian carp (RCC, Carassius auratus red var., ♀) with common carp (CC, Cyprinus carpio L., ♂).

Background Sperm abnormalities are one of the primary factors leading to male sterility, but their pathogenesis is still unclear. Although miRNAs are suggested to exert important roles in the regulation of spermatogenesis at both transcriptional and ...

Erythrocyte Profile of Diploid and Triploid Silver Crucian Carp (Carassius auratus) [PDF]
Haematological analysis was performed on 27 adult specimens of Carassius auratus irrespective of sex in 2003 and on 32 juveniles of distinguished sex in 2004. In this study we found that the ploidy level affected significantly ( p < 0.01) the values ...

Organization and variation analysis of 5S rDNA in different ploidy-level hybrids of red crucian carp × topmouth culter. [PDF]
Through distant crossing, diploid, triploid and tetraploid hybrids of red crucian carp (Carassius auratus red var., RCC♀, Cyprininae, 2n = 100) × topmouth culter (Erythroculter ilishaeformis Bleeker, TC♂, Cultrinae, 2n = 48) were successfully produced ...

High hydrostatic pressure (HHP) causes depolymerization of the spindle microtubules. HHP applied to fish eggs prevents extrusion of the second polar body and inhibits the first cell cleavage, and it is used to produce triploids and diploid gynogenetic and androgenetic individuals.

[The genetic diversity of diploid and triploid crucian carp from six populations in Heilongjiang River System]. [PDF]
Twelve microsatellite markers from silver crucian carp were used to investigate the genetic structuring of the diploid and triploid crucian carp from six natural populations in Heilongjiang River System. In the six populations, the number of average allele (A) is from 5.8 to 6.8, the number of effective allele (Ne) is from 2.8 to 4.6, the expected ...
