TLDR
In this article, the authors present a blueprint for genetic improvement and new breed creation for aquaculture species and analyze the potential of these new breeding strategies for improving aquaulture seed industry and strengthening food security.Abstract:
Fish biology has been developed for more than 100 years, but some important breakthroughs have been made in the last decade. Early studies commonly concentrated on morphology, phylogenetics, development, growth, reproduction manipulation, and disease control. Recent studies have mostly focused on genetics, molecular biology, genomics, and genome biotechnologies, which have provided a solid foundation for enhancing aquaculture to ensure food security and improving aquatic environments to sustain ecosystem health. Here, we review research advances in five major areas: (1) biological innovations and genomic evolution of four significant fish lineages including non-teleost ray-finned fishes, northern hemisphere sticklebacks, East African cichlid fishes, and East Asian cyprinid fishes; (2) evolutionary fates and consequences of natural polyploid fishes; (3) biological consequences of fish domestication and selection; (4) development and innovation of fish breeding biotechnologies; and (5) applicable approaches and potential of fish genetic breeding biotechnologies. Moreover, five precision breeding biotechniques are examined and discussed in detail including gene editing for the introgression or removal of beneficial or detrimental alleles, use of sex-specific markers for the production of mono-sex populations, controllable primordial germ cell on-off strategy for producing sterile offspring, surrogate broodstock-based strategies to accelerate breeding, and genome incorporation and sexual reproduction regain-based approach to create synthetic polyploids. Based on these scientific and technological advances, we propose a blueprint for genetic improvement and new breed creation for aquaculture species and analyze the potential of these new breeding strategies for improving aquaculture seed industry and strengthening food security.read more

Sex determination mechanisms and sex control approaches in aquaculture animals
TL;DR: This work synthesizes current knowledge of sex determination mechanisms, sex chromosome evolution, reproduction strategies, and sexual dimorphism, and also reviews several approaches for sex control in aquaculture animals, including artificial gynogenesis, application of sex-specific or sex chromosome-linked markers, artificial sex reversal, as well as gene editing.

TL;DR: The Carassius complex of cyprinid teleosts contains sexual tetraploid crucian carp/goldfish and unisexual hexaploid gibel carp/Prussian carp (C. gibelio) lineages, providing a valuable model for studying the evolution and maintenance mechanism of unisexual polyploids in vertebrates as discussed by the authors .

Origin and chromatin remodeling of young X/Y sex chromosomes in catfish with sexual plasticity
Gaorui Gong,Yang Xiong,Shijun Xiao,Xiyang Li,Peipei Huang,Qian Liao,Qingqing Han,Qiaohong Lin,Cheng Dan,Li Zhou,Fan Ren,Qi Zhou,Jian Gu,Jie Mei +13 more
TL;DR: Zhang et al. as mentioned in this paper found that the Y chromosome was at a very early stage of differentiation and no clear evidence of evolutionary strata and classical structure features of recombination suppression for a rather late stage of Y-chromosome evolution were observed.

TL;DR: If the growing aquaculture industry is to sustain its contribution to world fish supplies, it must reduce wild fish inputs in feed and adopt more ecologically sound management practices.

The relation of recombination to mutational advance.
TL;DR: It is shown that this calculation does not apply for mutant genes that act advantageously only when in some special combinations with one or more other mutant genes, and that as far as these cases of special synergism are concerned recombining lines have no evolutionary advantage over non-recombining ones.

TL;DR: Best practices for several NGS methods for genome-wide genetic marker development and genotyping that use restriction enzyme digestion of target genomes to reduce the complexity of the target.

TL;DR: A high-quality reference genome assembly for threespine stickleback fish is developed and it is indicated that reuse of globally shared standing genetic variation has an important role in repeated evolution of distinct marine and freshwater sticklebacks, and in the maintenance of divergent ecotypes during early stages of reproductive isolation.
