“…In 2006, Okutsu et al [85] developed a spermatogonial transplantation system of rainbow trout. In 2009, Yi et al [86,87] established haploid ES cell lines from medaka gynogenetic haploid embryos, and then created the semi-cloned female medaka which shows normal fertility by using the semi-cloning technology. Currently, most germ cells used for transplantation are derived from juvenile and adult males in a process that typically involves harvest of PGCs in spermatogonial stem cells or spermatogonia.…”

Fish genetic breeding is a process that remolds heritable traits to obtain neotype and improved varieties. For the purpose of genetic improvement, researchers can select for desirable genetic traits, integrate a suite of traits from different donors, or alter the innate genetic traits of a species. These improved varieties have, in many cases, facilitated the development of the aquaculture industry by lowering costs and increasing both quality and yield. In this review, we present the pertinent literatures and summarize the biological bases and application of selection breeding technologies (containing traditional selective breeding, molecular marker-assisted breeding, genome-wide selective breeding and breeding by controlling single-sex groups), integration breeding technologies (containing cross breeding, nuclear transplantation, germline stem cells and germ cells transplantation, artificial gynogenesis, artificial androgenesis and polyploid breeding) and modification breeding technologies (represented by transgenic breeding) in fish genetic breeding. Additionally, we discuss the progress our laboratory has made in the field of chromosomal ploidy breeding of fish, including distant hybridization, gynogenesis, and androgenesis. Finally, we systematically summarize the research status and known problems associated with each technology. fish genetic breeding, genetic improvement, biological method, traits, new variety Citation:

“…Moreover, some differentially expressed genes were identified from the cloned zebrafish embryos at the dome stage [37], and the critical developmental stages for high integration efficiency were determined in zebrafish [38,39]. Stem cell culture and application have been rapidly developed in model fishes of medaka and zebrafish [40,41], and some stem cell technologies, such as gene targeting, germ cell transplantation and semi-cloning by nuclear transfer, have been successfully formed because of specific potentials of fish germ stem cells and embryonic stem cells [42,43]. Especially, Yi et al [44] used the semi-cloning technology to create the semi-cloned female medaka which shows normal fertility and germline transmission over three generations.…”

Aquaculture has been believed to be a major Chinese contribution to the world. In recent 20 years, genome and other genetic technologies have promoted significant advances in basic studies on molecular basis and genetic improvement of aquaculture animals, and complete genomes of some main aquaculture animals have been sequenced or announced to be sequenced since the beginning of this century. Here, we review some significant breakthrough progress of aquaculture genetic improvement technologies including genome technologies, somatic cell nuclear transfer and stem cell technologies, outline the molecular basis of several economically important traits including reproduction, sex, growth, disease resistance, cold tolerance and hypoxia tolerance, and present a series of candidate trait-related genes. Finally, some application cases of genetic improvement are introduced in aquaculture animals, especially in China, and several development trends are highlighted in the near future.

“…Few fish stem cell lines have been obtained so far. An embryonic stem cell line from medaka has been established, which is stable and can differentiate into a variety of cell types to form chimeras of medaka embryos [111,112]. Chen et al [113] reported several embryonic stem cell lines from sea fishes with chimerical competence.…”

Mechanisms of the animal reproductive development are an important research field in life sciences. The study of the reproductive development and regulatory mechanisms in fishes is important for elucidating the mechanisms of animal reproduction. This paper summarizes recent advances in the mechanisms of fish sex determination and differentiation, of fish gonad development and maturation, and of fish germ cell development, as well as the according regulating strategies. Fishes comprise an evolutionary stage that links invertebrates and higher vertebrates. They include diversiform species, and almost all vertebrate types of reproduction have been found in fishes. All these will lead to important advances in the regulatory mechanisms of animal reproduction by using fishes as model organisms. It will also enable novel fish breeding techniques when new controllable on-off strategies of reproduction and/or sex in fishes have been developed. fish, reproduction, regulation Citation:Chen J, Hu W, Zhu Z Y. Progress in studies of fish reproductive development regulation. Chin Sci Bull, 2013, 58: 716, doi: 10.1007/s11434-012-5577-1As low vertebrates, fishes are on an evolutionary stage linking invertebrates and higher vertebrates. There are as many as 28000 known fish species, which show large diversity. A range of sexual characteristics and reproductive strategies has been described for fishes, and almost all reproductive types of vertebrates have been found in fishes. The study of fish reproductive development regulation is important for elucidating mechanisms of animal reproductive development. Molecular breeding will reveal finer varieties when genes and regulatory networks associated with economically important traits (such as fast growth, disease resistance, cold tolerance and hypoxia tolerance) in fishes are discovered [1]. Reproduction also provides a precondition for culturing exclusive fish breeds and expanding fish populations. Breeding techniques such as sexual control and fertility control have played important roles in developing new fish varieties. This paper will review advances of fish reproductive development regulation, with the aim of providing hints for mechanisms of fish reproductive development, as well as providing theoretical guidance for techniques of reproductive regulation and developing highyielding, efficient, eco-friendly breeds.1 Sexual control of fishes Factors influencing sex determinationThe sex differentiation pattern and determination mechanism of fishes are very diverse. Various sexual phenotypes are all present in fishes, such as hermaphroditism, unisexuality, gonochorism and dual reproduction mode including parthenogenesis and sexual reproduction [2]. For those fishes in which sex chromosome systems exist, there are single chromosome systems, such as XX/XY, ZZ/ZW, XX/ XO and ZZ/ZO, and multiple chromosome systems, such as XX/XY 1 Y 2 , ZZ/ZW 1 W 2 , X 1 X 2 X 1 X 2 /X 1 X 2 Y, and X 1 X 2 X 1 X 2 / X 1 X 2 X 1 . Like other animals, fish sex differentiation is controlled by their gene...
