Sturgeons are the most primitive, endangered groups of vertebrates on the planet and often referred to as ‘living fossils’. Their natural populations are decreasing due to habitat destruction, blockage of spawning migration, pollution and overexploitation for their expensive black caviar and boneless meat. Currently, existing populations have little chance to survive without artificial breeding and sustainable ranching programmes. Convention on International Trade in Endangered Species (CITES) is regulating international trade of all Acipenseriformes and their products for effective conservation. The aim of this review paper was to describe the main innovative applications in sturgeon aquaculture and conservation, such as genome engineering techniques applied in sturgeon’s reproduction, molecular and ploidy analyses of embryo and larvae, sex determination, genome sequencing, gene expression analysis and genome transplantations. Further research is required to improve cryopreservation techniques, embryo banking and quick identification of disease in sturgeon aquaculture and conservation programme.

水产养殖和and鱼保存的趋势：分子和细胞遗传学工具综述

urge鱼是地球上最原始，濒临灭绝的脊椎动物，通常被称为“活化石”。由于昂贵的黑鱼子酱和无骨肉，栖息地遭到破坏，产卵迁徙受阻，污染和过度开发，自然人口正在减少。当前，如果没有人工育种和可持续的牧场计划，现有种群几乎没有生存的机会。《濒危物种国际贸易公约》（CITES）正在规范所有楔形文字及其产品的国际贸易，以进行有效的保护。本文的目的是描述st鱼水产养殖和保护方面的主要创新应用，例如applications鱼繁殖中应用的基因组工程技术，胚胎和幼虫的分子和倍性分析，性别确定，基因组测序，基因表达分析和基因组移植。在鱼水产养殖和保护计划中，需要进行进一步的研究以改善冷冻保存技术，胚胎储存和快速识别疾病。
