Abstract

This review synthesizes the state of global anuran breeding research as of early 2026, highlighting a dual mandate: the urgent conservation of biodiversity amidst the global amphibian crisis and the sustainable intensification of commercial aquaculture. While these fields have historically operated in parallel, they increasingly share critical methodologies. We examine advancements in assisted reproductive technologies (ARTs), particularly the refinement of hormonal induction protocols and the widespread adoption of computer-assisted sperm analysis (CASA). Significant attention is given to the cryobiological bottleneck; while sperm cryopreservation is now a robust tool for biobanking, the preservation of oocytes remains elusive due to biophysical challenges such as chilling injury and lipid phase transitions. We discuss the emergence of embryonic cell cryopreservation and somatic cell nuclear transfer (SCNT) as viable alternatives for banking and restoring diploid genomes, exemplified by the Lazarus Project. Furthermore, the review analyzes the genomic revolution in anurans, contrasting the advanced gene-editing capabilities in model Xenopus species with the nascent but accelerating genomic selection in commercial species like the American bullfrog (Aquarana catesbeiana). The integration of these technologies promises to secure genetic diversity for endangered species while optimizing growth and disease resistance in the aquaculture sector.

全球无尾鲟育种进展：保护性生物技术与商业水产养殖整合的综述

本文综述了截至2026年初全球两栖动物育种研究的现状，强调了双重任务：在全球两栖动物危机中迫切需要保护生物多样性和商业水产养殖的可持续发展。虽然这些领域在历史上是并行运行的，但它们越来越多地共享关键方法。我们研究了辅助生殖技术（ARTs）的进步，特别是激素诱导方案的改进和计算机辅助精子分析（CASA）的广泛采用。重点关注低温生物学瓶颈；虽然精子冷冻保存现在是一种强大的生物银行工具，但由于冷损伤和脂质相变等生物物理挑战，卵母细胞的保存仍然难以捉摸。我们讨论了胚胎细胞冷冻保存和体细胞核移植（SCNT）作为储存和恢复二倍体基因组的可行替代方案的出现，以拉撒路计划为例。此外，本文还分析了无尾动物的基因组革命，将模式非洲爪蟾物种的先进基因编辑能力与美国牛蛙（Aquarana catesbeiana）等商业物种的新兴但正在加速的基因组选择进行了对比。这些技术的整合有望确保濒危物种的遗传多样性，同时优化水产养殖部门的生长和抗病能力。

期刊介绍： Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture. The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more. This is the official Journal of the European Aquaculture Society.
