Wild abalone (Family ) populations have been severely affected by commercial fishing, poaching, anthropogenic pollution, environment and climate changes. These issues have stimulated an increase in aquaculture production; however production growth has been slow due to a lack of genetic knowledge and resources. We have sequenced a draft genome for the commercially important temperate Australian 'greenlip' abalone (, Donovan 1808) and generated 11 tissue transcriptomes from a female adult abalone. Phylogenetic analysis of the greenlip abalone with reference to the Pacific abalone () indicates that these abalone species diverged approximately 71 million years ago. This study presents an in-depth analysis into the features of reproductive dysfunction, where we provide the putative biochemical messenger components (neuropeptides) that may regulate reproduction including gonad maturation and spawning. Indeed, we isolate the egg-laying hormone neuropeptide and under trial conditions induce spawning at 80% efficiency. Altogether, we provide a solid platform for further studies aimed at stimulating advances in abalone aquaculture production. The genome and resources are made available to the public on the abalone 'omics website, http://abalonedb.org.
野生鲍鱼（Family ）种群受到商业捕捞、偷猎、人为污染、环境和气候变化的严重影响。这些问题刺激了水产养殖产量的增加；然而，由于缺乏遗传知识和资源，生产增长缓慢。我们已经为商业上重要的温带澳大利亚“绿唇”鲍鱼（, Donovan 1808）测序了一个草案基因组，并从一只成年雌性鲍鱼中生成了 11 种组织转录组。绿唇鲍鱼与太平洋鲍鱼（）的系统发育分析表明，这些鲍鱼物种大约在 7100 万年前分化。本研究对生殖功能障碍的特征进行了深入分析，提供了可能调节生殖包括性腺成熟和产卵的假定生化信使成分（神经肽）。事实上，我们分离出产卵激素神经肽，并在试验条件下以 80%的效率诱导产卵。总之，我们为旨在刺激鲍鱼水产养殖生产进步的进一步研究提供了坚实的平台。基因组和资源可在鲍鱼“组学”网站 http://abalonedb.org 上公开获取。
