Morone americana Transcriptome or Gene expression. Morone americana

White perch (Morone americana) are native to lakes, rivers, and estuaries along the Mid-Atlantic and Northeastern seaboards of North America. Given their relatively broad niche distribution, white perch are a key indicator species for ecological monitoring. White perch are temperate basses (Genus Morone), a group of fishes that includes species of economic importance to commercial and recreational fisheries (striped bass, M. saxatilis) and aquaculture (hybrid striped bass, M. saxatilis X M. chrysops). Female reproductive dysfunction (i.e. production of inviable eggs, embryos, and larvae) remains a major obstacle to the expansion of finfish aquaculture and influences recruitment in fisheries and subsequent management practices. The underlying cause(s) of poor egg quality and embryonic mortality of fishes remain unknown. The white perch is a research model for oogenesis of fishes and this ovarian transcriptome is an important resource for future investigations of reproduction and egg quality in temperate basses.

白鲈（Morone americana）原生分布于北美大西洋中部及东北沿海区域的湖泊、河流与河口。由于其生态位分布相对广泛，白鲈是生态监测的关键指示物种。白鲈属于Morone属的温带鲈类，该类群包含对商业及休闲渔业具有重要经济价值的物种（条纹鲈，M. saxatilis）以及可用于水产养殖的物种（杂交条纹鲈，M. saxatilis × M. chrysops）。雌性生殖功能障碍（即产生无活力的卵、胚胎及幼体）仍是制约硬骨鱼水产养殖扩张的主要障碍，同时会影响渔业资源补充及后续的管理措施。目前鱼类卵质不佳与胚胎死亡的根本成因仍未明确。白鲈是鱼类卵子发生研究的模式物种，该卵巢转录组资源可为温带鲈类的繁殖及卵质相关后续研究提供重要支撑。
