A total of 40 juveniles belonging to a temperate deepwater gnomefish species, , were sampled from littoral habitats (2-5 m depth) of eastern Hong Kong waters in April and May 2017 and March 2019. The presence of gnomefish juveniles in subtropical southern China is reported for the first time at a record low latitude of 22°11'-22°21'N. The specimens were identified based on the gene sequence. The genetic composition between Japan and Hong Kong gnomefish populations were compared by sequencing the mitochondrial Cyt gene, which showed no genetic differentiation. The juveniles ranged from 3.5-10.1 cm ( = 40) in total length, with 35 individuals caught from beds and five from rocky reefs. Our findings highlighted that the littoral habitats in Hong Kong waters, in particular the seasonal beds, are important for small juveniles of .
2017年4月和5月以及2019年3月，从中国香港东部海域的沿岸栖息地（水深2 - 5米）采集了总共40尾属于温带深水驼背鲈的幼鱼。首次报道了在中国亚热带南部的低纬度地区（北纬22°11′ - 22°21′）出现驼背鲈幼鱼。根据 基因序列对标本进行了鉴定。通过对线粒体Cyt基因进行测序，比较了日本和香港驼背鲈种群之间的遗传组成，结果显示没有遗传分化。幼鱼全长范围为3.5 - 10.1厘米（ = 40），其中35尾捕获自 床，5尾捕获自岩礁。我们的研究结果突出表明，香港海域的沿岸栖息地，特别是季节性 床，对驼背鲈幼鱼很重要。
