摘要: |
为了解大亚湾核心区游泳动物卵和幼体的种类和数量,研究于2020年 5月和10月对大亚湾3个重要的游泳动物卵和幼体分布较为密集区域(27个站位)开展了定量取样调查。5月共采集卵和幼体1 660尾(粒),经COI鉴定分析,共鉴定出84种,隶属于4门11目48科64属,其中包含鱼类60种,虾类9种,蟹类12种,软体动物1种;10月共采集卵和幼体1 580尾(粒),经COI鉴定分析,共鉴定出62种,隶属于2门11目40科53属。其中包含鱼类47种,虾类10种,蟹类4种,虾蛄1种。对比历史数据,鉴定结果表明DNA 条形码技术是传统形态学强有力的补充,是一种准确的、规范化的、有效的物种鉴定工具。

Abstract: |
In order to understand the species and quantity of nekton eggs and larvae in the core area of Daya Bay, a quantitative sampling survey was conducted in May and October 2020 in three areas (27 stations) where the distribution of nekton eggs and larvae was relatively dense. A total of 1 660 nekton eggs and larvae were collected in May. A total of 84 species were identified by COI analysis, belonging to 4 phyla, 11 orders, 48 families and 64 genera, including 60 species of fish, 9 species of shrimp, 12 species of crab and 1 species of mollusk. A total of 1580 eggs and larvae were collected in October. A total of 62 species were identified by COI analysis, belonging to 2 phyla, 11 orders, 40 families and 53 genera. There were 47 species of fish, 10 species of shrimps, 4 species of crabs and 1 species of mantis shrimps. Compare to historical data, our results demonstrate that being a powerful complement to traditional morphology, DNA barcoding is an accurate, standardized, and efficient tool for species identification, and possesses a broad prospect of application in fish biodiversity research
