摘要: 根据2014年夏季、2016年夏季与2017年夏季3个航次的黄海近岸海域产卵场调查数据,采用服从Tweedie分布的广义加性模型(GAM),对黄海近岸海域短吻红舌鳎产卵场的空间分布及其年际变化进行了研究。结果表明: 短吻红舌鳎的产卵场主要分布在海州湾(34°00′—35°18′ N,119°30′—121°30′ E)、苏北浅滩(32°18′—34°00′ N,120°18′—122°00′ E)海域范围内,而山东半岛南部海域(34°42′—36°48′ N,119°30′—122°00′ E)鱼卵数量较少。短吻红舌鳎产卵场的空间分布与经纬度、水深及海水表层温度均显著相关,与海水表层盐度、表层叶绿素a相关性不显著;其最适水深、海水表层温度、海水表层盐度、表层叶绿素a浓度范围分别为15~26 m、29~32 ℃、22~25和0.10~3 mg·m-3。短吻红舌鳎产卵场的空间分布及其影响因子存在一定的年际变化,总体上其产卵场分布较为稳定,但表层温度较高的年份可能存在北移的趋势。

Abstract: With survey data from three voyages in the summer of 2014, 2016, and 2017, spatial distribution and inter-annual variability of spawning grounds of Cynoglossus joyneri in the coastal waters of Yellow Sea were examined based on Tweedie-generalized additive model (GAM). The results showed that the spawning grounds of C. joyneri mainly distributed in the Haizhou Bay ranging within 34°00′-35°18′ N, 119°30′-121°30′ E. The other one in Subei Shoal 32°18′-34°00′ N, 120°18′-122°00′ E. Fish eggs of C. joyneri were few in the southern waters of Shandong Peninsula 34°42′-36°48′ N, 119°30′-122°00′ E. The distribution of fish eggs was significantly related to the location (i.e., longitude and latitude), depth, and sea surface temperature, and did not relate to the sea surface salinity and surface chlorophyll a. The optimal range of depth, sea surface temperature, sea surface salinity, and surface chlorophyll a were 15-26 m, 29-32 ℃, 22-25 and 0.10-3 mg·m-3, respectively. There was notable inter-annual variability in the spatial distribution of spawning grounds of C. joyneri and its influencing factors. Overall, the distribution of spawning grounds is relatively stable, but potentially move northward in the year with high sea surface temperature.
