摘　　要：为了解黄海北部近岸海域鱼卵、仔稚鱼资源状况,2009年5月、7月、9月、10月采用水平和垂直拖网对该海域鱼卵、仔稚鱼种类组成与数量分布开展调查。共设站位38个,每站表层水平拖网10 min,拖网速度为2.5~3.0 nmile·h-1;垂直拖网由底到表,拖网速度约0.5 m·s^-1。结果表明:2009年4个航次调查共捕获鱼卵178467粒、仔稚鱼138尾,共计31种。其中鳀(Engraulis japonicus)、鮻(Liza haematocheilus)、皮氏叫姑鱼(Johnius belangerii)、斑鰶(Konosirus punctatus)、赫氏高眼鲽(Cleisthenes herzensteini)、凤鲚(Coilia mystus)等是主要产卵群体,分别占捕获鱼卵、仔稚鱼总量的96.67%、0.83%、0.69%、0.28%、0.26%、0.24%;主要种类产卵期均为5月,大洋河河口、碧流河河口、英那河河口海域为主要产卵区域。Investigation on species composition and quantity distribution of fish eggs and larvae was carried out in coastal waters of the north Yellow Sea in May,July,September,October 2009 by horizontal and vertical tows with zooplankton nets.The four cruises were conducted at the same 38 stations,and the horizontal tows were at 10 min duration with a speed of 2.5-3.0 nmile·h-1 on the sea surface,while the vertical tows were from surface to near-bottom at a speed of 0.5 m·s^-1 at each sampling station.According to the investigation results,178467 eggs and 138 larvae of fishes belonging to 31 taxa were collected from May and October 2009.Engraulis japonicus,Liza haematocheilus,Johnius belengeri,Konosirus punctatus,Cleisthenes herzensteini,Coilia mystus were the main spawning groups,accounting for 96.67%,0.83%,0.69%,0.28%,0.26%,0.24%of the total fish and eggs,and the spawning period was May.The main spawning areas were in Dayang River Estuary,Biliu River Estuary and Yingna River Estuary.
