Sampling of eggs of species of family Engraulidae was investigated at three stations in the nearshore waters of Gulf of Mannar, for the period of January 2018 to December 2018. During sampling, the quantities and distributions of eggs of engraulids were determined. Horizontal tow was conducted from the surface (0-5 m), a plankton net of 45 cm in diameter and 150 μm mesh. The eggs of engraulids sampled in plankton tows were found to be 542.92 ind./100 m³. A total of 1,075 eggs belonging to 8 species were identified during the sampling period. Eggs of Encrasicholina heteroloba, E. punctifer, Setipinna taty, Stolephorus baganensis, S. tri, Thryssa hamiltonii, T. dussumieri and T. mystax were identified. Engraulid eggs were found throughout the year in the nearshore waters of Punnakayal and Thoothukudi, but they were much abundant during the summer season. A significant positive correlation was found between environmental factors and the occurrence of eggs at Thoothukudi and Punnakayal stations. Thus Punnakayal region of Gulf of Mannar is identified as the spawning ground for the engraulid fishes.

印度东南海岸曼纳尔湾海域的吞噬卵的形态鉴定和发生

在2018年1月至2018年12月期间，在马纳尔湾近岸水域的三个站点对Engraulidae科的卵进行了抽样调查。在抽样过程中，确定了engraulidad卵的数量和分布。从表面（0-5 m），直径为45 cm和150μm网眼的浮游生物网进行水平拖曳。在浮游生物丝束中采样的草食性卵为542.92 ind./100 m ³。在抽样期间，共发现了8种1075个卵。的鸡蛋Encrasicholina heteroloba，E. punctifer，黄鲫，Stolephorus baganensis，S.三，赤鼻棱hamiltonii，鉴定出杜氏锥虫和mystax虫。全年在普纳卡亚尔（Punnakayal）和通祖迪（Thoothukudi）的近岸水域中都发现了引人入胜的卵，但在夏季它们很多。发现环境因素与Thoothukudi和Punnakayal站卵的发生之间存在显着的正相关。因此，Mannar海湾的Punnakayal地区被确定为诱食鱼类的产卵场。
