Yellow porgy Taius tumifrons is a demersal fish with higher economic and admiring viewing values .

本文就温度、作业海域的深度、起网速度对黄鲷采捕成活率的影响进行了研究。

The paper makes a study on the effect of temperature , depth of operation waters and hauling speed on the harvesting survival rate of yellow porgy .

前鳃盖骨后缘下角出现2个扩大且尖锐的棘，是鉴别黄鲷仔鱼的标志之一。

The appearance of2 large and sharp spines at lower angle of external edge of the preopercle is also the symbol of the larval Dentex tumifrons .

结果表明：在16~26℃范围内，黄鲷胚胎都能孵出仔鱼，孵化速度随水温上升而加快。

The experimental result showed that the embryo could be hatched out at the range of 16-26 ℃ . With rising of the water temperature the speed of the hatching was expedited .

结果表明：（1）黄鲷受精卵和初孵仔鱼比其他鲷科鱼类的略小，受精卵径为0.834~0.998mm、油球直径为0.184~0.198mm、初孵仔鱼全长2.25mm。
