将Eggers模型移入实验室大型玻璃钢水槽中,采用3种室内可能得到的实验饵料:冷冻细脚长(Themistogra cilipes)、天然成体卤虫(Artemissalina)和小黄鱼糜(Fishsilage),在流水条件下,比较黄渤海主要中上层小型鱼类玉筋鱼(Ammodytepersonatus)对上述3种饵料的摄食、生长和生态转换效率等生态能量学特征。结果显示,3种饵料中,虽然玉筋鱼对细脚长的能量生态转换效率较高,但是其湿重摄食量[g/(100g·d)FW]和能量摄食量[kJ/(100g·d)]都比较低,生长情况较差;卤虫的食物生态转换效率较高,湿重摄食量较多、生长情况较好;鱼糜的能量摄食量较多,生长情况介于两者之间,但其生态转换效率均较低。与自然生长的玉筋鱼相比,摄食卤虫的玉筋鱼较接近于自然生长。研究结论认为,室内玉筋鱼的模拟实验,在不能获得自然活体饵料的情况下,卤虫不失为一个理想的选择。
The Eggers model was moved into a large glass-fiber reinforced plastic laboratory sink using three laboratory possible experimental diets: Themistogra cilipes, Artemissalina, and Fishsilage. Under flowing conditions, The eco-energetic characteristics such as feeding, growth and ecological conversion efficiency of Ammodytepersonatus, a major pelagic fish in the upper and middle reaches of the Yellow Sea and the Bohai Sea, were compared. The results showed that the feed intake [g / (100 g · d) FW] and energy intake [kJ / (100 g · D)] are relatively low, the growth is poor; Artemia insect food ecological conversion efficiency is higher, wet weight more food intake, growth is better; surimi energy food intake more, growth in between the two However, its ecological conversion efficiency is low. Compared with the natural growth of jade fish, Artemia feeding Artemia closer to the natural growth. The conclusion of the study is that Artemisia fuscus simulation experiment, in the case can not get the natural live bait, Artemia are an ideal choice.
