轮虫属于轮虫纲,是多种海洋动物幼体最好的饵料之一。它的甲壳长度是150~250微米。对轮虫的消耗数量是很大的。例如1尾真鲷稚鱼,到它生长到总长10毫米时,约在25天内要消耗12000~15000只轮虫。除了这些直接被稚鱼消耗的轮虫外,投放的大量轮虫是为了使其保持一定的密度,以便使稚鱼能够随时进行摄食。因此,实际给予1尾真鲷稚鱼的轮虫数,大约是被它直接消耗的3
Rotifers are rotifers, is one of the best feed for many marine animal larvae. Its carapace length is 150 to 250 microns. The consumption of rotifers is very large. For example, a juvenile red sea bream, until it grows to a total length of 10 mm, consumes about 12,000 to 15,000 rotifers in about 25 days. In addition to these rotifers, which are consumed directly by juveniles, a large number of rotifers are put in order to maintain a certain density in order to allow juvenile fish to feed at any time. Therefore, the number of rotifers actually administered to a juvenile red sea bream is approximately 3
