随着海洋观赏鱼类在内陆省份养殖推广，海水观赏鱼类幼体的饲料来源缺乏。枝角类是淡水水体的常见种类，容易培养，可得性好，饵质优良，而且多有很强的耐盐能力。那么是否可将内陆淡水枝角类经盐水驯化，作为海洋观赏鱼的饵料?为此，笔者对湖南本地的蚤状进行了耐盐性实验。 As marine ornamental fish are farmed in inland provinces, there is a lack of feed sources for marine ornamental fish larvae. Cladocera is a common species of fresh water bodies, easy to culture, availability, good quality bait, but more than a strong salt tolerance. Is it possible that the inland freshwater Cladoceratum domesticated by salt water as bait for marine ornamental fish? To this end, the author conducted a salt tolerance experiment on the local fleas in Hunan.
