US researchers refine new incubation technique for catfish eggs

摘要

Researchers in the United States have developed a new incubation technique for channel catfish eggs using a process that moves increased amounts of oxygen-rich water through spawning troughs.Les Torrans, research fishery biologist and project leader at the United States Department of Agriculture's (USDA) Warmwater Aquaculture Research Unit, National Warmwater Aquaculture Center (NWAC), says the goal was to test and further develop a novel incubator for use in commercial channel catfish hatcheries.
