ABSTRACT
The major fish fry producing areas in China are located in the Yangtze and Pearl valleys. Three major tributaries to the Yangtze River produce large numbers of fry. These are the Han, the Hsaing, and the Kan rivers. Most of the collecting gear used in China consists of setnets. The most prevalent gear used in the Yangtze River is the trap. There are two major kinds: the floating trap and the fixed trap. Both traps are similar in structure. Fish fry are called various different names by people from different localities. Generally there are two main kinds of fry: culturing fry and pest fry. Fish fry that are caught in the river contain not only the culture species, but also many other nonculture species. Control of these nonculture species is a very important undertaking in fish culture business. There are many methods of pest control, the best of which are the sieve method and the squeeze method.
