Introduction to the Biological Characteristics of the Topmouth Culter (Culter alburnus) from the Yangtze River
The topmouth culter, commonly known in Guangdong as "Yangtze Heshun," in the middle reaches of the Yangtze as "qiaobai" or "white fish," and in the lower reaches of the Yangtze as "Taihu white fish." In recent years, many people in our province have passed off the bigeye culter, i.e. the "Pearl River Heshun," as "Yangtze Heshun" to sell to farmers, with the result that even after four years of intensive culture they could not reach the market size of 8 liang to 1 jin. Since last year, Hainan culter and qingshao culter have been passed off as "Yangtze Heshun"; although they grow somewhat faster than the bigeye culter, they are slower than the genuine topmouth culter, and it is very difficult to raise them to a market size of over 1 kg

What do river eels eat? A detailed explanation of the taming and feeding method
River eels are carnivorous fish. Generally speaking, river eels feed on mussels, shellfish, clams, fish, shrimp, and animal carcasses. In artificial rearing, formulated feed can be provided, but the protein content must be above 45%. River eels are nocturnal animals and mainly forage for small natural animals. In artificial rearing, the stocking density is high, and natural bait alone cannot meet their needs, so artificial feed must be provided as a supplement. When artificial feed is first introduced, river eels are not accustomed to it and do not come to eat, so a "taming and feeding" stage is necessary to get them used to eating artificial feed and to develop the habit of feeding at fixed times and fixed locations.

Hybrid late japonica rice restorer lines successfully bred in the Yangtze River Basin
Through the efforts of experts from the Shanghai Academy of Agricultural Sciences, the "Yangtze River Basin hybrid late japonica rice restorer lines - Shenhui 254 and Shenhui No. 1" were successfully bred and utilized. This project was awarded first prize for scientific and technological progress by the Shanghai Municipal Government this year. The key to applying hybrid late japonica rice in production in the Yangtze River Basin is to breed excellent late japonica-type restorer lines. This project used intermediate materials between indica and japonica subspecies as bridge parents, introduced indica restorer genes into late japonica rice varieties, adopted convergent crossing and systematic selection, and gathered the excellent base
