Techniques for rearing summer fry fish: stock one main fish species, do not introduce carp, and combine feed with fertiliser for intensive feeding
Summer fry fish are small and delicate, with a weak ability to withstand adverse environments. In addition, at this stage the summer fry undergo a dietary transition, and their digestive system structure and function are not yet fully developed, so their digestive capacity is poor. If rearing methods are improper, mass mortality will occur. Through experiments, the author found that adopting the following rearing methods can significantly increase the survival rate and rearing efficiency of summer fry. Scientific stocking and rational matching: the traditional rearing method is mainly polyculture of multiple species. However, from production practice, because fish have different feeding habits, this kind of rearing

Techniques for large-scale rearing of bream summer fry, suitable for triangular bream and blunt snout bream
Bream (triangular bream, blunt snout bream) are high-quality freshwater fish. They are not only excellent species for pond culture but also suitable for stocking in large water bodies, where their tendency to readily form natural populations can be used to achieve resource protection and enhancement. The techniques for large-scale rearing of bream summer fry are described below: 1. Conditions of the summer fry rearing pond. The summer fry rearing pond requires an abundant water source, unpolluted water quality, and convenient filling and drainage. The area should not be too large, generally 1-3 mu, with a water depth of 1-1.2 m being suitable. The pond must not leak,
