1.water source and water quality.
Water is the primary condition for fish farming, sufficient water source, good water quality, high oxygen solution, no excess toxic substances, plus pond injection and convenient drainage, such a pond is conducive to intensive raising, improve the water fish load and fish yield.

2.area.
The requirement of area size is appropriate to meet the needs of fish ecology and growth. The area is large, and the wind surface is also large, which is easy to form a wave on the water surface, dissolve the oxygen in the air into the water, increase the oxygen dissolved in the water and promote the pool water up and down to the convection.

3.water depth.
The fishing proverb says: "An inch of water, an inch of fish" , reflects the relationship between water depth, fish growth and fish yield. Having the necessary water depth is an important condition for seizing the high yield. Net production per unit area increases with increased water depth. The water depth of the pond is 1.7 ~ 2 m, increasing 100 kg per 667 m 2 than 1.2 ~ 1.5 m, the water depth is 2 ~ 2.5 m, and 150 kg per 667 m 2. The depth of pool water is generally 2.5 ~ 3 meters.

4.pool shape
pool slope pool shape is rectangular, the ratio of length and width is appropriate: 2: 1 or 5: 3, so as to facilitate feeding, catching operation and catching mesh specification, and can save labor. The direction of the pool can be based on the terrain and local wind direction, generally north and south. The ridge surface of the pond is 4 ~ 6 meters wide, the central ridge surface is 8 meters wide, and the areas with more land can also be appropriately relaxed. The slope of the pond is good 1: 2.5 or 1: 3
