IV. Feeding methods for freshwater shrimp

1. According to the nutritional needs of freshwater shrimp at the same growth stage, the feed combination and feeding should be done well. Freshwater shrimp juvenile and juvenile stages feed on rotifers, cladocerans, copepods, and aquatic insect larvae, while the adult shrimp stage eats both animal and plant feeds. After shrimp seedlings and shrimp seeds are stocked, appropriate top-dressing fertilizer is required to improve the water quality.

During the rapid growth stage of freshwater shrimp from August to October, feed more bran, bean cake and green feed, and appropriately feed animal feed. From November to December, freshwater shrimps are mainly fed animal feed before overwintering.

2. Feed freshwater shrimp according to their living habits and feeding characteristics. Freshwater shrimps mostly look for food at night and have the habit of competing for food and being gluttonous. Feeding should be done once in the morning and once in the afternoon every day, mainly in the afternoon, accounting for 70% of the whole day's feeding; adopt a qualitative, quantitative, and timed feeding method, feed enough and evenly to ensure that every shrimp is eaten Be full and avoid fighting with each other for food.

3. Feed reasonably according to weather, water quality changes and shrimp activity and feeding conditions. The suitable water temperature for freshwater shrimp growth is 20 to 32°C. From August to October, freshwater shrimp eat a lot of food. The daily feeding amount can be arranged according to 6 to 10% of the body weight of the shrimp in the pond, and the dry feed or compound feed can be adjusted according to 2 to 4%. The daily feeding amount should be adjusted according to the weather, water quality conditions and shrimp activity. Increase or decrease as appropriate.

In continuous rainy weather or the water quality is too thick, you can feed less, and when the weather is fine, feed more; feed less when a large number of shrimps are molting, and feed more after molting; feed less during the season when shrimps are sick. , feed more when growth is normal. In order to ensure that shrimps are well fed, it is also necessary to reduce waste and improve feed utilization.
