1, carbohydrate food carbohydrate is one of the necessary energy sources for small crabs, mainly containing starch, glucose, xylose and other ingredients. Small crabs can use these carbohydrates to provide energy for their growth and metabolism, and promote their growth and development.
Usually, the feed of small crabs contains a certain proportion of starch ingredients, such as koi fish feed and red corn, which can provide enough carbohydrates for small crabs.
2. protein food protein is an important nutrient for the growth and development of small crabs, which can promote the muscle development and tissue repair of small crabs. The main sources of protein are fish meal, shrimp meal and soybean meal, among which fish meal, shrimp meal and other aquatic products have higher protein content, which is more suitable for the growth needs of small crabs.
It should be noted that excessive protein will increase the waste discharge of small crabs, thus causing water pollution, so it should be added appropriately.
3, vitamin foods Small crabs need to absorb rich vitamins to maintain good health. Vitamin B and vitamin C are two essential vitamin components of small crabs, which can promote their metabolism, enhance their immunity, promote the synthesis of collagen and improve their body resistance.
The main sources of vitamin foods are all kinds of green vegetables and fruits, such as spinach, celery, mushrooms, potatoes, lemons, apples, etc., which can provide the necessary vitamins for small crabs.
4, mineral foods Small crabs also need to absorb the right amount of minerals, such as calcium, phosphorus, potassium, etc. during their growth to help the formation of bones. The main sources of minerals are fish meal, astaxanthin, seaweed powder, fish scales, etc. Among them, the source of calcium is seaweed. Supplementing appropriate minerals can improve the disease resistance and adaptability of small crabs.
5. Other precautions When providing small crab food, you should pay attention to the following points:
1, ensure that the food is fresh and not contaminated.
2. Control the feeding amount and frequency, and excessive feeding will cause the water quality to deteriorate.
3. Increasing the variety of feed and diversified food can make the food collected by the crab more abundant.
The above are the edible things needed for small crab culture, and I hope I can help you.
