The feed for breeding crabs generally accounts for more than 30% of the cost of feeding. Due to the current high cost of crab feed, the price of commercial crabs has dropped, and the income of crab farmers has been getting lower and lower. This has seriously dampened the enthusiasm for raising crabs. In recent years, some aquaculture departments and specialized crab raising households in Binhai County, Jiangsu Province have successfully researched and developed potato and crab feeds through research and exploration and under the guidance of relevant experts. Practice has proved that the use of potatoes cooked, processed into crab feed, can not only greatly reduce the cost of crabs, improve the efficiency of crabs, but also solve the problem of local potato sales, so that every 500 grams of potatoes than the past value of 0.2 yuan .
The use of potatoes to make crab feed has a wide range of raw materials, low cost, good palatability, nutrient-rich, crab-like food, and can be used for feeding fish, shrimp and other aquatic products. At the same time, the feed production method is relatively simple, and it can be produced on a large scale by machinery, and the crab owners can also make it by themselves. Therefore, the potato crab feed has a wide range of application values.
The technical points of its processing and feeding are introduced as follows.
First, the process
Material selection - cleaning - cut - cooking - crushing - batching - forming - drying.
Second, processing technology
1. Choose raw materials without pests, germination, and moldy potatoes. Spring potatoes have high nutrient content, and spring harvested potatoes are generally preferred.
2. Cleaning Remove the potato skins mechanically or manually and clean the peeled potatoes with water.
3. Cut through the appropriate cut, so that the size of the same potatoes, in order to facilitate cooking cooked at the same time.
4. Cooking The potatoes are cooked until they mature in stainless steel, aluminum pans or steamers and then ceased to cool.
5. After crushing and cooling, potatoes are picked up from the pot in a timely manner and broken by mechanical or manual stirring. After crushing, it is usually a paste or thick paste.
6. Ingredients to increase palatability, improve nutrients, can be added after the crushing amount of edible salt, flavor, vitamin C and ferulic and so on. Each 100 kilograms of potatoes were added in amounts of 100 grams of salt, 50 grams of flavor, 100 grams of ferula, and 200 grams of vitamin C. Stir in the mixture immediately after adding it.
7. Molding is done mechanically or manually to make small cubes or granules of suitable size.
8. Dry it in time to dry or dry it, then seal it in a plastic bag and store it.
Third, feeding method
The requirements for feeding crabs with potato and crab diets are as follows: crabs are used 2 to 3 times a day, young crabs are used once to twice a day, and each time they are fed again after the last meal. The bait should be put in a clean place and it is best to set it on the feeding table. Feeding fish, shrimp, etc. can be performed with reference to conventional methods.
