Embodiment 1
[0020] A kind of culture method of crayfish, it is characterized in that: comprise the following steps, 1) the selection of culture pool: the pond depth of crayfish culture pool is selected 1.2-1.5m, and the anti-escape net is set around the culture pool, on both sides of the bottom of the pool Set the water inlet and the water outlet respectively, and set the anti-escape nets on the water inlet and the water outlet respectively;
[0021] 2) Treatment of aquaculture ponds before breeding: desilting, flushing and disinfection of the aquaculture ponds;
[0022] 3) Sprinkle 0.5 kg of farmyard manure per square meter at the bottom of the breeding pond;
[0023] 4) Plant aquatic plants at the bottom of the culture pond in step 3, cultivate algae in the water after the culture pond enters the water, and make the coverage area of the algae be more than 70% of the culture pond; the temperature of the water in the culture pond is 28 degrees Celsius, and the water body The pH value i...

The invention discloses a culture method of crawfishes. The culture method comprises the following steps: 1) selecting a culture pond; 2) treating the culture pond before culture; 3) spreading 0.5kg of farmyard manure to every square meter of the bottom of the culture pond; 4) planting aquatic weeds at the bottom of the culture pond of the step 3, culturing algae in water after the culture pond is filled with water, and enabling the coverage area of the algae to be 70% or more of the internal area of the culture pond; 5) putting young crawfishes into the culture pond; 6) putting a feed into the culture pond and performing later-period management; and 7) putting a nitrogen fertilizer or a mixed fertilizer into the culture pond 30 days after putting the young crawfishes, 25-50kg per mu, wherein when the nitrogen fertilizer or the mixed fertilizer is put into the culture pond, the nitrogen fertilizer or the mixed fertilizer is sealed by using a plastic film and is put into a woven bag, and the woven bag and the plastic film are punctured by using a chopstick to have 1-10 holes in the size of the chopstick. The crawfishes cultured by the culture method disclosed by the invention are good in health, and the feed put into the culture pond is good.
Description
technical field [0001] The invention relates to a water body cultivation method, in particular to a crayfish cultivation method. Background technique [0002] The nutrition of crayfish is well known. At present, crayfish farming is developing rapidly in our country. During the growth process of crayfish, crayfish are susceptible to diseases due to a large amount of feed. Feed, causing the physical decline of crayfish, but also reduces the economic benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a crayfish culture method that can improve the crayfish's physique and reduce feed input. [0004] In order to solve the above-mentioned technical problems, the technical solution proposed by the present invention is: a method for cultivating crayfish, comprising the following steps, 1) selection of the cultivation pond: the depth of the pond for the cultivation of ...
