Shrimp culturing method

Abstract

The invention discloses a shrimp culturing method. The shrimp culturing method comprises the following steps that (1) an aquaculture pond is prepared according to a conventional culturing method, and shrimp seeds are thrown into the aquaculture pond according to a conventional density; (2) 10 kilograms to 20 kilograms of bioflocculation provenance is poured into each mu every day when the ages of the shrimps are smaller than one month, and 20 kilograms to 30 kilograms of bioflocculation provenance is poured into each mu every day when the ages of the shrimps are larger than one month; (3) a water bottom aeration machine is used for oxygenation in the whole culturing process. The method for preparing the bioflocculation provenance comprises the steps that brown sugar, rice bran and feed additives are evenly mixed and then are added to clean fresh water to be evenly stirred, sealing is conducted, fermentation is conducted for three to four days at the temperature of 25-32 DEG C, and then the bioflocculation provenance is obtained, wherein the weight ratio of the clean fresh water, to the brown sugar, to the rice bran and to the feed additives is 250:5-8:30-40:2-3. By the adoption of the shrimp culturing method, the feed coefficient of shrimp culturing ranges from 0.7 to 0.8; compared with traditional culturing feed, the growing period of the shrimps cultured according to the method is shortened by 15 days to 20 days under the condition that the adult shrimps are obtained.

Description

technical field [0001] The invention relates to a method for cultivating prawns, which belongs to the technical field of seawater cultivation. Background technique [0002] In marine aquaculture, the added value of aquaculture prawns is relatively large, but the risk of aquaculture is also relatively large, because the aquaculture environment, feeding feed and feeding methods of prawns are very easy to affect the prawns during the aquaculture process. growth, resulting in high cost of breeding. At present, the conventional farming method of prawns is nothing more than feeding feed, changing water regularly, and maintaining a water environment suitable for the growth of prawns. This mode of farming is a traditional farming method. The feed coefficient of this farming method is relatively high, only 20% to 30% of the fed protein is converted into shrimp food, most of which cannot be utilized and exist in the culture water body, so the feed coefficient of the traditional sea s...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the high feed coefficient in the existing prawn cultivation method, which cannot make full use of the organic matter and residual bait in the cultivation environment, and the high cost. , a shrimp farming method that makes full use of organic matter in the farming environment
