Embodiment Construction

[0013] 1. Clean the pond: choose a pond with 10 mu of sea water and shoal, and dry the pond after the shrimps come out in winter, and remove 10-20 cm of silt on the surface of the pond bottom;

[0014] 2. Bubble pool: Enter the water bubble pool in mid-February, and carry out biological agent disinfection;

[0015] 3. Water intake: put water into the pond in mid-March, and the water depth is required to be 1.2 to 1.5 meters;

[0016] 4. Fertilizer and water: use 10 catties of diammonium phosphate to fertilize and water after entering the water, and use photosynthetic bacteria and seaweed to reproduce to form biological bait. The salinity is controlled at 20‰-30‰, and the pH value is 7-8.6;

[0017] 5. Release seedlings: Release 500,000 razor clam seedlings in mid-February; release 50,000 Chinese prawn (or Penaeus monodon) seedlings from April 20 to May 10; release 20,000 portunus seedlings in mid-May;

[0018] 6. Feeding management: After releasing the seedlings, use the feed...

Abstract

The invention discloses three-dimensional cultivation technology for a seawater shoal pond, which is characterized by comprising the following steps: drying the pond after shrimps are produced in winter, and removing 10 to 20 centimeters of silt on the bottom surface of the pond; feeding water to soak the pond in the middle of February, and meanwhile performing biological agent sterilization; feeding water into the pond until the depth of water is 1.2 to 1.5 meters in the middle of March; fertilizing 1 kilogram of diammonium phosphate to water in each mu, propagating photosynthetic bacteria and seaweed to form biological baits, and controlling the salinity to between 2 to 3 percent and the pH value to between 7 and 8.6; putting seedlings of sinonovacula constricta in the middle of February, seedlings of penaeus chinesis or Japanese penaeus monodon between April 20 and May 10 and seedlings of swimming crabs in the middle of May; and enriching the water once in the middle of each month in a mode of feeding fresh small conches serving as the main baits and fish and shrimps serving as the auxiliary baits, and performing little water exchange every ten days. The technology solves the problems of single variety, low yield and poor benefit of the current seawater shoal pond cultivation, and is suitable for three-dimensional cultivation for the sinonovacula constricta, the swimming crabs, the penaeus chinesis or the Japanese penaeus monodon in the seawater shoal pond.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a three-dimensional culture technique in seawater shallow ponds with constricted razor clams, swimming crabs, Chinese prawns or Japanese monodon prawns. Background technique [0002] At present, in seawater shoal pond culture, a single seafood is mainly cultured. This culture method has problems such as single species, low output, and poor efficiency. Contents of the invention [0003] The present invention aims to solve the problems of single species, low output and poor benefit in seawater shoal ponds at present, and invents a three-dimensional culture technology in seawater shoal ponds with razor clams, portunus, Chinese prawns or Japanese monodon [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a three-dimensional breeding technology in seawater shallows and ponds, which is special in that it includes th...
