High-efficient culture method for prawns

Abstract

The invention discloses a high-efficient culture method for prawns. The method comprises the following steps: before putting young prawns, sufficiently sunning a pond and carrying out disinfection, then filtering water sources, fertilizing water, and diluting fertilized water when the young prawns are placed; when the young prawns are put, pouring powerful effective microorganisms (EM) and beneficial bacteria prawn protecting drugs, wherein the use amounts of EM and the beneficial bacteria prawn protecting drugs are 1 kilogram per mu (a unit of area equal to 0.0667 hectares); while managing young prawns, feeding powdered high nutrient feeds three times a day at regular hours and in fixed quantities, and observing materials on a material platform and lengths of the prawns; during culture of the prawns, within the first month after the prawns are thrown, changing water every five days, wherein 5-10 cm deep water is changed each time, within the first to third months after the prawns are thrown, changing water every seven days, wherein 10-20 cm deep water is changed each time, and starting a waterwheel aerator everyday, wherein the waterwheel aerator operates for 4 to 5 hours in rainy days and 2 to 3 hours in sunny days. Compared with the prior art, the prawns are fed by the powdered high nutrient feeds, thereby being capable of effectively improving the growth and enhancing the immune function of Penaeus monodon to shorten the growth periods of the prawns so as to improve the culture efficiency.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for efficiently cultivating prawns. Background technique [0002] Prawns, scientific name Oriental prawns, also known as Chinese prawns and tiger prawns. Arthropoda, Crustacea, Decapod, Shrimpidae, Penaeus. Prawns are large in size and are commonly known as prawns. During the growth process, prawns have to go through dozens of molts, and every time they molt, they will get a larger growth; molting is an important symbol of the growth of prawns, which is directly affected by the external environmental conditions. Shrimp is named after the fishermen used to calculate the sales of "one pair" products in history. It is distributed in shallow coastal waters with a sea water temperature above 20°C. Prawns are sea prawns, which are a unique specialty in my country. There is artificial breeding for export to earn foreign exchange. However, due to changes in water quality, ...

Shrimp is named after the fishermen used to calculate the sales of "one pair" products in history. It is distributed in shallow coastal waters with a sea water temperature above 20°C. Prawns are sea prawns, which are a unique specialty in my country. Export earns foreign exchange, and there is artificial breeding, but due to changes in water quality, the ability to dissolve oxygen in the water body decreases, and extreme weather occurs frequently and lasts for a long time, making it increasingly difficult to raise prawns
