Detailed Description
Example 1
The invention relates to a method for breeding macrobrachium nipponensis in freshwater shrimps, which comprises the following breeding steps: firstly, draining water in a prawn pond, and then naturally drying pond sludge at the bottom of the pond. Step two, introducing clear water to ensure that hydrilla verticillata is planted in the whole pond area after the pond sludge is wetted. And step three, continuously introducing clear water one meter deep after the hydrilla verticillata is planted. And step four, allowing the hydrilla verticillata to naturally grow for seven days. And fifthly, sprinkling 30 jin of crude salt to the whole pond according to the water depth of 1 m per mu. And sixthly, putting the shrimp seeds into the shrimp pond. Seventhly, sprinkling 3 jin of tea seeds according to the depth of 1 meter per mu in the whole pond seven days after the shrimp larvae are placed. Step eight, feeding the feed once in the morning and evening every day for feeding, wherein each month is a period, the step six is circulated until the middle growth stage of the shrimp fries is finished, the general culture period of the shrimps is six months or eight months, the six months are two months respectively at the first, middle and late stages, the eight months are two months only at the initial stage, and the middle and late stages are three months. And ninthly, increasing oxygen in the shrimp pond for not less than fifteen hours every day. Step ten, when the feed is put in the morning and evening every day, the water temperature is not lower than eighteen degrees and not higher than thirty-eight degrees.
The naturally dried pond sludge refers to that the pond sludge can retain 20 percent of water at most within 10cm of depth.
The clear water refers to running water or standing water with the visibility reaching 80% at the depth of 2 meters between mountains. The coarse salt splashing of the whole pond is to directly and uniformly sprinkle coarse salt particles in the whole pond or sprinkle salt water in the whole pond according to the proportion that 1 jin of salt is dissolved in 100 jin of water, and the shrimp seeds are released after 6 hours after the coarse salt sprinkling. The splashed tea seeds are tea seed meat particles which are obtained by squeezing tea seed oil, and the mesh number of the particles is ten meshes.
When the hydrilla verticillata is planted in the whole pond area, the front and back spacing distances between two adjacent hydrilla verticillata are respectively 30 cm, and the left and right spacing distances are respectively 50 cm. The hydrilla verticillata is trimmed once every two months after being planted, and clear visible gaps are trimmed in an array of one meter before and after the hydrilla verticillata is flourishing.
The time for feeding the feed twice in the morning and at the evening is 7-8 am, 17-18 pm and 19-20 pm in the summer season. The mode of feeding the shrimps is as follows: feeding the feed to the pond edge, and feeding the feed by walking a circle by using the boat-swimming pond edge. The feed is put in the position of one meter farthest from several surfaces as far as possible. Because the shrimp are reptiles, freshwater shrimps are reptiles, unlike the eight generations of shrimp, which are swim and bounce animals, they are not the same as whole shrimp. The macrobrachium nipponensis is used for searching food in a creeping mode from the pond, so that the macrobrachium nipponensis is thrown into the pond to be fed.
Example 2
The same as example 1, except that: after planting the hydrilla verticillata, continuously introducing clear water to a little bit five meters deep, allowing the hydrilla verticillata to naturally grow for eight days and a half, then sprinkling 40 jin of crude salt to the whole pond according to the water depth of 1 meter per mu, putting the shrimp seeds after 15 hours, and sprinkling 4 jin of tea seeds to the whole pond according to the depth of 1 meter per mu after seven days.
Example 3
The same as example 1, except that: and (2) continuously introducing clear water to a depth of two meters after the hydrilla verticillata is planted, allowing the hydrilla verticillata to naturally grow for ten days, then sprinkling 50 jin of crude salt to the whole pond according to the water depth of 1 meter per mu, putting the shrimp seeds after 24 hours of sprinkling the crude salt, and sprinkling 5 jin of tea seeds to the whole pond according to the depth of 1 meter per mu after seven days of putting the shrimp seeds.
