Description

Monitoring ship for lobster breeding

Technical Field

The utility model belongs to breed the control field, concretely relates to monitoring ship is bred to lobster.

Background

The shrimp pond for culturing the lobsters, particularly the pond bottom, is easy to generate an anoxic phenomenon. In the existing culture oxygen supply technology, the oxygen supply technology for lobster culture is limited, the oxygen supply method is unscientific, and the oxygen supply equipment is complex to operate, so that the growth speed of the crayfish is slow, and the quality of the crayfish is poor.

In lobster cultivation, water quality management is very important, and management of water quality dissolved oxygen is the central link. The dissolved oxygen of the aquaculture water body is generally kept between 3 and 8 mg/L, at least above 3 mg/L. When the crayfish is slightly anoxic, the crayfish is dysphoria, the breathing is accelerated, most of the crayfish concentrates on the surface layer activity of water, the crayfish individually floats, and the growth and the breathing of the crayfish are seriously influenced by long-term hypoxia; when the crayfish is seriously anoxic, a large number of crayfish can float, swim and are powerless, even sink and die by suffocation. Therefore, increasing dissolved oxygen is very important for the whole crayfish breeding system.

The pH value of the culture water body of the crayfishes is kept to be as low as 7.5-8.5 as possible so as to be beneficial to the normal growth and development of the crayfishes. When the PH value is less than 6.5, the water quality is too high in acidity; when the pH value is more than 9.5, the water quality is required to be regulated and controlled when the alkalinity of the water quality is too high. When the water level is too deep, the crawling ability of the crayfishes is not in direct proportion to the depth of the pond water, and the crayfishes are in the deep water area for a long time, cannot normally exchange breathing oxygen and die. In spring, the water depth is generally kept between 0.6 and 1 meter, and shallow water is favorable for growth of aquatic weeds and shelling of shrimp seedlings; in summer, when the water temperature is higher, the water depth is controlled to be 1-1.5 meters, which is beneficial for crayfishes to spend high-temperature seasons; in winter, the water level does not need to be very deep, generally speaking, the water level of the circular trench is controlled to be about 80-120 centimeters, the water level of the terrace is kept to be about 30-40 centimeters, the water level required by aquatic weed planting and normal growth can be maintained, a certain water body temperature can be kept, the soil around the pond or the rice field can be moistened, and the hole digging of lobsters is facilitated. After spring, the water level is gradually increased along with the rising of the climate.

Crayfish breeding needs to be maintained within a reasonable density range. If the crayfish is bred at an excessive density, the environment of the crayfish growth activity is deteriorated, a density emergency effect is induced, the groups are gathered together, the fighting and killing phenomena are bound to occur, and the excessive density is one of the key reasons for the short-term death of the crayfish in recent years.

At present, the main oxygenation devices for aquaculture in the market are water wheel type, impeller type, water spraying type and the like, and generally have low oxygenation efficiency and poor oxygenation effect.
