Description

Technical Field

[0001] This utility model relates to the field of shrimp fry farming technology, and in particular to a shrimp fry density control device for shrimp fry farming ponds. Background Technology

[0002] Shrimp larvae rearing ponds are facilities specifically designed for raising shrimp larvae. They provide a suitable growth environment for the larvae until they are large enough to be transferred to larger rearing ponds or natural environments. Here are some key points regarding shrimp larvae rearing ponds: Water quality management: Maintain clean water quality and regularly test water parameters such as pH, dissolved oxygen, ammonia nitrogen, and nitrite. Maintain stable water quality through methods such as aeration, filtration, and biological purification.

[0003] Density control in shrimp larvae rearing ponds is one of the key factors in ensuring the healthy growth and improving the survival rate of shrimp larvae. Here are some suggestions regarding density control in shrimp larvae rearing ponds: Suitable Density: The appropriate stocking density should be determined based on the species and size of the shrimp larvae, rearing conditions, and the facilities of the rearing pond. Generally speaking, the density can be slightly higher when the shrimp larvae are small, and gradually reduced as they grow.

[0004] Feeding: Adjust the feeding amount according to the shrimp larvae density to ensure that each shrimp receives enough feed, avoiding fighting and uneven growth due to insufficient feed. Growth Monitoring: Regularly monitor the growth of the shrimp larvae and adjust the density according to the growth rate and health status. Slow growth or health problems may be signs of overcrowding. Separate Pond Culture: Once the shrimp larvae have grown to a certain size, they can be separated into different ponds to reduce the density and provide more space for growth.

[0005] However, relying on manual control during the shrimp larvae density control process cannot achieve efficient and accurate screening. Therefore, we propose a shrimp larvae density control device for shrimp larvae rearing ponds. Utility Model Content

In addition, the entire culture box can be lifted out of the water for weighing, thereby controlling the density of shrimp larvae. Furthermore, the growth depth can be adjusted according to the growth needs of different sizes of shrimp larvae.

[0017] (III) Beneficial Effects

[0018] Multiple sets of separate exhaust systems enhance the uniformity of oxygen in the water, meeting the requirements of this deep-well structured aquaculture. After feed mixing, a pressurized feed-water mixture is introduced into pipes via a pressurization device. Several feed outlets are located on the sides of the pipes, allowing the material to be fed into the aquaculture wells for shrimp larvae. When placing the aquaculture box, the clearance opening is staggered from the support frame, which supports the box. When removing or placing the box, the clearance opening is aligned with the support frame, allowing for easy lifting and lowering of the box. Multiple aquaculture boxes can be stacked. A permeable mesh is installed on the outer side of the box, facilitating oxygen and feed exchange with the water flow in the aquaculture well. The entire box can be lifted out of the water for weighing, controlling shrimp larvae density and allowing for adjustments to the growth depth based on the size and growth needs of different shrimp larvae.
