Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a culture pond for shrimp larvae cultivation. Background Technology

[0002] Shrimp larvae are nauplii, which are divided into healthy larvae and sub-healthy larvae. Healthy larvae: bristles and caudal spines are developed normally and are straight, appendages are undamaged, larvae are robust, phototaxis is strong, and they are active in the middle and upper layers of the water. Sub-healthy larvae: bristles and caudal spines are obviously bent, atrophied or broken, or incomplete, larvae are small, phototaxis is weak, and they sink to the lower layer or bottom of the water. Oxygenation and water flow stimulation are necessary during the shrimp larvae cultivation process. However, in current cultivation environments or conditions, water flow stimulation is only achieved through the inlet and outlet. This method easily washes shrimp larvae out of the drain pipe, causing mass mortality. Furthermore, it is difficult to control the water flow balance within the cultivation pond, which is not conducive to stimulating the shrimp larvae with water flow. In traditional cultivation ponds, due to poor waste collection, uneaten feed, feces, and other organic matter cannot be discharged from the aquaculture water in a timely manner. This leads to an endless increase in oxygen-consuming factors such as "water respiration" and "bottom respiration," resulting in an increased "oxygen debt," a decrease in oxidation-reduction potential, and an increase in the concentration of reduced toxic substances (ammonia nitrogen, nitrite nitrogen, hydrogen sulfide, low-valence metal ions, etc.). The proliferation of harmful pathogenic microorganisms also increases, severely impacting the healthy growth of shrimp larvae. Utility Model Content

The side wall of the culture basket 2 is provided with several water passage holes 13, and the water inlet pipe 5 is located on the upper side wall of the culture pond 1.

[0022] This invention relates to a cultivation pond for shrimp larvae. Shrimp larvae are placed into cultivation baskets 2 at a certain density, while juvenile shrimp can be placed in cultivation pond 1 for simultaneous co-culture. This promotes stress regulation for both shrimp larvae and juvenile shrimp. Water is injected into the pond through inlet pipe 5, maintaining a balanced water flow between cultivation baskets 2 and cultivation pond 1. During cultivation, a rotary motor 9 rotates cultivation baskets 2, creating clockwise or counterclockwise water flow between cultivation pond 1 and cultivation baskets 2. This provides water regulation for both shrimp larvae and juvenile shrimp. The water flow stimulates the growth of shrimp larvae and also draws uneaten feed, feces, or damaged shrimp from the rearing process into a concave area at the bottom of the rearing pond 1, where it is collected. A drain pipe 10 is located in this concave area, and a filter screen 11 connects the drain pipe 10 to the rearing pond 1. The filter screen 11 prevents juvenile shrimp from entering the drain pipe 10, while impurities accumulate there. By opening the control valve 12, these impurities are removed from the drain pipe 10, effectively improving the rearing pond 1's waste collection and discharge capacity. When the rearing pond 1 needs water changing or the rearing pond 1 and rearing baskets 2 need cleaning, the staff activates the electric lifting rod 4 to raise and remove the rearing baskets 2. This allows for the harvesting of shrimp larvae and manual cleaning of the rearing baskets 2 and the interior of the rearing pond 1, which is beneficial for subsequent shrimp larvae rearing and provides a better rearing environment for the shrimp.

[0023] Specifically, the bottom surface of the cultivation basket 2 is provided with multiple layers of filter plates 14, and flow holes 15 are interspersed between the filter plates 14. During the rotation of the cultivation basket 2 or natural cultivation, the feed powder and feces produced by the shrimp larvae in the cultivation basket 2 are also collected on the bottom surface of the cultivation basket 2. Through the multiple layers of filter plates 14 and flow holes 15, the shrimp larvae can be prevented from being filtered into the cultivation pond 1, while the flow holes 15 can allow the feed powder and feces to flow into the cultivation pond 1, and then be collected in the depression on the ground for collection and sewage discharge.

[0024] Specifically, the side wall of the culture basket 2 is provided with several first fan blades 16; when the culture basket 2 rotates, the first fan blades 16 stir the water flow in the culture tank 1, promote water flow, and help cultivate juvenile shrimp.

[0025] Specifically, the outer wall of the shaft 8 is provided with several second fan blades 17; when the shaft 8 drives the culture basket 2 to rotate, it will simultaneously drive the second fan blades 17 to rotate, promote the water flow in the culture basket 2, further stimulate the shrimp larvae with water flow, and improve the shrimp larvae's immunity and stress resistance.

[0026] Specifically, the lower end of the culture tank 1 is provided with a support foot 18, the bottom end of which is connected to the bottom surface of the base of the support frame 3. The support foot 18 can support the culture tank 1 and ensure the stability of the culture tank 1.

[0027] Specifically, a collection box 19 is provided below the sewage pipe 10. The collection box 19 is set on the base of the support frame 3. The collection box 19 can collect feces, bait and shrimp molting residue in the sewage pipe 10.
