AI Technical Summary

Benefits of technology

This patented technology uses small floating objects called seaweeds (a type of green plant) suspended from an artificial structure made up mostly of polystyrene beams or other materials like wood rods). These tiny plants help protect against harmful ultraviolet rays while still allowing light into the liquid inside them through reflection. They also provide space between it's cells without blocking any parts of its surface. By adding these structures alongside the culturing process they can create more stable environments where fish grow well with less energy than traditional methods. Overall, this innovation helps improve the quality and yield of oceanic crops by reducing their shading on land during production.

Problems solved by technology

This patented describes various methods for controlling unwanted plants called seaweeds by killing off these vegetations during winter periods while maintaining proper nutrition levels within an enclosed area where they live. These techniques involve treatments involving adding chemical agents into the environment near the sewalls containing the sea weeds. However, this treatment may result in environmental pollution if released through leaching out underground waters. Additionally, some species of marine organisms cannot tolerate high concentrations of certain metals found naturally in saltwater environments because they require specific mineral substances. Therefore, new ways must be developed to control these types of microscopically growing plantings effectively.

Embodiment 1

[0011] In the following, a 70-meter×50-meter culture pond, with ginseng and shrimp polyculture and bottom-seeded shellfish as an example, illustrates the prevention and control methods of moss in a marine culture pond.

[0012] The aquaculture pond is east-west, with an inlet gate on one end and an outlet gate on the other side. The water holding depth in the pond is maintained at 1.5 meters. The salinity is 25‰ and the ammonia nitrogen content is 30Vmol / l. The pH is 7.8.

[0013] At the two ends of the breeding pond, 42 wooden stakes were arranged in sequence along the direction of the water flow perpendicular to the water body in the pond at an interval of 2.5 meters, and then 21 fixed ropes were connected in parallel between the corresponding wooden stakes on both sides. The fixed rope is a polyethylene rope.

[0014] Tie 35 floats on the rope body of each fixed rope at a distance of 2 meters, and fasten multiple seedling ropes at a distance of 1.5 meters between two adjacent f...

Embodiment 2

[0020] In the following, another 80m×40m aquaculture pond is taken as an example of ginseng and shrimp polyculture to illustrate the prevention and control methods of moss in marine aquaculture ponds.

[0021] The aquaculture pond is an intertidal holding pond with inlet and outlet gates. The water is changed every month between the tides. The water holding depth in the pond is kept at 1.6 meters. The salinity is 32‰ and the ammonia nitrogen content is tested. 40Vmol / l, pH value is 8.3.

[0022] The bottom of the culture pond is relatively hard, so 34 stone mounds are placed on the bottom of the pond at a distance of 2.5 meters at a distance of 2.5 meters at the two ends of the pond, and then connected in parallel between the corresponding stone mounds on both sides. 17 fixed ropes. The fixed rope is a polyethylene rope.

[0023] It should be noted that the stone mound used for fixing can also be replaced by an iron anchor.

[0024] Tie 40 floats on the rope body of each fixed rop...

Abstract

The invention relates to a method for controlling lichen in a marine culture pond, which is characterized in that: more than two fixed boom cables are arranged horizontally in the culture pond along the flow direction of the water in the culture pond; two ends of each of the two fixed boom cables are fixed with the bottom of the pond through fixtures; a plurality of buoys are fixed on the bodies of the fixed boom cables between two fixed ends; a plurality of strands of seedling rope are tied between the two adjacent fixed boom cables; and alga seedlings which are gracilaria seedlings or sargasso seedlings are clamped between the strands of the seedling ropes. The marine large algae cultured in a hanging manner can shade sunlight, improve the physical and chemical indexes of the pond, provide a comfort water temperature and good growth environment for cultured varieties, effectively suppress the growth of the lichen and reduce culture cost. The method is reasonable, low in cost, simple and feasible in operation, allows the aquatic products to growth quickly, and achieves a high survival rate of the aquatic products.
