Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture, in particular to a fish gathering and breeding type artificial fish reef. BACKGROUND

[0002] An artificial fish reef is a structure set by humans in a water area, which aims to improve the ecological environment of the water area and provide a place for fish and other species to reproduce, grow, forage and seek refuge, so as to achieve the purpose of protection and increase of catch. Artificial fish reefs can be made of various materials, such as cement, steel bars, stones, tires, and waste ships and vehicles. Artificial fish reefs are divided into breeding type, attracting type, breeding type, fishing type, and protection type. Artificial fish reefs can improve the fishing yield and efficiency. According to statistics, the fishing yield in the area of artificial fish reefs is 3-10 times higher than that in the surrounding water area, and the quality is also improved. Artificial fish reefs can attract and gather various aquatic organisms in the surrounding water area, forming a relatively stable fishing ground. It can also change the direction and speed of water flow, forming an upwelling or vortex, bringing nutrients and organic matter to the upper water area, promoting the proliferation of plankton and benthic organisms, and providing abundant food for fish. Artificial fish reefs can provide breeding sites and incubators for some sessile or semi-sessile aquatic organisms. It can also provide shelter for some juvenile and small fish, reduce their risk of predation, and improve their survival rate and growth rate. Artificial fish reefs can provide attachment substrates for some seaweed, coral, and benthic organisms such as shellfish. These benthic organisms can consume organic matter and nutrients in the water through photosynthesis or filter-feeding, purify the water quality, and alleviate the occurrence of marine disasters such as red tide. At the same time, these benthic organisms can also provide food and habitat for other aquatic organisms, forming a complex and stable food web. Artificial fish reefs are an effective and economical method that can provide a safe and comfortable living environment for marine organisms and also bring multiple benefits to humans.

[0003] The existing artificial fish reefs generally only put a certain amount of bait at the beginning of construction to achieve the purpose of gathering fish, and then rely on natural proliferation, so they cannot achieve secondary bait feeding. Therefore, the effect of gathering fish is not good in terms of sustainability, and the proliferation effect is limited. SUMMARY

[0004] The present application aims to solve the problem that the existing artificial fish reefs cannot achieve secondary bait feeding, the effect of gathering fish is not good in terms of sustainability, and the proliferation effect is limited. The present application provides a fish gathering and breeding type artificial fish reef, which can feed bait again and even multiple times after a period of construction of the artificial fish reef, achieving the effect of gathering fish multiple times and for a long time, thereby improving the proliferation effect of the artificial fish reef and making it easier for a stable ecological community to form around the artificial fish reef.

The sealing plate discharge port of the bait barrel sealing plate is closed with water-soluble material, which can be dissolved and opened in a short time, and the bait is released and flows out, achieving the effect of initial baiting and realizing initial fish aggregation. After a period of time, especially when used in marine environment, the hanging rope for hanging the outward swinging arm is not enough to support the weight of the outward swinging arm after corrosion, and the outward swinging arm swings downward around the hinge point to the vertical position, and the bait in the bait bin flows out, achieving the effect of secondary baiting and realizing secondary fish aggregation. When multiple layers of outward swinging arms are provided, the thickness or number of strands of the hanging rope can be differentiated to control the outermost outward swinging arm to open first, and each layer of outward swinging arm opens from outside to inside in a certain period of time, realizing multiple baiting and multiple fish aggregation, and improving the proliferation effect of the artificial fish reef, so that a stable and stable ecological environment is formed around the artificial fish reef.

[0007] As a preferred embodiment, the upper surface of the bait bin is provided with a bait bin sealing plate, and the bait bin sealing plate is provided with a discharge port.

In the hanging state, the outer layer of the outward swinging arm is in the lower part, so the connecting leg is longer, so that the outward swinging arm is basically in a horizontal state in the hanging state, avoiding the leakage of bait.

[0010] As preferred, the outreach swing arm is arranged in multiple layers, the length of the outer layer outreach swing arm is greater than the length of the inner layer outreach swing arm, and the inner ends of the outreach swing arms of each layer are flush with each other at the lifting rope. The space is fully utilized, and different length of fish reef extension three-dimensional space is formed when the outreach swing arm swings open.

[0011] As preferred, the lifting rope is made of restraint wire, and when the outreach swing arm is arranged in multiple layers, the number of strands of the restraint wire for the inner layer outreach swing arm is greater than the number of strands of the restraint wire for the outer layer outreach swing arm. By arranging the number of strands of the restraint wire, the outer layer swing arm can be roughly controlled to swing open first, and the inner layer outreach swing arm can be controlled to swing open later, and the specific interval time of each layer of outreach swing arm to swing open does not need to be accurately controlled.

[0012] As preferred, the bait barrel is an annular barrel integrally extended around the outer wall of the fixed reef body.
