Description

Technical Field

[0001] This invention relates to the field of injection killing devices, and in particular to an underwater device and system for injecting and killing Spiny Sea Spinosaurus. Background Technology

[0002] Sea prawns are species belonging to the genus *Symplocos* in the family Symplocidae, order Echinodermata, class Asteridae, phylum Echinodermata. They are carnivorous and can feed on shellfish, crustaceans, polychaetes, and even small fish, with a particular fondness for bivalve mollusks such as mussels, oysters, and clams. Some species have a single diet, feeding only on bivalve mollusks, but most are polyphagous or omnivorous.

[0003] *Symplocos buergerianus*, a species of the genus *Symplocos*, is commonly found in the Yellow and Bohai Seas of my country, and is widely distributed along the North Pacific coast, in the waters of Korea, Russia, Japan, and northern Canada. *Symplocos buergerianus* exhibits periodic outbreaks; for example, in the waters off Akira and Kyushu, Japan, periodic outbreaks occur every 10 years. In the 1980s, due to shipping and the movement of larvae with ocean currents, *Symplocos buergerianus* was introduced to Australia, becoming an invasive species along the coast of Tasmania, and causing large-scale outbreaks that severely damaged local fisheries and benthic ecosystems. Molecular geography studies indicate that the genetic structure of *Symplocos buergerianus* populations in Tasmania is similar to that in Japan.

[0004] *Hemiberleinii* is pentagonal in shape, flattened, slightly convex dorsally, and with a very flat mouth. It has five arms, each approximately 14 cm in diameter at the radial end and 3.7 cm in diameter at the interradial end. The arms are wide at the base, slightly compressed, and taper towards the tip, with very thin edges. The dorsal plates form a dense network. The dorsal spines are short and not very densely distributed; each spine has a slightly widened and flattened tip with fine serrations. The superior margin forms the edge of the arm, with 4-5 (-6) spines, sometimes up to 7. The spines are mostly short and columnar, slightly enlarged at the tip, and have longitudinal grooves. The inferior margin is on the mouth, generally with 3 spines, sometimes 2 or 4, slightly longer and thicker than the superior margin spines, with blunt tips. The lateral ambulatory spines are very irregular, each bearing several straight forked spines.

[0005] The spiny sea snail, nicknamed the "beautiful killer" and "sea locust," preys on clams cultured in nearshore waters, severely damaging the profits of clam farmers. It grows and reproduces rapidly, with each individual laying up to 15.5 million eggs. To prevent outbreaks of this sea snail and the resulting damage to shellfish aquaculture, we should strengthen the monitoring and early warning of the nearshore environment and ecosystem, and promptly carry out injection-based culling.

[0006] Currently, existing injection-based methods for killing sea spurges have the drawback of low efficiency.

[0007] Therefore, those skilled in the art are dedicated to developing an underwater device and system for injecting and killing *Hemiberlesia lataniae* to overcome the shortcomings of the prior art. Summary of the Invention

[0059] Example 1

[0060] The steps for using the device and system for diving and harvesting sea bass in this invention are as follows:

[0061] Step 1: Pre-fill the syringe with injection solution, place medium-sized mussels in the trap net, and turn the first reel device to make the fishing net and trap net sink to the seabed.

[0062] Step 2: Connect the power supply to make the motor rotate, which will drive the first rotating gear and the second rotating gear to rotate, thereby driving the underwater camera installed on the vertical pole to rotate towards the fishing net. The operator can observe the captured images to monitor the entry of the sea bass into the net in real time and carry out the net retrieval operation in a timely manner.

[0063] Step 3: During the net closing, for any escaped sea snails, an injection-based capture operation is performed. The motor drives the meshing first and second rotating gears to rotate, monitored in real-time by captured images. Once the target direction is reached, rotation stops, and the second reeling device is rotated. Initially, the second reeling device tightens the mechanical claws. After releasing the line, the claws extend and retract due to the elasticity of internal springs, capturing the sea snail. After covering the sea snail, the third reeling device is rotated, tightening the lines at the top of each claw hook, converging at a point, and combining with the cloth on the sides of each claw hook to form a sealed space, covering the sea snail. Simultaneously, the third and second reeling devices are used to reel in the line, bringing the captured sea snail back to its original state.

[0064] Step 4: After the third and second reeling devices have completed their reeling operations, the crossbar returns to the compressed state. At this time, the spiny sea snail is captured in the claw and the injection head is inserted into the spiny sea snail. Manually push the injection head push rod to perform the injection operation. After the injection is completed, release the third reeling device to proceed with the next injection and capture operation.

[0065] This invention discloses a device and system for diving and harvesting sea snails, which can kill a large number of sea snails with high efficiency, no need for manual diving, good safety, and simple and easy operation. Different harvesting methods can be used simultaneously or separately, saving time.

[0066] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
