Description

Hanging line type seeds catcher for shellfish culture}

The present invention relates to seed catchers for shellfish culture. More specifically, the present invention is fixed to a rope for aquaculture of adherent shellfish such as oysters or mussels, and then immersed in water and attached to a hanging line type seed catcher where the plaques are attached and grown. It is about.

In general, adherent shells such as oysters or mussels are passed through the process of "harvesting, chipping," and "harvesting." It is farmed.

The 'seeds' are the process of obtaining the seedlings, "natural seedlings" and "artificial seedlings". "Natural seedlings" are used to induce the attachment of mature larvae that have entered the attachment phase by immersing the cultivator, which is an attachment substrate, in the water at a certain time and place, and "artificial seedlings" in the water tank by means of temperature stimulation. After inducing spawning, the larvae are cultivated and attached to the extractor when they enter the attachment group.

"Further foster" is a process of growing the flocks attached to the harvester in water that can be artificially managed, and can be divided into a dropping, tree branching, and dialysis training method depending on the type of shellfish or the environment. For reference, a representative example of the droop type training method is a raft type, a rope type, a simple type, and the raft type hangs the hang yeon (垂下 延) to the raft mould and rafters to fix the chippers. However, the raft training method is rarely used at present because of high facility costs and inconvenient handling. On the other hand, the rope type floats a rich man on the sea surface, connects it with a rope, anchors both ends with an anchor, hangs a hanging rope on the rope, and fixes it with a picker. It is a relatively benign area and grows most rapidly. Are utilized. In the transplantation, two rows of horses are set up from the bottom of the low tide line to a depth of several meters, and suhayeon hangs on the crossroads interwoven vertically and horizontally, and the picker is fixed to cultivate the chip. In addition, the method of nurturing tree branches is commonly called Song Ji-sik, and it is established by cultivating branches, etc., between the basins of Sojo and control, and the dialysis type is attached to the exposed bottom surface between high and low tide. Put stones to cultivate.

"Harvesting" is the process of collecting and collecting the success of the adherent shellfish. The hook is rolled up, and the hand or machine is used to scrape off the successor attached to the harvester.

On the other hand, in conventional shellfish, adherent shellfish attach and grow in the harvester throughout the entire process from harvesting to harvesting.

As a result, the cultivator has a continuous and direct effect on the shellfish. In the past, mainly used natural materials such as oysters, scallops, and scallop shells, but in recent years, waste tire pieces have a certain size due to material cost reduction and the possibility of recycling after harvesting machines. It is universal to use it as a cut.

However, waste tires contain various organic chemicals such as rubber, tire cords, tire cores, etc., which contain a large amount of harmful components such as lead and bromine. It is highly likely that adverse effects of various harmful substances will have on the success or failure. Furthermore, due to the nature of the cultivator, which remains immersed in water until just before disposal, various harmful components have a high probability of adversely affecting the underwater ecosystem.

As a result, a drop harvester was introduced to replace scrap tires through Utility Model Registration No. 20-0335728 and Registration Utility Model No. 20-0244819, but most of them had low attachment rates and high desorption rates.
