Description

Technical Field

[0001] The invention relates to the technical field of pearl oyster seedling cultivation, and in particular to a vertical seedling cultivation system for pearl oysters. Background Art

[0002] The shell length of the conventional clam seedlings (juvenile clams) just detached from the fish body is about 0.3mm. After about a month of cultivation, it can grow to 1.0-2.0cm. Juvenile clams have strict requirements on the cultivation environment, requiring sufficient dissolved oxygen and rich bait organisms. Generally, more than 40,000 seedlings are produced per square meter. In such a high-density environment, it is necessary to keep the water fresh and prevent the tiny individual clam seedlings from being washed away by the water flow, so the water flow cannot be too fast and can only flow in the upper layer. The clam seedlings live in the bottom mud and sand. As the juvenile clams develop and the individuals grow larger, the water quality needs to be gradually improved from clear to rich, the bait supply needs to be gradually increased, and the bottom mud and sand should be increased accordingly. At present, the cultivation of common juvenile clams, such as the juvenile clams of the triangular fan clams, basically adopts the cultivation method of small pools and micro-flow water in greenhouses. Generally, ponds are used to cultivate bait algae, and the water flows through the water storage tank to the greenhouse. The cultivation pool in the greenhouse is generally 1-1.5m 2 It is square, 15cm deep, made of stacked bricks or cement, with plastic film laid inside to prevent leakage, and a small amount of fine mud and sand laid on the bottom. Each culture pool has an inlet and an outlet. In order to make full use of water sources and save energy, the pond and the water storage tank are higher than the greenhouse culture pool, so that the water flowing out of the culture pool can be pumped back to the pond by a water pump for recycling. In the existing shellfish seedling breeding process, due to the movement of water flow and mussel seedlings, as well as the deposition of suspended matter in the water body, the shellfish seedlings are often unevenly distributed, piled up, or covered by excessive mud and sand, thereby affecting the survival and final emergence rate of the shellfish seedlings. In order to ensure that each mussel seedling obtains sufficient dissolved oxygen and rich bait, it is necessary to strictly prevent the uneven distribution and even accumulation of shellfish seedlings. In production, the bottom of the pool can only be stirred by hand every day to wash the floating mud. It requires a lot of time and labor costs for the breeders; and even so, due to labor limitations, if the pool water is not stirred in time or the stirring is not perfect, some shellfish seedlings will accumulate and die of lack of oxygen, which seriously affects the survival rate and emergence rate of the shellfish seedlings.
