Description

Technical Field

[0001] The utility model belongs to the technical field of sea cucumber seedling cultivation, in particular to an egg washing and water changing device for sea cucumber seedling cultivation. Background Art

[0002] Sea cucumbers are dioecious, but their sexes are difficult to distinguish visually. Therefore, it's difficult to accurately monitor the male-to-female ratio during spawning and ejaculation. Sex can only be determined by observing the characteristics of these events, and males must be removed from the pool promptly to prevent excess semen from affecting fertilization. However, even with prompt removal, excess semen in the pool water is inevitable.

[0003] To address this situation, "egg washing" is necessary to remove and dilute excess semen from the spawning pool. Traditional egg washing typically involves siphoning water from the spawning pool and then adding seawater to filter and dilute the excess semen. This involves siphoning the water through an egg washing cage and a siphon tube. Excess semen is filtered through the cage and then removed, and fresh water is added to complete the egg washing. Alternatively, siphoning and diluting the eggs can be performed while adding fresh seawater.

[0004] Because nets typically use 300-mesh silk screens, while semen can be filtered through the nets, the fertilized eggs can adhere to the nets due to the suction force of the siphon effect, causing them to be exposed and damaged. Traditionally, the only way to wash away the eggs is to use a long scoop to continuously splash pool water around the edges of the nets. This traditional egg-washing device and manual operation is time-consuming, labor-intensive, and extremely damaging to the eggs. Utility Model Content
