Temperature-controlled circulating water system for jellyfish breeding

Abstract

The invention provides a temperature control circulating water system for jellyfish seedling growing, and belongs to the technical field of aquaculture equipment. The system comprises a temperature control device, a blocking device, a drainage system and a water inlet system. Temperature control circulating water for jellyfish seedling growing is achieved by the system, water temperature of the seedling growing water is ensured to be stable, the damage rate of the jellyfish seedlings can be effectively reduced, technical support is provided for jellyfish breeding in the summer high temperatureseason, and the jellyfish breeding time can be prolonged, thereby increasing the seedling yield. The system can also be applied to water change applications in acetabulum and young jellyfish periods.

Description

technical field [0001] The invention belongs to the field of seawater aquaculture facilities, and in particular relates to a temperature-controlled circulating water system for raising jellyfish seedlings. Background technique [0002] Jellyfish (Rhopilema esculentum) is a kind of large edible jellyfish. It is rich in protein, vitamins, inorganic salts and other nutrients. It has high economic value and has always been one of the important fishing targets in my country. Since the 1980s, the natural resources of jellyfish have declined significantly, and more jellyfish proliferation and release activities have been carried out in my country's coastal areas. After entering the 21st century, jellyfish pond culture has developed rapidly, and the research work on industrialized jellyfish breeding has also been carried out rapidly. In particular, the jellyfish breeding industry in Liaoning and Shandong provinces has developed relatively rapidly, with considerable benefits, and the...

Problems solved by technology

[0004] In the existing jellyfish artificial breeding technology, the pro-stings are generally caught in summer, and they are temporarily raised in the pond until the water temperature drops to about 24°C, and then used for seed breeding. Due to the long holding time, there are adult stings Due to problems such as high mortality rate and gonadal degeneration, the production unit needs to reserve a large amount of adult stingers, which greatly increases the breeding cost of the enterprise. Using artificial temperature control to complete the breeding in the high temperature season in advance is a practical way to solve this problem. However, jellyfish The swimming ability is weak, especially the fertilized eggs and floating larvae are weaker, and the swimming ability cannot compensate for the displacement caused by slight water flow, that is, the individual moves with the water flow

Therefore, when using circulating water for temperature control, individuals tend to gather with the water flow and block the screen, causing individual damage, resulting in inefficient operation of circulating water, unstable water temperature, and affected fertilization and hatching processes
