Description

Temporary breeding pond for tubificidae

Technical Field

The invention provides a temporary breeding pond for tubificidae, and relates to the technical field of breeding equipment.

Background

The tubificidae has the advantages of fast reproduction and high nutritional value (the dry matter contains 62 percent of crude protein, the total amount of essential amino acid reaches 35 percent, and the nitrogen recovery rate reaches 98 percent), is a preferred initial feed for a plurality of aquatic animals in the fry stage, and is a main food for benthic fishes such as sturgeons, dangerous fishes, carps, crucian carps, loaches, giant salamanders, finless eels and the like.

If the tubificidae cannot be used up or sold out in the same day, temporary breeding should be carried out. 10-20 kg of tubificidae are temporarily cultured per square meter of the pool surface, and the tubificidae are regularly stirred and dispersed once every 3-4 hours to prevent the clustered earthworms from being dead due to oxygen deficiency. If the fish eats the dead tubificidae, various diseases and even death are easily induced, and if the young fish eats the dead tubificidae, the consequences are more serious. However, if the water earthworms are regularly stirred and dispersed once every 3 to 4 hours, a large amount of manpower and material resources are wasted, so that the development of a device suitable for temporarily breeding the water earthworms is urgently needed.
