Description

Even heating device in holothurian culture pond

Technical Field

The utility model relates to a marine product field of breeding, concretely relates to even heating device in holothurian culture pond.

Background

The problem of low temperature in winter always exists in the culture of sea cucumbers in northern China, the optimum temperature for the growth of the sea cucumbers is 10-18 ℃, summer sleep starts when the temperature is higher than about 24 ℃, and winter sleep starts when the temperature is lower than 5 ℃. The lowest temperature in winter in the north is far lower than the temperature, so that the difficulty of artificial culture is increased, and a heating device is generally required to be provided for the sea cucumber culture pond, but the conventional heating device generally adopts single-point heating, so that the water temperature in the culture pond is not uniformly heated, and if multi-point heating is arranged, the culture cost can be greatly increased; and the water flow generated by the hot air can also cause the sea cucumber feces at the bottom of the culture pond to be raised in the water, so that the water area is turbid, and the growth of the sea cucumber is not facilitated.
