But the effect is not ideal enough, the survival rate is not high
[0004] In addition, in order to improve the efficiency of breeding work, feeding devices are generally used when feeding feed to the farming area. Due to design defects, the current feeding devices on the market have poor dispersion of bait when feeding, and fish and shrimp need to be concentrated. eat in a small area
it's bad for feeding

Abstract
The invention discloses a cultivation system with a controllable water temperature. The cultivation system with the controllable water temperature comprises a pond, and is characterized in that a pond water heat exchange system is arranged on the outer side of the pond; a water inlet pipe of the pond water heat exchange system is arranged in one end of the pond; a water outlet pipe of the pond water heat exchange system is arranged in the other end of the pond; a material throwing device is arranged in the pond; the material throwing device comprises a floating platform; a launching device which can launch a material in a material throwing disc out of a material outlet seat is arranged on the floating platform; a material storagebarrel is connected with a medicine adding barrel; the medicine adding barrel is connected with the material storage barrel through a medicine adding pipe; a control valve is arranged on the medicine adding pipe. The cultivation system with the controllable water temperature is simple in structure, good in cultivation effect, wide in material throwing range and controllable in water temperature; the water temperature of the pond water can be adjusted, so that aquatic products can winter safely; bait dispersity is high when the aquatic products are fed.
Description
technical field [0001] The invention relates to a culture system with controllable water temperature. Background technique [0002] Pond aquaculture is the main aquaculture production mode in my country. According to the "China FisheryYearbook 2010", as of 2009, my country had 4.164 million hectares of aquaculture ponds, with a production of 18.5291 million tons of pond aquaculture, including 2.332 million hectares of freshwater aquaculture ponds, with an output of 15.489 million tons. Pond aquaculture accounted for 51.2% of the total aquaculture production , has become the main source of aquatic product supply in my country. [0003] Safe wintering is a difficult problem in aquaculture at present, especially for finished fish or shrimps and crabs under severe winter conditions, such as tilapia, dace, catfish and other fish, the survival rate of overwintering is as low as about 30%, and the survival rate of fry is as low as 30%. It's even lower. In order to have an ecolog...
