Problems solved by technology

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 fresh water aquaculture system with controllable water temperature comprising a pond; the system is characterized in that a pond water heat exchange system is installed at the outer side of the pond; a water inlet pipe of the pond water exchange system is installed at one end of the pond; a water outlet pipe of the pond water exchange system is installed at the other side of the pond; a feeding device is installed inside the pond; the feeding device comprises a floating platform, a mounting platform is installed on the floating platform; a lifting mechanism which can life or lower the mounting platform is installed on the floating platform; an ejection device is installed on the mounting platform; a chemical adding barrel is connected to the storage barrel; the chemical adding barrel is connected with the storage barrel through a chemical adding pipe; a control valve is installed on the chemical adding pipe. The purpose of the invention is to overcome the deficiency of the prior art and to provide a fresh water aquaculture system with controllable water temperature with which the pond water temperature can be adjusted so that aquatic products can overwinter safely, the cultivation effect is good, the dispersibility of bait is good, and the feeding scope is wide.

Description

technical field [0001] The invention relates to a freshwater aquaculture system with controllable water temperature. Background technique [0002] Pond aquaculture is the main aquaculture production mode in my country. According to the "China Fishery Yearbook 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...
