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 an anti-freezing cultivation system, comprising a pond. The outer side of the pond is provided with a pond water heat exchanging system. The middle part of the pond is provided with a feeding salvage ship. The feeding salvage ship comprises a ship body. The rear end of the ship body is provided with a feeding device. The feeding device comprises a mounting plate. The mounting plate is provided with an ejection device. A storage vat is internally provided with a material pushing plate mechanism which makes materials smoothly enter a discharging port. The front end of the ship body is provided with a salvage mechanism which salvages suspended objects of the pond. The ship body is provided with a driving mechanism which can drive the ship body to travel. An objective of the system is to overcome defects in the prior art, and the anti-freezing cultivation system which is simple in structure, adjusts water temperature of pond water, makes aquatic products safely overwinter, and is good in cultivation effect, good in bait dispersibility in feeding, wide in feeding range, and can salvage the suspended objects in the pond.
Description
technical field [0001] The invention relates to a freezing-proof breeding system. 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 have an ecological environment for...
