Problems solved by technology

[0003] However, in the current breeding process, due to the lack of reasonable and effective breeding methods, the quality and quantity of fish cultivation have decreased significantly, and the existing breeding technology uses more chemical compounds and antibiotics in order to increase production. Drugs, etc. help fish grow too fast or solve the impact of various diseases and insect pests in the process of fish growth too quickly. The quality of the fish will change, and more importantly, after the use of chemical drugs or antibiotics, the drugs will remain in the fish and will be transferred to the human body during people's consumption, which will affect people's health. The use of antibiotics will pollute the environment, which is not conducive to ecological protection
At present, domestic fish farming mostly adopts pond culture, and the water in the pond is in a stagnant state, and the water quality is easy to deteriorate
Moreover, the taste of artificially fed fish is worse than that of naturally grown fish, the meat quality is loose, and the umami taste is reduced; while the naturally grown fish has a longer growth cycle and a smaller stock, which cannot meet the needs of the market

Embodiment 1

[0020] 1. Set up three fish ponds, each fish pond is interconnected, and the fish ponds are arranged horizontally, and the bottom of the ponds gradually lowers to form intercommunicating ponds of different depths. Blocking nets are set at the connecting ports of adjacent fish ponds, and water supply channels connecting the deepest and shallowest ponds are set outside the interconnecting ponds, and pumps are installed in the deepest ponds to pump water from deep ponds into shallow ponds to form an ecological living water aquaculture environment. The area of ​​each fish pond is 400m 2 , the height of the pond ridge is 3m, and each culture pond should be desilted first, and then disinfected with quicklime at a dosage of 1.5kg / m 2 , and finally exposed to the sun for 3 days and injected with water, the water injection depth is 1.5m for the shallow pool and 2m for the deep pool.

[0021] 2. When the water temperature is stable at about 10°C, the fry can be stocked, and the stockin...

Embodiment 2

[0026] 1. Set up five fish ponds, each of which is interconnected, and the fish ponds are arranged horizontally, and the bottom of the ponds gradually lowers to form interconnected breeding ponds of different depths. Blocking nets are set at the connecting ports of adjacent fish ponds, and water supply channels connecting the deepest and shallowest ponds are set outside the interconnecting ponds, and pumps are installed in the deepest ponds to pump water from deep ponds into shallow ponds to form an ecological living water aquaculture environment. The area of ​​each fish pond is 200m 2 , the height of the pond ridge is 3m, and each culture pond is desilted first, and then disinfected with quicklime, and the dosage is 2kg / m 2 , and finally exposed to the sun for 5 days before injecting water, the depth of water injection is 1.5m in the shallow pool and 2m in the deep pool.

[0027] 2. When the water temperature is stable at about 10°C, the fry can be stocked, and the stocking...

Abstract

The invention relates to an ecological cultivation method of domestic fish, which comprises the following steps of: 1) construction of a farm; 2) throwing fries; 3) running water management; 4) artificial feeding. According to the invention, a running water cultivation mode with a plurality of cultivation ponds with different depths which are communicated with each other is utilized, the method isof artificial natural ecological cultivation, promotes the growth of aquatic planktonic animals and plants, and maintains a good water cultivation environment. Meanwhile, scientific and nutritious artificial feed is prepared for feeding, and the cultivation yield of the fish is improved. By using scientific mixed cultivation ratio, the growth and living environments of the domestic fish are effective and stable and mutually promoted, and the cultivation quality is improved. The cultured domestic fish is delicious in flavor, good in taste, ecological, environment-friendly, low in cost and highin economic benefit, the method is suitable for large-scale production; meanwhile, chemical synthetic drugs and antibiotic drugs are not used, so that the produced fish has good quality and is safe to eat.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to an ecological breeding method for domestic fish. Background technique [0002] Herring, grass carp, silver carp, and bighead carp, as the four major family carp, are the main species of freshwater aquaculture. Due to the common characteristics of rapid growth and strong disease resistance of these four types of fish, they are suitable for consumption by the public, and the age of the growth inflection point of the four major fishes is 2-3 years older than their sexual maturity age, and they will continue to grow after sexual maturity. . With the rapid development of fish farming, the number of new breeds of fish has gradually increased, but the "four major fish" are still the main breeds. [0003] However, in the current breeding process, due to the lack of reasonable and effective breeding methods, the quality and quantity of fish cultivation have decreased significantly, and the e...
