Embodiment 1

[0016] A method for ecological cultivation of perch in ponds, comprising pond construction, stocking, feed preparation, and cultivation, specifically:

[0017] Pond construction: choose a quiet and safe environment to build a pond with a water depth of 3.0m, install an aerator, and plant Elodea after filling the pond with 30cm of water. Every 4 stems are a bunch, and the plant spacing is 2m, and the row spacing is 2m. The pond is filled with water Afterwards, water peanuts were planted, with 6 stems in a bunch, planted around the pond, and then built a sunshade net. A large amount of oxygen, and the method of planting Elodea, water peanuts and sunshade nets can reduce the water temperature in summer, so that the water temperature can be controlled within 30 ° C, which is beneficial to the growth of perch;

[0018] Stocking: The stocking time is selected after the aquatic plants are planted, and the stocking density is 10,000 fish / mu. If the stocking density is too small, it wi...

Embodiment 2

[0024] A method for ecological cultivation of perch in ponds, comprising pond construction, stocking, feed preparation, and cultivation, specifically:

[0025] 1) Pond construction: choose a quiet and safe environment to build a pond with a water depth of 2.8m, install an aerator, and plant Elodea after filling the pond with 30cm of water. Each 4 stems are a bunch, and the plant spacing is 1.8m, and the row spacing is 2.5m. After the pond is filled with water, water peanuts are planted, and 7 stems are planted along the periphery of the pond, and then a sunshade net is built. The pond embankment is firm and the bottom of the pond is flat. The nano-oxygenation technology of the aerator is used to increase the dissolved oxygen in the water body. Provide enough oxygen for perch, and the method of planting Elodea, water peanuts and sunshade nets can reduce the water temperature in summer, so that the water temperature can be controlled within 30°C, which is conducive to the growth ...

Embodiment 3

[0032] A method for ecological breeding of perch in a pond. Choose a quiet and safe environment to build a pond with a water depth of 2.5m, install an aerator, plant Elodea and water peanuts, build a sunshade net, and then stock perch with a stocking density of 9,500 per mu According to the feeding rate of 9% of the body weight, the feeding frequency is 3 times a day, the feces and residual feed are siphoned 5 times, and the artificial light is used to prolong the photoperiod for 1 hour before sunrise and after sunset.

[0033] The ingredients and parts by weight of the above-mentioned feed are: 13 parts of fish meal, 15 parts of corn gluten meal, 18 parts of soybean meal, 25 parts of subflour, 6 parts of rice bran, 1.6 parts of soybean oil, 8 parts of Scutellaria baicalensis, 10 parts of Eucommia, 9 parts of honeysuckle, 0.16 part of bile acid, 0.5 part of food attractant, 0.15 part of silymarin, 1.2 part of antifungal agent. The ingredients and parts by weight of the antifun...

Abstract

The invention discloses a bass pond ecological culture method. The method comprises the steps of pond construction, stocking, feed preparation, and culturing, in particular, a quiet and safe environment is selected to construct a pond, aerators are installed, elodea nuttallii and alternanthera philoxeroides are planted, a sun-shading net is constructed, bass stocking is conducted by a stocking density of 9000-10000 stock per mu, culturing is conducted according to the method with the feeding rate of 7-11% of the feed body mass and the daily feeding frequency of 3-4 times. The bass pond ecological culture method has the advantages that the utilization rate of granulated feed by the bass is increased, the digestibility of feed protein and energy is increased, growth is promoted, productivity is increased, food waste and residual bait are reduced, summer water temperature is lowered by utilizing the combination of elodea nuttallii, alternanthera philoxeroides, and sun-shading net, energy consumption can be reduced, water eco-environment can be improved, and good ecological benefits can be achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for ecological cultivation of perch in ponds and an application thereof. Background technique [0002] Bass has the characteristics of fast growth, strong adaptability, few diseases, and good benefits. It is suitable for various forms of farming. Its meat is tender, delicious, nutritious, nourishing and strong, and is favored by consumers. The issue of quality and safety has drawn increasing attention from people. Producing healthy, high-quality, and pollution-free perch, and providing people with safe and secure aquatic products will become the development direction of perch farming. [0003] Songjiang perch belongs to the Sculptiformes, Sculptidae, Songjiang perch genus, is a carnivorous, ferocious fish. Songjiang perch is sexually mature at the first age, and the body length of sexually mature individuals is generally 12-17cm, and the weight is 40-100g. From April to June...
