Embodiment 1

[0018] In this embodiment, the place of implementation is an intensive breeding base for knife fish. The implementation steps are as follows:

[0019]1. Plant submerged plants in the knife sturgeon breeding pond with a salinity of 0 ‰, and the area covered by submerged plants is 10%. In the breeding pond of knife fish four corners 50 m 2 Plant 2 grate eye vegetables per 100 cm in the area; Plant 2 shrimp algae, 2 goldfish algae and 2 foxtail algae every 60 cm on the surrounding four sides; In the central area of the pond, plant 4 vines of Sichuan vines every 80cm;

[0020] 2. Put an appropriate amount of small fish, rice shrimp and bran shrimp in the breeding pond of the knife fish: the density of 50kg / mu is 50kg / mu in the breeding pond, a total of 200kg. Every 10 days, it is necessary to make up the stock regularly, and the amount of stocking is 1 / 5 of the initial amount, a total of 40kg;

[0021] 3. Harvest the submerged plants in the ecosystem regularly: When the growth of grat...

Embodiment 2

[0023] In this embodiment, the place of implementation is an intensive breeding base for knife fish. The implementation steps are as follows:

[0024] 1. Plant submerged plants in the knife sturgeon culture pond with a salinity of 5‰, and the area covered by submerged plants is 8%. In the breeding pond of knife fish four corners 50 m 2 The area planted 2 grate eye vegetables every 90 cm; Plant 3 goldfish algae and 3 foxtail algae every 50 cm on the surrounding four sides; Plant 5 vines of Sichuan vines every 70 cm in the center of the pond;

[0025] 2. Stock an appropriate amount of small fish and bran shrimp in the breeding pond of the knife fish: the density of the stocking pond is 65kg / mu, a total of 260kg. Every 8 days, it is necessary to make up the stock regularly, and the amount of stocking is 1 / 5 of the initial amount, a total of 52kg;

[0026] 3. Regular harvesting of submerged plants in the ecosystem: When the area covered by plants exceeds 15% of the total water surface...

Embodiment 3

[0028] In this embodiment, the place of implementation is an intensive breeding base for knife fish. The implementation steps are as follows:

[0029] 1. Submerged plants are planted in breeding ponds with a salinity of 10 ‰, and the area covered by submerged plants is 5%. In the breeding pond of knife fish four corners 50 m 2The area planted 3 grate eye vegetables every 80 cm; Plant 5 foxtail algae every 50 cm on the surrounding four sides; Plant 5 vines of Sichuan vines every 60 cm in the center of the pond;

[0030] 2. Put an appropriate amount of small fish and bran shrimp in the breeding pond of the knife fish: the density of this stocking in the breeding pond is 70kg / mu, a total of 280kg. Every 7 days, it is necessary to make up the stock regularly, and the amount of stocking is 1 / 5 of the initial amount, a total of 56kg;

[0031] 3. Regular harvesting of submerged plants in the ecosystem: When the area covered by plants exceeds 22% of the total water surface, the young part...

Abstract

The invention discloses a configuration and management method for submerged plants in an anchovy ecological culture system. The method mainly includes providing shelter and breeding habitats for mysis by rationally arranging submerged plants in a culture pond for anchovy in the early stage. Solve the problem of insufficient bait for knifefish. In the later stage, the lush submerged plants planted in the early stage were pruned and transplanted to ensure the effective living space of the saury. The present invention provides a habitat and shelter for the reproduction of bait organisms such as fish and shrimp, provides a symbiotic environment for bait and swordfish, ensures a stable supply of fresh and live bait for swordfish, and shortens the existing artificial culture cycle of swordfish.

Description

Technical field [0001] The present invention relates to the field of aquaculture, specifically a knife fish ecological culture method. Background [0002] Knife fish, commonly known as knife fish, river knife, is a kind of river and sea migratory fish, usually living in the sea, from February to March every year from the sea into the river, and trace the river up for reproductive migration. Spawning groups follow the Yangtze River into lakes, tributaries or spawn on the main stream of the Yangtze River. However, in recent years, due to the intensification of pollution and the prohibition of fishing, the production of Yangtze River knife fish has declined year by year, and the wild Yangtze River knife fish is now on the verge of extinction. Therefore, artificial breeding and culture of knifefish for the purpose of developmental protection is imminent. [0003] The biggest difficulty faced by knifefish in captivity is the serious shortage of fresh food. Knife fish like live erbium,...
