Embodiment 1

[0012] A culture method for grass carp, comprising the following steps:

[0013] (1) Pond construction: build a rectangular breeding pond with an area of ​​5 mu, a water depth of 1.5 meters, and a silt thickness of 0.2 meters. A large number of aquatic plants will be planted in the breeding pond, and an aerator with a power of 2 kilowatts per mu will be equipped. and one automatic bait feeding machine;

[0014] (2) Equipment before stocking: Drain the pond water in winter, freeze and dry for more than 20 days, sprinkle 150g quicklime per mu to disinfect the pond, inject sterilized lake water or river water 2 days after disinfection, and put the stocking fry into salt water for soaking Put it into the pond after 10 minutes;

[0015] (3) Stocking: put grass carp in the culture pond first, divide the ponds after 450 days, and then put the mature fry into the culture ponds from April to early July, stock 400 grass carp, 100 silver carp, 50 The tail is yellow catfish, 100 silver ...

Embodiment 2

[0019] A culture method for grass carp, comprising the following steps:

[0020] (1) Pond construction: build a rectangular breeding pond with an area of ​​7 acres, a water depth of 2 meters, and a silt thickness of 0.3 meters. A large number of aquatic plants will be planted in the breeding pond, and an aerator with a power of 2 kilowatts per acre will be built. and one automatic bait feeding machine;

[0021] (2) Equipment before stocking: Drain the pond water in winter, freeze and dry for more than 20 days, sprinkle 150g quicklime per mu to disinfect the pond, inject sterilized lake water or river water 2 days after disinfection, and put the stocking fry into salt water for soaking Put it into the pond after 10 minutes;

[0022] (3) Stocking: Put grass carp in the culture pond first, divide the ponds after 480 days, and then put the mature fry into the culture ponds from April to early July, and stock 400 grass carp, 100 silver carp, and 100 fish per mu in the culture pond...

Abstract

The invention relates to the field of aquaculture, and specifically relates to a grass carp culturing technology. According to the invention, water temperature and stocking time are controlled, such that fish fry survival rate can be improved. Different fishes are stocked at a same time, such that the pond and the water surface can be kept clean. Spotted silver carp helps in removing suspended matters, yellow-head catfish helps in reducing parasitic disease occurrence, and crucian helps in cleaning the river bottom. Therefore, grass carp quality safety is high, and farmer economic benefit is ensured.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating grass carp. technical background [0002] Grass carp generally likes to inhabit the middle and lower layers of rivers, lakes and other waters and areas with many aquatic plants near the shore. It has the habit of migrating in rivers and lakes. Sexually mature individuals spawn in rivers and rivers. After spawning, broodstock and juveniles enter tributaries and lakes through rivers, usually in submerged shoal grasslands and flooding areas and subsidiary water bodies of main and tributary streams ( Lakes, creeks, harbors and other aquatic and grassy areas) feeding and fattening. In winter, it overwinters in the deep water of main streams or lakes. Grass carp is a typical herbivorous fish with a lively temperament and fast swimming. It often forages in groups and is gluttonous. It feeds on zooplankton in the fry stage, and insects, earthworms, algae and duckwee...
