Embodiment 1

[0017] An artificial pond culture method of flounder, comprising the following steps:

[0018] (1) Pond preparation: a rectangular pond with a depth of 90cm, a length of 50m and a width of 25m, remove part of the silt so that the thickness of the silt at the bottom of the pond does not exceed 25cm, and disinfect with quicklime before water injection. The amount of quicklime is 10g. Provide appropriate space for the growth of flounder. Before raising fish, use quicklime to thoroughly clean the pond to kill fish and pests, so as to ensure a good growth environment for fish; Brown flounder fry with a body length of 4 cm are placed in a fry box for temporary raising, and stocked in the morning or evening on a sunny day. When stocking, the fry are put into the pool together with a plastic bag. After three treatments of about 20 minutes, when the water temperature inside and outside the bag is the same, open the plastic bag, and the stocking density is 2.5 tails / m3 2 . If the stoc...

Embodiment 2

[0020] An artificial pond culture method of flounder, comprising the following steps:

[0021] 1) Pond preparation: area 1200m 2 , rectangular, the length-width ratio is 3 / 2, the depth of the pool is 110cm, the thickness of the silt at the bottom of the pool is not more than 25cm, and the dry method of quicklime is used for disinfection. Provide proper space for the growth of flounder, thoroughly clean the pond with quicklime before raising fish to kill fish and pests, so as to ensure a good growth environment for fish;

[0022] 2) Stocking of fingerlings: select fish with uniform specifications and a body length of 4.5cm for stocking, and the stocking density is 3 fish / m 2 . If the stocking density is too high, it is not conducive to the growth of fingerlings; if it is too low, the pond resources are wasted. This density ensures good growth of fingerlings and makes full use of pond resources;

[0023] 3) Feeding of bait: the feed to be fed is the commercial fish compound ...

Embodiment 3

[0027] An artificial pond culture method of flounder, comprising the following steps:

[0028] 1) Pond preparation: area 1500m 2 , rectangular, the length-width ratio is 2 / 1, the depth of the pool is 140cm, the thickness of the silt at the bottom of the pool is not more than 25cm, and the dry method of quicklime is used for disinfection. Provide proper space for the growth of flounder, thoroughly clean the pond with quicklime before raising fish to kill fish and pests, so as to ensure a good growth environment for fish;

[0029] 2) Stocking of fingerlings: select fish with uniform specifications and a body length of 4.5cm for stocking, and the stocking density is 2.5 fish / m 2 . If the stocking density is too high, it is not conducive to the growth of fingerlings; if it is too low, the pond resources are wasted. This density ensures good growth of fingerlings and makes full use of pond resources;

[0030] 3) Feeding of bait: the feed to be fed is commercial fish compound fe...

Abstract

The invention discloses a paralichthys olivaceus artificial pond breeding method. The method comprises the steps of pond preparation, fish fingerling stocking, fish bait feeding and water maintenance. The method has the advantages that the method is low in investment cost, high in breeding efficiency, little in environmental pollution and stable in paralichthys olivaceus production and has good ecological benefits and social benefits. Added mixed algae water purification agents are immobilized algae cells, the algae cells are high in synthesis metabolic activity and slow in aging and can effectively remove ammonia-nitrogen, nitrate and nitrite in water and improve water quality environment; the purification agents are easy in technology method, good in product quality stability, low in price and good in application effect and has good economic benefits.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial pond culture method of flounder.
