Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the examples. However, the following examples should not be considered as limiting the scope of the present invention.

[0030] In the present embodiment, the method for cultivating juvenile fish in indoor cement pond of money fish comprises the following steps:

[0031] (1) Seedling cloth: newly hatched larvae are clothed in indoor cement ponds with an area of ​​16-20m 2 , the seedling water level is 1 / 4 of the full pool, and the seedling density is 7500-10000 tails / m 3 , scattered gas stone 1.2-1.4 pieces / m 2 , Dissolved oxygen is kept above 6mg / L.

[0032] (2) Water temperature control: when the fry are 1-20 days old, the water temperature is controlled at 29±1°C; after 21-30 days of age, the water temperature is maintained at 26±1°C.

[0033] (3) Salinity control: The water used for seed cultivation is prepared from concentrated seawater (baume degree 11-12), local natural seawater (sali...

Abstract

The invention relates to the technical field of scatophagus argus culture, and provides a indoor larva and juvenile fish cultivation method for scatophagus argus in a cement pond. The method comprisesthe eight steps of fry distribution, water temperature control, salinity regulation and control, illumination, dirt absorption, water change, tank turning culture and bait feeding. A bait sequence and a feeding method for the young scatophagus argus are established, and the technical problem of first feed of scatophagus argus fries is solved; and the technical parameters of the cultivation waterenvironment of the young scatophagus argus are determined, a temperature control and salt regulation technology is adopted, the growth efficiency and the cultivation survival rate of the young scatophagus argus are improved, and the blank in the field of artificial cultivation of young scatophagus argus is filled.

Description

technical field [0001] The invention belongs to the technical field of money fish culture, and in particular relates to a method for raising young fish in an indoor cement pond of money fish. Background technique [0002] Money fish (Scatophagus argus), also known as golden drum fish, belongs to the order Perciformes, family Scatophagidae, and the genus Scatophagus. The money fish lives in the confluence of brackish and fresh water at river estuaries. It belongs to estuarine fish. It is native to Indonesia, Thailand, the Philippines and other places. The body of the money fish is flat and disc-shaped, the body color is colorful, the meat is delicious, and it has the dual value of viewing and eating. It has become a new species of artificial breeding in the coastal areas of southern my country in recent years. [0003] At present, the seedlings of goldfish mainly come from wild fish caught in the sea. With the deterioration of the sea area environment and overfishing, the na...
