Problems solved by technology

[0003] In addition, due to the rapid growth of mandarin fish seedlings, coupled with the continuous input of bait fish fry, the biomass in the unit water body is large, which has a great impact on water quality. It needs to be continuously divided into pools, which increases the difficulty of operation and also affects the normal cultivation of mandarin fish seedlings.

Embodiment 1

[0021] The mandarin fish seed rapid cultivation method of the present embodiment comprises the steps:

[0022] (1) Preparation of seedling breeding ponds: complete the site selection of seedling breeding ponds according to conventional methods, and construct protective measures for seedling breeding ponds according to conventional methods to prevent predators from entering and exiting; sprinkle lime one month before releasing mandarin fish fry Clear ponds, drying ponds, and fermented organic fertilizers are stacked at the four corners of the seed breeding ponds;

[0023] (2) Cultivate water: About one week before the seedlings, inject 40-50cm of water into the seedling breeding pond, then sprinkle tea dry into the seedling breeding pond, and then enter the water to a depth of about 1m, and the water quality will be light green when observed by naked eyes , There are rotifers in the water, and the water cultivation is completed;

[0024] (3) Preparation and stocking of bait fi...

Embodiment 2

[0029] The mandarin fish seed rapid cultivation method of the present embodiment comprises the steps:

[0030] (1) Preparation of seed breeding ponds: complete the site selection of seed breeding ponds according to conventional methods, and construct protective measures for seed breeding ponds according to conventional methods to prevent predators from entering and leaving; and build a ring around the seed breeding ponds In the canal, the bottom of the canal is covered with pebbles, and fishing nets are laid on the pebbles. The fishing nets are fixed by wooden stakes and ensure that the fishing nets are attached to the surface of the pebble layer at the bottom of the canal and both sides of the canal during the breeding period; the bottom of the canal is designed from Helical in height and low in height, a pipeline connected with the seed breeding pond is buried at the highest point of the bottom of the canal, and a large-hole filter screen is fixed on the nozzle of the pipelin...

Abstract

The invention discloses a method for quickly cultivating mandarin fish fries. The method comprises the steps of preparing a fry cultivation pond, cultivating water, preparing and stocking bait fishes,pretreating the mandarin fish fries, placing the mandarin fish fries, cultivating the mandarin fish fries and the like. According to the method provided by the invention, emergence can be realized within about 20 days, namely about 20 days are needed for cultivating the fries with the lengths about 1-2 cm to fries with the lengths about 10 cm, the fry cultivation period is shortened, and the economic benefit is increased.

Description

technical field [0001] The invention relates to a method for quickly cultivating mandarin fish seedlings, belonging to the technical field of aquatic seedling cultivation. Background technique [0002] Mandarin fish, also known as sweet-scented osmanthus fish, belongs to the family Sudidae. It has a tall body with flattened sides, a raised back, a large mouth, and the lower jaw is obviously longer than the upper jaw. Its meat is white, tender and delicious, and rich in protein. Eating it can nourish the five internal organs, benefit the spleen and stomach, inflate qi and blood, and treat deficiency. Mandarin fish is a typical ferocious carnivorous fish with a strong ability to distinguish bait. It mainly feeds on live fish and shrimp throughout its life. Even the fry that have just opened their mouths also eat the seedlings of other fish. Mandarin fish has the habit of eating the weak and the strong, and will eat each other when there is a lack of feed, which will affect th...
