Problems solved by technology

[0005] In traditional artificial cultivation, the newly hatched seedlings of hippocampus mainly feed on rotifers, copepod nauplii, etc., and then feed adult copepods, small crustaceans, amphipods, etc. Most of these baits are fished from sea areas , cannot be supplied normally when enco

Example Embodiment

[0020] Example 1 The following steps are used for artificial cultivation and breeding of sea horse seedlings.

[0021] 1. In an area of ​​12m 2 6 air stones are placed at the bottom of the breeding pond. After thorough disinfection, sand filtered seawater is added to the breeding pond, and the seawater depth is 1.0m.

[0022] 2. Cultivation of young sea horses and adjustment of breeding density and breeding density:

[0023] (1) Move the newly hatched young sea horses with a body length of 0.8~1.0cm into the breeding pond. At the beginning, the breeding density of young sea horses is 1300 / m 3 ;

[0024] (2) As young sea horses grow to different stages of body length changes, gradually reduce their breeding density and breeding density according to the following methods:

[0025] ① When the body length is 2.5~3cm, the breeding density is 650 / m 3 ;

[0026] ②When the body length is 4~5.5cm, the breeding density is 550 / m 3 ;

[0027] ③When the body length is 6~7cm, the breeding density is ...

[0042] Example 2 The following steps are adopted for artificial cultivation and breeding of sea horse seedlings.

[0043] 1. In an area of ​​13m 2 7 air stones are placed at the bottom of the breeding pond. After thorough disinfection, the aquaculture pond is filled with sand-filtered seawater, and the seawater depth is 1.1m.

[0044] 2. Cultivation of young sea horses and adjustment of breeding density and breeding density:

[0045] (1) Move the newly hatched young sea horses with a body length of 0.8~0.9cm into the breeding pond. At the beginning, the breeding density of young sea horses is 1400 / m 3 ;

[0046] (2) As young sea horses grow to different stages of body length changes, gradually reduce their breeding density and breeding density according to the following methods:

[0047] ① When it grows to a body length of 2.5~3cm, the breeding density is 700 / m 3 ;

[0048] ②When the body length is 4~5.0cm, the breeding density is 500 fish / m 3 ;

[0049] ③When it grows to a body length...

[0064] Example 3 The following steps are adopted for artificial cultivation and breeding of sea horse seedlings.

[0065] 1. In an area of ​​15m 2 8 air stones are placed at the bottom of the aquaculture pond. After thorough disinfection, sand-filtered seawater is added to the aquaculture pond to a depth of 1.2m.

[0066] 2. Cultivation of young sea horses and adjustment of breeding density and breeding density:

[0067] (1) Move the newly hatched young sea horses with a body length of 0.9~1.0cm into the breeding pond. At the beginning, the breeding density of young sea horses is 1500 / m 3 ;

[0068] (2) As young sea horses grow to different stages of body length changes, gradually reduce their breeding density and breeding density according to the following methods:

[0069] ① When it grows to a body length of 2.5~3cm, the breeding density is 680 fish / m 3 ;

[0070] ②When the body length is 4.5~5.5cm, the breeding density is 530 fish / m 3 ;

[0071] ③When it grows to 7~8cm in length, th...

Abstract

The invention discloses a yellow seahorse seedling artificial cultivating and farming method, belonging to the technical field of aquaculture. The method comprises the following concrete steps of: feeding yellow seahorses with proper larvae or adults of moina mongolica and mysis or post larvae of litopenaeus vannamei according to the body length of newly-hatched young yellow seahorses and yellow seahorses in a farming process; and when the young yellow seahorses grow to 2.5-3.0cm, simulating an ecological environment condition of the yellow seahorses in a natural sea area, and supplying sargassum or eucheuma for the yellow seahorses to twine and perch. According to the method disclosed by the invention, fed baits are artificially cultivated, have rich nutrition and can be obtained stably, and can not be influenced by weather and seasonal effects; fed twining objects can promote the self growth by use of harmful substances in the farming environment, sufficiently reduces the content of the harmful substances in water, realizes an effect of purifying the water quality, reduces diseases of the yellow seahorses, and improves the survival rate and the released density. The method disclosed by the invention is easy and convenient to operate and has an obvious effect.

Description

technical field [0001] The invention relates to a technique for artificially cultivating and cultivating seawater economic fish seedlings, in particular to a method for artificially cultivating and cultivating seahorse seedlings, and belongs to the field of aquaculture. Background technique [0002] Seahorses belong to the genus Hippocampus of the family Hydrasauridae, and are widely distributed in tropical, subtropical and temperate near inland seas where seaweed and seagrass grow luxuriantly. When it is still, it wraps its tail around objects that can be attached to seaweed and the like, and sometimes drifts with the floating objects. There are more than 30 species of seahorses in the world, and there are 5 species of seahorses common in the coast of my country, namely the big seahorse, the lined seahorse, the three-spotted seahorse, the small seahorse and the spiny seahorse. The hippocampus is flat and tall, with a protruding abdomen, and the trunk is composed of 10-12 b...
