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 encountering inclement weather; the entanglements put in for entanglement habitat include thin bamboo filaments, polyethylene ropes, polyethylene inflatable tubes, etc. After soaking in water for a long time, dirt is easy to adhere to, causing Bacteria grows, which causes hippocampus disease

Embodiment 1

[0020] Example 1 Adopt the following steps to carry out artificial cultivation and cultivation of seahorse seedlings.

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

[0022] 2. Cultivation of juvenile seahorses and adjustment of breeding density and breeding density:

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

[0024] (2) As the body length of juvenile hippocampus grows to different stages, gradually reduce its breeding density and breeding density according to the following methods:

[0025] ①When it grows to a body length of 2.5-3cm, the breeding density is 650 fish / m 3 ;

[0026] ②When it grows to a body length of 4-5.5cm, the breeding density is 550 fi...

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...
