Problems solved by technology

In China, the history of seahorse breeding has been 50 years, but due to technical defects such as low reproduction rate, ineffective disease control, high mortality and backward bait cultivation technology, all the seahorse farms established earlier have all closed down

Embodiment 1

[0023] Embodiment 1 The establishment of artificial breeding ecosystem of the present invention

[0024] The artificial breeding ecosystem refers to the ecosystem formed by introducing producers, consumers and decomposers into the breeding ponds in a certain proportion, combined with the original functional organisms. By monitoring and controlling the output indicators, the balance of the artificial breeding ecosystem is controlled.

[0025] 1. Establishment of artificial breeding ecosystem

[0026] 1.1 Main technical indicators of artificial breeding ecosystem

[0027] 1) Total density of microalgae: 5×10 6 -8×10 6 / ml. Among them, the density of diatoms is 3-4×10 6 / ml.

[0028] 2) Total density of bacteria: 1×10 8 -1.5×10 8 / ml. Among them, the density of photosynthetic bacteria is 5×10 7 -9×10 7 / ml, bacillus density 1×10 7 -6×10 7 / ml.

[0029] 3) Total carbon content: 0.23-0.27mol / l.

[0030] 4) Total nitrogen content: 0.36-0.39mol / l.

[0031] 5) pH (pH):...

Embodiment 2

[0047] Method for cultivating bait in hippocampus culture of the present invention in embodiment 2

[0048] 1. Microalgae cultivation

[0049] 1.1 Preparation and disinfection of containers and tools

[0050] 1) Algae cultivation: commonly used utensils include triangular flasks, measuring cylinders, pipettes, beakers, platform scales or balances, electric stoves, aluminum pots, etc. The disinfection method is mainly heating method.

[0051] 2) Large-scale (productive) cultivation: In addition to the above-mentioned equipment, large-scale cultivation also requires inflatable equipment, cultivation tanks or cultivation buckets, etc. Disinfection methods are mainly chemical methods, and 1‰ formaldehyde solution disinfection is the most commonly used method.

[0052] 1.2 Culture medium preparation

[0053] 1) Seawater treatment: There are generally three methods for seawater treatment, including heating method, filtration method and chemical method. The algae culture generally...

Embodiment 3

[0105] Embodiment 3 Hippocampus ecological cultivation method and steps of the present invention

[0106] 1. Breeding procedures for primary seahorses

[0107] 1. Environmental parameters: temperature: 20-32°C, salinity: 16-34‰, pH: 7.8-8.4, light: 5000-10000lx, dissolved oxygen: 3-7mg / l.

[0108] 2. Cleaning and disinfection of the breeding pond: Scrub the whole pond, disinfect the whole pond with 1‰ formaldehyde solution, and rinse it three times with filtered seawater after about two hours.

[0109] 3. Water intake: The water for seahorse ecological breeding is natural seawater with secondary filtration. After entering the water, it starts to inflate.

[0110] 4. Establish a breeding ecosystem: establish a breeding ecosystem according to the method in Example 1.

[0111] 5. Seahorse stocking: newborn seahorses generally refer to seahorses from birth to four weeks, mainly for the breeding of seahorses. The stocking density of hippocampus within two weeks is 800-1000 tail...

Abstract

The invention provides a biological cultivation method of a sea horse, which comprises the following steps of: establishing a cultured biological system, cultivating a newborn sea horse, cultivating a young sea horse and cultivating an adult sea horse. In the sea horse cultivating technology provided by the invention, the supply of bait under an industrial condition is ensured by establishing thecultured biological system, accelerating maturity and cultivating the bait; diseases are effectively prevented and treated and the surviving rate is increased; the mature rate and the seedling yield can be greatly increased; the surviving rate of sea horse seedlings is 62.38%; the nurturance surviving rate is 89.52%; the seedling yield per fetus is 405.2; the unit yield is 0.613kg / stere; and the biological cultivation method is a new technology capable of realizing industrial cultivation.

Description

technical field [0001] The invention provides a seahorse ecological cultivation method. Background technique [0002] Hippocampus belongs to fish class, sea dragon family, hippocampus (Hippocampus). It mainly lives in shallow sea areas, and its distribution depth is generally within 10 meters. It is a precious medicinal fish. There are more than 50 species of hippocampus. There are 6 species found in China, among which the seahorse (H.kuda) and the three-spotted seahorse (H.trimaculayus) are the main breeding species. Big seahorses are suitable for farming along the coast of the South China Sea, while three-spotted seahorses are suitable for breeding along the coasts of the Yellow Sea, the Bohai Sea and the East China Sea. Others such as thorny seahorses and Japanese seahorses can also be cultured, but their survival rate is very low, so they are generally not considered as objects for industrialized breeding. Seahorses are dioecious. When male seahorses are sexually ma...
