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...
