Description
Technical Field
The invention belongs to the field of sea horse cultivation, and particularly relates to a large-scale grey sea horse cultivation method based on a biological floc principle.
Background
The hippocampus is a traditional rare Chinese medicine. According to statistics, the amount of dry medicine used in China is more than 300 tons every year. Because natural resources in China are exhausted recently, most of the sea horses required by the market at present are imported, the price is increased year by year, the average price exceeds 7000 yuan per kilogram, and the value exceeds 21 billion yuan according to 300 tons imported per year. Because natural resources of the sea horses are seriously damaged, artificial breeding research is carried out in many countries in the world for recovering the resources. In recent five years, the Hippocampus culture technology taking Hippocampus erectus as a leading variety in China is developed rapidly, but the large-scale production technology still has many problems, and low quality seedlings and low culture survival rate in summer are one of the main problems to be solved urgently at present.
The sea horse can be bred for many times in one year, and in nature, the breeding season is generally spring and autumn, mainly spring. Under artificial conditions, the seedlings can be bred in four seasons, but the quality of the seedlings is reduced in summer or after continuous breeding for multiple times. The immunity of the low-quality seedlings is reduced, and the bacteria are quickly propagated due to high temperature in summer, so that enteritis and other bacterial diseases are easy to outbreak during the culture period in summer, and the full army of hippocampus can be induced to submerge. Although temperature reduction is a technical option in summer, the effect is not ideal, and the large-scale culture cost is high, so that how to improve the survival rate of the young Hippocampus japonicus in summer is one of the important problems to be solved in the current Hippocampus japonicus culture.
The biological flocculation technology is a technology which is characterized in that organic carbon substances are added into a water body by controlling a water body nutrition structure, the C/N ratio in the water body is adjusted, the propagation of heterotrophic bacteria in the water body is promoted, the inorganic nitrogen is assimilated by microorganisms, culture metabolites such as ammonia nitrogen and the like in the water body are converted into bacteria self-components, and the bacteria are flocculated into granular substances to be ingested by cultured animals, so that the effects of maintaining the water environment stable, reducing water change amount, improving the immunity of the animals, improving the culture survival rate, increasing the yield, reducing the feed coefficient and the like are achieved. However, biological flocks are not suitable for all the objects to be cultivated and have high technical requirements, in particular, the requirement of large air inflation amount and no dead angle. The sea horse is small in size and weak in swimming ability, and the inflation is not suitable for sea horse cultivation. In addition, the biological floc water for large-scale animal culture is required to form a real floc which can be ingested by a culture object, the sea horse is different from common fishes, and the excessive floc in the floc water is possibly not suitable for the survival of the sea horse. Therefore, the standard biological floc technology is not suitable for the sea horse, but the principle can be used for culturing sea horse culture water so as to achieve the purposes of improving the immunity of the sea horse, reducing the disease incidence and improving the culture survival rate.
