Problems solved by technology

However, most of the high-quality green finfish seedlings currently on the market are cultivated in the north. In the south, there are various technical bottlenecks and low economic benefits in cultivating the seedlings cultivated in the north according to the northern breeding method.
At present, there is no patent or literature report on the green-finned horse-faced fish raised in the north and raised in the south

Embodiment 1

[0029] Embodiment 1: The selection and transportation technology of green-finned horse-faced fish in the north and in the south

[0030] (1) Seed selection: choose healthy, disease-free, deformed, vigorous, well-fed, and 8-10 cm long green-finned fish seedlings bred in the north as the seedlings to be transported to the south for breeding.

[0031] (2) Preparation before transportation: fast for 12 hours to reduce the production of feces; increase the amount of water exchange in the nursery pond, so that the difference between the temperature and salinity and the sea temperature and salinity are not more than 3°C and 3°C respectively, and stabilize for 2 days before emergence.

[0032] (3) Transportation method: Carry green horse-faced fish seedlings on a running water boat and haul them along the coast, increase oxygen for 24 hours, and transport at a density of 500-600 fish / m³ to prevent damage and hypoxia during transportation; pay attention to speed during transportation, ...

Embodiment 2

[0033] Embodiment 2: The seedling selection and transportation technology of green-finned horse-faced fish raised in the north and raised in the south. During transportation, the transportation density is 500 to 800 / m³, and the others are the same as in Example 1;

Embodiment 3

[0034] Embodiment 3: The seedling selection and transportation technology of green-finned horse-faced fish raised in the north and raised in the south. During transportation, the transportation density is 600 to 800 / m³, and the others are the same as in Example 1;

Abstract

The invention discloses a thamnaconus septentrionalis northern breeding and southern feeding technology, and relates to the technical field of aquaculture. The thamnaconus septentrionalis northern breeding and southern feeding technology includes a seedling selection and transportation technology, an environmental adaptation technology and a daily management technology. By starting with three keytechnologies of thamnaconus septentrionalis northern breeding and southern feeding, the technical pioneer of thamnaconus septentrionalis northern breeding and southern feeding is created, the technical bottlenecks of southern feeding of excellent thamnaconus septentrionalis in northern breeding in different areas in terms of the transportation technology, the environmental adaptation technology and the daily management technology are solved, and technical breakthrough basis is creatively provided for thamnaconus septentrionalis northern breeding and southern feeding.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a technique for raising green-finned horse-faced fish from the north to the south. Background technique [0002] The green-finned horse-faced pufferfish belongs to the class of bony fishes and the family of single-horned pufferfishes. Its common names are rubber fish, skinned fish, pig fish and cobbler fish. It is one of the important marine economic fishes in my country, and its annual output is second only to hairtail. Greenfin horse-faced fish is a migratory fish near the bottom of the ocean, with a living temperature of 9-30°C, omnivorous, high feed utilization rate, fast growth, rich nutrition, and no hard spines in the edible part, which can be eaten fresh or processed Dried fish is an excellent economic fish. 150g of green-finned horse-faced fish can be sold. Since the 1990s, due to overfishing, environmental degradation and other reasons, the natural resources of t...
