Problems solved by technology

However, the spawning capacity of broodstock is 10,000 to 30,000 per fish. When carrying out large-scale artificial breeding, in order to obtain fertilized eggs in batches, the demand for broodstock reaches thousands or even tens of thousands. The huge number of broodstock has increased. Cultivation difficulty
In addition, indoor cement ponds can only be used for small-scale broodstock cultivation, which cannot meet the large-scale broodstock cultivation required for large-scale artificial breeding, and water quality control and disease control are difficult.
So far, there have been no reports on the outdoor large-scale cultivation facilities and cultivation methods of the multi-scaled carp

Embodiment 1

[0020] 1. Selection of cultivation facilities: The outdoor strip-shaped track pool of the Donghai Island Marine Biological Research Base of Guangdong Ocean University is selected. The specification of the pool is 30.7m long and 1.5m deep. A 25m-long separation wall is built longitudinally on the centerline of the strip-shaped runway pool, and is equipped with a water purification system, an oxygenation system, and an egg collection system. The oxygenation system is a turbo aerator; the water purification system consists of a simple It is composed of water purifier and turbine aerator; the egg collection system is composed of fertilized egg collector and impeller aerator;

[0021] 2. Disinfect the pond, store water, and cultivate basic bait: After the water in the pond is drained, use 600kg of quicklime per hectare for disinfection; after the toxicity is over, extract filtered seawater to make the water level reach 1.5m; The calcium superphosphate of urea, 7.5kg carries out the...

Abstract

The invention discloses a method and a facility for large-scale cultivation of Sillago sihama parent fishes, and belongs to the technical field of artificial breeding of fishes. By adopting the cultivation method disclosed by the invention, appropriate conditions, reasonable nutrition arrangement and management and maintenance technologies can be provided for outdoor large-scale cultivation of the Sillago sihama parent fishes, batched fertilized eggs required by large-scale artificial breeding can be met, occurrence of diseases and control of water quality in the process of cultivating the parent fishes can be effectively reduced by being combined with outdoor ecological factors, and the survival rate of the parent fishes and the quality of the fertilized eggs are improved. The cultivation method is simple, the cultivation facility is easy to get, outdoor large-scale cultivation of the Sillago sihama parent fishes is easy to implement, and economic benefits are improved, thereby playing an extremely important role in industrialization development of Sillago sihama cultivation.

Description

technical field [0001] The invention relates to an outdoor large-scale cultivation method and facilities for multi-scaled carp broodstock, belonging to the technical field of fish artificial breeding. Background technique [0002] Sillago sihama Forskál belongs to the order Perciformes, the suborder Percoidei, the superfamily Percoidea, the family Sillaginidae, and the genus Sillago. It is distributed in Australia, India, Indonesia, the Philippines and Japan. It is also distributed in the Bohai Sea, Yellow Sea, East China Sea and South my country Sea in China, with a body length of up to 300mm. Commonly known as sand drill, boat smallfish, and wheat ears, the multi-scaled carp is an important economic fish in my country's coastal areas and occupies a very important position in my country's offshore fishing operations. However, due to overfishing in recent years, the individuals are getting younger, the population is getting smaller, and the output is decreasing year by year....
