Problems solved by technology

During this stage, the habitat and feeding habits of the fry of the peltago catfish have undergone drastic changes, resulting in extremely high mortality, and the biological source of bait at the bottom of the pond is unreliable and unstable, which intensifies the risk of disease in the sensitive period of the fry

Embodiment 2

[0032] On May 23, 2016, in Lingqiao Township, Huaiyin District, Huai'an, Jiangsu Province, a 5.2-acre pond of yellow catfish fry was selected, and the quicklime dry method was used to clear the pond; after 7 days of clearing the pond, fermented and sterilized manure was applied to the pond, and then injected into 80 mesh Sieve the water with silk to make the depth of the pool water reach 50cm; after one week, cut down the small grass on the edge of the pond, bundle it into 2.5kg / handle grass handles, and put the grass handles evenly on the surface of the pond, and the amount of planting is 13 handles / mu ; On June 9, 2016, 1 million fish fry were put into the pond; after the fish fry entered the pond, about 10 grass handles were added as needed; after the fish fry stabilized for 5 days, they gathered in the grass grass area of ​​Xiaopeng and began to tame the fish fry Special powder for yellow catfish, and then gradually transition to No. 0 extruded feed for domesticating yellow...

Embodiment 3

[0034] On May 18, 2017, in Lingqiao Township, Huaiyin District, Huai'an, Jiangsu Province, a pond of 4.5 mu of yellow catfish fry was selected, and the quicklime dry method was used to clear the pond; after 7 days of clearing the pond, the pond was made with a fertilizer and water product from a certain manufacturer, and then injected into an 80-mesh sieve Filter the water with silk to make the depth of the pool water reach 50cm; after a week, cut down the small grasses beside the pond, bundle them into 3kg / handle grass handles, and put the grass handles evenly on the surface of the pond at a rate of 10 handles / mu; 2017 On June 5, 2009, 1.2 million fish fry were put into the pond; after the fry entered the pond, about 8 grass handles were added as needed; after the fry stabilized for 3 days, they began to tame the special powder for fish fry and yellow catfish, and then gradually transitioned to domestication. No. 0 extruded feed is specially used for eating yellow catfish; aft...

Abstract

The invention discloses a method for helping Pelteobagrus fulvidraco fry quickly pass a sensitive period to effectively increase the survival rate, and belongs to the aquaculture field. The culture management method includes the steps: 1) making pond preparation and planting Conyza canadensis; 2) dropping the fry into the pond and taming; and 3) maintaining the ecological stability of the pond. The method for helping Pelteobagrus fulvidraco fry quickly pass the sensitive period to effectively increase the survival rate has the following advantages and positive effects: (1) attracting the fry to float on the surface of the water body for ingestion by means of the sufficient bait in the stem area of Conyza canadensis at the surface of the water body so as to help the fry pass the sensitive period quickly and effectively improve the survival rate of the fry; (2) effectively avoiding the disease risk caused by change of feeding habits of the fry to eat the bait at the bottom of the pond; (3) improving the immunity of the fry and enhancing the resistance of the fry to the disease; (4) being simple and clear in the operation method, being easy to obtain the materials, and having the prospect of demonstration and easy promotion; and (5) being an environment-friendly technology development, having a good safety record and having no potential environmental risks.

Description

technical field [0001] The invention relates to the aquaculture technology, in particular to a method for helping peltrigid fish fry to quickly pass through the sensitive period and effectively improving the survival rate. Background technique [0002] The yellow catfish belongs to the Silurformes (Silurformes), the family (Bagride), the yellow catfish ( Pelteobagrus ), endemic to East Asia, is a common carnivorous bottom-dwelling fish in rivers and lakes in my country. Its tender meat, delicious taste and no intermuscular thorns have won the favor of consumers. In recent years, it has been developed into a famous and high-quality freshwater aquaculture species with high economic value. However, in the current process of artificial breeding of yellow catfish, the fry mortality rate is extremely high. The fry breeding factories all overcome the problem of high mortality by increasing the number of parents and increasing the number of eggs laid, which not only increases the l...
