Problems solved by technology

[0003] At present, no breeding method for silver white fish seed has been found, and even the existing breeding methods for other white fish genera under Cyprinidae of Cyprinidae are rarely recorded. Artificial breeding is urgently needed to promote the recovery and expansion of silver white fish in Dianchi Lake

Embodiment 1

[0016] Embodiment 1: Method for industrialized fry seed cultivation of silver white fish. Well water is used in the cultivation tank, and shade nets are arranged on the top of the tank; fertilized eggs are placed in the cultivation tank for hatching, and the density is 12,000 grains / m 3 Water, the water temperature is kept at 13-17°C, after the yolk sac of the fry emerges from the film and absorbs energy to swim horizontally, the shrimp fry microemulsion compound feed No. 1 produced by Shandong Yinuo Haimu Biological Co., Ltd. and water are used in a weight ratio of 1:200. After dilution, feed with a straw, feed 6 times a day, and feed bait weight 1g per square meter each time; the main measures for water quality control are air pump aeration and oxygenation, and regular renewal of tank water 1 / 3-1 every 5-7 days / 2, the sewage at the bottom of the tank is discharged by siphon method; when the fish fry grow to a total length of 12mm-15mm, the water temperature is kept at 14-18°...

Abstract

The invention belongs to the technical field of fish fry breeding, and specifically relates to a method for industrialized fry seed cultivation of silvery white fish. The method adopts shrimp fry microemulsion compound feed, shrimp fry microsphere bait compound feed and carp fry compound feed to replace natural bait. Net shade treatment, in the middle and later stages, use ultraviolet disinfection and photosynthetic bacteria to adjust the water quality, and properly control the oxygenation time of the air pump and the amount of water exchange. This method has the advantages of land use, less water, high survival rate of seedling cultivation, high degree of intensive production, and easy industrialization development. It is also in line with the policy orientation of national ecological environment protection and is worthy of promotion.

Description

technical field [0001] The invention belongs to the technical field of fish fry breeding, in particular to a method for industrialized fry breeding of silver white fish. Background technique [0002] Silver white fish (Anabarilius alburnops) is a unique indigenous species in Dianchi Lake. Due to the introduction of alien species, overfishing and other factors, as well as the rapid development of urbanization and industrialization in Kunming after the late 1980s, industrial, agricultural and domestic pollution has increased, the ecological environment of Dianchi Lake has undergone great changes, and the water quality has deteriorated. , the population of almond fish in Dianchi Lake has decreased sharply and almost disappeared. It has been listed as endangered by the "China Red Book of Endangered Animals-Fish", "China Species Red List Volume 1", "IUCN Red List", and also by Yunnan Province. Listed as endemic rare protected animals. Silver white fish used to be the main econo...
