Embodiment Construction

[0020] The steps of the cultivation method of the golden-haired barb seed in Dianchi Lake of the present invention are as follows:

[0021] 1. Design of holding pool

[0022] The golden-thread barb fry in Dianchi Lake that have just emerged from the film can be endogenously nourished, and they need to be temporarily raised in the holding pond until they swim horizontally, and then they can be transferred to the outdoor cultivation pond for artificial cultivation. The holding pond designed in this design is built in a greenhouse. It is a concrete structure with a length, width, and height of 6m, 1.4m, and 0.6m, respectively. The fry are bruised and cleaned immediately. Each holding pool is an independent water inlet and drainage system. The water inlet is a long strip pipe located above the holding pool. The spray water enters the pool. There is an anti-escape fence made of 60-mesh stainless steel mesh in front of the water outlet. Inlet and outlet water volume and water leve...

Abstract

The invention relates to a cultivating method of a sinocyclocheilus grahami seedling, belonging to the technical field of fish culture. The cultivating method comprises the steps of the cultivation of fish fries growing mouths in rich water, artificial cultivation of fish fries, the rearing of fish fries at middle and rear stages and pest control. In the cultivation of fish fries growing mouths in rich water, a temporarily-cultivating pond is arranged in a tunnel, bait for fish fries growing mouths is chlamydomonas and rotatoria cultivated in rich water and the fish fries are cultivated at water temperature of 15 DEG C for 10-12 days. In the artificial cultivation of fish fries, the fish fries are cultivated by eel powder feed with the protein content of 40 percent for 40 days. The feed in the fish fries at middle and rear stages is carp crushed feed with the protein content of 39 percent. In the pest control, the water quality and the conditions of fish bodies are detected every three days, 50-80ml / mu of povidone iodine for controlling bacterial infection and 50-50ml / mu of rotatoria one-time removal (ammonium ethylene-bis-dithiocarbamate) for controlling balantidiasis are splashed every 15 days. The invention can effectively improve the survival rate and the growth speed of inocyclocheilus grahami seedlings, is simple and convenient, and is beneficial to being popularized and generalized. Bacterial.

Description

Technical field: [0001] The invention relates to a method for cultivating golden-threaded barb fry in Dianchi Lake, belonging to the technical field of fish farming. Background technique: [0002] Dianchi golden threadfish (Sinocyclocheilus grahami Regan), also known as Dianchi golden threadfish, pineapple fish, and small cave fish, is distributed in rivers, caves, and underground rivers in Dianchi Lake and its watershed. The golden-threaded barb in Dianchi Lake has delicious meat and is the first of the "Four Famous Fishes" in Yunnan. It has extremely high development value and market prospects. However, the golden-threaded barb in Dianchi Lake is a small cold-water fish, and its individual growth and development are relatively slow. After artificially induced spawning and reproduction, it will take a long time for the fry to swim, feed, and grow naturally. The death caused is serious, and the fry survival rate is not high. How to solve the above problems has attracted th...
