Beijiang special cranoglanis bouderius fry special bait and preparation method and device thereof

Abstract

The present invention discloses a Beijiang special cranoglanis bouderius fry special bait. The Beijiang special cranoglanis bouderius fry special bait is prepared from the following components in parts by weight: 19 parts of fish meal, 17 parts of nitrofurazone, 18 parts of raw bran, 1.6 parts of phospholipid oil, 1.4 parts of bacillus, 9 parts of chicken meal, 7 parts of soybean protein concentrate, 20 parts of alpha starch, 2 parts of monocalcium phosphate, 3 parts of phospholipid oil and 4 parts of a functional additive; and the functional additive is prepared from the following componentsin parts by weight: 5 parts of carnivorous multivitamins, 5 parts of rare earth, 5 parts of betaine, 2 parts of magnesium acetate, 2.5 parts of anti-microorganism peptide, 1.5 parts of bacillus, 15 parts of herba dendrobii and 16 parts of melilotus officinalis. The present invention also discloses a preparation method and preparation device of the Beijiang special cranoglanis bouderius fry specialbait. When the provided special bait for the cranoglanis bouderius is used, growth speed of the cranoglanis bouderius fry is increased, disease resistance is enhanced, the betaine is added as luringjuice for use to lure eating by the cranoglanis bouderius, the bait is avoided from sinking to a bottom of a pond to be wasted, utilization rate of the bait is greatly improved, and adverse effects ofthe residual bait on water quality are reduced.

Description

technical field [0001] The invention relates to the technical field of special aquaculture, in particular to a special bait, a preparation method and equipment for fry of the Beijiang special fish, the long-breasted catfish. Background technique [0002] In recent years, with the improvement of people's living standards, traditional freshwater fish, such as carp, silver carp, and bighead carp, can no longer meet people's needs. Ze crucian carp and loach, carnivorous eel, Northeast six-bearded catfish, black snakehead, yellow catfish, mandarin fish, long-ripped catfish. According to the conditions of the aquaculture water body, the species and specifications of fish culture, the type of water area and the culture measures, freshwater fish culture is divided into the following methods: a. Still water fish culture and running water fish culture b. Monoculture, polyculture and nest culture c. Pond culture Fish, rice field fish farming, river fish farming, lake fish farming, res...

AI Technical Summary

Problems solved by technology

The long-breasted catfish is listed as a vulnerable object in my country. It is a special fish in the Pearl River system. It likes a clear and flowing water environment. Its survival temperature is 0°C-38°C. Normal growth requires dissolved oxygen above 3 mg/L and adapts to a pH value of 6. -8.5. However, over the past decades, due to overfishing, deepening industrial pollution, and loss of suitable living temperature and pH, the number of snails has decreased significantly, and artificial breeding of scorpions has to be carried out to maintain fishery production.

[0004] However, with the rapid expansion of the aquaculture area, many problems have arisen in the culture of artificially bred catfish fry.

At present, the breeding of freshwater carnivorous fish in my country mainly relies on natural fresh bait, which not only consumes a lot of manpower and material resources, but also easily carries pathogenic bacteria, which brings disease trouble
