Nutritional bait for growth and development stages of rana spinosa tadpoles

Abstract

The invention provides a nutritional bait for growth and development stages of rana spinosa tadpoles, which is prepared from the following raw materials in percent by weight: 22-25% of pumpkins, 22-25% of sweet potatoes, 20-24% of fish meal, 8-10% of silkworm chrysalis meal, 6-8% of wheat bran meal, 8-10% of kelp, 4-6% of saccharomycetes, 0.5-1% of calcium and zinc mixture, 1-2% of carrots and 1-2% of vitamin C. According to the principle of strong pertinence, convenience and feasibility, obvious effects and cost saving, animal and plant-derived matching feed is fed in fast growth and development stages of the rana spinosa tadpoles, so that local agricultural by-product resources and protein resources are fully utilized, the breeding cost is reduced, and reasonable allocation of the resources is realized; the mashed kelp which is added into the bait enhances the binding properties of a food pellet and causes no pollution to water quality; and the saccharomycetes can maintain the balance of the intestinal flora of the tadpoles, promote the health growth of the tadpoles, shorten the metamorphosis stage of the tadpoles, improve the survival rate of the tadpoles to the metamorphosis stage as well as increase the economic benefits.

Description

Technical field [0001] The invention relates to a spiny-breasted frog breeding technology, in particular to a nutrient bait for the growth and development of spiny-breasted frog tadpoles. Background technique [0002] Spiny-breasted frog, also known as stone frog, stone chicken, pit frog, stone frozen, stone scale, etc., is a large wild frog unique to my country, belonging to the amphibian Anuraidae, mainly distributed in the mountainous areas of southern my country. Spiny-breasted frogs have delicious meat, high nutritional value and medicinal value. The market potential is huge, and prices continue to rise. Therefore, the artificial breeding of spiny-breasted frogs has significant social and economic benefits. [0003] The spiny-breasted frog tadpoles live in water and breathe with their gills. The tadpoles rely on the yolk sac to maintain their nutrition for 4 to 5 days after they emerge from the membrane. After the yolk is digested, they begin to feed. Its survival rate is dir...

AI Technical Summary

Problems solved by technology

However, during artificial breeding, there are common problems as follows: unbalanced nutritional mix, single types of plant-based bait and animal protein, excessive consumption leads to waste, and increases the economic cost of breeding; food clumps are easy to disperse and pollute water quality, and water quality deterioration causes tadpole disease , seriously affected the survival rate and growth and development level of Rana spinosa tadpoles
