Embodiment

[0025] This embodiment includes the following steps:

[0026] (1) Select species of frogs: at the end of September in the first year, select black-spotted frogs with strong vitality, high egg production and ovulation. The ratio of female frogs to male frogs is 1:1-1:1.2. The abdomen of the frog is swollen, the weight of the female frog is more than 50g, and the weight of the male frog is more than 40g. Both the female frog and the male frog are well-developed, have a strong body, no damage, no disease, are good at swimming and have a lively temperament;

[0027] The proportion of male frogs is slightly higher than that of female frogs, which can effectively prevent male frogs from competing for female frogs, causing casualties and affecting egg-laying.

[0028] (2) Cultivate kind of frog: the kind frog of selection is carried out feeding management before October, guarantees that kind of frog keeps good physique after surviving the winter, and kind of frog is put in a suitable...

Abstract

A method for cultivating black-spotted frogs, comprising the steps of: (1) selecting species of frogs; (2) cultivating species of frogs; (3) laying eggs and fertilization; (4) hatching of frog eggs; (5) feeding and management of tadpoles (6) the management of young frogs; (7) the management of becoming frogs; the present invention's egg laying capacity is big, and hatching rate is high, effectively avoids the ovum softening of frog ovum, and ovum collapses flatly, avoids the ovum rupture of frog ovum, hatches The hatching rate is above 90%, and the hatching quality is high; the survival rate of tadpoles is high, and the survival rate of tadpoles is above 95%; the black-spotted frog has strong vitality, large size, good quality, improved color and taste, and increased survival rate. The output is greatly improved, the growth cycle is shortened, the breeding cost is reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating black-spotted frogs. Background technique [0002] The black-spotted frog is a very common frog, belonging to the frog family, anura, and amphibians. The black-spotted frog has tender meat, less fat, low sugar, and high protein content. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. The artificial breeding of black-spotted frog is not only simple in technology, but also has fast economic benefits. Therefore, the breeding of black-spotted frog is an aquatic product. Breeding hotspots. [0003] The breeding of black-spotted frogs includes the selection of species of frogs, the cultivation of species of frogs, the fertilization of eggs, the hatching of frog eggs, the raising of tadpoles, the management of young frogs and the management of adult frogs, each of which is very important and will affect The survival...
