I. Environmental conditions
1. The site selection environment requires seclusion, cool in winter and cool in summer, convenient in traffic and convenient in management. Mountain streams, cold springs, or groundwater require adequate water sources and stable water temperatures. The maximum summer water temperature in summer should be less than 30°C. Drainage and irrigation are convenient, and there is no pollution source that poses a threat to water quality. The water quality of the water source should meet the requirements of GB 11607.
2. Breeding facilities for breeding facilities are required to be ventilated and cool. All kinds of frog ponds are suitable for brickwork and cement plastering. They are square, and the bottom of the pool is slightly inclined. The upper part of the tank is installed with water inlet pipe and the lowest part is provided with drainage holes. The pool is equipped with water surface, land, stone caves, food table, etc. cover. Aquaculture sheds should be set up in the aquaculture ponds that are built outdoors, and should conform to the living habits of the spiny-breasted frogs.
Second, into a frog breeding technology
1. Disinfect the frog pool 10 days before the stocking of the frog pond, and disinfect the frog pool in accordance with the provisions of SC/T 1008-1994 "Technical Specifications for Conventional Fry Breeding in Ponds".
2. Choose the frog species When stocking, remove the disabled and deformed frogs and select the young ones with neat specifications, robust physique and bright color.
3, stocking density: stocking density with reference to the following table (slightly)
4, frog species disinfection frog species with 3-4 salt solution before soaking or with 10mg/L ~ 15mg/L potassium permanganate solution soak 10-15 minutes.
5. Water quality management requires constant flow for a long time to keep fresh water, sufficient dissolved oxygen, and stable water temperature.
6, feeding and management
(1) The fed feed is mainly live bait such as Tenebrio molitor, and the live bait requires puffiness. In the appropriate temperature range, the daily feeding amount is 5-10 of body weight. When the temperature is higher than 30 °C, you can not feed. Normally, it should be increased or decreased according to the weather, water quality, and frog's ingestion, and it should be appropriate and uniform.
(2) Grading rearing: With the increase of individual frogs and the occurrence of different sizes, they should be sorted and sorted according to the size of the sheds, so as to avoid young rush to eat, affect the growth and survival rate.
(3) Overwintering management: When the water temperature is lower than 8°C, the spiny-breasted frog enters hibernation. When the water temperature drops to 10°C, the outdoor spines and frogs must be moved indoors or covered in winter. There is no need to feed during the winter. After the spring outdoor water temperature has steadily risen above 10°C, the spine-breasted frogs are overwintering.
7, disease prevention
(1) The common diseases of spiny-breasted frogs are hydromycosis, red-leg disease, rotten skin disease, and gastroenteritis. Should be prevention-based, active treatment, careful medication. Strictly carry out disinfection of frog ponds and frogs, and routinely disinfect the drugs every 10-15 days; the individual who died will be removed at any time, and the sick individual will be treated in isolation.
(2) Use of fishery drugs: The types, usages, dosages, and precautions of drugs needed for prevention and treatment of frog disease should be governed by NY 5071-2002 "Guidelines for the Use of Non-Hazardous Food and Fishery Drugs." The use of banned drugs prescribed by the state is strictly prohibited.
(3) Predator control: The protective net should be stamped at the upper mouth of the frog pool to prevent creatures such as rats, birds, and snakes from harming creatures. Filters should be installed at the inlet and outlet to prevent aquatic insects and grasshoppers from entering.
The spine-breasted frog, commonly known as the stone frog and chukar, is a unique large-scale wild frog in China. The spiny-breasted frog is delicate and white in flesh, sweet in taste and nutritious. It is listed as a famous dish of the hotel and restaurant, and it is also a rare and precious dish. And it has nourishing and strengthening body, pure heart and lungs, healthy liver and stomach, nourishing damage, as well as antipyretic toxin and diarrhea. According to the biological learning of spiny-breasted frogs, in recent years, due to excessive capture and environmental deterioration, the resources of spiny-breasted frogs have become increasingly scarce. In order to develop this traditional and unique treasure on the basis of the conservation of the wild resources of the spiny-breasted frog, this year, with the support of the Hangzhou Agricultural Development Fund Office and related departments at a higher level, the Hangzhou Aquatic Technology Promotion Station cooperates with the Jiande Aquatic Industry Association. The ecological breeding experiment of spiny-breasted frogs was conducted and good ecological and economic benefits were achieved. The commodity frog raised using the imitation eco-breeding model has good quality, is similar to the wild, has the advantages of investment, high efficiency, and a pretty market. It is particularly suitable for qualified mountain farmers to use the natural flow water resources such as streams, springs, and groundwater for development and breeding, and has a low risk of breeding and a broad market prospect. The technical points for the ecological development of pollution-free frogs are summarized below for reference by farmers.
