Embodiment 1

[0022] The shrimp paddy field covers an area of ​​20 mu. The middle part of the shrimp paddy field is set as shallow water beach 2. The shrimp paddy field is excavated along the surrounding area to form a deep water ditch 1. The width of the deep water ditch 1 is 2 meters. , Place bullfrog breeding cages in deep ditch 1, and place 400 square meters of bullfrog breeding cages per 10 acres of shrimp and rice fields. The cage specifications are 4.5m, 1.5m high and 1.5m wide. The bullfrog breeding cage is fixedly arranged in the middle and upper part of the deep ditch 1 through the bracket 3 . Since the bullfrog is an amphibious animal, and the floating board 5 can float on the water surface, it can provide the bullfrog with a land-based activity venue.

[0023] In March, the bullfrog seedlings were stocked in the bullfrog breeding cages in Shenshuigou 1. The size of the seedlings was 60 pieces / catties, the stocking density was 200 pieces / square meter, and the feeding rate of bull...

Embodiment 2

[0028] The shrimp paddy field covers an area of ​​20 mu. The middle of the shrimp paddy field is set as shallow water beach 2. The shrimp paddy field is excavated along the surrounding area to form a deep water ditch 1. The width of the deep water ditch 1 is 3 meters. , Place bullfrog breeding cages in deep water ditch 1, and place 500 square meters of bullfrog breeding cages for every 10 acres of shrimp and rice fields. The cage specifications are 4.5m, 1.5m high and 1.5m wide. The bullfrog breeding cage is fixedly arranged in the middle and upper part of the deep ditch 1 through the bracket 3 . Since the bullfrog is an amphibious animal, and the floating board 5 can float on the water surface, it can provide the bullfrog with a land-based activity venue.

[0029] In March, the bullfrog seedlings were stocked in the bullfrog breeding cage of Shenshuigou 1. The size of the seedlings was 70 / catties, the stocking density was 170 / square meter, and the feeding rate of bullfrog fee...

Embodiment 3

[0035] The shrimp paddy field covers an area of ​​30 mu. The middle of the shrimp paddy field is set as shallow water beach 2. The shrimp paddy field is excavated along the surrounding area to form a deep water ditch 1. The width of the deep water ditch 1 is 3 meters. The ditch surface of the deep water ditch 1 is 1 meter lower than the shallow water beach 2 , Place bullfrog breeding cages in deep water ditch 1, and place 500 square meters of bullfrog breeding cages for every 10 acres of shrimp and rice fields. The cage specifications are 4.5m, 1.5m high and 1.5m wide. The bullfrog breeding cage is fixedly arranged in the middle and upper part of the deep ditch 1 through the bracket 3 . Since the bullfrog is an amphibious animal, and the floating board 5 can float on the water surface, it can provide the bullfrog with a land-based activity venue.

Abstract

The invention discloses a mixed breeding mode of crayfish and bullfrog, which comprises the following steps: setting the middle part of a crayfish rice field as a shallow water beach, setting a deep ditch around the crayfish rice field, and enabling the ditch surface of the deep ditch to be 0.6-1m lower than the beach surface of the shallow water beach; net cages for bullfrog culture are arranged in the deep ditches; in March, bullfrog seedlings are bred in the bullfrog breeding net cage in the deep ditch, the specification of the bullfrog seedlings is 60-70 bullfrogs per jin, the stocking density is 120-200 bullfrogs per square meter, the bullfrogs are fished after being bred for 2-3 months, and the specification of adult bullfrogs is 150 g per bullfrog; 2-3 batches of young crayfishes are bred in the deep ditch from March to May, the specification of the young crayfishes is 100-120 crayfishes per jin, the stocking density is 6000-8000 crayfishes per mu, fishing is started after the young crayfishes are bred for 15-20 days, the fishing period is 15 days, and the specification of adult crayfishes is 25 g per crayfish; and rice is planted in the shallow water beach in June. According to the method, the crayfishes and the bullfrogs are subjected to polyculture, so that an existing shrimp rice field is dual-purpose, the bullfrogs are cultured while the crayfishes are cultured, and the culture benefits can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a mixed culture mode of crayfish and bullfrog. Background technique [0002] (Bullfrog (Rana catesbiana Shaw) belongs to Amphibia, Anura, Ranidae, and is a large edible frog with tender meat, delicious taste, rich nutrition and certain medicinal value. Bullfrog , commonly known as the American water frog, is large, grows fast, and has high yield. It is native to North America. In 1959, the bullfrog was introduced from Cuba to my country, and it has been widely promoted in my country since the 1990s. Chain restaurants and other forms have developed rapidly across the country, and are highly sought after by young consumers, and have become one of the important famous and special aquatic products in my country's aquaculture. [0003] However, with the expansion of the breeding scale, bullfrog breeding not only occupies a lot of tidal flats, ponds and farmland, but also the discha...
