How to raise Oncomelania angustifolia how to raise Oncomelania nipponensis

Site: choose the place with clear sea water, short water diversion distance, convenient drainage, high salinity, low water temperature in summer, less affected by typhoon and gentle ground. Water source: the salinity is between 25 ‰ and 35 ‰, the PH value is between 7.8 ℃ and 8.5, and the maximum temperature should not be more than 33 ‰. Feed: put more low-quality mixed fish, feed once every evening, the daily feeding amount is 3% of the snail body weight. Disinfection: the aquaculture pond should be washed every 10 days.

Oriental snail, also known as Oncomelania hupensis, is a snail with fast growth and high nutritional value. It is said that its meat is very delicious, tender and delicious, sweeping the coastal areas. So how to raise the square-spotted east snail covered with treasures? What good technologies can be recommended to you? Let's let the editor take you to understand it today.

How to raise Oncomelania nipponensis

1. Generally choose places with clear sea water, no pollution, short distance of water diversion, convenient drainage, no impact of fresh water, high salinity of sea water, lower water temperature in summer, less affected by typhoons, and relatively gentle ground. There are conditional requirements for water sources: generally, the annual salinity is between 25 ‰ and 35 ‰, while the PH value is between 7.8 ℃ and 8.5, and the maximum temperature is less than or equal to more than 33 ‰.

2. The snail mainly eats miscellaneous fish, shrimp, shellfish and crabs. Artificial feeding should put more low-quality mixed fish, which can be fed once a day in the evening, with a daily feeding amount of 3% of the snail's body weight. If the salinity is lower than 15 ‰ for a long time, the snail will die. In general, in heavy rainy weather, we should pay attention to the change of salinity of aquaculture pond. Also pay attention to the aquaculture pond flushed every 7 Mel 10 days, each kind of animal breeding should pay attention to the method, breeding square spot east wind snail is also the same.

Culture technique of Oncomelania nipponensis

1. Before breeding and stocking in the soil pond, the miscellaneous algae, silt and sundries in the pond should be removed in advance, and the pond should be exposed for about 10 days. Install 60 mesh sieve silk intake bags at the water intake, which can reduce the entry of harmful organisms such as fish, crabs and snails into the culture pond, and install a 20-mesh flat screen screen in the drainage.

2. After washing the caisson before stocking, surround the inner wall of the caisson with a 40-mesh screen, in order to prevent the snail seedlings from escaping, and then add a sand layer 5-6 meters thick. Bait can be given once every other day, and it is appropriate to leave a small amount of miscellaneous fish after 2 hours.

The above is all the detailed introduction about the square spot east wind snail, to sum up, in fact, the performance-to-price ratio of breeding east-spotted east wind snail is quite high, that is, we should pay more attention and be more careful when breeding, so that we can get twice the result with half the effort.
