Abstract

The invention discloses a method for breeding river snails by feeding the river snails with passionfruits. The method includes the following steps of 1, breeding pool management, wherein a layer of modified attapulgite clay wrapped in a filtering bag is put at the bottom of a pool, the thickness of the layer of modified attapulgite clay is 3-6 cm, the modified attapulgite clay is soaked in water with the pH value of 7.5-8.5 for 14-20 days, the water in the pool is drained, and the filter bag is taken out, 2, stocking management, and 3, feeding management, wherein the river snails are fed for 180-200 days, 0.3-0.6 kg of passionfruit pulp is poured at night every day, 0.5-1 kgof feed is poured every 2-3 days, and when round sclerites of the river snails are sucken into river snail shells, 0.05-0.1 kg of nutrition powder is mixed with the feed to feed the river snails together. The bred river snails are high in yield, low in heavy metal content and good in taste, and the method has broad popularization value.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of escargot cultivation, in particular to a method for cultivating snails with passion fruit. [0003] 【Background technique】 [0004] Field snails generally refer to molluscs of the family Snailidae, belonging to the phylum Gastropoda Probranchia Snailidae. Escargot is distributed in most parts of China. Escargot has higher requirements on water quality and less yield. Available in summer and autumn. Escargot is an ovoviviparous animal with a unique reproductive mode. The embryonic development and snail development of the snail are all completed in the mother's body. From fertilized eggs to the generation of young snails, it takes about one year to conceive in the mother's body. Field snails lay eggs in batches, and start breeding from March to April every year. While producing young snails, the female and male parent snails mate and fertilize, and at the same time conceive the young snails to be produced...
