Embodiment 1

[0025] A method for cultivating river snails with benthic bait biofilm mainly comprises the following steps:

[0026] (1) Planning of paddy field: delineate the rice planting area on the paddy field, and then delineate an area on both sides of the rice planting area as the cultivation area of ​​benthic bait biofilm. The rice planting area and the benthic bait biofilm The area ratio of the cultivation area is 9:1; a ditch with a depth of 25cm and a width of 2m is excavated between the rice planting area and the benthic bait biofilm cultivation area as the snail collecting ditch; the depth of the cultivation area of ​​the benthic bait biofilm 30cm; fertilize according to the standard of 500kg of basal fertilizer per mu in the rice planting area; set water inlet and water outlet on the field foundation of the cultivation area of ​​benthic bait biofilm, and the water outlet should be flush with the bottom of the field foundation or slightly lower, Install protective plates along t...

Abstract

The invention discloses a method for cultivating snails by using benthic bait biofilm, which mainly includes the planning of paddy fields, putting in fixation substrates, cultivating benthic bait biofilms, stocking snails and daily management steps. The invention uses rice straw or sugarcane Tip leaves are used as fixation substrates to introduce benthic algae and meiobenthos communities, and at the same time scientifically add bio-organic fertilizers to promote the growth and reproduction of benthic algae and meiofauna on the fixation materials, and finally cultivate the benthic bait biofilm suitable for escargot farming. Farming snails in paddy fields provides healthy and environmentally friendly feeding bait. The method has simple steps, is easy to operate, and is suitable for popularization and application in a large area.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates to a method for cultivating river snails with benthic bait biofilm. Background technique [0002] Escargot generally refers to molluscs of the family Snailidae, belonging to the phylum Gastropoda Probranchiae Snailidae, which is distributed in most parts of China. River snails like to live in waters where the winter is warm and the summer is cool, the bottom is soft, the bait is rich, and the water is fresh. They especially like to gather in places with micro-flowing water. Escargot has a variety of food habits, mainly eating tender stems and leaves of aquatic plants, organic debris, etc. Escargot likes to be active and feed at night, and the optimum temperature for growth is 20-27°C. The nutritional value of snails is very high. Every 100 grams of snail meat contains 18.2 grams of protein and 0.6 grams of fat. It also contains carbohydrates, calcium...
