Weight gaining rice field lobster culture method

Abstract

The invention discloses a weight gaining rice field lobster culture method which includes the steps: firstly, ditching a rice field, reinforcing ridges, cleaning the filed, disinfecting, planting submerged aquatic plants in rice ditches, planting floating plants at the edges of the rice ditches, and enabling the aquatic weed coverage rate of the rice field to reach 30%-40% or more; secondly, sequentially releasing dead branches and dead leaves to serve as food, natural organic fertilizers and young lobsters; releasing lobster feed once every 25-30 days after the young lobsters are released; adding and replacing water in all day, enabling water in the rice field to slightly flow, inspecting the field every day to observe whether head floating or death of the lobsters is present or not, examining reasons, and treating the conditions during growth of the lobsters; fishing up the lobsters to examine growth speed and breeding density every one-two weeks; fishing adult lobsters growing to reach 50-70 grams after the young lobsters are fed for 2-3 months. The method solves the problems of low lobster survival rate and small lobster size in existing rice field lobster culture.

Description

technical field [0001] The invention relates to a lobster culture technique, in particular to a method for fertilizing rice field shrimp culture. Background technique [0002] Crayfish are delicious and nutritious, and are deeply loved by people. They are the main species of shrimp farming at present. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. Therefore, to meet market demand through artificial scientific breeding, more and more people have begun to try ecological farming, such as raising crayfish in rice fields. The way of polyculture is to organically combine planting and breeding, make full use of the artificially created ecosystem, and make crayfish and rice mutually beneficial and symbiotic. Raising lobsters in rice fields has three advantages: one is to increase production and income; the other is that lobsters can eat wild weeds and aquatic organisms in ...
