Problems solved by technology

[0002] Loach likes yin and fears yang. It is a warm-water fish at the bottom. Its meat is light and tender. It is a low-fat and high-protein aquatic product. It is known as "water ginseng" and is deeply loved by consumers. However, in hot summer, when When the water temperature rises above 30°C, the appetite of the loach will decrease significantly, which will affect the normal growth of the loach and reduce the yield and quality of the loach

Abstract

The invention belongs to the technical field of loach breeding, especially to a method for ecological planting and breeding of loach and water chestnut. The method includes six steps as follows: pondselection, sludge fermentation, pond backfilling, cultivation of water chestnut, release of little loaches, and planting and breeding management. By the mixed planting and breeding mode of loach and water chestnut, the complementary effect is achieved: output and quality of loaches can be improved, and quality of water chestnut also can be enhanced. The method of the invention has significant economic benefits.

Description

technical field [0001] The invention relates to the technical field of loach breeding, in particular to an ecological breeding method for loach and water chestnut. Background technique [0002] Loach likes yin and fears yang. It is a warm-water fish at the bottom. Its meat is light and tender. It is a low-fat and high-protein aquatic product. It is known as "water ginseng" and is deeply loved by consumers. However, in hot summer, when When the water temperature rises above 30°C, the appetite of the loach will obviously decrease, which will affect the normal growth of the loach and reduce the yield and quality of the loach. [0003] Water chestnut, also known as waist water chestnut, water chestnut, water chestnut, and water chestnut, is the fruit of the annual herbaceous aquatic plant water chestnut. Water chestnut tastes sweet, flat, non-toxic, and the skin is crispy and fleshy. "Compendium of Materia Medica" records: "The water chestnut can nourish the spleen and stomach,...
