Feed suitable for mixed culture of Basa fish and macrobrachium nipponensis and pollution-free mixed culture method of Basa fish and macrobrachium nipponensis

Abstract

The invention discloses feed suitable for mixed culture of Basa fish and macrobrachium nipponensis and a pollution-free mixed culture method of the Basa fish and the macrobrachium nipponensis. A feed formula comprises 24-42 parts of vegetable debris, 5-10 parts of hermetia illucens crushed powder, 5-10 parts of fly maggot powder, 15-20 parts of Chinese yam powder, 3-8 parts of immunopotentiator, 2-6 parts of multivitamins, 2-4 parts of radix angelicae, 5-15 parts of white radish, 2-4 parts of white poria, 25-40 parts of flour, 5-10 parts of lard oil, 1-2 parts of coconut oil and 15-20 parts of soybean oil. The feed is balanced in nutrition, meets the nutritional requirements of the Basa fish and the macrobrachium nipponensis, can induce the fish and the macrobrachium nipponensis to eat, and enables the fish and macrobrachium nipponensis growth speed to be high, enables the fish and macrobrachium nipponensis weight to be large, and enables the fish and macrobrachium nipponensis survival rate to be high. By adopting the feed, a large number of basa fishes and macrobrachium nipponensis can be harvested in a short time, and the economic benefit is improved. Meanwhile, according to the mixed culture method, a large net cage A is arranged in a shrimp culture pond, a net cage B is embedded in the large net cage, and the basa fish is cultured in the net cage B; and the macrobrachium nipponense is bred in a spaced feeding mode, and only the feed for mixed culture is fed. The method is low in shrimp pond transformation cost, easy to implement, simple to operate and suitable for popularization.

Description

technical field [0001] The invention belongs to the field of breeding technology, and in particular relates to a feed suitable for mixed culture of pangasius and giant macrobrachium japonicus and a pollution-free mixed culture method thereof. Background technique [0002] Pangasius, Latin scientific name: Pangasius bocourti, is an omnivorous animal. This fish is widely bred for its fast growth, large size, easy feeding, white and tender meat, delicious taste, rich nutrition, no small spines between muscles, and good processing. Households and consumers love. Pangasius is an important freshwater aquaculture species in Southeast Asian countries, and a small amount is distributed in Guangdong, Guangxi and Hainan in China. The domestic production is relatively low and cannot meet the demand of the market. Pangasius is suitable for growing in cages, cages and ponds, lakes and reservoirs with high dissolved oxygen. Pangasius is a tropical fish that has strict requirements on wa...
