Method for breeding monopterus albus and pelteobagrus fulvidraco in same pond

Abstract

The present invention belongs to the technical field of aquaculture, and particularly relates to a method for breeding monopterus albus and pelteobagrus fulvidraco in the same pond. The method comprises the steps of: (1) arranging a net cage on the upper part of water in the pond, and breeding monopterus albus in the net cage; breeding pelteobagrus fulvidraco in the lower part of water; (2) setting the net cage to be 3 m long, 2 m wide and 1 m high, and enabling the upper end of the net cage to be above the water surface by 40 cm, and enabling the lower end of the net cage to be below the water surface by 60 cm; (3) putting 1.5 kg of monopterus albusper fries per square meter of the net cage, wherein the weight of each fry is 35 g; and putting 5000 pelteobagrus fulvidraco fries per mu, wherein the weight of each fry is 35 g; (4) respectively feeding monopterus albus expanded pellet diet with protein content of 40% and pelteobagrus fulvidraco expanded pellet diet with protein content of 35%, wherein a feeding ratio per day is 3-5% of the weight of each fry; and (5) during the rearing period, spraying lime water monthly to improve the water quality of aquaculture. According to the method, space and time of the water in the pond are fully utilized, thereby effectively improving the comprehensive benefits of the water in the pond.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, relates to the cultivation of commercial fish in the aquaculture, and in particular relates to a method for cultivating ricefield eels and yellow catfish in the same pond. Background technique [0002] Both rice field eel and yellow catfish are the main targets of farming in our country, and the market is in short supply. In the ponds where rice field eels are raised in cages, the water outside the cages is usually only stocked with a small amount of other fish, the space and time of the pond water are not fully utilized, and the comprehensive production potential of the pond water is not fully tapped, thus the potential of the pond water is not brought into play. Comprehensive economic benefits. Contents of the invention [0003] The invention aims to provide a method for cultivating ricefield eels and yellow catfish in the same pond, so as to achieve three-dimensional development and com...
