Starvation feeding method at intervals of 7 days for pond culture of Pseudobagrus fulvidraco

Abstract

The invention discloses a starvation feeding method at intervals of 7 days for pond culture of Pseudobagrus fulvidraco. The feeding method for pond culture of the Pseudobagrus fulvidraco comprises thefollowing step: after continuous feeding for n days, feeding is stopped for 1 day, and starvation (feed deprivation) is performed circularly in accordance with the period, wherein n is equal to 7-10.According to the starvation feeding method at intervals of 7 days for pond culture of Pseudobagrus fulvidraco, traditional daily feeding is replaced with intermittent (starvation) feeding, and the input quantity of external fodder of aquaculture water, excretion of culture objects and the fodder cost are overall reduced while higher level compensation growth of the culture objects is achieved; besides, by (ingestion) utilization of plankton by the culture objects in the starvation period, the eutrophication degree of the water is reduced, and the self-cleaning level of the aquaculture water and the comprehensive culture benefit are increased. The method has positive significance in promoting healthy sustainable development of the aquaculture industry.

Description

technical field [0001] The invention relates to a method for feeding yellow catfish in ponds with starvation at intervals of 7 days. Background technique [0002] In the past 20 years, the systematic technology of yellow catfish farming in my country has developed from the initial reproductive biology research and small-scale domestication of "river fish" to large-scale artificial breeding, nursery and adult fish farming in recent years, as well as the development of special feed and hybrid yellow catfish Fish breeding and breeding, etc.; the breeding form has also developed from small water bodies such as cement ponds in the early stage to large-scale pond farming, pond cage culture, large water surface cage culture, and factory farming; the breeding area continues to increase, and the unit area Production continues to increase. However, large-scale, high-yield and high-feeding aquaculture have given rise to many problems. Among them, the lack of scientific and efficient fe...
