The integrated fish-goose farming model can increase economic returns by 30%.
Integrated fish-goose farming is a three-dimensional ecological farming model that combines poultry rearing with fisheries management. According to comparisons, under the same conditions, integrated fish-goose farming increases economic returns by about 30% compared with raising fish or geese separately. 1. Benefits of integrated fish-goose farming. 1. Geese are fully automatic, energy-saving and highly efficient aerators for fish ponds. In integrated fish-goose farming, farmers do not need to worry about oxygen depletion in the water caused by weather changes, because whenever the weather changes, the geese will scramble to jump into the water to bathe and chase each other, churning up splashes, which has a particularly good oxygenating effect on the fish pond.

Causes and Control Methods of Pear Black Heart Disease
In the early stage of the disease, brown patches appear on the outer skin of the fruit core. When the browning gradually expands to the entire core, the flesh shows browning with indistinct boundaries. Affected fruit deteriorates in flavor, seriously affecting the fresh-keeping storage life of Ya pears. Depending on the storage period and conditions, this disease can be divided into two types: early-stage black heart disease and late-stage black heart disease. The former occurs 30-50 d after being placed in cold storage and is considered to be caused by low-temperature injury during storage. The latter usually occurs under earthen cellar storage conditions, mostly around the Spring Festival of the following year, and is preliminarily considered possibly
