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.

2. Geese provide high-quality feed for the farmed fish. Geese are herbivorous poultry, and their droppings retain a high level of nutrients, making them feed for omnivorous fish and an excellent fertilizer for pond plankton. If goose droppings are scattered into the pond and decomposed by microorganisms for the fish to eat, this not only saves feed but also lowers farming costs. In a fish-goose combination, 1 goose produces 120-150 kg of droppings per year, which can be converted into 5 kg of fish, and 50-60 geese can be raised per mu of water surface.

3. The fish pond provides a clean environment for @#@232@#@. Geese are waterfowl, and the success rate of mating for adult breeding geese in water is noticeably higher than that of mating on the ground. Keeping geese on the water in summer can lower their body temperature and keep them in good spirits and appetite.

2. Forms of integrated fish-goose farming.

1. Raising geese outside the pond. Build a goose house near the fish pond, with an activity area for the geese and a wastewater pool outside. Every day, sweep the goose droppings and feed splashed by the geese into the activity pool, and then let them flow into the fish pond through the gate of the wastewater pool. Raising geese outside the pond is easy to manage, but it cannot fully exploit the mutually beneficial relationship between fish and geese.

2. Combined fish-goose farming. Build a goose house on the embankment of the fish pond, use part of the embankment surface and pond slope as the geese's activity area, and enclose a certain area of the fish pond with netting on one side as a swimming area for the geese. The underwater part of the arched net does not reach the bottom, so that fish can swim in through the bottom of the net to feed. This is better than letting the geese move around the entire pond, because it interferes less with the fish and is also easier to manage. Generally, the upper net is 40-50 cm above the water surface, and the lower net is 40 cm from the bottom. The stocking density for geese is an average of 3-5 birds per square meter for the goose house and activity area, and 2-3 birds per square meter for the swimming area. In combined fish-goose farming, the number of geese to raise alongside the fish is mainly determined by the amount of droppings the geese produce. Generally, 1 goose produces 120-150 kg of droppings per year, and 50-60 geese can be raised per mu.
