Mixed culture of fish and geese can increase economic benefit by 30%.

Three-dimensional breeding of fish and geese is a three-dimensional ecological breeding model of poultry breeding and fishery comprehensive management. According to comparison, under the same conditions, the economic income of comprehensive culture of fish and geese is about 30% higher than that of fish and geese.

First, the benefits of three-dimensional culture of fish and geese.

1. Goose is a fully automatic energy-saving and efficient aerator for fish ponds. When mixed culture of fish and geese, breeders do not need to worry about the lack of oxygen caused by weather change, because in the event of climate change, geese will jump into the water to take a bath and chase, causing spray to tumble. It has a particularly good effect on increasing oxygen in fish ponds.

2. Geese provide high quality bait for farmed fish. Geese are herbivorous birds, and there are many nutrients in goose feces, which are not only the bait of omnivorous fish, but also the high-quality fertilizer of plankton in ponds. If goose manure is dispersed into the pond and decomposed by microorganisms for fish to eat, it can not only save feed, but also reduce the cost of breeding. With the combination of fish and goose, one goose produces 120 to 150 kilograms of dung per year, which can be converted into 5 kilograms of fish, and 50 geese can be raised on each mu of water.

3. Fish ponds provide a clean environment for @ # @ 232 fish ponds. Geese are waterfowl, and the success rate of adult breeding geese in water is significantly higher than that on the ground. Stocking geese on the water surface can lower their body temperature in summer, making them maintain a good spirit and appetite.

Second, the form of comprehensive culture of fish and geese.

1. Raise geese outside the pond. Build a goose house near the fish pond and set up a goose activity place and a waste pool outside the house. Every day, goose dung and goose spilled feed are swept into the active pond, and then flow into the fish pond through the floodgates of the wastewater pond. Raising geese outside the pond is easy to manage, but it can not give full play to the mutually beneficial relationship between fish and geese.

2. Fish and goose co-culture. Build a goose house on the dike ridge of the fish pond, use part of the dike surface and the pond slope as the goose activity field, and surround the fish pond with a net around a certain area of the fish pond as the goose swimming ground, and the arch net in the water is not arched to the end, so that the fish can swim in from the bottom of the net to feed, which is better than putting the goose in the whole pond, because it has less interference to the fish and is easy to manage. Generally, the Internet is 40-50 cm above the surface of the water, and 40 cm from the bottom of the water. The average density of raising geese is 3-5 / square meter in goose house and activity field, and 2-3 in swimming pool. The number of geese in the co-culture of fish and geese is mainly determined by the fecal capacity of geese. Generally, a goose produces 120-150 kg of feces per mu, which can be matched with 50-60 geese per mu.
