As of 2020, based on 3 circulating water culture tanks, the annual operating cost requires 1 to 1.2 million strong> (this includes: construction of circulating water foundations, installation of complete equipment, seeds, feed, etc.).
Normally, it takes 8 to 10 acres to build one aquarium, and three aquariums take about 25 to 30 acres. It will take about 250,000 to 300,000 yuan to complete the infrastructure and breeding equipment. Each aquarium costs between 80,000 and 100,000 RMB, and many of them are shared systems, so the more aquariums you build, the more cost-effective it is. One tank (200 cubic meters) can raise about 60,000 kilograms of grass carp, 70,000 to 80,000 kilograms of carp, more than 20,000 kilograms of perch, more than 30,000 kilograms of catfish and more than 30,000 kilograms of crucian carp.
Each variety is different. Furthermore, diDifferent varieties and levels of breeding technology have different yields. There are no special requirements for the pond, provided that it is free from pollution and meets the standards for fish farming water bodies.

Attention
Selection of cultivated species
Aquaculture in circulation is not not limited by region and temperature limit, your choice can be closer to the market. It is best to do market research first. Understand the market scope that fish farming can reach, go to these fish markets, supermarkets and hotels, contact the fish in these markets and understand the species and consumption, as well as the consumption cycle, low and high seasons , etc.
Check the seed supply of this variety, as having good seeds is half the battle. Furthermore, circulating aquaculture does notis not limited in time and reproduction can begin at any time to avoid market time differences. This requires the seed supply to also be flexible enough to provide a continuous supply when you need it. It’s a safe bet to consult several nurseries as alternatives.
Solar water can be used to raise fish, but sometimes the temperature of solar water is extremely high, sometimes even reaching over 95 degrees. The temperature suddenly rises. Changes are most likely to occur. cause fish to catch cold and die, so try not to use it to raise fish.
In normal water changes for goldfish, especially in hot summers, you only need to insist every day to remove feces and dirt at the bottom of the fish pond ( aquarium) with the old water, and d'use a hose to gently suck 1/10-1/5. Remove dust and floating feces from the water surface,
then slowly inject new isothermal water along the wall of the pool (tank) to keep the water clean. This water changing method is not easy to harm the fish body, is simple and safe, and is especially suitable for fish keepers in home aquariums or small ponds.

Bait placement
p>
Adhere to the three principles of bait feeding, qualitative: high protein, fresh and clean; quantitative: pay attention to when the goldfish in the pond eat each time, it is generally appropriate to finish eating within 20-30 minutes; timing: morning in summer Around seven o'clock, around three o'clock in the afternoon, in winter, as the fish swim less, we can feed onetimes around noon. ?
It should be noted that every time you feed, you should feed enough at a time, and you should add duckweed or a small amount of pellets appropriately according to the feed. fish appetite in the yard. agriculture is mainly The synthetic pellet feed used is a very good auxiliary feed, and it is also the best substitute when natural feed is scarce.
