The Basics Of Keeping Koi

By Owen Jones


Are you thinking about putting a koi carp pond in your garden? A koi fish pond is a great improvement to any garden. A garden pond is completely relaxing: watching the fish going about their every day lives is relaxing and listening to the sound of the water moving is relaxing as well. Koi carp are a good choice over some other fish because they grow quite large and breed freely even in captivity.

They are not that problematic to keep either. As with all fish ponds, you need to maintain the quality of the water, but that is not so much of a problem when you know what you are doing. Once you have got the water correct, the rest will follow more or less on its own, although you will have to check it frequently.

Having said that, you should not only rush out in to the garden, dig a hole and fill it with fish. You need to buff up on the subject first, but there is so much information on koi on the market, that you will have no difficulty in that regard. There is also lots of knowledge on the Net.

The first thing to do is dig a hole for your pond, but it better not to have it consistently deep. It should be three or four feet deep at one end and a foot or so deep at the other. The koi will overwinter and sleep in the deeper water, but only the fry will feel comfortable in the shallow end. They will take refuge there to avoid being eaten by the larger fish. Like most fish, koi are cannibals.

Once your pond has been dug out, fill it with water and leave it for a week. Use this week to test your water features such as the water pumps, the filter and the fountain. If you are losing water strive to plug the leak. If you have to keep topping up the water level from the hosepipe, you will probably run into hardship with chlorine.

After a week, the chlorine in the tap water will have dissipated and any excess oil in your pond equipment will have been washed out, so you can put aquatic plants in. Plant them in pots so that you can move them easily if necessary. You ought to also construct some underwater caves for the fish to conceal themselves in.

Once you are satisfied that everything is working well and that the environment is stable (this is easier to do in larger ponds), you can think about buying some koi.

You have to make a decision why you want to have koi. Do you want to show them and possibly make some money? In that case you will have to start with costly fish, but if you just want to sit and watch them, the cheapest ones are OK. You can probably ask a friend to give you a few anyway.

If you procure your fish in the breeding season, you will probably get a couple of gravid (pregnant) females anyway.

A word of warning: fish normalize their environment better than we do. A given amount of water will only hold a precise number of inches of fish. So, as an example, say that each ten gallons of water will be sufficient for ten inches of fish and you have 200 gallons that is 200 inches of fish, which is 20 x 10 inch fish or 40 x 5 inch fish. As the fish grow, they will die to maintain this ratio, so do not purchase too many until you are familiar with the ratio.
