Although seldom achieving their full potential many of the Sturgeon species kept in our garden ponds can still reach a spectacular size, especially when compared to the more common species of Comet Goldfish and Koi.
The commonest species, the Siberian Sturgeon, (Acipenser baerii), will often get to 1.2M and 20Kg, and whilst well short of the maximum wild size of 2M and 200Kg, still a big pond fish. Larger still are the Diamond Sturgeon, (Acpenser gueldenstaedtii), which can reach 2.5M in the wild and around 1.5M in your pond. And finally, for us at least, and the main reason for building our new pond, is the Atlantic Sturgeon, (Acipenser oxyrinchus), weighing in at 15 feet and over 800 pounds. Even if ours only get to half that size it will be something to see.
Requiring good, well oxygenated water, plenty of swimming space and lots of food we were finding that even our large pond vats were getting a little crowded for the sturgeon that we had in stock, so we set about designing a pond specifically to house these big fish.
Obviously the bigger the better, but unlike most people we still need to be able to catch these fish for sale to customers, which limits our width to about 12'. Any wider and you can't reach the middle with a net man on each side and spend all day just chasing the fish around and around. Length is not really an issue, although if you have ever tried to manoeuvre very big pond liners you will appreciate that there are practical limits.
Depth is easy, its determined by the size of the digger and the skill of the driver. So there you have it, all very scientific, twice the width a man can reach with a long handled net multiplied by the length of the biggest piece of liner you can lift multiplied by how deep you can reach with your excavator = how much water it will hold.
I' am sure some of you will have already worked it out in your head, but for those of you who are not so good at mental arithmetic its all explained on the next page
