All About Sturgeon
Without doubt sturgeon are most over sold fish on the planet. A bold statement but I have heard they cure every thing from blanket weed to being vacuum cleaners.
Well as most of you have noticed sturgeon are not any of these.
This page is a basic guide to sturgeon. Most of these items are mentioned on other pages but it seems people are unable to find it ( What I mean is people don't want to look for it, they want to know NOW so here it is ). I would suggest you read the rest of the site as it will give a more detailed covering of the subjects.
Sturgeon Like:
Sturgeon need proper food.( Not wheat germ or Cereal based foods. )
Well oxygenated water. Use an airpump through out the summer months to back up the main pump.
Filtered water ( unless in a lake)
A large pond minimum 1000 gallons ( 5000litres) for sterlets.
For other species minimum 2000 gallons.
A back up pump in case of main pump failure.
Sturgeon dislike:
Strong chemicals, formalin, BKC, ( These can be used at a lower dose than you would for Koi, except Formalin with Diamond sturgeon as they generally die a week after treatment ).
Low oxygen, they will die long before other fish, so no ' the other fish are OK' this does not work with sturgeon .
Lack of food, they bend in half and either lie on the bottom or somes times float. If they have got this far it's to late.
Warm weather, this lowers the oxygen level .
Direct sun light, they are dusk till dawn creatures and like the dark best. So have some shade for the fish to shelter under.
Problems.
Nearly all problems are either food or oxygen related, so rather obviously :
Always make sure the oxygen levels are good. ( Buy a test kit they are not expensive. )
Use the correct food.
Malnutrition.
The tell tail signs are:
Fish bends in half. Lack of food , to late time to start digging a grave.
Fish spends all its time bobbing up and down around the edge of the pond. ( Its starving )
Fish follows other fish and tries to suck mucus of the fish. ( Its Starving.)
Oxygen.
This is rather easy the sturgeon become lethargic, and die !
Buy an air pump !
Sturgeon in Aquariums : NO !!!!!! They are not suitable and should not be kept in aquariums or small tanks.
Feeding.
How to feed your sturgeon.
Spring. Sturgeon like any fish become more active in spring as the temperature rises and will need an increase in food, feed alittle and often best times dawn and dusk.
Summer , Sturgeon will be feeding very well in summer so make sure the food is avaliable and the rest of the fish are well fed.
Autumn. Sturgeon will be fattening up for the winter so keep the food going in but watch out and remove uneaten food.
Winter. Feed a few pellets at a time and wait until eaten, before adding more . Sturgeon will feed down to 4C it is very important that you feed them in winter, most sturgeon die due to starvation in winter.
Sturgeon and the Cold. Will sturgeon survive our winters ?
With names like siberian sturgeon , Russian sturgeon this should give it away. Cold is not a problem they will tolerate much colder weather than we will ever get.
