Sturgeon are a family of ancient fish, and one of the oldest families of bony fish in existence. They appeared in the fossil record around 200 million years ago, and have undergone very little morphological change.They will require a large pond, with well oxygenated water. Sturgeon may get entangled in blanketweed, often with fatal consequences.Sturgeon are a bottom feeding fish and should be fed sinking food. Because they come from cooler climates, sturgeon have a higher metabolism than other pond fish during the winter months and require feeding for longer periods through the year. All sturgeon are non-native and it is illegal to release them into the wild in the UK.
