The more you understand about any subject, the more interesting it becomes. As you read this article you'll find that the subject of asian food is certainly no exception. The fear for snakeheads has its basis in the fact that they are ferocious predators that can swallow fish of half their own size. This has meant that many now fear that Snakeheads could do massive damage to the eco systems if the where ever to establish themselves in the US. A result of this fear is the ban to import snakeheads that was imposed 2003. This has however not stopped live snakeheads from being available in Asian food markets and the aquarium trade. I trust that what you've read so far has been informative. The following section should go a long way toward clearing up any uncertainty that may remain. They are originally found in Africa and South East Asia where they are appreciated food sources. Snakeheads vary in size from very small to very large. The largest species can reach over one yard (almost one meter) in length. Snakeheads differ from many other fishes due to the fact that they breathe air by using something called a labyrinth which enables them to consume oxygen from the atmosphere. This means that they can live for long periods on land as long as they can stay moist. They use this ability to walk to new areas to live and feed in. Snakeheads drown if they can’t access the surface to get air. They are popular aquarium fishes and many aquarists are opposing the decision to ban snakeheads and believe that snakehead import for the aquarium trade should be allowed. They believe that import at the very least should be permitted in colder states where snakeheads can’t survive in the wild. They have a point in this believe since snakeheads re unable to survive in most areas in the USA due to the fact that they need warm water to survive. Allowing snakehead import in some states will however make it harder to enforce the ban in the states where they could survive which could serve to justify the nation wide ban. Now might be a good time to write down the main points covered above. The act of putting it down on paper will help you remember what's important about asian food.
