Factors Contributing to the Spread of Snakeheads
Snakeheads can spread through various means, such as their illegal use as bait, unintentional transport in boats, and their remarkable ability to breathe air and survive out of water for days. These factors have contributed to their rapid and widespread establishment in the United States.
Illegal Bait Use
Snakeheads are often used as live bait due to their aggressive nature and large size. However, the use of snakeheads as bait is illegal in many states, as it can lead to their unintentional release into new waterbodies. Anglers using snakeheads as bait may dispose of them improperly, allowing them to enter natural ecosystems and further expand their range.
Unintentional Transport
Unintentional transport plays a significant role in the spread of snakeheads. They can easily hitch a ride on boats, trailers, or fishing equipment, enabling them to be released into new waterbodies far from their original location. This unintentional transport can occur when boaters or anglers unknowingly harbor snakeheads in their gear or when snakeheads cling to boat hulls or live wells.
Breathing Air and Survival out of Water
One of the most unique and concerning attributes of snakeheads is their ability to breathe air and survive out of water for days. This adaptation allows them to travel short distances on land, especially during periods of heavy rainfall when they can migrate to nearby waterbodies. They can also survive in low oxygen or stagnant water, which expands their habitat range and increases their chances of establishing new populations.
Summary
In summary, snakeheads can spread through their illegal use as bait, unintentional transport, and their remarkable ability to breathe air and survive out of water for extended periods. These factors have contributed to their rapid and widespread establishment in the United States, posing a significant threat to native fish populations and the fishing industry. To mitigate the spread of snakeheads, it is crucial to enforce regulations against their use as bait, raise awareness about unintentional transport, and implement measures to prevent their introduction into new waterbodies.
