Hull fouling


Did you know?

A single mussel, at one month of age and 10 mm in length can produce 50,000 offspring. If each baby mussel survived for one month and reached one centimeter in length, the resulting biomass would be around 50 kilograms.

Many species of marine animals and plants are specialist at gluing themselves onto rocks pounded by thunderous waves. Some of these animals can also survive on the hulls of ships with their extraordinary glue. Some can even live on the shells of turtles or the skin of whales.

When plants and animals live on the hulls of boats and ships it is called fouling. Fouling has been a major problem for all ships including the first ships built centuries ago. The marine life living on the hull slows the ship down and can also damage the hull.

Most of the 250 plants and animals that have hitched ship ride to Australia have come on ship hulls or fittings.
