Statements all about Barnacles
Barnacles are a shell species which release millions of larvae. The animals attach themselves to solid, non moving objects, such as docked boats, where they can absorb nutrients that float through the water. Boat hulls are also fertile grounds for algae and other growth. Barnacles are particularly familiar to boat-owners, who usually detest them because they settle on the bottom of boats slowing down the speed of the boat,
Shell-fouling microscopic organisms are hatched in the sea. They swim around until they find a nice neighborhood (your boat bottom) to attach themselves to. The most common shell-fouling organism is the Acorn Barnacle. There are a variety of species that can grow to a whopping 7 centimeters in diameter.
Zebra mussels usually reach reproductive maturity by the end of their first year. Reproduction occurs through spawning when sperm and eggs are released into the water. Spawning peaks at water temperatures of about 68 degrees F. A fertilized egg results in a free-swimming, planktonic larva called a ‘veliger.’ This veliger remains suspended in the water column for one to five weeks, and then begins to sink, eventually attaching to a stable surface (e.g., rocks, dock pilings, aquatic weeds, water intakes, boat hulls) on which to live, grow and reproduce. They attach to these surfaces using adhesive structures called byssal threads.
When barnacles adhere to the bottom of a boat, they continually grow and exert considerable pressure at the point of attachment. These creatures enjoy their resting place so much that even when removed, they leave a strong foundation, commonly called "husks." The adhesion of the husks is so great that the force necessary to remove them can tear the gelcoat, causing more damage.
The barnacle — known to grow at least as large as a woman’s palm — is seen as a potential “fouling” nuisance, because barnacles can cement themselves to everything from boat hulls to intake pipes.
It is also a problem for vessels: fouling can
raise costs for owners due to increased maintenance, decreased fuel efficiency
and blocked or damaged internal pipes.
"The zebra mussels pose an alarming threat because they are very prolific reproducers," Clarke said, "and they have no natural predators to help control their numbers."
Adult zebra mussels, which can live 10 to 15 days out of water, attach themselves to boat hulls, trailers or outboard motors.
