Photo: NORTHLAND REGIONAL COUNCIL SQUIRT ALERT Anyone with a moored boat can avoid spreading marine pests by: Regularly cleaning your boat's hull -- keep fouling growth to no more than a light slime layer. Regularly wiping down the submerged surfaces with a soft cloth will achieve this, and will ensure your antifoul paint remains effective for longer Applying coatings of antifouling paint regularly Ensuring your hull is clean and free of fouling before you travel to a new region, which may involve simply wiping down the submerged surfaces with a soft cloth Inspecting boat areas that retain water in case they're harbouring marine life Cleaning and drying any marine equipment before using it in a new location A tiny troublemaker has turned up in Pauatahanui Inlet, and the regional council is calling on boaties to aid in its containment. An invasive foreign sea squirt, styela clava, has been found in the estuary. It has the potential to change parts of the marine environment, foul boats and be an impediment for marine farm- ing, says Greater Wellington biosecurity manager Davor Bejakovich. But vigilance by boaties could stop it from spreading further and becoming a region-wide nuisance. By simply keeping the hulls of their moored boats clean and well antifouled, vessel owners can help prevent the spread of this pest to other areas,'' he said. Styela clava, also known as the clubbed tunicate, leathery sea squirt, or Pacific rough sea squirt, is thought to originate from the Northwest Pacific. It has a long, club-shaped body on a tough stalk and grows up to 16cm. Its surface is tough, leath- ery, rumpled, and nobbly. They can be brownish-white, yellowish-brown, or reddish- brown. Styela clava is a solitary'' sea squirt, which means that each individual has its own stalk to attach itself to rocks, boats, wharves or any other structure in the sea. It can crowd out native marine plants and ani- mals and filter feeds on large amounts of plankton that native species normally eat. It was first found in New Zea- land in 2005 in Auckland and has turned up at a number of ports since. The Ministry for Pri- mary Industries led a pro- gramme to scope out its spread and attempt to remove it. It was found that it was not technically feasible to eradicate. We can all do our bit to make sure it doesn't spread to marine farms or high valued biodiver- sity areas like marine reserves, or around the country in gen- eral,'' said Mr Bejakovich.
