The Activity of 'Limnoria Tripunctata' in Piling Cut-Offs from Naphthalene-Enriched Creosoted Pilings
Cut-offs from piling treated with creosote plus additional naphthalene at four levels were exposed to Limnoria tripunctata both in the laboratory and in the field. After two years of exposure to active Limnoria attack in the laboratory and in the field, the 10 percent naphthalene additive samples showed the greatest resistance to attack by Limnoria tripunctata. The treatment which showed the least resistance to Limnoria tripunctata under laboratory conditions was the 30 percent additive. The treatment which showed the least resistance to Limnoria tripunctata in the field was the 20 percent additive. Wedges coated with Bitumastic on the cut surface were not as heavily attached by Limnoria as the wedges which were left uncoated. A great deal of variation in the Limnoria attack among wedges of same treatments was observed, especially those cut from diffferent discs. Fouling organisms, especially barnacles were very heavy on discs during the first year of exchange at Dayton Beach, Florida. Molluscan borers, Pholadidae were found in small numbers in discs of all four percentages. None of the samples put on exposure proved to be very effective against attack by Limnoria tripunctata.
