REPORT ON MARINE BORERS AND FOULING ORGANISMS IN 56 IMPORTANT HARBORS AND TABULAR SUMMARIES OF MARINE BORER DATA FROM 160 WIDESPREAD LOCATIONS

摘要

Every year millions of dollars' worth of marine structures are damaged by marine borers of various kinds. They bore into and may eventually destroy not only timber, but also low-grade concrete, soft stone, and other nonmetallic materials in salt water. No salt-water port in the world is entirely safe from their depredations, except perhaps where the water is extremely diluted with fresh water or is heavily polluted with acids, oils, or other industrial wastes. Even heavily creosoted wood is not immune from Limnoria, the most widely distributed genus of crustacean borer.
