Excerpt from Nature and Extent of Fouling of Ships' Bottoms It is the practice of most shippmg concerns to' 'clean the bottoms of their vessels every six or eight months In or'dei' to do this the bottoms are exposed to view, either by the use of dry docks or marine railways. -the' former are of two types - the granng dry dock and the floating dry dock: Lighter ci'aft frequently are removed from the water by a marine railway. The dost. Of maintaining and operating such equipment can be charged largely to fouling The large sums of money involved can be realized When one learns that it costs approximately $100, 000 to dry-dock, clean, and paint the bottom of a vessel s11'ch as the Leviathan or the Majestic, for these ships have more than an acre of surface exposed to the action of the sea and Which must be cleaned'. And painted' every time these vessels are dry docked. It must not be forgotten, also, that during the period 111 dry dock the cost of maintaining the ship and its crew remains constant, While the operating income is reduced to nothing. The time spent 111-dry dock varies With conditions from three days to three weeks, or more; but for the ships listed in this report the average is seven or eight days.

Recent instances of bioinvasion, such as the emergence of the zebra mussel in the American Great Lakes, generated a demand among marine biologists and ecologists for groundbreaking new references that detail how organisms colonize hard substrates, and how to prevent damaging biomass concentrations.

In The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.
