The spiny-cheeked crayfish was found in the park in 2005. The first one may have arrived on a contaminated fishing vessel. Crayfish are foreign to Bluenose waters, but fishermen from other areas might have unknowingly brought in the eggs, said Jonah Mitchell, manager of resource conservation at the park. Freshwater mussels, snails and trout could be vulnerable to the increased competition for food and shelter, Mr. Mitchell said. About 45 crayfish were trapped last summer to reduce their population, but their numbers have only kept climbing. Parks Canada staff trapped more than 500 of the spiny critters in July. "They're pretty voracious," Mr. Mitchell said. --------------050609080405050505040902 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: 7bit <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta content="text/html;charset=ISO-8859-1" http-equiv="Content-Type"> <title></title> </head> <body bgcolor="#ffffff" text="#000000"> <font class="Content_Headlines-links">CRAYFISH CAUSING PROBLEMS (The Chronicle Her.ld, August 30, 2007)</font><br> <br> By LAURA FRASER Cape Breton Bureau <font class="Content_body-links"> <p>INGONISH — An exotic species has penetrated the depths of Freshwater Lake in Cape Breton Highlands National Park, and staff say it may harm native plant and animal populations. </p> <p>The spiny-cheeked crayfish was found in the park in 2005. </p> <p>The first one may have arrived on a contaminated fishing vessel. </p> <p>Crayfish are foreign to Bluenose waters, but fishermen from other areas might have unknowingly brought in the eggs, said Jonah Mitchell, manager of resource conservation at the park. </p> <p>Freshwater mussels, snails and trout could be vulnerable to the increased competition for food and shelter, Mr. Mitchell said. </p> <p>About 45 crayfish were trapped last summer to reduce their population, but their numbers have only kept climbing.
