Book Description
Excerpt from Distributions of Fishes in Fresh Water of Katmai National Monument, Alaska, and Their Zoogeographical Implications Only one species in Naknek Lake, Arctic grayling, does not occur in the Coville -gros venor Lakes complex (table Three anad romous fishes, pink, churn, and chinook salmon, occur only rarely in this area. The absence of grayling in these lakes is puzzling because no major physical barriers exist between Grosvenor and Naknek Lakes, and the Grosvenor River and lower American Creek appear to be excellent grayling habitat. If gray ling are a relatively late arrival and still in the process of dispersal in the system, cau tious speculation suggests that their dispersal may be limited by the extreme turbidity of Iliuk Arm and Savonoski River. The general distribution and abundance of grayling in the system are limited, and no large numbers of this species are available to probe routinely through adverse environments. Other more complex environmental factors may be limiting grayling distribution in the system. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
