Biology of the Crayfish Orconectes Causeyi and Its Use for Control of Aquatic Weeds in Trout Lakes
Author: Jack L. Dean
Publisher:
ISBN:
Category : Aquatic weeds
Languages : en
Pages : 20
Book Description
Sumerged aquatic plants limit the suitability for trout management of many shallow lakes in the Southwest. Control of these weeds has been achieved by the introduced crayfish Orconectes causeyi. The life history, ecology, and weed-control activities of the crayfish are discussed. Abundant crayfish populations occur over a wide range of elevations in permanent well-oxygenated ponds, lakes and streams where predaceous warm-water fishes are scarce. Weed control is proportional to the crayfish population and proximity of a rocky substrate which is preferred habitat. This crayfish is a tertiary burrower establishing relatively shallow burrows for hibernation and egg hatching periods. It has not damaged dams or irrigation ditches and has been compatible with local agriculture.

Marking Fish with Dyes and Other Chemicals
Author: Dean E. Arnold
Publisher:
ISBN:
Category : Fish tagging
Languages : en
Pages : 46
Book Description
The literature on marking fish with chemicals is reviewed, with critical commentary and suggestions for desirable areas of research. A variety of substances have been used to mark aquatic animals by methods such as deep injection, subcutaneous injection, tattooing, immersuion, daubing, and feeding. Over 100 dyes and other chemicals that have been used for marking aquatic animals are listed and the results of published or unpublished experiments using each one are summarized. A bibliography of over 150 titles is given.
