age, growth, and weight relationships of
channel catfish (Ictalurus punctatus)
collected from Colorado waters. Colorado
Division of Wildlife, Denver. 13 pp.
Age, growth, and weight data from 565 specimens
of age groups 0-X, from six rivers and six
irrigation impoundments are considered in this
paper. Growth of channel catfish from Colorado
waters varied widely. Fish from western streams
showed the slowest growth rate. Fish from
eastern streams compared favorably with fish
from the Mississippi River in Iowa. Catfish
were introduced at Moab, Utah in the early
1900's. Catfish have found suitable habitat in
most Colorado waters.

The objective of the study was to locate and
determine the extent and nature of water pollu-
tion existing in Utah from June 1 to October 1,
1958. Virtually all the waters of Utah were
found to contain either industrial or domestic
pollution or both in varying degrees of intensity.
The Colorado, San Juan, Green, White, Duchesne,
Price, Bear, Malads, Logan, Weber, Ogden,
Sevier, and Virgin rivers are discussed. A
good review of domestic and industrial pollution
problems in Utah in 1958.

The present study was proposed to focus on the
two rare species of the Colorado squawfish
(Ptychocheilus lucius) and the humpback sucker
