Schmitt, C.J.; Ribick, M.A.; Ludke, J. L.; May, T.W. Reproduction by the endangered cui-ui in the lower Truckee River
Adult spawning behavior and emigration of larvae of the endangered cui-ui Chasmistes cujus were studied in a natural side channel of the lower Truckee River. External radio-tags placed on eight apparently did not affect spawning behavior. Cui-uis spawned in clusters of two to seven fish; usually a single female was flanked by two males. Each...
Scoppettone, G.G.; Wedemeyer, Gary; Coleman, M.; Burge, H. The effects of meiofauna on settling macrofauna: meiofauna may structure macrofaunal communities
When macrofaunal larvae and juveniles recruit into the benthos, they are in the same size category as the meiofauna. These small size classes have been consistently ignored in macrofaunal studies despite the increasingly accepted idea that communities are structured not only by interactions between adults, but also by interactions which...
Watzin, Mary C. Accumulation, sublethal effects, and safe concentration of a refined oil as evaluated with cutthroat trout
Cutthroat trout (Salmo clarki) were exposed for 90 days in the laboratory to a refined oil collected from the North Platte River at a seepage site below the American Oil Company refinery at Casper, Wyoming. Fish were exposed to five concentrations and a control, and seven biological responses (survival, growth, gill pathology, liver pathology,...
Woodward, D.F.; Riley, R.G.; Smith, C. E. The role of the USFWS geographic information system in coastal decisionmaking
Unprecedented demand on coastal resources in the 1980's has generated a need for valid information and analyses to support wise management of the coastal zone. The National Coastal Ecosystems Team of the U.S. Fish and Wildlife Service recently implemented a geographic information system to enhance its ability to analyze and display environmental...
Ader, Robert; Stayner, Floyd O. COASTAL*FISH user's guide--a finfish/shellfish information base for Mississippi Sound and Mobile Bay
COASTAL *FISH is a computerized database that includes current information on spawning, nursery areas, migrations, distribution, and environmental requirements of finfish and shellfish. This User's Guide was prepared to access and query the finfish and shell fish database. It provides basic information required to query the database.

Ader, Robert; Johnston, James B. Some observations on the ecology and fish management of reservoirs in the United States
By 1980 there were 1,608 reservoirs (over 202 ha each) with a surface area of 4 million ha in the United States. Construction of new reservoirs has decreased in recent years because of the lack of suitable sites and the opposition of environmental interests. Reservoirs have characteristics of both lacustrine and riverine ecosystems. Reservoirs...
