Effect of pH on the accumulation kinetics of pentachlorophenol in goldfish Effect of pH on the accumulation kinetics of pentachlorophenol in goldfish
The kinetics of accumulation of pentachlorophenol (PCP) at various pH values were investigated to explore how pH-dependent accumulation might influence PCP toxicity. Goldfish (Carassius auratus) were exposed to 5 μg PCP/L in a static system buffered with 7.5 mM bicine orN,N-bis(2-hydroxyethyl)-2-aminoethane sulfonic acid (BES) at pH 7.0, 8.0, or 9.0. The amount of PCP in the fish...

Egg size and laying order of snowy egrets, great egrets, and black-crowned night-herons Egg size and laying order of snowy egrets, great egrets, and black-crowned night-herons
The authors' objective was to describe egg size in relation to laying order for Great Egrets (Casmerodius albus ), Snowy Egrets (Egretta thula ), and Black-crowned Night-Herons (Nycticorax nycticorax ) in a southern Texas colony and Great Egrets in a southern Florida colony. Based on egg-size patterns in other colonial waterbirds and the occurrence of brood reduction in egrets and herons...

Mercury accumulation in yellow perch in Wisconsin seepage lakes: Relation to lake characteristics Mercury accumulation in yellow perch in Wisconsin seepage lakes: Relation to lake characteristics
We studied relations between lacustrine characteristics and the total mercury (Hg) content of calendar age-2 yellow perch (Perca flavescens) in 10 seepage lakes in north-central Wisconsin. Mean concentrations and burdens (masses) of Hg in whole perch varied widely among lakes, were negatively correlated with lake pH and were positively correlated with total Hg concentration in surficial...

Benefit-cost analysis of fishery rehabilitation projects: A Great Lakes case study Benefit-cost analysis of fishery rehabilitation projects: A Great Lakes case study
Tools of benefit-cost analysis are used to evaluate a project to rehabilitate the yellow perch fishery of Green Bay, Wisconsin. Both sport and commercial fishers harvest from this stock, which has been suffering from much reduced productivity since the early 1960s. The project is composed of commercial quotas and other regulations. Measures of benefits and costs were used that explicitly

Whole body and tissue blood volumes of two strains of rainbow trout (Oncorhynchus mykiss) Whole body and tissue blood volumes of two strains of rainbow trout (Oncorhynchus mykiss)
1. Estimates of apparent packed cell, plasma and total blood volumes for the whole body and for 13 selected tissues were compared between Kamloops and Wytheville strains of rainbow trout (Oncorhynchus mykiss) by the simultaneous injection of two vascular tracers, radiolabeled trout erythrocytes (51Cr-RBC) and radioiodated bovine serum albumin (125I-BSA). 2. Whole body total blood volume...

The difference between the potentiometric surfaces of the Magothy Aquifer of September 1986 and September 1988 in southern Maryland The difference between the potentiometric surfaces of the Magothy Aquifer of September 1986 and September 1988 in southern Maryland
A map was prepared that shows the net change in the potentiometric surface of the Magothy aquifer (in the Cretaceous Magothy Formation) in southern Maryland from the fall of 1986 to the fall of 1988. The map, based on water level measurements from 79 observation wells, shows that during the 2 year period the potentiometric surface declined less than 5 ft in most of the northern part of...

Selected data for stream subbasins in the Watonwan River basin, south-central Minnesota Selected data for stream subbasins in the Watonwan River basin, south-central Minnesota
This report presents selected data that describe the characteristics of stream basins upstream from selected points on streams in the Watonwan River basin. The points on the streams include outlets of subbasins of about five square miles, sewage treatment plant outlets, and U.S. Geological Survey streamflow-gaging stations in the basin.
