We tracked three groups of steelhead Oncorhynchus mykiss smolts implanted with acoustic transmitters to determine whether the degree of hatchery domestication or the juvenile rearing environment (hatchery raceway versus natural stream) influenced mig

The ratio of RNA to DNA (RNA:DNA) in white muscle tissue of juvenile summer flounder ( Paralichthys dentatus ) and weakfish ( Cynoscion regalis ) was used as a proxy for recent growth rate in an estuarine nursery. Variability in RNA:DNA was examined

The live body mass, body volume, and length were determined for four groups of juvenile plaice (Pleuronectes platessa L.): (1) plaice immigrating into the Wadden Sea, (2) fish that had settled in the Wadden Sea, (3) settled fish that had been starved

Sampling with nets or trawls remains a common technique for determining the comparative abundances of aquatic organisms, and the objective of such studies is frequently to evaluate relationships among the counts of individuals caught and exogenous va

Archimedes' principle can be effectively applied to measure the mass and volume of small aquatic organisms by weighing the organism in waters of two densities, and then comparing those values with the weights of a plummet weighed in the same waters.

The transport of plankters by water currents is acknowledged to have an important influ- ence on observations of organism abundance and population processes, but assessment of this effect has been difficult to achieve. This paper presents simulations

Spatial and temporal patterns of dissolved oxygen (DO) in Yaquina Estuary, Oregon (USA) are examined using historic and recent data. There was a significant increasing trend in DO in the upstream portion of the estuary during the years 1960–1985. H

We measured growth of larval Atlantic menhaden, Brevoortia tyrannus in terms of mass, volume, and weight in water as well as the mass-specific activities of the metabolic enzymes citrate synthase, lactate dehydrogenase, and malate dehydrogenase. Weig

A microbalance is used to weigh animals while they are immersed in water held at constant temperature. Paired weighings of the same individual, done in waters of identical osmolality but differing in density, permit the use of Archimedes' principle t

Many species appear to selectively use tidal currents for transport into or out of estuaries, or to maintain residence within an estuary. Further, some species are preferentially active during nocturnal hours, possibly to reduce their vulnerability t
