Summary 1. Fisheries models generally are based on the concept that strong density dependence exists in fish populations. Nonetheless, there are few examples of long-term density dependence in fish populations. 2. Using an information theoretical app

It has been suggested that the genetic growth potential of trout may be degraded over time by differential angler harvest of the faster-growing fish of each cohort. To test this hypothesis, young-of-the-year wild brook trout Salvelinus fontinalis fro

The average hooking mortality per capture event for 630 trophy-sized wild brook trout Salvelinus fontinalis (mean total length, 33.9 cm) caught on five hardware lures was 4.3% during the first 48 h after capture, Mortality was 8.3% for brook trout ca

Techniques for erosion control such as stream-bank stabilization and revegetation of eroding upland areas reduce only part of a stream's sediment load. This study on Poplar Creek in Michigan (one of two papers) demonstrated that an in-stream sediment

This is the second of a two-part sedimentation study. A sediment basin excavated in a Michigan trout stream reduced the sandy bedload sediment by 86% (from 56 ppm down to 8 ppm). Following the reduction in bedload, trout numbers increased significant

A modification of the inclined-screen trap was constructed to capture and facilitate processing of runs of salmonid smolts in large rivers. Modifications included a hanging inclined screen, a floating catch barge, and a fish sorter. Two such traps op

An experimental introduction of sand sediment into Hunt Creek in the northern Lower Peninsula of Michigan that increased the bed load 4-5 times resulted in a significant reduction of brook trout (Salvelinus fontinalis) numbers and habitat. The brook

Since establishment of the Board of Fish Commissioners in 1873, the trend in Michigan trout fishing regulations has been toward more restrictive and complex laws. Major scientific investigations concerning the effectiveness of various types of regula

A mathematical model of trout-stream fisheries was developed that can be used to evaluate a variety of fishing regulations. Density-dependent mortality was found in the first 2 years of life for each of the two brook trout (Salvelinus fontinalis) and

The objective of this experiment was to compare angling quality for various sizes of trout in stream sections having two different sets of fishing regulations. Four anglers fished artificial flies and worm-baited hooks equal amounts of time in two st
