Population Recovery and Natural Recruitment of Lake Trout at Gull Island Shoal, Lake Superior, 1964–1992

Stephen T. Schram, +3 more
- 01 Jan 1995 - 
TL;DR: After 28 years of recovery the Gull Island Shoal lake trout population appears to have additional capacity to increase because the stock-recruitment relationship is still linear, and restoration periods on the order of 30 years may be needed for other lake trout populations in the Great Lakes.

Test of a Model of Regulation of Crown-of-Thorns Starfish by Fish Predators

Rupert Ormond, +7 more
TL;DR: The hypothesis that current and recent outbreaks of the crown-of-thorns starfish on the Great Barrier Reef have been facilitated by the presence of only relatively low numbers of fish predators, the numbers of which may have been decreased as a result of the intensification of fishing pressure that has occurred from the 1960s onwards is supported.

Size Selectivity and Bias in Estimates of Population Statistics of Smallmouth Bass, Walleye, and Northern Squawfish in a Columbia River Reservoir

Raymond C. Beamesderfer, +1 more
- 01 Nov 1988 - 
TL;DR: In this paper, the authors describe size selectivity of five types of gear and potential bias in estimates of population statistics of smallmouth bass, walleye, Stizostedion vitreum, and northern squawfish in John Day Reservoir on the Columbia River.

Influence of Habitat Type on Food Supply, Selectivity, and Diet Overlap of Bonneville Cutthroat Trout and Nonnative Brook Trout in Beaver Creek, Idaho

Robert H. Hilderbrand, +1 more
- 01 Feb 2004 - 
TL;DR: In invertebrate drift samples and stomach contents of native Bonneville cutthroat trout and nonnative brook trout in Beaver Creek, Idaho, during August 1995, aquatic Diptera numerically dominated drifting invertebrates by at least fivefold over all other categories captured in 1-h drift samples.
Journal ArticleDOI

Comparative demography of two populations of the bonnethead shark (Sphyrna tiburo)

Enric Cortés, +1 more
- 01 Apr 1996 - 
TL;DR: La composition par âge stable prevue, l'esperance moyenne de vivre plus longtemps and the valeur de reproduction pour des femelles des deux populations etaient semblables.
