Genetic effects of hatchery rearing in Atlantic salmon
Aquaculture, 1983Abstract Six polymorphic enzyme loci were examined electrophoretically in a sample of wild Atalntic salmon smolts from the Burrishoole river in western Ireland and in samples of artificially-reared fry hatched in 1981 and parr hatched in 1979. These hatchery reared fish were the progeny of five generations of artificially reared sea ranched salmon ...

Supplementation of wild salmon stocks: A cure for the hatchery problem or more problem hatcheries?
Coastal Management, 1995Supplementation is a hatchery technology that attempts to correct for many of the problems associated with traditional hatcheries. Indian tribes along the Columbia River plan to use this technology to restore many of the badly damaged runs in the basin.

The use of hatchery technology for the conservation of Pacific and Atlantic salmon
Reviews in Fish Biology and Fisheries, 2013Hatchery technology has been employed for the conservation of Pacific (Oncorhynchus spp.) and Atlantic salmon (Salmo salar) for over 140 years. The initial societal paradigm was that nature is inefficient and hatcheries could be used to conserve stocks that were over utilized or suffering habitat degradation.

Salmon Smolt Tagging Experiments at Invergarry Salmon Hatchery
1959In September 1955 preliminary tests to determine the efficiency of various types of tag was carried out on salmon parr in the ponds of the salmon hatchery at Invergarry (Inverness-shire, Scotland).This publication is part of Rapport et Proces-Verbaux des Reunions Vol. 148.

Extended Freshwater Rearing of Pink Salmon at a Washington Hatchery
The Progressive Fish-Culturist, 1978Abstract Many fish culturists believe that after incubation and 45 days of fresh water rearing, smolts of pink salmon (Oncorhynchus gorbuscha) must then be further reared at salinities of 15 to 25 ‰ until they are stocked. We monitored the rearing of 50,000 pink salmon of the 1971 brood in fresh water for 135 days.

Predation on Chinook Salmon Parr by Hatchery Salmonids and Fallfish in the Salmon River, New York
North American Journal of Fisheries Management, 2016Abstract Naturally reproduced Chinook Salmon Oncorhynchus tshawytscha contribute substantially to the fishery in Lake Ontario. The Salmon River, a Lake Ontario tributary in New York, produces the largest numbers of naturally spawned Chinook Salmon, with parr abundance in the river often exceeding 10 million.

A review of homing and straying of wild and hatchery-produced salmon
Fisheries Research, 1993Abstract This paper reviews studies on the patterns of straying of adult salmonids from their river or hatchery of origin, with emphasis on Pacific salmon. The prevalence of straying varies greatly among populations. In general, introduced (i.e. non-native) populations and salmon displaced from their rearing site for release stray more than native ...

Transactions of the American Fisheries Society, 1992
Abstract -Large numbers of spiny dogfish Squalus acanthias moved into the area near the mouth of the Big Qualicum River, British Columbia, at the time hatchery-reared smolts of Chinook salmon Oncorhynchus tshawytscha and coho salmon O. kisutch were leaving the river in 1988 and 1989. A small percentage of the spiny dogfish preyed on the smolts, but the

The Creation of the First Public Salmon Hatchery in the United States
Fisheries, 2000Abstract The first public salmon hatchery in the United States was constructed in 1871 at what was then known as Craig's Pond Brook, Maine. Funded by a consortium of northeastern states, the eggs and juveniles reared at the hatchery were intended to assist rehabilitation of depressed runs of wild Atlantic salmon (Salmo salar) in New England.
