Understanding how the hatchery environment represses or promotes the development of behavioral survival skills
Although great strides have been made in the development of techniques for rearing marine fish, methods for improving survival capabilities following release of these fish into the naturalExpand

Effects of simulated trawling on sablefish and walleye pollock: the role of light intensity, net velocity and towing duration
Laboratory apparatus which simulated capture of fish in the cod-end of a towed trawl was used to induce post-capture stress as measured by alterations in behavioural, physiological and mortalityExpand

The role of learning and stress in predator avoidance of hatchery-reared coho salmon (Oncorhynchus kisutch) juveniles
Abstract The possibility of conditioning hatchery-reared coho salmon ( Oncorhynchus kisutch ) juveniles to avoid predation, and the role of learning and stress in predator avoidance was investigatedExpand

Stress induced by hooking, net towing, elevated sea water temperature and air in sablefish: lack of concordance between mortality and physiological measures of stress
In a series of laboratory studies designed to simulate byeatch processes, sablefish Anoplopoma limbria were either hooked for up to 24 h or lowed in a net for 4 h and then subjected to an abruptExpand

Stress and Delayed Mortality Induced in Pacific Halibut by Exposure to Hooking, Net Towing, Elevated Seawater Temperature and Air: Implications for Management of Bycatch
Abstract The extent of stress and eventual mortality in Pacific halibut Hippoglossus stenolepis that resulted from simulated capture by hooking or towing in a net, followed by abrupt exposure toExpand

Temperature magnified postcapture mortality in adult sablefish after simulated trawling
For sablefish Anoplopoma fimbria that had been transferred abruptly from ambient (5·7° C) to temperatures ranging from 15 to 20° C for 30 min followed by 15 min in air (19·5) C), mortality increasedExpand

Responses by Pacific Halibut to Air Exposure: Lack of Correspondence among Plasma Constituents and Mortality
Abstract Age-1 and age-2 Pacific halibut Hippoglossus stenolepis were exposed to a range of times in air (0–60 min) and air temperatures (10°C or 16°C) that simulated conditions on deck after captureExpand

Behavioural responses of sablefish, Anoplopoma fimbria, to bait odour.
A behavioural bioassay was used to determine the response threshold to squid extract of sablefish, Anoplopoma fimbria, held at three different feeding regimens. Sablefish responded to the odour ofExpand

Stress‐induced impairment of predator evasion and non‐predator mortality in Pacific salmon
This study examined whether rapid recovery from stress-induced impairment in predator evasion, observed in previous studies on coho salmon, Oncorhynchus kisutch (Walbaum), was a generalExpand
