Stress-associated impacts of short-term holding on fishes
Stress associated with short-term holding of fishes can have negative effects on overall health and well-being, and an understanding of the stressors affecting fish holding can lead to practices that reduce stress and its detrimental effects. Expand
Effects of global climate change on marine and estuarine fishes and fisheries
There is a need to research the physiology and ecology of marine and estuarine fishes, particularly in the tropics where comparatively little research has been conducted, to make more accurate predictions and forge relevant solutions. Expand
Environmental tolerances and requirements of splittail
Abstract The range of splittail Pogonichthys macrolepidotus has decreased to less than a third of its original range due to loss or alteration of habitats. We measured the critical thermal minimaExpand
Hydropower-related pulsed-flow impacts on stream fishes: a brief review, conceptual model, knowledge gaps, and research needs
There is a clear need for a quantitative framework incorporating mathematical representations of field and laboratory results on flow, temperature, habitat structure, fish life stages by season, fish population dynamics, and multiple fish species that can be used to predict outcomes and design mitigation strategies in other regulated streams experiencing pulsed flows.

Tidal Influence on Spatial Dynamics of Leopard Sharks, Triakis semifasciata, in Tomales Bay, California
Leopard sharks showed strong movement direction patterns with tide, and moved significantly towards the inner bay, apparently to exploit the extensive inner bay muddy littoral zones' food resources. Expand
Effect of Temperature on Oxygen Consumption of the Leopard Shark, Triakis Semifasciata
The leopard shark, Triakis semifasciata, regularly resides in California's Tomales Bay, which is characterized by thermally different regions ranging from 10°C to 26°C during the summer. Past studiesExpand
Artificial Spawning and Larval Rearing of Klamath River Green Sturgeon
Two female and five male prespawning green sturgeon Acipenser medirostris that were caught and held in cages in the Klamath River, California, were induced to spawn by injections of gonadotropin releasing hormone analog (GnRHa) and domperidone and sampled for age, body size, sperm motility, hatchery fecundity, and oocyte diameter.

Effects of short-term management stress and ACTH injections on plasma cortisol levels in cultured white sturgeon, Acipenser transmontanus
Resting levels of cortisol and the cortisol responses to two management stressors and to exogenous adrenocorticotropic hormone (ACTH 1–24 ) injections in cannulated mature male white sturgeon were determined. Expand
Salinity-dependent changes in Na+/K+-ATPase content of mitochondria-rich cells contribute to differences in thermal tolerance of Mozambique tilapia
It is concluded on the basis of the different responses to temperature acclimation that salinity-induced changes in the NKA concentration of MRCs alter thermal tolerance limits of tilapia. Expand
Improved Growth, Swimming Performance, and Muscular Development in Exercise-Conditioned Young-of-the-Year Striped Bass (Morone saxatilis)
It is suggested that exercise-conditioned striped bass used for stocking purposes might show increased survival rates in the wild, although white muscle areas of exercised wild fish were significantly greater than in the unexercised cultured fish. Expand
