Inter‐annual changes in winter conditions elicit changes in fish behavior under lake ice

Ecology, Volume 107, Issue 10, October 2026.
Abstract Winters are warming faster than other seasons, and ice cover duration on temperate lakes is shortening. How ectotherms respond to these changes during poorly studied winter periods remains unclear. Here, we use acoustic telemetry to determine whether the same individuals of a model warm‐adapted fish, smallmouth bass (Micropterus dolomieu ...

Activity and metabolic rate of free-swimming smallmouth bass (Micropterus dolomieu) in large, interconnected ecosystems

Animal Biotelemetry
Background In large, interconnected systems such as the Laurentian Great Lakes, little is known about how smallmouth bass (Micropterus dolomieu) activity varies across contrasting habitat types.

The Effect of Temperature, Flow, Density and Disease on Smallmouth Bass (Micropterus dolomieu) Early Life Growth Rate

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Individual growth rates of fish are influenced by gradually changing environmental conditions and rapid‐onset events. However, there is a paucity of information on drivers of spatiotemporal variability in growth rates of fishes across large spatial extents.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

Fisheries Management and Ecology, Volume 33, Issue 5, Page 949-962, October 2026.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Ultrasonographic sex identification of Largemouth Bass and Smallmouth Bass

North American Journal of Fisheries Management
ABSTRACT Objective Intersexual variation within fish species can be observed through morphological, physiological, and behavioral differences. Although this variation can have important implications for the ecology and management of many fish species, challenges associated with the methods to ...

Microhabitat Use by Smallmouth Bass in an Ozark Stream

Journal of Freshwater Ecology, 2007
ABSTRACT Microhabitat use by smallmouth bass (Micropterus dolomieu) versus availability was evaluated in Baron Fork Creek, Oklahoma, an Ozark stream, using resource selection function analysis. Use of water depth and velocity, substrate size, and cover was measured at fish locations marked during underwater observation, and habitat availability was ...

Identification and Characterization of Germ Cell Genes Vasa and Nanos-2 in the Ovary and Testis of White Crappie (Pomoxis annularis) and the Ovary of Black Crappie (P. nigromaculatus)

Fishes
The vasa gene, encoding an ATP-dependent RNA helicase, and the nanos-2 gene, an RNA-binding protein, are essential for germ cell origination, migration, maintenance, and development in vertebrates and invertebrates.

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

Journal of Fish Biology, Volume 109, Issue 4, Page 2130-2146, October 2026.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

Heat exchange rates between adult sockeye salmon (Oncorhynchus nerka) and the environment

Journal of Fish Biology, Volume 109, Issue 3, Page 1810-1823, September 2026.
Abstract Body temperatures of salmon do not always match the temperatures of their immediate environment. We investigated the relationship between varying ambient water temperatures and body temperatures of adult sockeye salmon Oncorhynchus nerka using Newton's law of cooling and non‐linear mixed models.

Long-term fish community response to a reach-scale stream restoration

Ecology and Society, 2016
At a global scale, aquatic ecosystems are being altered by human activities at a greater rate than at any other time in history. In recent years, grassroots efforts have generated interest in the restoration of degraded or destroyed aquatic habitats ...
