Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska

Fisheries Oceanography, EarlyView.
ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

Fisheries Oceanography, EarlyView.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

(Not) Covering Climate Risks: A Multimodal News Framing Analysis of Soil Health Reporting in the UK Press

The Geographical Journal, EarlyView.
Short Abstract Risks to soil health from increased flooding and drought due to climate change are a priority risk area for the UK government, but our analysis of two years of UK newspaper coverage on this issue reveals very little attention to it. Our multimodal framing analysis shows that news reports are largely devoid of addressing the root causes ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

Transcriptomic profiling of gill biopsies to define predictive markers for seawater survival in farmed Atlantic salmon

Journal of Fish Biology, EarlyView.
Abstract Wild Atlantic salmon migrate to sea following completion of a developmental process known as parr‐smolt transformation (PST), which establishes a seawater (SW) tolerant phenotype. Effective imitation of this aspect of anadromous life history is a crucial aspect of commercial salmon production, with current industry practice being marred by ...

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

Journal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.
