Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

Accounting for the Evolution of China's Production and Trade Patterns

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study the evolution of China's production and trade patterns during its integration into the global economy. Using firm‐level microdata, we document how production and exports shifted across industries and within industries across firms.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...
