Coarse fish in Scotland: a threat or a resource? [PDF]
This brief article summarizes the ecological role of non-salmonid fishes in Scottish fresh waters. Most government-sponsored research has focused on the ecologically valuable salmonids in this area, yet non-salmonid species are widely distributed in ...

Selective precipitation reaction: a novel diagnostic test for tissue pathology in Atlantic Salmon, Salmo salar, infected with Salmonid Alpha-Virus (SAV3) [PDF]
While investigating biomarkers for infection with salmonid alphavirus (SAV), the cause of pancreas disease (PD), a selective precipitation reaction (SPR) has been discovered in serum which could be an on-farm qualitative test and an in-laboratory ...

Sterility of Salmonid Roe and Practicality of Hatching Gnotobiotic Salmonid Fish [PDF]
The ventral surface of spawning salmonid fish was opened aseptically and the roe were removed aseptically. Roe obtained by using this technique were demonstrated to be sterile. Aseptic fertilization and incubation of eggs obtained in this manner resulted in the hatching of gnotobiotic salmonid fish.

ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Domestication and captive breeding can compromise the obstacle- and predator-avoidance capabilities of animals in the wild. Whereas previous studies only examined these effects in combination, here we examine them individually by comparing the abilities ...

The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
