A comparative analysis of aggression in migratory and non-migratory salmonids
TLDR
Aggressiveness was significantly and positively correlated with the duration of stream residence, and non-anadromous Salvelinus fontinalis showed the highest levels of aggressive behaviour.
Atypical correlation of otolith strontium : calcium and barium : calcium across a marine–freshwater life history transition of a diadromous fish
TLDR
The results demonstrate that Ca variation in freshwaters can potentially be an important influence on otolith element : Ca ratios and that inferences of marine–freshwater habitat use from otolith Sr : Ca alone can be problematic without an understanding of water chemistry.
A compendium of ecological knowledge for restoration of freshwater fishes in Australia
Many freshwater fishes are imperilled globally, and there is a need for easily accessible, contemporary ecological knowledge to guide management. This compendium contains knowledge collated from over
VI. DECREASED AGGRESSIVE BEHAVIOR IN MASU SALMON (ONCORHYNCHUS MASOU) DURING THE PARR-SMOLT TRANSFORMATION
TLDR
Examining changes in aggressive behavior during the parr-smolt transformation of masu salmon and comparing frequency of nipping behavior to changes in concentration of plasma thyroxine finds that reduced aggression is an important behavioral change in preparation for downstream migration by masu Salmon, and also for other salmonid species.
Effects of Tag Location on Detection Rates of Visible Implanted Elastomer (VIE) Tags in Juvenile Silver Perch, Bidyanus Bidyanus (Mitchell) and Australian Bass, Macquarie Novemaculeata (Steindachner)
This aper examines the effect of tag location and time upon visibility rates of Visible Implanted Elastomer (VIE) tags implanted in juvenile silver perch, Bidyanus Bidyanus and Australian bass,
The invasion of a south-western Australian river system by Perca fluviatilis: history and probable causes
A survey conducted among freshwater anglers indicated that during the 1980s Percafluviatilis L. rapidly invaded the middle and lower reaches of the Murray River, Western Australia. This exotic
