Analysis Of Cpue From The Norwegian Bottom Trawl Fleet

, 2000
No abstracts are to be cited without prior reference to the author.Commercial logbooks with catch and effort data have been collected and recorded by the Norwegian Direcorate of Fisheries since 1971. Annual age segregated CPUE indices are calculated with different methods for North-east Arctic cod, North-east Arctic haddock and North-east Arctic saithe.

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

River Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Analyses of CPUE from the four islands of the Tristan da Cunha group to examine effects of trip length and period of rest between trips on CPUE performance

, 2022
Cursory examination of CPUE data as well as anecdotal evidence from skippers and fishermen have suggested that two important mechanisms may be at play concerning the behavior of CPUE values over time. Firstly, it has been suggested that CPUE falls off fairly rapidly during a single fishing trip.
