The Effect of Fishery Management on the Yield of the Critically Endangered European Eel Anguilla anguilla in Mesotrophic Rivers and Streams in Central Europe

open access: yesFishes, 2022
The European eel Anguilla anguilla is a critically endangered catadromous migratory fish species. To conserve eel populations, angling restrictions and stocking activities are often used.

Angler and environmental influences on walleye Sander vitreus and muskellunge Esox masquinongy angler catch in Escanaba Lake, Wisconsin 2003-2015.

open access: yesPLoS ONE, 2021
Angler trip success and catch rates are dependent upon a fishes' vulnerability to angling. Angling vulnerability can be influenced by angler-specific attributes (i.e., bait choice, lure size, use of a guide), and individual fish traits (i.e., boldness ...

Multispecies fish tracking across newly created shallow and deep habitats in a forward-restored lake

open access: yesMovement Ecology, 2023
Background Freshwater fish communities typically thrive in heterogenous ecosystems that offer various abiotic conditions. However, human impact increasingly leads to loss of this natural heterogeneity and its associated rich fish communities.

Instantons at angles [PDF]

open access: yesPhysics Letters B, 1998
We interpret a class of 4k-dimensional instanton solutions found by Ward, Corrigan, Goddard and Kent as four-dimensional instantons at angles. The superposition of each pair of four-dimensional instantons is associated with four angles which depend on some of the ADHM parameters.

Angling gear avoidance learning in juvenile red sea bream: evidence from individual-based experiments

open access: yesJournal of Experimental Biology, 2021
Angling gear avoidance learning is a possible factor that contributes to the vulnerability of caught-and-released fish to angling. Whereas past studies suggested angling gear avoidance learning, they were based on large-scale experiments on groups of ...

Fused Angles and the Deficiencies of Euler Angles [PDF]

open access: yes2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018
Just like the well-established Euler angles representation, fused angles are a convenient parameterisation for rotations in three-dimensional Euclidean space. They were developed in the context of balancing bodies, most specifically walking bipedal robots, but have since found wider application due to their useful properties.

Potential Factors Limiting Brown Trout Catches by Anglers - A Case Study

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2021
In recent years, the numbers of native brown trout caught by anglers has declined throughout the Czech Republic. In this study, we focus on individual factors potentially related to this negative trend, based primarily on long-term angling catch data ...
