Assessing mackerel behaviour following crowding-induced stress in purse seine fisheries
(Master thesis, 2016-06-01)The practice of slipping in purse seine fisheries has been shown to cause high levels of delayed mortality in released fish. This unaccounted mortality could lead to bias in stock assessments, and brings the sustainability ... -
A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
(Peer reviewed; Journal article, 2013-05)Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ... -
Reaction norm analysis reveals rapid shifts toward delayed maturation in harvested Lake Erie yellow perch (Perca flavescens)
(Peer reviewed; Journal article, 2019-01-06)Harvested marine fish stocks often show a rapid and substantial decline in the age and size at maturation. Such changes can arise from multiple processes including fisheries‐induced evolution, phenotypic plasticity, and ... -
Summer distribution and demography of Antarctic krill Euphausia superba Dana, 1852 (Euphausiacea) at the South Orkney Islands, 2011–2015
(Peer reviewed; Journal article, 2018-11-22)We carried out a survey of Antarctic krill (Euphausia superbaDana, 1850) from 2011 to 2015 to establish a long-term, time-series dataset of distribution, abundance, and demography for this species in the South Orkney Islands ... -
What can selection experiments teach us about fisheries-induced evolution?
(Peer reviewed; Journal article, 2014-03)There is evidence that fisheries are altering the phenotypic composition of fish populations, often in ways that may reduce the value of fish stocks for the exploiters. Despite the increasing number of theoretical and field ...
