Assessing the performance of statistical classifiers to discriminate fish stocks using Fourier analysis of otolith shape
(Peer reviewed; Journal article, 2020)The assignment of individual fish to its stock of origin is important for reliable stock assessment and fisheries management. Otolith shape is commonly used as the marker of distinct stocks in discrimination studies. Our ... -
Bioeconomic consequences of fishing-induced evolution: a model predicts limited impact on net present value
(Peer reviewed; Journal article, 2015-04)Fishing reduces stock size and shifts demographics, and selective mortality may also lead to evolutionary changes. Previous studies suggest that traits may change evolutionarily because of fishing on decadal time scales. ... -
Catch-and-release of Atlantic cod (Gadus morhua): post-release behaviour of acoustically pretagged fish in a natural marine environment
(Peer reviewed; Journal article, 2014-10-07)Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, ... -
Density-dependent consequences of size-selective induced life-history changes to population fitness in medaka (Oryzias latipes)
(Journal article; Peer reviewed, 2020)There is an increasing concern about the potential for size-selective harvest to impair population persistence. Yet little is known about the relative contribution of the evolutionary (shifts in life history) and demographic ... -
Environmental drivers of herring growth and how the perception shifts with time series length
(Journal article; Peer reviewed, 2022)Growth is a key component of population dynamics and, thus, fisheries management, yet drivers of its variations are often poorly understood. Using individual data collected over 80 years, we explored how environmental ... -
Temperature exposure in cod driven by changes in abundance
(Journal article; Peer reviewed, 2022)Animals actively select the most suitable habitat in terms of fitness, much of which is mediated by temperature. We reconstructed population abundance, oxygen isotope and temperature chronologies for the Icelandic and the ... -
Trade-offs between growth and reproduction in wild Atlantic cod
(Peer reviewed; Journal article, 2014-04-08)Animals partition and trade off their resources between competing needs such as growth, maintenance, and reproduction. Over a lifetime, allocation strategies should result in distinct trajectories for growth, survival, and ...
