A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery

Eikeset, Anne Marie; Richter, Andries Peter; Dankel, Dorothy; Dunlop, Erin; Heino, Mikko; Dieckmann, Ulf; Stenseth, Nils Christian (Journal article; Peer reviewed, 2012-12-12)

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 ...

Assessing changes in age and size at maturation in collapsing populations of Atlantic cod (Gadus morhua)

Olsen, Esben Moland; Lilly, George R.; Heino, Mikko; Morgan, M. Joanne; Brattey, John; Dieckmann, Ulf (Journal article; Peer reviewed, 2005)

By estimating probabilistic reaction norms for age and size at maturation, we show that maturation schedules of Atlantic cod (Gadus morhua) off Labrador and Newfoundland shifted toward earlier ages and smaller sizes ...

Body condition and evolution of maturation of Atlantic cod in Newfoundland

Baulier, Loïc; Heino, Mikko; Lilly, George R.; Dieckmann, Ulf (ICES CM documents, Working paper, 2006)

Atlantic cod (Gadus morhua, L.) stocks off Newfoundland and Labrador underwent severe depletions that started in the late 1980s and led to moratoria in the early 1990s. Fisheries closures are still applied in most of the ...

Can integrated assessments reconcile stakeholder conflicts in marine fisheries management?

Dankel, Dorothy Jane; Heino, Mikko; Dieckmann, Ulf (Conference object, 2009)

Eco-genetic models: a new framework for understanding fisheries-induced evolution

Dieckmann, Ulf; Dunlop, Erin S.; Heino, Mikko (ICES CM documents, Working paper, 2006)

Ecological and Evolutionary Recovery of Exploited Fish Stocks

Enberg, Katja; Dunlop, Erin S.; Heino, Mikko; Dieckmann, Ulf (ICES CM documents, Working paper, 2006)

Economic repercussions of fisheries-induced evolution

Eikeset, Anne Maria; Richter, Andries; Dunlop, Erin S.; Dieckmann, Ulf; Stenseth, Nils Christian (Journal article; Peer reviewed, 2013-07-23)

Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at a smaller size, which may have a genetic component and therefore long-lasting economic and biological effects. To date, the economic ...

Evolution of age and length at maturation of Alaskan salmon under size-selective harvest

Kendall, Neala W.; Dieckmann, Ulf; Heino, Mikko; Punt, André E.; Quinn, Thomas P. (Journal article; Peer reviewed, 2013-11-12)

Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation. Spawning ...

Evolution of reproduction periods in seasonal environments

Sun, Zepeng; Parvinen, Kalle; Heino, Mikko Petteri; Metz, Johan A.J.; de Roos, André M.; Dieckmann, Ulf (Peer reviewed; Journal article, 2020)

Many species are subject to seasonal cycles in resource availability, affecting the timing of their reproduction. Using a stage-structured consumer-resource model in which juvenile development and maturation are resource ...

An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.

Mollet, Fabian M.; Enberg, Katja Susanna; Boukal, David; Rijnsdorp, Adriaan D.; Dieckmann, Ulf (Peer reviewed; Journal article, 2023)

Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ...

Exploitation as a driving force of life history evolution: methods and empirical analyses

Heino, Mikko; Dieckmann, Ulf (ICES CM documents, Working paper, 2004)

Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that, under most circumstances, increased mortality at potential ages and sizes at maturation ...

Fisheries-Induced Changes in Age and Size at Maturation and Understanding the Potential for Selection-Induced Stock Collapse

Ernande, Bruno; Dieckmann, Ulf; Heino, Mikko (ICES CM documents, Working paper, 2002)

Fishing is very likely to create selective pressures inducing adaptive changes in the life histories of harvested stocks. Using field data and adequate statistical methods, such alterations can be demonstrated. However, ...
