Maturation characteristics in Norwegian spring-spawning herring before, during, and after a major population collapse
Engelhard, Georg H.; Heino, Mikko (ICES CM documents, Working paper, 2002)The immense Norwegian spring-spawning herring (Clupea harengus) population collapsed to the state of commercial extinction in the late 1960s, probably largely due to overfishing; the stock has fully recovered since the ... -
Northeast Atlantic blue whiting
Heino, Mikko (ICES Cooperative Research Report;306, Working paper, 2010-10) -
On the interplay of environmental changes and fishing pressure in exploited fish stocks
Boukal, David S.; de Roos, Andre M.; Persson, Lennart; Heino, Mikko (ICES CM documents;2010/M:15, Working paper, 2010)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. At the same ... -
The Propensity of Marine Reserves to Slow the Evolutionary Effects of Fishing
Dunlop, Erin S.; Baskett, Marissa L.; Heino, Mikko; Dieckmann, Ulf (ICES CM documents, Working paper, 2006) -
Reaction norm analysis of fisheries-induced adaptive change and the case of the Northeast Arctic cod
Heino, Mikko; Dieckmann, Ulf; Godø, Olav Rune (ICES CM documents, Working paper, 2002)We present a probabilistic concept of reaction norms for age and size at maturation, and outline methods that can be used for their estimation in typical fisheries data. Such estimations are critical for calibrating size- ... -
Reaction norms for age and size at maturation: study of the long-term trend (1970-1998) for Georges Bank and Gulf of Maine Atlantic cod stocks
Barot, S.; Heino, Mikko; O’Brien, Loretta; Dieckmann, Ulf (ICES CM documents, Working paper, 2002)Average age and size at maturation have decreased in many commercially exploited fish stocks during the last few decades. This phenomenon could be either a direct phenotypic response to some environmental variation, or the ... -
Report of the Planning Group on Surveys on Pelagic Fish in the Norwegian Sea [Bergen, Norway, 28- 30 August, 2002]
Jacobsen, Jan Arge; Gudmundsdottir, Asta; Heino, Mikko; Holst, Jens Christian; Krysov, Alexander; Melle, Webjørn; Mork, Kjell Arne; Røttingen, Ingolf; Tangen, Øyvind; Vilhjálmsson, Hjálmar (ICES CM Documents;2002/D:7, Working paper, 2002) -
Scientists as facilitators: An objective technique to illustrate a zone of stakeholder consensus
Dankel, Dorothy Jane; Heino, Mikko; Dieckmann, Ulf (ICES CM documents;2009/ O:28, Working paper, 2009)The inherent conflicts between objectives in fisheries management (e.g. yield max-imization vs. conservation interests) often create problems for managers, scientists and stake-holders. However, some seemingly contrasting ... -
Size structure, age-size dynamics and life history variation
Heino, Mikko; Boukal, David S.; Falkenhaug, Tone; Piatkowski, Uwe; Porteiro, Filipe M.; Sutton, Tracey T. (ICES CM documents;2008/F:13, Working paper, 2008)Here we present a new technique to study life history variation when only length distributions of populations are known. Shape of length distribution in a population is to a significant extent determined by the degree ... -
Success in fishery management by reconciling stakeholder objectives in Hilborn’s “zone of new consensus”
Dankel, Dorothy Jane; Dieckmann, Ulf; Heino, Mikko (ICES CM documents;2007/O:17, Working paper, 2007)The inherent conflicts between objectives in fisheries management (e.g. MSY vs. conservation interests) are a hurdle for managers and scientists. However, some objectives may be compatible (e.g. economic yield and ecosystem ... -
The bioeconomic consequences of fisheries ]induced adaptive changes
Zimmermann, Fabian; Jørgensen, Christian; Steinshamn, Stein Ivar; Heino, Mikko (ICES CM documents;2010/M:02, Working paper, 2010) -
Variations in the distribution of blue whiting in the Barents Sea: climatic influences or year class effects?
Heino, Mikko; Engelhard, Georg H.; Godø, Olav Rune (ICES CM documents, Working paper, 2003)Blue whiting (Micromesistius poutassou) in the Barents Sea represent the north-eastern fringe of the distribution of the species in the Atlantic. Distribution and abundance of blue whiting in the Barents Sea have fluctuated ...
