Mark-recapture estimation of mortality and migration rates for sea trout (Salmo trutta) in the northern Baltic sea
2016
Knowledge of current fishing mortality rates is an important prerequisite for formulating management plans for the recovery of threatened stocks. We present a method for estimating migration and fishing mortality rates for anadromous fishes that combines tag return data from commercial and recreational fisheries with expert opinion in a Bayesian framework. By integrating diverse sources of information and allowing for missing data, this approach may be particularly applicable in data-limited situations.Wild populations of anadromous sea trout (Salmo trutta) in the northern Baltic Sea have undergone severe declines, with the loss of many populations. The contribution of fisheries to this dec…

Fishing pressure impacts the abundance gradient of European lobsters across the borders of a newly established marine protected area
2019
Marine protected areas (MPAs) are considered viable fisheries management tools due to their potential benefits of adult spillover and recruitment subsidy to nearby fisheries. However, before–after control–impact studies that explore the biological and fishery effects of MPAs to surrounding fisheries are scarce. We present results from a fine-scale spatial gradient study conducted before and after the implementation of a 5 km 2 lobster MPA in southern Norway. A significant nonlinear response in lobster abundance, estimated as catch-per-unit-effort (CPUE) from experimental fishing, was detected within 2 years of protection. After 4 years, CPUE values inside the MPA had increased by a magnitu…
The social-ecological value of recreational fishing for sea trout; a potential for further development of the experience industry in Aust-Agder? (TRO…
2019
Prosjektleder Erik Höglund Prosjektet undersøkte hvilken betydning det å få sjøørret har for fritidsfiskere i form av fiskeglede og videre hva som er viktig for en god fiskeopplevelse. Bakgrunnen for dette er å få i stand et europeisk samarbeid og en søknad omkring sosio-økologiske problemstillinger i kystsonen, med fokus på fritidsfiske og turisme. I samarbeid med Aust-Agder Jeger- og Fiskeforening ble det utviklet mobil- og internettapplikasjoner som rapporteringsverktøy. Resultatene av bruken av dette verktøyet viste at fiskeeffektiviteten blant deltagerne var 1 sjøørret pr 5,34 timer fisket og det var ingen signifikant forskjell i fornøydhet knyttet til utstyrsvalg eller om fiskeren fik…
Responses of European lobster (Homarus gammarus) and lobster fishers to protective management
2017
Master's thesis Aquatic Ecology BIO500 - University of Agder 2017 Marine protected areas (MPAs) are valued for their conservation benefits to harvested species. However, potential benefits of MPAs to neighboring fisheries are less well-understood. This study quantifies how the European lobster (Homarus gammarus) and the fishery for this valued catch respond to the establishment of a relatively small (5.2 km2) MPA on the Norwegian Skagerrak coast. A series of yearly standardized trap surveys was conducted to estimate lobster abundance and catch weights both inside and outside the MPA before (2010- 2011) and after the MPA was established (2012-2016). Lobster abundance and catch weights were d…
Data from: Fishing pressure impacts the abundance gradient of European lobsters across the borders of a newly established marine protected area

Marine protected areas (MPAs) are considered as viable fisheries management tools due to their potential benefits of adult spillover and recruitment subsidy to nearby fisheries. However, before-after-control-impact (BACI) studies that explore the biological and fishery effects of MPAs to surrounding fisheries are scarce. We present results from a fine-scale spatial gradient study conducted before and after the implementation of a 5km2 lobster MPA in southern Norway.
