Accumulated marine pollution and fishery dynamics
Bergland, Harald; Pedersen, Pål Andreas; Wyller, John Andreas (Peer reviewed; Journal article, 2019) -
Aquaculture, pollution and fishery - dynamics of marine industrial interactions
Bergland, Harald; Burlakov, Evgenii; Pedersen, Pål Andreas; Wyller, John Andreas (Peer reviewed; Journal article, 2020)We model bioeconomic interrelations between a commercial fishery and an aquaculture industry by using a dynamical systems theory approach. The biomass follows a logistic growth where the pollution emerging from aquaculture ... -
Stable and unstable equilibrium states in a fishery-aquaculture model
Bergland, Harald; Pedersen, Pål Andreas; Wyller, John Andreas (Peer reviewed; Journal article, 2018)We study interactions between fishery and aquaculture using a 3D generalized Lotka - Volterra model, where we assume that the aquaculture production may affect the growth rate in the fish stock and the productivity in harvesting. ... -
Time Delays and Pollution in an Open Access Fishery
Bergland, Harald; Mishra, Purnedu; Pedersen, Pål Andreas; Ponossov, Arkadi; Wyller, John Andreas (Peer reviewed; Journal article, 2022)We analyze the impacts of pollution on fishery sectorusing a dynamical system approach. The proposedmodel presupposes that the economic developmentcauses emissions that either remediate or accumulatein the oceans. The model ...
