Invasive Crabs in a Random Forest—A Study of Prices for Crabs from the Barents Sea 1: Centre for Applied Research at NHH, Norway; 2: Beijer Insitute of Ecological Economics, Sweden Snow and red king crabs are established invasive species in the Barents Sea that support significant commercial fisheries. Invasive species have ecological impacts but represent opportunities for value creation as climate change may undermine more traditional fisheries. However, climate change could also have negative impacts on the crabs. Landing or ex-vessel prices exhibit large variations over short time spans, suggesting a non-standard or complicated market structure, and we consider regression trees in random forests to identfy important factors for prediction of these prices. The most important variables for snow crab prices are landing site and prices of other landings the same day. We find little evidence of impact on snow crab prices from landed volumes and prices of red king crab, suggesting limited substitution in the market. An index of marine heatwaves, a phenomenon correlated with climate change, is the last variable on the ranking of importance for price determination. Transition to quota regulation, however, shifted the price up with 17% on average. | |
