I'm working on a study where a single professional trapper removes furbearers and corvids (who the trapper is changes annually). I would suspect that the composition of the harvest would be strongly influenced by the individual's trapping style, ie. how and where they choose to set their choice of traps, as none of this is regulated. However, others argue that the harvest is reflective of species abundance and community composition. I'm having difficulty finding sources for either argument that aren't fisheries-centric. Can anyone suggest any?
