Breakdown of the brown trout evolutionary history due to hybridization between native and cultivated fish
As previously discussed, fishing tends to exploit certain size and age classes in populations, leaving managers with the problem of maintaining healthy populations. Last week we discussed how somatic growth rate and population levels of harvest will evolve in directions … Continue reading
Sustaining Fisheries Yields Over Evolutionary Time Scales
Fisheries want to exploit the largest fish, usually enforcing minimum size limits, which creates a truncated size and age distributing that lack larger and older fish. This form of management tends to ignore the potential for evolutionary change in harvestable … Continue reading
