What is environmental stochasticity and how does it lead to population decline?
Answer later
Problems applying MSY
Very difficult to get accurate estimates of population size.
Carrying capacity changes - impossible to estimates.
Basic demographic data rare, vary between populations.
Difficult to get measures of other forms of mortality.
Social systems and mating strategies - often unknown.
Pays to over-harvest long lived species, drive extinction.
