Application of the “River Model” to estimate the impact of fishing on the amount of anchovy available to west coast penguin colonies

Download (842.13 kB)

A simple approach is used to estimate the extent to which the amount of anchovy recruits of the year which would otherwise have been available to penguin colonies off the West Coast has been reduced by historic levels of fishing. Results suggest that over the past decade the extent of this reduction has been a median of 5-6% and at most some 25%.
