Shortfin mako sharks

Sharks are vulnerable to overfishing because of their low reproductive rates and often low growth rates. Most pelagic sharks fall near the middle of the shark productivity scale, and there is concern that catching too many of them could lead to population depletion. In New Zealand waters, mako sharks are the second most commonly caught shark species (after blue sharks) on tuna longlines.

White sharks

Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?

Pelagic shark risk assessments

NIWA has developed a new method for spatially-explicit, quantitative, sustainability risk assessment of pelagic shark population.
