Up to 19 fish-eating North Pacific killer whales can be accidentally killed annually by Alaska fishing fleets or other human activity without triggering a federal effort to reduce this toll.

“Killer whales are an iconic species,” said Doug DeMaster, who served as director of the federal Alaska Fisheries Science Center from 2001 to 2018. “A reasonable interpretation of the current data is that the current bycatch levels could be adversely affecting a western stock of resident killer whales.
” to be established for the resident killer whales. If that number — now set at 19 — is exceeded, NOAA Fisheries would be expected to designate these stocks as strategic and could eventually put together a team of conservation, fishing industry, government and scientific representatives. Their task would be to come up with a plan to reduce the annual deaths.
One vessel skipper experimented this year with a kind of water kite that stretched out in front of part of nearly half the net’s opening, according to John Gauvin, fisheries science director for the Alaska Seafood Cooperative. Gauvin said that the kite did not appear to impede fishing but more study is needed to determine how effective it could be in keeping whales out of the net.
These findings “highlighted the need to revisit current stock designations,” which are a “critical component for evaluating the impacts of incidental bycatch” in fisheries, according to a 2013 Journal of Heredity article about the study by Parsons and nine other scientists.
