NOAA Grants Support Bycatch Reduction in Commercial Fisheries

In September 2014, NOAA Fisheries awarded 22 grants totaling more than $2.4 million as part of its Bycatch Reduction Engineering Program. Bycatch of various species-whether fish, marine mammals, or turtles-can have significant biological, economic, and social impacts. Preventing and reducing bycatch is a shared goal of fisheries managers, the fishing industry, and the environmental community.

Researchers awarded funding in 2013 are conducting research that has:

  • Developed timed-released chemical shark repellant that could reduce shark bycatch by 18-35 percent depending on the type and intensity of repellent used.
  • Reduced Chinook salmon bycatch in the Pacific hake fishery by using illumination to attract the salmon toward escape areas in midwater trawl nets.
  • Field-tested alternative deep-set buoy gear configurations that have been designed to selectively target swordfish at 250-350 meters during the day. Initial trials have confirmed that swordfish can be selectively targeted at depth, non-target catch (e.g., sharks) rates appear to be relatively low, and the gear has had no interactions with any endangered leatherback turtles.
  • Reduced widow rockfish bycatch by 26 percent by using a sorting grate that allows the smaller, target fish (Pacific hake) to pass through.

2014 Grant Recipients

The newly-awarded projects support bycatch reduction research around the country and address a variety of species, including flounders, Chinook salmon, red snapper, Jonah crabs, coastal sharks, skates, sea turtles, whales, and other marine mammals.
