Researchers use light traps to illuminate Dungeness crab decline

A recent crash in population prompted a multi-partnership study to analyze crab abundance patterns in the Pacific Northwest.

SEATTLE — Researchers are waging a quiet battle in the Pacific Northwest to protect one of the region’s most iconic species — the Dungeness crab.

Using light traps, scientists at the MaST Center Aquarium in Des Moines are gathering data that could help safeguard the future of Washington’s most valuable wild-caught fishery.

The study aims to fill in gaps in the biological data on Dungeness crabs. Researchers hope that by monitoring the early stages of their development, they can better predict crab populations and avert crises
