High-tech fishing gear could help save critically endangered right whales
Many fish, marine mammals and seabirds that inhabit the world’s oceans are critically endangered, but few are as close to the brink as the North Atlantic right whale (Eubalaena glacialis)Only about 411 of these whales exist today, and at their current rate of decline, they could become extinct within our lifetimes.
From 1980 through about 2010, conservation efforts focused mainly on protecting whales from being struck by ships. Federal regulations helped reduce vessel collisions and supported a slight rebound in right whale numbers.
But at the same time, growing numbers of right whales died after becoming entangled in lobster and crab fishing gear. This may have happened because fishing ropes became stronger, and both whales and fishermen shifted their ranges so that areas of overlap increased. Entanglement has caused 80% of diagnosed mortalities since 2010, and the population has taken a significant downward turn. Read more...
