Panama Canal's Expansion Opened Routes for Fish to Relocate
Briefly

The expansion of the Panama Canal in 2016 allowed supersize ships, leading to a rapid shift in marine life as species from the Atlantic and Pacific began to migrate.
Fishermen around Lake Gatun, affected by the invasion of Atlantic species, report a scarcity of traditional catches like peacock bass and tilapia, raising concerns.
Researchers are increasingly worried about potential invaders like the lionfish, which, if they enter the eastern Pacific through the canal, could disrupt local ecosystems.
For millions of years, the isthmus of Panama has separated the Atlantic and Pacific Oceans, but the canal's expansion is creating new ecological challenges.
