These fish are born female and later become male; heavy fishing may be changing them at the molecular level

• Pearly razorfish begin life as females before some naturally transition into males.- National Geographic photoFishing is known to reduce fish populations and change the size and age of fish found in the wild.
• But a new study suggests that the effects may go much beyond.
• Researchers have found that heavy fishing may be changing the biology of the pearly razorfish at the molecular level.
