Barbel are powerful freshwater fish found in fast-flowing rivers. Their welfare in angling is complicated by their extreme vulnerability to warm water conditions during the summer months.
Barbel welfare in angling is uniquely challenging because these fish fight extremely hard for their size, depleting energy reserves to dangerous levels. In warm water above 18 degrees Celsius, their recovery is severely impaired. Fish that appear to swim away after release may die hours later from delayed exhaustion. Long-term retention in recovery slings improves survival. The Barbel Society has developed detailed warm-weather protocols including mandatory recovery time and temperature-based self-imposed fishing bans that represent best practice in freshwater welfare advocacy.
