Spawning, Hot Weather and When Not to Fish
Knowing when to stop fishing is part of responsible angling. Carp can be particularly vulnerable during spawning, extreme temperatures and oxygen stress.

Spawning activity
Carp may gather in shallow areas, thrash among vegetation and become highly focused on reproduction. Many fisheries close during spawning; give fish space and follow staff guidance.
Hot weather and low oxygen
Very warm water can reduce dissolved oxygen and make fish less resilient during long fights. Watch for fish gasping at the surface, distressed fish or emergency fishery notices.
Cold-weather handling
Cold conditions can also affect fish and anglers. Keep fish handling efficient, and do not take unsafe risks around icy or slippery banks.
Respect temporary closures
A fishery may prohibit fishing, retention or baiting at short notice for stock welfare. Follow these decisions even if you see fish visibly feeding.
Questions
Do all lakes close during spawning?
No. Rules vary, but disturbance should still be minimised.
Are feeding fish always fit to be caught?
No. Environmental conditions can make catching and handling harmful.
