1.
The Part of the Year when it is both Legally, and Ecologically, Acceptable to Hunt for Animals,Fish or Game, of a Particular Species.
All the (civilised) Local National Governments set Start and End Dates for the Open Season; and the Closed Season.
These dates can be different for each of the Animals, Fish, or Game Species which a Hunter/Angler wants to target.
In Order to Avoid Being Caught, Arrested and Fined, it is necessary to Find out what the Start and End Dates are for the Open Season; as it applies to the Species of Quarry which YOU want to Hunt.
( The Survival of Species is At Stake; So Don't Risk Being Busted.)
The Fines are, Quite Rightly; VERY PAINFULLY EXPENSIVE.
