Saskatchewan has increased fines for illegal hunting and fishing.

Environment Minister Ken Cheveldayoff says penalties have more than doubled for serious infractions.

For instance, unlawfully hunting from a vehicle is now punished by a $1,000 fine -- up from $500.

The fine for fishing during closed times has doubled to $400, plus $50 a fish to a maximum of $2,000.

Cheveldayoff says the province wanted to set a strong deterrent to those who abuse its natural resources.

The changes result from a survey of anglers and hunters in 2012 and from a recommendation by a government committee.
