Southland duck hunters may see fewer Mallard ducks this opening weekend, as Fish and Game's annual survey shows a drop in the game bird's numbers this season.

Southland Fish and Game field officer Bill Jarvie said Mallard numbers had come back, from the record highs of the last two seasons, to more of their long term average.

Jarvie said the survey was done last month (April) and primarily involved photos taken, from a helicopter, of randomly selected ponds and rivers all over Southland.

The biggest factor influencing numbers was the survival of juveniles, Jarvie said.

This was dependent on good weather conditions and the availability of shallow ' ephemeral' water, that comes and goes with rain events, which contains plenty of the invertebrates and protein that juvenile ducks must have.

Jarvie also said the enhancement and protection of stream habitats including those riparian strips provided nesting areas for the Mallard hen that needs that cover.

There currently looks to be settled weather conditions, Jarvie said, "so bring your barbecue".

He said Fish and Game officers would once again be out, assisted by Police, to see how everyone is getting on.

He said it was up to hunters to do the right thing, follow the regulations and be safe.

Police are also urging safety first.

They are reminding people that the seven safety rules have been updated, and to make sure hunters follow the new storage and transportation requirements for firearms and ammunition. 

Duck hunters are being urged to observe the 7 simple firearms safety rules:

1.      Treat every firearm as loaded

2.      Always point firearms in a safe direction

3.      Chamber a cartridge only when ready to fire

4.      Identify your target beyond all doubt

5.      Check your firing zone

6.      Store and transport firearms and ammunition safely

7.      Avoid alcohol or drugs when handling firearms
