Water temp up around 19 ( that's real good for down here ) just wanting to know how warm water has to be for tuna .

No idea. I usually cook mine in a little oil

Scroll down this page to the water temp data.

All the Comercial guys in Haast reckon anywhere above 21°C

Don't know what is going on here at the moment tuna wise.

We have had 2 weeks of fine weather and the sea in close is still dirty and has a roll.
Wasted a bit of fuel looking for a decent hole to do some surfcasting.

Might head to Jacksons later next week and chase a tuna and some blue nose.

albacore are often in 18deg water

Depends what kind of Tuna. Yellowfin and skippies like it warm. Albacore less so and Bluefin can handle quite cold water.

If my memory serves me the blues that hung around during Hoki spawn were in around 12-14deg.

Albies abt 16 for big ones. Warmer they get smaller. YFin 17-18. Warmer they get smaller. Bigeye similar but deeper water. Bluefin deep water 15-17. Different overseas with different spp.

Altho that may have been net monitor temp not surface come to think of it.

I was on a jap longliner off the west coast a while back. It was April/May and I recall catching Albacore then. Some bigs ones too. Definately worth a crack I'd say.

it's always worth trying

18 degrees of out of Greymouth, in 2014 we had to troll all the way to the fingers in the Hoki trench before getting any action, 2015 we hit them straight off Greymouth as soon as the water turned blue, 2016 no trip, 2017 all I have heard was that it took 3 days for 1.5 ton on a comercial boat. Nothing in the fishing paper up here about anyone getting any here this year.

2015 Greymouth




We got them on black and dark blue 6 inch rubber squid lures. Bleed them and into a ice slurry to chill them. They run very hot and spoil easily... my very limited experince / 2 cents worth.
