ltlCLEO,

I firmly believe that Blackmouth/Chinook (pretty much all fish) are nocturnal feeders.
Two reasons... (1) bait generally will be found near the surface or shallower waters during the evening hours feeding on zooplanton. Salmon in turn, are less likely to fall to predation under darkness. They feel comfortable feeding shallower. (2) The 60% sand lance diet.. Sand lance will burrow at night to rest and avoid predation. Funny how Mr. Blackmouth know exactly where they are at...

In addition to the tides, it is a good idea to know the illumination of the moon (weather dependent-clear skies). Just my experience shows that more illumination means slower fishing. Vice vesra for overcast nights/days. Bait fish make one heck of a silhouette under clear skies...

Blackmouth are feeding machines- 24/7. The trick is finding them.
