tips on Deep line

[Lion Heart]

I know this question has been asked a million times, because I've done so many searches, yet I still cant get good results on Deep line fishing.
I've tried releasing the deep line at different points as to where the fish is on the sonar, midway across the screen, at the very right hand of the screen, greater spacing of buoys. i wait between 18 and 22 hours. I've tried all the tips i can find, but I'm not getting the results I'm averaging one fish per line, sometimes 2 but never 3.
what am i getting wrong?
am i baiting incorrectly? it is Mackerel for Tuna and Squid for sword fish, that is correct right?
what am I not getting, I just cant get my head around this.
I'm sorry for asking this common question but none of the advice I have read seems to work for me.

Thanks in Advance everyone

I thought it was herring for tuna?

Yes, sorry I got mixed up, Herring, not Mackerel

3's are hard to get until your habitat population hits high or better. Try deeplining in the scallop Habitats while your waiting for the Tuna and Swordfish Habitat grow to a high population.
There are 6 scallop Habitats and they start out with a decent amount of Tuna and swordfish. But once you fish out all the Tuna and swordfish in the scallops the population does not regenerate the way it will in an actual Tuna or swordfish habitat.
Look me up on youtube "Battlecrom gaming". My quick start guides go over deeplining in scallop habitats.
