Yes having a rod and reel can be great but most freshwater fish can be caught on a cane pole.
As far a BOB's and PSK's that is a matter of personal preference.
I tend to go a lot lighter than a lot of other ETS members; so in most cases all I might have is a few hooks and line.
For short time survival food is not an issue.
Longer term scenarios would involve getting food anyway possible. Trot lines in the water and traps / snares on land.
While actively hunting and pole fishing too.
