Transference  and Warframe abilities cannot be cast while wielding a Fishing Spear and will remain so until the player switches to a weapon.

Actually, if you have a key to cast selected ability, you can cast with it.

Myself, I either use 1 to 5 for them or select and cast with mouse wheel, using mouse wheel lets me use my abilities.
