I find it to be a bit excessive and odd that it requires angler fish, an odd choice just in general. It does not seem like a very edible fish.

I ended up catching about 15 of them by hand, it's extremely easy to just push them up onto the shore and grab. No need for fishing.

Bizarre design choice. I guess it makes them rare and coveted to have but not by much. You can easily bypass never making fish and bread and use omelets or salads. But it's nice to have for bosses or whatever, tho I don't see the extra 5 points being very relevant.

One thing I've noted is that angler fish do not seem to be respawning in the same places once I've fished the area out. Making stockpiling this food item excessively difficult with little rewards in doing so beyond just being a collector.
