I use that technique for pretty much every fish I clean, and have for 20 plus years. The only time I break out the electric filet knife is if I'm cleaning 30 or more...the electric knife is a time saver but you also lose some meat in the process, especially on the smaller fish.

Catfish is similar with the exception of starting...I actually start catfish sitting up with the dorsal spine pointing upwards. Otherwise very similar.
