For Salmon no way, but maybe for the piles of sea bass- might come in handy... Why you gutting the salmon before filleting? Unless your doing it early to keep them cold??
I would challenge anyone to a race, I'll use a knife you use an electric. Sea bass or salmon, I'll bet I can beat an electric. I tried them for a while after seeing a guy use one but once you learn how to use a knife (and how to keep it sharp) there is nothing better. I'll be in Westport next weekend if anyone's up for the challenge.
For larger walleye, rock fish or ling cod, getting through the ribs with an electric would be an advantage. For small pan fish, I can run one of those cheap red handled fillet knife like no tomorrow!
