Issue 4 2012


Without question, one of Fish Farming News’s most frequently reprinted and widely respected columnists is Rod Getchell, author of our long-running, popular feature, Fish Health Notes.

Dr. Rod’s columns are always timely, authoritative, and chock full of vital information essential to fish farmers everywhere.

His work is so solid that it was difficult to look back and pull a few selections from the archives for this “Best of Fish Health Notes” retrospective.

But these were some of our favorites (along with the issue dates in which they originally appeared). We hope you agree. —Editor
