"Fishery doctors at the present day remind me of human doctors in 

 my youth — they were always for doing something. I remember one 

 of my teachers laid down the notable maxim, 'When you are in 

 doubt, play a trump,' and I should think that those of us who have 

 followed his advice in the last forty years must have largely added to 

 the bills of mortality. Our fishery doctors are of the same mind as 

 my friend. They are (or at any rate they ought to be) very much in 

 doubt, and yet they continually want to play trumps in the shape of 

 stringent regulations and restrictions. If I might tender a piece 

 of advice, I would say — don't." — Huxley, "Fish Diseases," Inter- 

 national Fisheries Exhibition Literature, London, 1883.
