Fishes in general, both in salt and fresh waters, are observed to sport most and bite more eagerly against rain than at any other time.
Black-fish.
Black-fish in schools indicate an approaching gale.
Blue-fish, pike, etc.
Blue-fish, pike, and other fish jump with head towards the point where a storm is frowning.
The approach of blue-fish to the Middle Atlantic coast is a true indication of a shift of wind to the north within twenty-four or thirty-six hours. The observer furnishing the above states that he has not known this saying to have failed once in the past twenty-five years, and assigns as a reason that in autumn all fish go south, and the blue-fish, it appears, is able to anticipate this change and approaches the coast, where it may strike the feed-fish on their way south.
Clam-Beds.
Air-bubbles over the clam-beds indicate rain.
Porpoises in harbor indicate coming storm.
Cat-fish.
