When captured on hook and line in deep water and brought rapidly a f i r s t l o o k at re a l i s m 35 to the surface, the fish can die. The gas in the swimbladder obeys the laws of physics and expands as it encounters the lower water pressure near the surface. Unfortunately, these fish are not able to release the rapidly expanding gas very quickly.

Manually dumping a bucket of water into the tank produced the right e¤ect, but I couldn’t keep doing that all day long. I needed an automatic bucket dumper.

When the bucket was empty it hung there upright in normal bucket fashion, but when it was filled with water it became topheavy and flipped over, dumping the water.
