Location: Denmark | We know that some fish experience changes to their hemostatic parameters due to being caught in deeper waters. But I have often experienced Pike rising from 1 to 4 Meters in the water column to strike or follow a bait at boatside.
So does anyone know the biological limits of these fish, and their ability to quickly change depth in connection with, striking a lure etc.

| I don't think there's any scientific data to show the biological limitations of their ability to quickly change depth. They're physostomous fish which means their swim bladder has a direct connection to the outside world allowing them to gulp air for added buoyancy or burp air to submerge. The quick and dirty answer to your question is "who knows," but it is theoretical that there are perhaps no limitations given the phyostomous nature of the fish. (Physoclistous fish such as perch, bass, and walleye may not be able to burst from depth to snatch a lure just beneath or at the surface).
Here's a book you can check out on Google: "Where the Fish Are" (search within it for physostomous or physoclistous) |

| here's another question, how do they gulp or burp air during the winter months? they must just have to deal with it or something! |
