Interesting thing with the Sturgeon species is jumping seams to be something they all do, wherever they live. I’m not going to attempt to guess as to why, maybe they are just having fun!
Few weeks ago, the gulf sturgeon in Florida were on the news for jumping. The river these fish were in is starting to see more use by recreational fisherman and boaters and the sturgeon are becoming a hazard. Image that… humans moving into a new area and complaining about the wildlife that have always been there. Anyway, these sturgeon were big, couple hundred pounds, and clearing the water by 5-6′. Jetskis were running into them.
Sturgeon in MN tend to surface more than jump. Shovelnose do it, as well as the Lake Sturgeon on the Rainy River and St Croix. During the Sturgeon Excursion this year, sturgeon were surfacing all over the place on 4 mile bay. I’ve honestly never seen that many surface before.
My experience says that a decent bite is usually found in conjunction with these surfacing and leaping sturgeon. Now if you can find 20lb channel cats breaching on the Red River, hold on tight!!
