From The Cutting Edge (Pond Boss Mag) -- Using Radiotelemetry to Compare the Initial Behavior and Mortality of Hatchery-Reared and Wild Juvenile Florida Bass, by Brandon C. Thompson, Wesley F. Porak, Erin H. Leone & Micheal S. Allen in Transactions of the American Fisheries Society, 145:2, 374-385, DOI: 10.1080/00028487.2015.1131739 (2016).
The maximum distance traveled by a hatchery fish was 3.03 kilometers in a 24 hour period, which included swimming the distance of the lake into an adjoining lake. It was confirmed that this was a live hatchery bass (and not a tag being carried off by a predator) by capturing it with an electrofishing boat.
Eric, I am reminded of when I would run an additional 6 miles after track practice. Sometimes I would do it on the track which means I was never much more than 200 yards from any place or any time while on the track. But sometimes I hit the road and could be several miles separated at different times. The point is ... I was pretty much running at the same pace whether I was running the oval track or on the road. My speed and total movement were comparable. I think LMB make more distance than we give them credit for when they are not on the road. To move 1 mile in 5 hours requires constant movement of only 3.5 inches per second (17 feet per minute). When I fish, I see LMB moving in and out a lot but more infrequently see them resting. I think its possible that most LMB 12" to 18" could move more than a mile a day.
Is this a possible argument for MORE COVER in a LMB pond?
If the predators move more than we expect, then perhaps the forage fish also move more than we expect?
If a LMB can loaf in a good ambush spot, and the forage swims past that spot, then the bass gets a meal for very little energy expended. If the LMB has to roam the pond AND find unaware forage fish, then wouldn't the bass have to expend more energy roaming for food, plus more energy for an expected lower success rate for capturing forage during an "attack"?
