FishingRod is correct about perimeter and area. Also correct I think about what this would mean for minnow species. Especially for a minnow species like Blackstriped Topminnow or Gams. But other minnows should also benefit and probably also BG fry.
Sunil, think of a 1/4 acre as ~10,000 sq ft. If a square the perimeter is 400 ft. But if 1 ft wide it is 10,000 feet long with a perimeter of 20,002 ft. So the skinny example is very extreme but the perimeters of otherwise equal areas are very much dependent on shape.
