BioHaven StreamBed to Grow Bigger Bass

We are always attempting to grow bigger bass! A few years ago, a doctoral student of eminent fish biologist, Dr Wes Neal, ran a study that measured fish growth in a pond that we’d fitted out with a BioHaven StreamBed.  This floating island blends surface area and circulation to speed up the growth of natural fish food, periphyton.  The study was done on ponds at the Mississippi State University campus.  

Their well-designed study found that the pond with islands grew 19% more fish biomass than the control pond.  Floating Island International has some nine thousand islands launched around the world now, including on some lakes and ponds associated with serious Pondmeisters.  In fact, I have two StreamBeds operating on Fish Fry Lake right here in Shepherd, Montana.  There’s a common denominator to all of these lakes and ponds that have floating islands…lots of fish.  

Fish Fry Lake really exemplifies this.  It’s an amazingly productive fishery.  Ten kids catch nearly 700 fish in four hours, as one example.  Best of all, the fish are super healthy and there’s a mix of age classes, with awesome bluegill, yellow perch, and bass to catch.  This is in part due to our slot-limit harvest approach, but the high volume fish biomass is key! 

At the time of the MSU study was published, the researcher suggested that the islands were an expensive way to grow bass.  Just the other day a pondmeister shared what he’s spent on chemicals to control algae and aquatic vegetation.  It approached island costs, and worst of all, the costs are not the one-time cost of an island, but just keep on happening!  

Floating Islands are a natural way to avoid using chemicals.  The thing about chemicals, too, is that they are scary.  You have to trust the labels!
Islands compete with algae and aquatic vegetation for nutrients, and nutrients are what grows the algae and aquatic vegetation you fight with chemicals.  Best of all, islands take those nutrients and cycle most of them into diatom based periphyton, which is a primary way to grow fish.
