Speaking at the latest Institute of Fisheries Management (IFM) conference Leela explored the role of microorganisms in the natural environment, referencing our own
minnow pond case study. The same microbes that form the basis of the food web and used to grow our fisheries can also make significant water quality contributions, not only removing excess nutrients but using organic carbon that can be released during forestry operations.
Creating good fisheries habitat whether this is achieved by natural river restoration, the inclusion of gravel and brush structures or through the provision of a BioHaven floating island all help to start a new food chain as microbe based periphyton is formed on the surface of these structures.
Leela speaking at IFM
Nutrients, specifically phosphorus, taken up by the periphyton are eaten by increasingly larger animals transitioning the phosphorus in the form of protein up the trophic levels. The idea of providing this enhanced habitat to grow fish for harvesting as a useful product, closes the loop on nutrient cycling and creates a product that may be used for dog food or fertiliser.
However, it does not always need to be taken to extremes. Improving our river and lake morphology will improve water quality and support a more sustainable fishery. This is great for recreation and encouraging the next generation of anglers and conservation minded individuals to continue to support the important work to save our waters.
Providing fish with a good habitat will help our water to recover and support the rest of our ecosystem. You can all take part in transitioning our water back into good health.
