This type of algae grows along the bottom of the pond in shallow areas and then floats to the surface to form bubbly looking mats that can sometimes cover entire ponds. Clear water is not good if pond owners desire a heathy fish population.įilamentous algae are made of single cells that form long visible chains, threads, and filaments that intertwine to resemble wet cotton or wool. Planktonic algae are the kinds of algae pond owners actually WANT and the fish NEED! It is important to manage and promote planktonic algae to build good fish populations because they provide food and oxygen for fish. Planktonic algae provide food for the microscopic animals (zooplankton) that are eaten by minnows, baitfish, and other pond inhabitants, which ultimately support a larger fish population. Planktonic algae are normal and are in fact desirable, because they are essential to the pond’s food chain. This type of algae is what gives the water a green coloration. Planktonic algae are the microscopic, single-celled, and free-floating algae that exist in the top few feet of a pond or lake where the sunlight penetrates. There are three different types of algae commonly found in farm ponds and small lakes: planktonic, filamentous, and macroalgae. The first step to effective algae management is to understand what type of algae resides in the pond. Algal overgrowth is one of the most common issues for pond owners. If there’s a thick mat of bubbly yellow-green substance floating on the surface of the pond, or the pond appears to be colored bright green, blue-green, or sometimes even red, then there may be an algae problem. When the weather warms up and folks begin to dig out their fishing poles to go drop a line in their favorite pond, I start getting calls about pond weeds.
