Filamentous algae

Filamentous algae are single algae cells that form long visible chains, threads, or filaments. These filaments intertwine forming a mat that resembles wet wool. Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants). Often filamentous algae floats to the surface forming large mats, which are commonly referred to as Pond scums. There are many species of filamentous algae and often more than one species will be present at the same time in the pond. -Source

 

Is a small, thread-like species that is much more efficient at nutrient uptake than mature colonies? -Source

 

Type of algae characterized by long chains of attached cells that give it a stringy feel and appearance.

 

Controlling Filamentous Algae in Ponds - Its presence can degrade water quality and recreational enjoyment. Excessive algae can cause an oxygen depletion leading to a fish kill when it decomposes as a result of natural die-off or herbicide application. Early and regular control measures will help reduce the problems associated with filamentous algae.

 

Filamentous Algae - Multiple methods of control are available for filamentous algae that generally fall into physical, biological, or chemical categories. Combining and using multiple management methods is recommended.

 

Controlling Filamentous Algae in Ponds - The most common aquatic weed problem in many ponds is filamentous algae. Its presence can degrade water quality and recreational enjoyment. Excessive algae can cause an oxygen depletion leading to a fish kill when it decomposes as a result of natural die-off or herbicide application. Early and regular control measures will help reduce the problems associated with filamentous algae.

 

Filamentous Algae - Filamentous (green) algae, often called “moss” or “pond scum,” are characterized by long, hair-like strands, or filaments, of attached cells (often reaching two metres in length). Filamentous green algae respond to dissolved nutrients, especially nitrogen, with increased growth and reproduction.
