PPT-Bioassessment using Benthic Algae

By Ista Ayuh Paramita SSi MP Aquatic Resource Management Faculty of Fisheries and Marine Science University of Brawijaya 1 Perifiton Bioassessment 2 The way we learn something Definisi. Algae Algae have been used in animal and human diets since very early times Filamentous algae are usually considered as macrophytes since they often form floating masses that can be easily harvested although many c By Mark .
