Aquatic Biology and Ecology »
Each species of fish has unique habitat requirements, and parameters such as water depth, bottom type and presence or absence of aquatic plants partially dictate the suitability of a waterbody to support fish populations. NSC uses scientific and consumer grade echosounders (e.g. BioSonics Habitat MX and Lowrance HDS), coupled to survey, mapping or consumer grade GPS (respectively), to map aquatic habitat at varying resolutions in waterbodies of all sizes. NSC has undertaken hundreds of acoustic surveys in a wide variety of environments including urban rivers, remote Arctic lakes, and the reservoirs and tailraces of generating stations. Survey resolution is determined based on the project's information needs, and results are used to describe baseline conditions, as inputs for predictive modelling, and to monitor change over time.
