Freshwater Day; Introduction to Surveying Streams for Migratory Fish Species
The Department of Conservation in Aotearoa New Zealand has three freshwater programmes situated on the West Coast of the South Island. We wish to share this knowledge with a group of rangitahi (youth) interested in conservation work. West Coast Freshwater Rangers will run through Stream Surveying 101 with the Project Moturoa Tauira on the pristine and sacred Arahura River (near Hokitika). We will talk about the significance of this catchment — ecologically and culturally — then spend the day setting up a survey site in a tributary of interest, including an electric fishing demonstration. Freshwater fish and macroinvertebrate identification will be a primary subject; students will be tested later in the evening during the survey! 🙂 Rangitahi will learn how freshwater rangers interpret survey sites for predicting which species will be occupying particular niche habitats within a stream.
We will flag out a 400m reach to spotlight survey for New Zealand’s migratory native species, particularly longfin eel/tuna and galaxiids such as shortjaw kōkopu. If time permits, we will set out fyke nets near the river mouth and identify/observe tuna the following morning.
