-•	Video analysts must be thoroughly trained by a senior team member in the correct use of EventMeasure and/or fish identification. After the initial training period, the new video analyst will have two (2) weeks to examine a ‘testing video’ on their own. This ‘testing video’ is any video that has been previously analysed and checked for accuracy by a senior member of our team. To be deemed competent, analysts must obtain a minimum of 90% accuracy in the identification of species present in the ‘testing video’.
