Innovation is always a work-in-progress at HTI. Our research and development team offers you a glimpse
of just a few priorities in the works today. |

Why it matters: Sub-yearling Chinook salmon are small, and to effectively monitor them in behavioral studies their tags need to be small. Although HTI offers the smallest tags commercially available, we’re working to make them smaller.

Why it matters: Some studies require only a day's worth of data, others a season, and some - years. While tag life directly correlates to tag size, we’re working to increase battery life by 2-3 times in our current tag sizes. Currently, development is in progress to apply long-life technology to all Model 795 Acoustic tags.

Why it matters: We’ve been looking at various environmental factors to understand their influence on fish behavior. For example, the 3D tracks of juvenile salmon approaching a dam were compared with water velocity profiles. Many fish paths were observed to closely follow velocity “shear zones”, where there was a sharp gradient in water velocity. Visual animation and presentation techniques considering attributes of the fish and the surrounding environment allowed a better understanding of why fish may select specific
passage routes over a dam. Data visualization and integration techniques, combined with the ability to
track fish in 3D space, can provide powerful tools for understanding the factors affecting fish distribution
and behavior. |
