  • 1. What’s Next in AdvancedFisheries Research Technology Sam Johnston & Bruce Ransom HTI Hydroacoustic Technology, Inc. 715 NE Northlake Way, Seattle, WA 98105 USA support@HTIsonar.com Presented January 8, 2013 © 2013 Hydroacoustic Technology, Inc.
  • 2. Today’s PresentationHow you may already be familiar with HTI.Who we are & what we do.What sets HTI apart from other technologies.What’s next in advanced fisheries technology.How HTI can help your WSDOT team accomplish environmental objectives. For the Washington State Department of Transportation

  • 6. Who we are & what we do.HTI is a dedicated group ofscientists, engineers & techsspecializing in acoustic technologyfor fisheries assessments.We’re your "local" global expertsin monitoring fish survival, passage & behavior.We design, engineer & manufactureacoustic equipment & software in Seattle.We also conduct studies, provideanalysis reports & support everyday. For the Washington State Department of Transportation
  • 7. We are different.We built our technology on a foundation of understandingthe principles of sound in water.We are local.Working at the University of Washington in the early 1970s,Dr. Ehrenberg’s developed the first split-beam system forfisheries assessment. HTI equipment originated out of thistechnology.In 1997, we funded & designed acoustic tag systems totrack fish in fine-scale 3D. Driven by client needs and thefeedback from our team of in-house consultants, HTIcontinues to evolve both technologies. Both are applied infreshwater & marine environments all over the world.

  • 14. What sets HTI apart from other acoustic technologies.A non-intrusive and non-destructive (e.g., for workingwith endangered species) means of monitoringpresence/absence, entrainment, population sizes,spatial distributions and trends.Orders of magnitude greater sampling capabilitiescompared to traditional techniques.A cost-effective means for scientific-grade research.Delivers statistically robust, high resolution samples. For the Washington State Department of Transportation
  • 15. What sets HTI apart from other acoustic technologies.Only HTI and the U.S. Navy employ the FM Slide Chirp– improving detection range by 2.6 times that of othersystems.Remote access to echo integration, target strength(acoustic size), three-dimensional target tracking (withtarget strength calculation per tracked fish), and echocounting in real-time.Simultaneously sample multiple acoustic transducers(fast multiplexing).

  • 33. Bonus Slides: Details about Whats NextHydroacoustic Echo Sounder Advances – Releasing February 2012Our latest advance in hydroacoustics with Window 7™-compatibilitycompletes our new monitor control boards with efficient raw datamanagement and other asked-for features and upgrades.New LY Acoustic Tags - Spring 2013The Model 795 LY tag is the latest addition to our L-series acoustic tagproduct line. Powered by a single lithium cell, this acoustic tag is ideal forlonger term studies (possibly 2+ years or more depending upon neededresolution). This acoustic tag is designed for tracking predatory fish overextended periods of time and exhibits the same signal strength andresolution as other larger L-series acoustic tags. Like all HTI acoustic tags,the LY Tag comes with optional encapsulated PIT technology providing tagidentification long after the tag battery has expired. For the Washington State Department of Transportation
  • 34. What’s next in advanced fisheries technology.Autonomous Data Loggers - Fall 2013HTIs newest addition to this data logger suite will be a completelysubmersible, single-frequency receiver and data logger. Beingcompletely autonomous and simple to use, this new data logger can beput in the water in the area of interest and left for the life of therechargeable lithium battery pack. Employing the same technology asthe Model 300-Series Data Loggers, it is also fully compatible with allHTI acoustic systems. By virtue of the proprietary tag encoding, like allof HTI acoustic tag system, it is immune to tag collisions. Comparableto a VEMCO VR2, HTIs autonomous data logger can simultaneouslydetect and identify literally hundreds of acoustic tags at the same timein the array.
