HTI is introducing several new advanced fisheries technologies in the near future, including upgraded split-beam echo sounders being released in February 2013, new acoustic tags with lifespans of up to 3 years debuting in Spring 2013, prototypes for predation tags in Spring 2013, and autonomous data loggers debuting in Fall 2013. HTI specializes in acoustic technologies for fisheries research and has helped agencies like WSDOT monitor fish behavior, passage, and survival around bridges and other structures.

6. Who we are & what we do.
HTI is a dedicated group of
scientists, engineers & techs
specializing in acoustic technology
for fisheries assessments.
We’re your "local" global experts
in monitoring fish survival, passage & behavior.
We design, engineer & manufacture
acoustic equipment & software in Seattle.
We also conduct studies, provide
analysis reports & support everyday.
For the Washington State
Department of Transportation

7. We are different.
We built our technology on a foundation of understanding
the principles of sound in water.
We are local.
Working at the University of Washington in the early 1970's,
Dr. Ehrenberg’s developed the first split-beam system for
fisheries assessment. HTI equipment originated out of this
technology.
In 1997, we funded & designed acoustic tag systems to
track fish in fine-scale 3D. Driven by client needs and the
feedback from our team of in-house consultants, HTI
continues to evolve both technologies. Both are applied in
freshwater & marine environments all over the world.

14. What sets HTI apart from other acoustic technologies.
A non-intrusive and non-destructive (e.g., for working
with endangered species) means of monitoring
presence/absence, entrainment, population sizes,
spatial distributions and trends.
Orders of magnitude greater sampling capabilities
compared to traditional techniques.
A cost-effective means for scientific-grade research.
Delivers statistically robust, high resolution samples.

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 other
systems.
Remote access to echo integration, target strength
(acoustic size), three-dimensional target tracking (with
target strength calculation per tracked fish), and echo
counting in real-time.
Simultaneously sample multiple acoustic transducers
(fast multiplexing).

Fully programmable acoustic tags.
Access remotely via cell modem or
WiFi.
Unique tag signal design allows
hundreds of tags to be tracked in one
area at one time.
A single hydrophone can determine
movement patterns & behavior (e.g., a
tagged fish moving toward or away
from a hydrophone can be observed
using one hydrophone).

34. Bonus Slides: Details about What's Next
Hydroacoustic Echo Sounder Advances – Releasing February 2012
Our latest advance in hydroacoustics with Window 7™-compatibility
completes our new monitor control boards with efficient raw data
management and other asked-for features and upgrades.
New LY Acoustic Tags - Spring 2013
The Model 795 LY tag is the latest addition to our L-series acoustic tag
product line. Powered by a single lithium cell, this acoustic tag is ideal for
longer term studies (possibly 2+ years or more depending upon needed
resolution). This acoustic tag is designed for tracking predatory fish over
extended periods of time and exhibits the same signal strength and
resolution as other larger L-series acoustic tags. Like all HTI acoustic tags,
the LY Tag comes with optional encapsulated PIT technology providing tag
identification long after the tag battery has expired.

35. What’s next in advanced fisheries technology.
Autonomous Data Loggers - Fall 2013
HTI's newest addition to this data logger suite will be a completely
submersible, single-frequency receiver and data logger. Being
completely autonomous and simple to use, this new data logger can be
put in the water in the area of interest and left for the life of the
rechargeable lithium battery pack. Employing the same technology as
the Model 300-Series Data Loggers, it is also fully compatible with all
HTI acoustic systems. By virtue of the proprietary tag encoding, like all
of HTI acoustic tag system, it is immune to tag collisions. Comparable
to a VEMCO VR2, HTI's autonomous data logger can simultaneously
detect and identify literally hundreds of acoustic tags at the same time
in the array.
