This document discusses new fishfinder technology being developed by Humminbird that can identify and locate individual fish species using their unique acoustic signatures, even distinguishing between types of fish near each other. It describes how the technology works and some of its capabilities. It also discusses potential issues with the technology, such as whether it makes fishing too easy or could overstress fish populations if widely used. Some commercial fishermen see benefits but also risks to resources from this advanced fishfinding system.

Is "having all this" a lot of? That's the question being asked about offshore fishing electronics, of
course, if the newest technology makes its distance to actual products, the answer's going to get
even trickier.
Let's check out what's draining the well-equipped sportfishing boat's battery today. First, there are
the sonar systems--or striped bass finder--Loran-C along with its successor, global positioning
system (GPS). And then there are the depth-reading temperature gauges and themocline monitors.
You will find oxygen monitors. You will find color and clarity spectrum gauges.

y arriving at a bait store close to you within the not-too-distant future, a Humminbird Fishfinder
Depth Finder system that can precisely locate tuna through the sound they are. The particular
species you desire, while not just goldfish generally speaking. It can even tell a blue from the striper
holding on the same drop-off.
The reality that certain pet fish make characteristic sounds may come as no surprise (how can you
think "grunts" got their name). But over the past handful of decades, scientists have found that every
marine species--as a result of and including mussels, shrimp and clams--emits species-specific
sounds. Many of them, needless to say, are outside the range of human hearing.
Or were.

2. Water is a wonderful medium for the transmission of sound waves--far better than air. At 60 it
carries sound in a speed of 4,800 feet per second. Depending on the that fact, technology will be
developed that makes it possible to detect a fish's sonic "signature" from great distances--as in miles,
not feet. These products. Humminbird's 1159ci HD DI gives you incredibly detailed views of the
bottom and structure below your boat on a large 10.4" LED backlit color display with pristine, 800H
x 600V LCD pixel clarity. Down Imaging® and DualBeam PLUS sonar with up to 4000 Watts PTP
power output, GPS Chartplotting with built-in Humminbird ContourXD maps, and Ethernet
Networking capabilities. Includes unit cover and in-dash mounting kit. Maximize your angling
experience with the Humminbird 1159ci HD DI Combo fishfinder system.also filter out unwanted
noise (boat motors, fishfinder signals, turbines, water turbulence, other species, etc.). Insert the chip
that reads "striper" and, braaap, there's one, about 14 pounds. No--hold on--the screen implies that
it's swimming clear of you. Braap. Okay! Here's a good 20-pounder, coming ideal for you, at 11
o'clock. Take him!
Of course, if a device can pinpoint and filter out a species-specific sonic signature, the length of time
do you think it will likely be before the next phase is taken, which is to produce sonic signatures. So
once a fisherman has a target, he'll have the ability to create a sonic chumline, broadcasting the
signature of any school of menhaden, for instance, to bring in a major striper. or even better, a blue
marlin. Think about those billfisherman who often troll for several days with out a hook-up!

sonar-instructions this is theoretically possible, says
Paul Yelinek, president of Seaway Technologies of
Port Richey, Fla., which includes done considerable
research in this region and has already made several
patent applications.
So how does such technological capability square
with the very idea of "fair chase"? A backlash has
already begun to develop against technology inside
the outdoors. This latest advance is sure to strike
even more people as excessive.

the leading problems in marine fisheries conservation is "by-catch" the inevitable netting or
longlining of gamefish by commercial fishermen seeking plentiful food some Humminbird Fishfinder
Depth Finder seafood, Let's play devil's advocate for the minute. By-catch is definitely the drowning
and netting of porpoises by commercial tuna boats, the most publicized illustration of.
Now let's suppose a system installed on a tuna trawler could generate the sonic signature of the
killer whale. Because killer whales take advantage of porpoise, who recognize the whale's sound as
dangerous, while tuna tend not to, that will cause any porpoise in the region to bail out. Seaway
Technologies has applied for a patent with an "infrasonic" system designed specifically for driving

3. porpoise from the areas through which tuna boats work. Is this type of "management'' more
acceptable--more potent--than banning gill nets?
Commercial fishermen themselves are of two minds in terms of this new technology. Jerry Sansom,
executive director in the Organized Fishermen of Florida (OFF), one of the world's largest
commercial offshore fishing organizations, says, "Although I can visualize by investing in this new
fish-finding system we could eliminate spotter planes and minimize expenses when seeking out
schools of offshore saltwater fish species, I could also see where our resources could become
stressed through its wide usage."
