Services
We have
over twenty years of experience tracking movements,
behaviour and physiological parameters of free-swimming
wild fish. Passive Integrated Transponders (PIT), when utilized in
fisheries studies, can facilitate the identification and
tracking of individual fish without impeding or obstructing the normal
biological behaviour of the tagged animal for it's entire
life. PIT tags are a reliable,
efficient and effective means for monitoring fish
movements and habitat utilization over long periods
of time.
We can
design and build PIT tracking antennas to suit specific
site or structure specifications for both full-duplex and
half-duplex tag types. A single antenna can be utilized to
record fish passage, or several antennas can be
synchronized together to record fish attraction and
passage efficiency, for example, in fishways at dams.
Tracking data are logged on-site and transmitted to the
internet and by ftp for subsequent analysis.
PIT
antennas like the one installed at the Mannheim weir in
the
Grand River, Kitchener, Ontario
(shown above) can be linked with our
BRAVO system to also record and broadcast video and environmental data.
The
following scientific studies were conducted using Passive
Integrated Transponders (134 Khz) to collect movement
information, habitat characterization or behavioural data
from tagged fishes:
