DSTs are originally developed for tagging fish and
other animals living in saline and fresh waters.
DSTs are used in analyzing e.g. the tagged animal’s
migration, distribution, feeding and spawning
behavior, vertical/horizontal movements or
geographic location. The loggers can be fastened
externally or implanted in the animal. The DST
housing is made of alumina, a biocompatible ceramic
material that is not recognized as a foreign
body by the animal’s organism. DSTs can also
be used as standalone loggers for environmental
monitoring or attached to fishing gear and other
underwater equipment.
All measured data is stored in the logger’s internal
memory. When the logger is recovered after the
measuring period, recorded data is uploaded in
the supporting SeaStar software where it can be
viewed and analyzed in graphic and tabular form.
The same logger can be reused as long as the
battery lasts.
For recapture purposes customers can define
their own text on the logger housing, giving information
on e.g. where to return the tag, reward (if
any), etc. If tagged internally, Star-Oddi can deliver
the tag with a colorful plastic tube attached.
The external plastic tube can easily be identified
by e.g. fishermen.
PRODUCT FAMILY
The DST product family features three different
sizes: centi, milli and micro. The DST loggers vary
in size, memory size, battery life and sensors. |
 |
SeaStar (for Windows©) is the graphic supporting software for
all Star-Oddi loggers. The user sets the start time, start date and
sampling interval in SeaStar before starting the recorder. Sampling
interval can be set in second(s), minute(s) and/or hour(s).
With default programming all parameters are recorded at the same
time. Optionally, it is possible to define different sampling intervals
for the parameters (primary and secondary parameters/parameter
pairs with different sampling frequency). With this option memory
partitioning can be customized according to individual preferences.
DSTs can also be programmed with up to 7 different sampling
intervals. These intervals can then be defined in a preferred order
within a measurement sequence. Number of measurements is
defined for each interval. The measurement sequence is repeated
until the memory is full or the logger retrieved. Programming several
sampling intervals in a sequence can be useful when more/fewer
measurements are needed at certain time periods.
After recovering the DST(s), recorded data is uploaded in SeaStar,
where the results can be analyzed in graphic and tabular form along
with date and time. The logger can be reprogrammed and reused
as long as the battery lasts. Data can be retrieved even after the
logger’s battery is empty. |
| The Communication Box works as an interface for data transfer
between the DSTs and a PC. Communication between a DST
and the Communication Box is wireless. The Communication
Box is connected to a PC using either a USB or RS-232C
9 pin serial cable. When a logger is connected to a PC
the logger is powered through the Communication Box
and is not using its internal battery. |
 |
| There is a wide range of accessories for Star-Oddi
products available. For fish and other animal tagging
we provide special fastening and tag holder kits that
make the tagging process easier and safer.
When DSTs are used as standalone loggers in harsh
environments it is advised to use protective housings
to protect the loggers from knocks and dents.
Star-Oddi offers plastic protective housings for all
logger sizes. Star-Oddi also manufactures a special
adjustable protective housing especially designed for
DSTs with tilt and magnetic field strength sensors. |
