Fish Farming, Fish Tagging
Pelago has a range of miniature data loggers which can
be used in many applications and environments including Fishing farming,
freezer temperature measurement, temperature sensitive products, sterilisation
and process control, Industrial applications.
iButton are miniture portable and cost effective data
collection devices ideally suited to these types of application
The iBTags are based on the iButton® family of products
manufactured by Dallas Semiconductors. The iBTags come in several sizes
of submersible temperature archival tag, iBKrill, iBBass and iBCod.
The basic iButton® metal can has the lowest cost and is the smallest
temperature logger that can be found with-in the industry. It is widely
used for traceability of perishable goods.
Each size can incorporates one electronic circuit with different specifications
as shown in the table below.
Depth rating is 600 meters for all iBtags except the iButton metal can,
which is not submersible and is used for dry temperature measurements

The iBCod is the biggest of all three iBTags but also
the least expensive. It is reinforced with solid titanium plates and
over molded in a tough polyurethane casing that can take a lot of rough
It should be the first choice for the bigger fish or as
oceanographic instrumentation to monitor lake or stream temperature.
It is also less expensive than the smaller iBBass and iBKrill.
It is presently used very successfully for adult cod tagging
in the Gulf of St-Lawrence in Canada and for adult salmon in the US

The iBTags are miniature temperature archival tags used
for tagging fish and small animal such as bat. They come in four sizes
with a choice of loggers with different resolution, precision and memory.
Refer to our PDF technical document for detailed information on the
specifications and part numbers.
The iBTags can be programmed and data downloaded by the
user. A roll over option allows the user to keep the first measurements
in memory or to replace them with the latest values. An histogram feature
of the device will keep the count of the erased and logged measurements.
The standard logger comes with a -5 to 26°C range
and a 0.125°C resolution. The precision of +/-1 C can be improved
greatly by individual calibration.
The electronic used in the iBTag comes from the Thermochron,
a device used extensively in scientific and industrial applications.
It is fabricated in very high quantities which brings its price very
low. It has a lot of following in scientific community and is the object
of several discussion forum on the internet.,
The iBTags were first used on cod tagged in the golf of
St-Laurence in august 2001. Up to a hundred loggers were successfully
recovered before the cod fishing moratorium in 2003.
