Product Details Long life and large memory: This fish archival tag can store 1.4 million measurements in total and measures at a user defined interval, as fast as every second. Memory and battery life can last for 2.5 years if sampling at a 2 minute interval. The tag size is 39.4 mm x 13 mm, weighing 13 grams. The logger can be set to record with multiple intervals, shifting between different intervals during the measuring period. Application: The DST milli-TD data storage tag is designed as an economical fish archival tag for migration and dive behavioral studies of fish and marine animals over a long period of time. The tag can be implanted or attached externally. It can also be used as a standalone temperature depth logger in various situations. Depth sensors from shallow to deeper water: DST milli-TD tag can be calibrated up to 800 meters. Customers choose between depth calibration up to: 50 m, 100 m, 250 m, 500 m or 800 m. The shallower the range the better the resolution and accuracy. Fish implantation or external attachment: The logger is designed as an implantable tag and can be implanted in the abdominal cavity. It can also be attached externally on a fish or marine animal using a tag holder kit, ensuring easier and safer attachment. Customized text on housing: For tag and release of animals into the wild, the tags can have a customized text on the housing, for recapture purposes. It is important to have the return information when the tags are used on commercially fished species, so that fishermen can return a tag with valuable data to the scientist. Normally there is a reward for return of a tag. Spaghetti tag for spotting fish: When the DST logger is implanted in fish it is possible to have a yellow plastic tube, a spaghetti tag, attached to the DST. The tube sticks to the exterior of the fish, making it easier for fishermen to spot the tagged fish. Using the logger Simple in Use, From Setup to Data Retrieval: The logger and the accompanying items are designed for ease of use throughout the research process, from setting up the logger, attaching it, to retrieving and analysing the data. The logger is supported by the SeaStar software and a Communication Box which have to be purchased with the first order. Programming the Logger: To set the logger for starting measurements it is placed into the Communication Box that connects with a USB cable to a PC computer. In the SeaStar software, the user sets the start time, start date and sampling interval before starting the tag for measuring. The tag synchronizes its internal clock with the date & time on the computer being used. Single or multiple intervals: There are two modes for sampling, either at a single interval throughout the period or multiple intervals. When choosing multiple intervals programming it is possible to define up to seven different intervals and number of measurements for each interval. Shifting between wide and narrow intervals can help in extending the measuring period due to memory limitation and have more frequent measurements during certain time periods, for example spawning periods. Memory and Battery Life Calculations: The software automatically calculates when memory fills based on certain interval settings, making it easier for the user to decide how to program the tag. Estimation on battery consumption during that time period is also calculated. Uploading the Data: After fish recapture, the tag is inserted into the communication box and the recorded data is uploaded to the software. The results are displayed both in graphic and tabular form and the data can be exported to other programs. The time series data shows each measurement with its own time stamp. Long battery life: After data retrieval the data storage tag can be re-used, as long as the batteries inside last. Battery life estimation is always reported upon connection with the tag. Due to the low energy consumption circuitry design the battery life can be several years, depending on usage and sampling interval used.
