Monitoring options for marine: fish and invertebrates

You are here: Home > By species type > Marine > Fish / Invertebrates

There are a variety of factors to consider when choosing the best technology and equipment to monitor marine fish and invertebrates.  To ensure that you’re making the best choice for your study, we recommend that you speak with a Lotek representative. 

Option 1: We’ll call you.
Start by using our Project Profile form to send us the details of your study.  Once you complete the form and click the Send button, a Lotek representative will contact you shortly to discuss your project and recommend the best system, based on the details that you’ve provided to us.
  
Option 2: You call us.
Start by reviewing the product descriptions on this web site, and then call us to confirm your choices and place your order. To better prepare you for that conversation, here is a brief overview of some of the main factors that will influence your choice:
Do you want to use tags that passively store data or actively transmit data?

Data storage (archival) tags are referred to as “passive” because the data that they collect on time, temperature and depth is stored in the tag for retrieval at a later date. Typically, researchers interested in long-term and/or long-distance data about their animals will choose archival tags.

Transmitting tags, on the other hand, are referred to as “active” because they actively emit signals which you must detect either in real-time or by using a datalogging receiver station. Typically, researchers interested in data from a specific location or for a set period of time will choose actively transmitting tags to track their study subjects.

 

If passively storing tags:
If you’ve selected archival tags, the next step is to determine what type of data you’d like to collect.

Are you interested in recording both horizontal and vertical movements, or just vertical movements?

There are two main categories of Lotek archival tags: Temperature Depth Recorders that can record data on the vertical movements of your subjects, and Geolocators that can also record data on their horizontal movements.

  • If both horizontal and vertical:  If you need long-distance migratory information about your subjects, see our archival geolocation tags.

  • If just vertical:  If temperature and depth information is sufficient for your study, see our archival temperature depth recorders.

Other considerations ...
There are also other factors that will influence your choice of monitoring technology.  Please ask your Lotek representative about additional factors such as:

  • Tag size & weight:  Lotek archival tags come in a variety of sizes.  Your Lotek rep will be able to help you select the best size tag for your study.

  • Programming flexibility:  Many Lotek tags also offer options such as user selectable data resolution, and more.  Your Lotek rep can explain all of the options and recommend the best configuration for your study.

If actively transmitting tags:
If you’ve selected transmitting tags, the best technology for telemetry in a marine environment is an acoustic system.  The next step is to determine which acoustic system is best for your study.

Are you interested in mobile tracking or stationary (fixed-position) tracking?

With mobile tracking systems, the receiving equipment is typically on a boat that moves around the study area to detect the subjects’ acoustic signals.  With stationary tracking, those signals are detected by equipment situated in fixed positions within the study area.

  • If mobile tracking:  If you want to track fish or invertebrates using a mobile acoustic system, see the MAP RT section of our MAP 600 Series page.

  • If stationary tracking:  If you plan on using fixed-station datalogging, see our WHS 2000 and WHS 3000 wireless hydrophone systems.

Other considerations ...
There are also other factors that will influence your choice of acoustic monitoring equipment.  Please ask your Lotek representative about additional factors such as:

  • Tag size & weight:  Lotek acoustic tags come in a variety of sizes.  Your Lotek rep will be able to help you select the best size tag for your study.

  • Detection range:  The greater the tag’s output power, the greater its detection range.  But the greater its power, the larger the tag.  Again, we can help you balance all of the factors that need to be considered when it comes to tag size, life and detection range.

  • Operational life:  Depending on the specific model, Lotek acoustic tags can continue operating for days, weeks or months.  The model you choose should be the one that best matches your study’s objectives.

  • Programming flexibility:  Many Lotek tags also offer options such as flexible transmit-burst repetition rates, standard or enhanced longevity, and more.  Your Lotek rep can explain all of the options and recommend the best configuration for your study.

  • Sensor data:  In addition to transmitting signals for detection, many of our tags can also transmit additional sensor data on depth, motion and temperature if required for your study.  See our Acoustic Sensor Transmitters page for details and options.


If you’d like a Lotek representative to help you choose the best system for your study, you can either use this Project Profile form to send us the details of your study, or simply contact us by email or telephone.  We look forward to hearing from you.
