“…When the tag releases and reaches the surface, the location is recorded via satellite, allowing for the creation of a movement pathway. We see potential for this method, in particular for deep-sea decapods (as in Davidson & Hussey 2019), where other telemetry methods may not be as feasible. This is particularly true as light-based geolocation will not perform at depths where sunlight is unavailable to the tags for estimating position.…”

“…For Dungeness crabs Cancer magister (also known as Metacarcinus magister), Burns et al (2020) drilled holes in the carapace and threaded monofilament to secure the tag with a crimp to secure the loop. Davidson & Hussey (2019) compared epoxy, looping leader through drilled holes, and tying a harness around the body axis for securing pop-up archival satellite telemetry tags and suggested the latter to be most appropriate for porcupine crabs.…”

“…Scales of movements by adult decapods vary widely, from meters to >100 km (Groeneveld & Branch 2002, Allen et al 2015, Davidson & Hussey 2019), encompassing a variety of complex behaviours and habitats (Pittman & McAlpine 2003). The movement ecology of species also varies among individuals, life history stages, and populations, and a comprehensive understanding of these spatial behaviours is required for effective conservation management.…”

Decapod crustaceans are ecologically and economically important invertebrates but are vulnerable to anthropogenic pressures and climate change. Understanding their spatial ecology is essential for their management and conservation, with telemetry emerging as a useful tool to quantify space-use and movements. Here, we synthesized the use of telemetry to study decapods among articles published from 1971 to 2019 (n = 102 studies), by taxonomic group of the study species, study location, objectives, number of animals tagged and their tag recovery rate, types (and trends) of telemetry used, and IUCN conservation status. These studies revealed insight into the behaviours and roles of decapods across habitats and geographic regions. The most common study species were crayfish and lobsters (41%, Astacidea), and these studies also had the highest number of individuals tagged per study (mean = 149 individuals). Most studies (86%) were conducted in the northern hemisphere. Acoustic tags were the most commonly used equipment (66% of studies) and were first employed in 1971, followed by radio-telemetry (mid-1990s), passive integrated transponders (mid-2000s), and data storage tags (late 2000s). Almost half (48%) of studies focused on species that had a conservation status of Least Concern, perhaps reflecting an applied science focus on animals of commercial interest rather than conservation importance. The positive allometric relationship between body length and movement rate (exponent = 0.86) demonstrates the type of broader ecological insight that combining these studies can provide. Tracking decapod movements will likely become increasingly important for managing fisheries, protecting sensitive species, and understanding invasion biology.
