Data management and analysis techniques are in their infancy and few standardised techniques exist, but they provide many advantages for studying aquatic animal movement patterns, but also has limitations and provides unique difficulties for users.

This study compared patterns in acoustic detections from tagged cuttlefish Sepia apama and several fixed-location control tags, and used these data to highlight the danger of misinterpreting patterns in the absence of adequate controls.

Modal Progression Analysis of length-frequency data is the most common method for examining in situ octopus growth, and there may be basic differences in the mechanisms of octopus muscle growth compared with that of other cephalopods.
Tolerance limit for fish growth exceeded by warming waters

Evidence shows that warming can eventually exceed physiological limits for a fish species—the banded morwong—in the Tasman Sea, and provides evidence consistent with this prediction for a marine fish (Cheilodactylus spectabilis) in the Tasmania Sea.

Evidence is presented that suggests seismic surveys cause significant mortality to zooplankton populations and there is a significant and unacknowledged potential for ocean ecosystem function and productivity to be negatively impacted by present seismic technology.

A large-scale synthesis of survival and movement rates of free-ranging juvenile salmon across four species, 13 river watersheds, and 44 release groups of salmon smolts in rivers and coastal ocean waters indicates that smolt survival was not strongly related to size at release, and tag burden did not appear to strongly reduce the survival of smaller animals.
Response of Atlantic salmon Salmo salar to temperature and dissolved oxygen extremes established using animal-borne environmental sensors

The results show that vertical habitat contraction could likely be a significant consequence of climate change if the reduction in DO outpaces the increase in hypoxia tolerance through local adaptation, and highlight that site-specific environmental conditions and stock-specific tolerance thresholds may need to be considered when determining stocking densities.
