“…Based on this study, micro-processing technology could be advanced to the point where algorithms determined a priori (e.g. activity detection and identification) constantly calculate the key parameters, allocate event IDs as they occur and store or transmit the data (see Føre et al, 2011), thus providing the in situ delivery of activities and behaviour over time. This would only be possible if micro-processing uses little power.…”

“…In fish, acceleration metrics have been linked to heart rate and energy expenditure (Clark et al, 2010), spawning behaviour (Tsuda et al, 2006), activity (Kawabe et al, 2003a;Kawabe et al, 2003b) and, more recently, feeding behaviour (Føre et al, 2011). Generally, accelerometer tags continuously record data at some defined frequency or record a defined time-average of the data, which are either digitally stored or transmitted for subsequent postprocessing.…”

Summary Monitoring and measuring the behaviour and movement of aquatic animals in the wild is typically challenging, though micro-accelerometer (archival or telemetry) tags now provide the means to remotely identify and quantify behavioural states and rates such as resting, swimming, and migrating, and to estimate activity and energy budgets. Most studies use low frequency (≤32 Hz) accelerometer sampling due to battery and data-archiving constraints. In this study we assessed the effect of sampling frequency (aliasing) on activity detection probability using the great sculpin (Myoxocephalus polyacanthoceaphalus) as a model species. Feeding strikes and escape responses (fast-start activities) and spontaneous movements among 7 different great sculpin were triggered, observed and recorded using a tri-axial accelerometer sampling at 100 Hz and video records. We demonstrate that multiple parameters in the time and probability domains can statistically differentiate between activities with high detection (90%) and identification (80%) probabilities. Detection probability for feeding and escape activities decreased by 50% when sampling at <10 Hz. Our analyses illustrate additional problems associated with aliasing and how activity and energy-budget estimates can be compromised and misinterpreted. We recommend that high-frequency (>30 Hz) accelerometer sampling be used in similar lab and field studies. If battery and (or) data storage is limited, we also recommend archiving the events via an on-board algorithm that determines the highest likelihood and subsequent archiving of the various event-classes of interest.

“…El tubo central, hecho de lona o red de plancton, impide el paso de los copepoditos y permite generar un área libre de parásitos (Stien et al, 2015). De esta forma, los peces pueden llegar a la superficie y llenar de aire su vejiga natatoria, lo que convierte a estas jaulas en una buena opción en comparación con otras jaulas totalmente sumergidas, donde los peces no tienen acceso a la superficie (Føre et al, 2011), de allí que se desencadena una serie de efectos negativos sobre el crecimiento y comportamiento de los peces.…”

La salmonicultura constituye uno de los pilares de la economía chilena, pero debido al desarrollo de innumerables enfermedades, entre las que destaca la ectoparasitosis causada por Caligus rogercresseyi, los productores de salmón han disminuido sus índices productivos. Debido a esto, se están buscando sistemas alternos para cultivar salmones, siendo uno de ellos el cultivo de peces en aguas profundas, donde la temperatura es menor a la temperatura de la superficie, ya que C. rogercresseyi es un parásito cuyo ciclo de vida es dependiente de la temperatura del agua. El estudio detalla el comportamiento biológico del parásito y el efecto de la profundidad y temperatura de cultivo sobre el establecimiento del parásito en el hospedero.

“…This can for instance be monitoring fish behavior, but also to add information from environmental monitoring sensors like temperature, and oxygen into the feed control system (Chang et al, 2005;Føre et al, 2011;Soto-Zaraz ua et al, 2010). Hence, there is a general trend to include more information into the feeding system.…”
