“…possibly lower than what would be seen in the field. Similar to previous studies, a clear circadian rhythm in heart rate was absent during the first ~3 days following surgery, which has been suggested to be an indicator for post-surgical stress and potentially reflects behavioural disturbances in swimming activity 3,48,49 .…”

Bio-logging devices can provide unique insights on the life of freely moving animals. However, implanting these devices often requires invasive surgery that causes stress and physiological sideeffects. While certain medications in connection to surgeries have therapeutic capacity, others may have aversive effects. Here, we hypothesized that the commonly prescribed prophylactic treatment with enrofloxacin would increase the physiological recovery rate and reduce the presence of systemic inflammation following the intraperitoneal implantation of a heart rate bio-logger in rainbow trout (Oncorhynchus mykiss). To assess post-surgical recovery, heart rate was recorded for 21 days in trout with or without enrofloxacin treatment. Contrary to our hypothesis, treated trout exhibited a prolonged recovery time and elevated resting heart rates during the first week of post-surgical recovery compared to untreated trout. In addition, an upregulated mRNA expression of TNFα in treated trout indicate a possible inflammatory response 21 days post-surgery. Interestingly, the experience level of the surgeon was observed to have a long-lasting impact on heart rate. In conclusion, our study showed no favorable effects of enrofloxacin treatment. Our findings highlight the importance of adequate postsurgical recovery times and surgical training with regards to improving the welfare of experimental animals and reliability of research outcomes. Across a wide range of disciplines, approximately 11.5 million experimental animals were used for research purposes within the member states of the European Union in 2011 1. While the vast majority of these animals are rodents (~80%), the proportion of ectotherms, including teleost fishes, is rapidly increasing 1. One expanding area within experimental fish research concerns the use of novel implantable electronic tags (e.g. bio-logging and bio-telemetric devices). The recent technological developments and use of bio-logging and bio-telemetric devices in aquatic organisms has been proposed to open up a 'panoramic window into the underwater world' 2. The use of these devices in freely swimming fish allow the continuous collection of high-resolution physiological and behavioural data (e.g. heart rate, blood flow and muscle activity) over long periods of time 3-9. Moreover, data from implanted fish swimming amongst conspecifics (i.e. focal animals) can provide important insights into relationships between physiological and behavioral traits across different social contexts in both natural and aquaculture settings 3,10. However, there are still challenges associated with the use of these implants in order to produce reliable high-quality data, as well as to safeguard the health and welfare of the experimental animal in accordance with the 3 R guidelines. First of all, introducing a foreign body into an animal may lead to expulsion or encapsulation of the implant, and secondly, the protective barrier of the epithelium is breached during surgery where after the wound can act as an entry-point for pathoge...

“…The slower growth of the physio-logging field could be due to the commercial unavailability of physiological sensors, or that the available sensors were too large, based on static-technologies, or required specialized surgical training and extensive knowledge of the anatomy and physiology of the animal for successful implantation. Despite these challenges, studies using bio-sensing tools have renewed the interest in physio-logging and attempted to understand the physiology of an animal through inference from their behavior (Wilson et al, 2002 ; Hooker et al, 2009 ; Goldbogen et al, 2011 , 2019b ; Kolarevic et al, 2016 ; Føre et al, 2018b ; Quick et al, 2020 ).…”

“…The behavior inside the cage of fishes, as a group of individuals of the same species is studied to determine parameters that are related to wellness, such as density population, average physical activity or growth of the specimen, among others. For example, in [ 6 , 7 ], researchers propose tagging a reduced set of individuals, called sentinel fishes, and from studying them infer the evaluation for the complete population. This approach requires at least two receivers strategically placed one at the top of the ocean fish cage and the other at the bottom of the cage.…”

In this paper, we present the design of a practical underwater sensor network for offshore fish farm cages. An overview of the current structure of an offshore fish farm, applied sensor network solutions, and their weaknesses are given. A mixed wireless–wired approach is proposed to mitigate the problem of wire breakage in underwater wired sensor networks. The approach is based on the serial arrangement of identical sections with wired and wireless interconnections areas. Wireless section alleviates underwater maintenance operations when cages are damaged. The analytical model of the proposed solution is studied in terms of maximum power transfer efficiency and the general formulas of the current in their transmitting antennas and sensor nodes are provided. Subsequently, based on simulations, the effects of parasitic resistance across the network are evaluated. A practical underwater sensor network to reach the 30 m depth with sensor nodes distanced 6 m is used to determine the proposal compliance with the ISO 11784/11785 HDX standard in its normal operation. Taking into account the cable breakage scenario, the results from experiments demonstrate the robustness of the proposed approach to keep running the sensor nodes that are located before the short circuit. Sensor node run time is reduced only 4.07% at most using standard values when a cable breakage occurs at the second deepest section.
