The relationship between behavioral thermoregulation and physiological recovery following exhaustive exercise is not well understood. Behavioral could be beneficial for recovery; example, selection of cooler temperatures reduce maintenance metabolic cost to preserve aerobic scope cost, or warmer accelerate metabolites. While post-exercise has been observed in lizards frogs, little known about its importance fish. We examined the influence temperature on rate, thermal preference, metabolite concentrations juvenile brook char (Salvelinus fontinalis). Fish were acclimated exercised at 15°C, then recovered either 15°C 10°C while their rate was measured via respirometry. Metabolite fish after under one three treatments (to simulate various scenarios): (i) 6 h (ii) 10°C, (iii) 3 followed by 15°C. Thermal preference quantified using a static system (15°C vs. 10°C). Metabolic rates returned resting faster compared with although there tradeoff delayed recovery. Specifically, plasma osmolality, lactate, muscle lactate remained elevated entire period recovering whereas these parameters levels from other two groups. Regardless, did exhibit clear (i.e., overall consistently prefer temperature) prioritize process. advantage may trade off against temperatures, lessening usefulness as strategy

The welfare of fishes and aquatic invertebrates is important, several jurisdictions have included these taxa under regulation in recent years. Regulation requires use scientifically validated criteria. This why applying Mertonian skepticism toward claims for sentience pain sound prudent, particularly when those are used to justify legislation regulating the taxa. Enacting without strong scientific evidence a societal political choice that risks creating interpretational problems as well major policy challenges, including potential generate significant unintended consequences. In contrast, more rigorous science-based approach organisms based on verified, measurable endpoints likely result "win-win" scenarios minimize risk negative impacts all stakeholders, fish invertebrates. authors identify supporters animal welfare, emphasize this issue not about choosing between no invertebrates, but rather ensure important decisions their robust evidence.

Based on the homemade Physiological and Ecological Comprehensive Analysis System for Aquatic Animals (PECA-BES01), this study compared behavioral responses of koi carp (Cyprinus carpio) at three temperature gradients using two monitoring techniques as follows: infrared tracking quadrupole impedance. The experiment employed comprehensive strength (with tracked coordinates converted to swimming velocity data) reflect changes. Within a certain range, increased with increasing temperature, which indicated heightened activity. average during light conditions (over gradients) were greater than dark conditions. circadian rhythm becomes unstable high temperatures, shows abnormal periodicity earlier occurrences diurnal time points. Results from system's methods largely consistent confirmed reliability PECA-BES01 in aquatic organism behavior. Simultaneously, each technologies has its own characteristics. Quadrupole impedance can be used monitor response fish different water depths, whereas flow velocities. Therefore, both are effective behavior widely applied. This provides scientific support cultivation other species aquaculture, while also aiming deliver high-quality methodology online organisms.

In this study, we investigated whether Nile tilapia (Oreochromis niloticus), a commonly farmed species worldwide, prefer artificial water hyacinth - easy-to-build and inexpensive as structural enrichment by investigating if different common farm stocking densities affect such response. We tested juveniles under three (12, 16, or 20 fish per aquarium) in both the absence (control groups) presence (artificial treatments) of for 6 weeks. filmed every week, when was spread it concentrated one aquarium section. then analyzed their preference responses based on number recorded each preferred enrichment, strong response that may override an initial another area. Although all showed hyacinth, intensity stronger at highest density. These findings indicate is highly should be implemented farming conditions, particularly higher densities.

ABSTRACT Neuropeptides are highly variable but widely conserved molecules, the main functions of which regulation and coordination physiological processes behaviors. They synthesized in nervous system generally act on other neuronal non‐neuronal tissues or organs. In recent years, diverse neuropeptide isoforms their receptors have been identified different fish species, regulating neuroendocrine (e.g., corticotropin‐releasing hormone arginine vasotocin), immune vasoactive intestinal polypeptide somatostatin), digestive Y), reproductive isotocin) systems, as well commensal microbiota. Interestingly, all these carried out by neuropeptides integrated into manifested externally behavior affective states fish, thus having an impact modulation actions. this sense, monitoring may represent a new approach to assess animal welfare, targeting both aspects fish. Therefore, although there many studies investigating action wide range paradigms, especially mammals, study within welfare framework is scarce. To best our knowledge, first review that gathers integrates up‐to‐date information from perspective. review, we summarize current findings discuss possible implication emotional state therefore welfare.

Studies show that Atlantic salmon in captivity adjust their distribution sea cages based on environmental gradients like temperature, waves, and photoperiod. This study used a computer vision algorithm at three marine farms to analyse fish group swimming behaviour termed "activity" (measured percent), which includes abundance, speed, shoal cohesion. The activity metric inferred the depth of main was analysed with respect conditions explore potential behavioural drivers assess changes response stressor, storm event. During winter conditions, Farms A B showed distinct thermal stratification, demonstrating preference for warmer lower water column (39.6 ± 15.3% 27.5 10.2%) over upper (16.3 5.7% 18 3.3%; p < 0.001). At Farm C, thermally homogenous water, similarly distributed between (18.2 6.9%) (17.7 7.6%) column. Severe weather increased wave heights, influencing horizontal differently C. B, deeper site, remained avoided surface while shallower cages, they moved toward side cage nearest centre farm, presumably less exposed due nearby cages. Understanding responses can inform management practices, using cameras associated algorithms offers powerful, non-invasive tool continuously monitoring safeguarding health welfare.
