“…Cortisol is a vital and conserved stress hormone, and it is considered one of the indicators reflecting the stress status of animals, including crustaceans. Elevated plasma cortisol levels, mediated by stress, can reduce the energy required for muscle growth in animals, including crustaceans, leading to growth inhibition and decreased survival rates [41][42][43]. Changes in light conditions represent a stressor for aquatic animals, triggering stress responses and inducing cortisol synthesis and release [19,[44][45][46].…”

The spectrum is a key environmental factor, and light-emitting diodes (LEDs) can influence the growth and development of crustaceans by altering the composition of the spectrum. This study conducted a 30-day experiment to investigate the effects of five LED spectra (red, yellow, blue, green, and white light) on the growth, antioxidant and immune enzyme activities, stress hormone levels, and the expression of α-amylase (α-AMY), ecdysone receptor (EcR) and retinoid X receptor (RXR) genes in juvenile redclaw crayfish (Cherax quadricarinatus). The results show that the survival rate of juveniles is markedly higher in the yellow and red-light groups than in the other three groups (P<0.05). The green light group exhibits the lowest survival rate, yet it demonstrates the highest weight gain rate and specific growth rate. Regarding enzyme activity and hormone levels, the yellow light group shows the lowest malondialdehyde content, with higher superoxide dismutase and acid phosphatase activity than the other groups; no significant differences are observed in lysozyme activity among the groups (P>0.05). The melatonin content in the green and blue light groups is significantly higher than that in the other three groups (P<0.01). In terms of growth gene expression, the expression of α-AMY, EcR, and RXR in juvenile C. quadricarinatus is regulated by the spectrum. In conclusion, when raised under the yellow light spectrum, juvenile C. quadricarinatus displays elevated survival rates, rapid growth, and robust antioxidant and immune defenses. This study provides important technical parameters for optimizing and enhancing the industrial cultivation of juvenile C. quadricarinatus.

“…Scale cortisol content has been demonstrated as providing a reliable biomarker of chronic stress across a range of different fish species from both freshwater and marine environments (e.g. Carbajal et al, 2018, 2019a,b; Laberge et al, 2019; Lebigre et al, 2022l Vercauteren et al, 2022). Applying this biomarker here to two freshwater fishes exposed to catch-and-release angling, we initially developed proxies of angling capture vulnerability for the two study populations, where we assumed that fish with higher capture vulnerabilities would have had higher recapture rates in preceding months and, given individual angling capture events represent a short-term physiologically stressful event (Cooke et al, 2013), we hypothesised that these fishes would then have higher accumulations of cortisol in their scales.…”

“…Carbajal et al (2018, 2019a,b) revealed that scale cortisol levels are influenced by mid-term, energetically intense periods rather than long-term stressors, thus can be considered as a biomarker that provides retrospective hormonal measurements from fishes and time periods that are usually difficult or impossible to obtain. Scales have recently been applied to provide a retrospective measure of past stress experience in fishes as diverse as rainbow trout Oncorhynchus mykiss (Carbajal et al, 2019a), goldfish Carassius auratus (Carbajal et al, 2018; Laberge et al, 2019), Catalan chub Squalius laietanus (Carbajal et al, 2019b), sea bass Dicentrarchus labrax (Lebigre et al, 2022), and dab Limanda limanda (Vercauteren et al, 2022), where the focus has been on responses to aquaculture and environmental pollution. Individual fishes with relatively lower scale cortisol content would thus be assumed to have higher resilience to chronic stress than those with relatively high content.…”

Relationships of scale cortisol content suggests stress resilience in freshwater fish vulnerable to catch-and-release angling in recreational fisheries

The capture by angling of an individual fish is recognised as a short-term physiologically stressor. In fish populations exploited by catch and release angling (C&R), there is potential for some individual fishes to be captured on multiple occasions, but the longer term physiological consequences of this remain uncertain. Using scale cortisol content as a biomarker of chronic stress and scale samples from two fish populations exploited by C&R angling, we developed proxies of angling capture vulnerability before testing these proxies against scale cortisol content. In a riverine population of European barbel Barbus barbus, fish with the highest scale cortisol content were predicted as those sampled by angling rather than electric fishing, as angled fish had significantly smaller home ranges and diets based primarily on angling baits. In a population of common carp Cyprinus carpio in a small pond fishery, we predicted that fish with the highest scale cortisol content would be those with higher proportions of angling bait in their diet. In both species, however, the fish predicted to be most vulnerable to angling capture had the lowest levels of scale cortisol content. We suggest that this is through fish that are captured regularly being highly stress resilient (with this independent of other traits) or fish with traits that suggest high capture vulnerability being able to minimise their recapture rates through developing hook avoidance behaviours after an initial capture. Overall, these results suggest that scale cortisol content is a useful biomarker for measuring chronic stress from C&R angling.
