“…Once a salamander has been released, SVL cannot be measured again, so unnoticed errors that occurred while measuring will become part of the dataset (Brown et al., 2018). Furthermore, prolonged handling stress produces negative effects on animal health (Allen‐Blevins et al., 2017; Bliley & Woodley, 2012; Caipang et al., 2014; Lunghi et al., 2016). Therefore, photographing salamanders and the post hoc measurement of SVL e facilitates easier measurements, requires shorter handling time with images of sufficient quality (Bradley, 2018; Lunghi et al., 2020), and is a method available to a wide number of operators (Margenau et al., 2018; Miyazaki et al., 2014).…”

“…Handling wild animals does not only facilitate transfer of pathogens (Garner et al., 2006; Martel et al., 2014) but induces stress, provoking a cascade of negative effects on their immune system (Caipang, Fatira, Lazado, & Pavlidis, 2014), microbiome (Allen‐Blevins, You, Hinde, & Sela, 2017), and behavior (Bliley & Woodley, 2012). Amphibians are particularly susceptible to handling, and even short manipulations using gloves may strongly alter their internal temperature (Lunghi et al., 2016).…”

The worldwide biodiversity crisis with the resulting need to increase species protection has led researchers to pursue and select survey methods that guarantee the best quality of data and produce the least negative effects on wild animals. Plethodontids are the most diverse family of salamanders; all species are very sensitive to human handling and noninvasive, but accurate, measurement methods are needed to reduce researchers’ impact. Here, we tested the reliability of a noninvasive post hoc method in estimating the snout–vent length (SVL) from photographs showing salamanders’ dorsal view. The correlation between the estimated snout–vent length (SVL e ) and the conventional SVL was high ( R 2 m = .81), and no significant difference occurred between operators with different experience. Finally, we list the numerous advantages for the use of SVL e in terms of data quality and in reducing the stress caused to wild animals.

Aeromonad infections continue to affect the fish farming industry. Several new species of Aeromonads in freshwater ornamental fish have been identified in the last years. In this study, we have characterized an Aeromonas veronii isolate from a diseased guppy. The series of experiments identified the intrinsic and extrinsic factors contributing to the pathogenic characteristics of the isolate. It has been shown to be pathogenic to both guppy and zebrafish. The results offer foundational knowledge in the development of preventive and therapeutic measures to combat this pathogen in the ornamental fish industry.

“…For example, cortisol is commonly measured as an indicator of hypothalamic–pituitary–interrenal axis (HPI) activity because it is a fundamental part of the primary stress response, occurs rapidly with acute stress and is correlated with disease susceptibility, unusual behaviour and impaired cognitive performance 30,34,137 . Blood sampling is a common technique for measuring cortisol in fish 137 ; however, cortisol elevations may occur from the collection process itself, for example removal from the water, handling and needle puncture 42,50,138–140 . Other physiological measures can have similar disadvantages; therefore, there is a need for sampling methods that deliver robust results but are practical and aligned with good welfare practices.…”

As aquaculture continues to grow and intensify, there is an increasing public concern over the welfare of farmed fish. Stress and production‐related pathologies and repressed growth are examples of the challenges facing aquaculture, and their impacts could be minimised by effective identification of the early signs of impaired welfare. Many welfare monitoring methods have been recommended; however, continuous and reliable welfare monitoring in aquaculture is not yet widespread and commonplace. The aim of this scoping review was to present an overview of the most recent developments in fish welfare assessments with a specific focus on practical translation to the aquaculture industry. A keyword‐based search was undertaken to identify peer‐reviewed papers published between 2014 and 2020 in which a novel method with the potential to be used for the assessment of fish welfare in aquaculture was introduced. The results were sorted into two categories: non‐invasive and invasive methods. All methods were assessed for their advantages and disadvantages, potential applicability to aquaculture. Invasive methods were also ranked on their degree of impact. It is concluded that increased interest into fish welfare, in combination with more intelligent modern technology, has resulted in the development of newer and more refined alternatives to traditional methods of welfare assessment such as behaviour monitoring by 2D cameras and plasma cortisol evaluation. Although, in many cases, more research is needed before these methods are suitable for widespread industry use, studies that focus on increasing the precision, automation and practical applicability of these methods are a promising avenue for future research.
