The physiological stress response of the Atlantic stingray ( Hypanus sabinus ) to aerial exposure

Physiological and immunological responses of sea cucumber Apostichopus japonicus during desiccation and subsequent resubmersion

“…Previous studies have demonstrated that organisms could eliminate the metabolites in tissue and alleviate stress response after a period of recovery (Oliveira, Rossi & Da Silva, 2001; Duan et al, 2016a). Lambert et al. (2018) also found that whereas the reduction in plasma glucose content of Atlantic stingray Hypanus sabinus following air exposure gently recovered to a relatively higher level after recovery in water, the increase in blood lactate concentration was slower to dissipate.…”

“…The effect of desiccation on osmolality of sea cucumber was in accordance with the commonly observed osmotic fluxes in other stressed fishes (Trushenski et al, 2010). This prolonged imbalance of cortisol and osmolality at D6 treatment demonstrated that desiccation has long-term negative effects, maybe requiring extensive recovery (Lambert et al, 2018).…”

“…During the acclimation period, the sea cucumbers were fed with a formulated diet (fish meal, soybean meal and Sargassum thunbergii used as protein sources and squid liver oil as lipid source, containing 16.80% crude protein, 2.30% crude lipid and 10.23 kJ g −1 energy) and up to 5% of their total biomass per day. In order to avoid the changes in physiological status as a result of food intake, all animals were fasted for 3 days prior to the start of the experiment, and were also not fed throughout the period of desiccation and subsequent resubmersion (Trushenski et al, 2010; Lambert et al, 2018). After acclimation, the sea cucumbers were divided into two groups, i.e., control group and desiccation group.…”

“…In aquaculture practice, sea cucumbers usually suffer from desiccation during transportation without water. Desiccation is a common stressor experienced by aquatic animals (Lambert et al, 2018); however, desiccation tolerances are known to be discrepancy among species (Wells & Baldwin, 1995).…”

Effects of biological traits on capture‐induced parturition in a freshwater stingray and perspectives for species management

“…conservation, fisheries management, fishing stress, premature birth, upper rio Paraná, viviparity 1 | INTRODUCTION Elasmobranchs (sharks, rays and skates) share a number of life-history traits, such as low reproductive output and slow growth, which make them particularly sensitive to overexploitation and population depletion/collapse (Dulvy et al, 2014;Stevens et al, 2000). As a result, numerous studies have explored how fisheries interactions negatively affect the survival and fitness of elasmobranchs (e.g., Lambert et al, 2018;Skomal & Mandelman, 2012). For example, studies have been performed to assess species that are more vulnerable to capture stress and mortality (Gallagher et al, 2014;Mandelman & Skomal, 2009), to understand the variation in the stress response over ontogeny (Prohaska et al, 2018) and to unravel the occurrence of sublethal effects on important biological processes such as growth and reproduction (Guida et al, 2017).…”
