“…The vocalizations of animals are relatively easy to record (Dawkins, 1998 (Crowell and Comuzzie, 1993;White et al, 1993;Krishnamurthy, 1994;Mulligan et al, 1994;Schapiro and Bloomsmith, 1994;Warris et al, 1994;Schwartzkopf-Genswein et al, 1997;Grandin, 1998;Ruiz-Miranda et al, 1998;Weary et al, 1998;Zimmerman and Koene, 1998;Taylor and Weary, 2000;Zimmerman et al, 2000Zimmerman et al, , 2003Schön et al, 2004;McCowan and Rommeck, 2006). Yet, the potential use of this method as a measure of wellbeing in captive dolphins is still limited (Castellote and Fossa, 2006;Akiyama and Ohta, 2007;Therrien et al, 2012).…”

This study examines whether a group of captive false killer whales ( Pseudorca crassidens ) showed variations in the vocal rate around feeding times. The high level of motivation to express appetitive behaviors in captive animals may lead them to respond with changes of the behavioral activities during the time prior to food deliveries which are referred to as food anticipatory activity. False killer whales at Qingdao Polar Ocean World (Qingdao, China) showed signifi cant variations of the rates of both the total sounds and sound classes (whistles, clicks, and burst pulses) around feedings. Precisely, from the Transition interval that recorded the lowest vocalization rate (3.40 s/m/d), the whales increased their acoustic emissions upon trainers' arrival (13.08 s/m/d). The high rate was maintained or intensifi ed throughout the food delivery (25.12 s/m/d), and then reduced immediately after the animals were fed (9.91 s/m/d). These changes in the false killer whales sound production rates around feeding times supports the hypothesis of the presence of a food anticipatory vocal activity. Although sound rates may not give detailed information regarding referential aspects of the animal communication it might still shed light about the arousal levels of the individuals during diff erent social or environmental conditions. Further experiments should be performed to assess if variations of the time of feeding routines may aff ect the vocal activity of cetaceans in captivity as well as their welfare.

“…Where standard observations could not be made, subjective assessments of animal welfare were used and found to correlate well with objective assessments (for example for evaluating stress in food animals from stress-related vocalisations) (Warriss et al 1994). We felt that our dual approach using both objective and subjective assessments (both of which involved objective evaluation) reasonably represents conditions and issues of animal welfare at the CTF.…”

Various captivity-related health problems have been described as arising in the farming of sea turtles at the Cayman Turtle Farm (CTF). Our study included a desktop review of turtle farming, direct onsite inspection at the CTF, assessment of visual materials and reports provided by investigators from the World Society for the Protection of Animals (WSPA), and a limited analysis of water quality for potential pathogens. In particular, we assessed physical and behavioural condition of animals for signs of stress, injury and disease. During the onsite inspection we identified three distinct signs of physical injury and disease, six distinct signs of abnormal and problematic arousal-and discomfort-related behaviour; and three distinct signs of normal quiescence-and comfort-related behaviour. On evaluation of evidence provided by the WSPA we identified ten distinct signs of physical injury and disease, and managementor genetic-related conditions; six distinct signs of abnormal and problematic arousaland discomfort-related behaviour; and three distinct signs of normal quiescence-and comfort-related behaviour. We conclude that sea turtles at the CTF manifested important physical and behavioural signs that are indicative of problematic management and captivity-related stress, and the limitations of sea turtle adaptive plasticity in captivity. The problematic physical and behavioural signs, in our view, related to the inherent nature of intensive turtle propagation which in particular involves overt-and cryptoovercrowding and understimulating environments, and an associated failure to meet all the physical, biological and innate behavioural needs of sea turtles.

“…It is also due to dysfunctions of the pituitary, adrenal and thyroid glands (Hartung, 2003). Regrouped pigs showed elevated cortisol and CPK levels, and evidence of muscle glycogen depletion, indicating that fighting is a stressful experience (Warriss, 1994).…”
