Physiological stress in striped bass: effect of acclimation temperature

Physiological Responses to Three Different Levels of Vibration Stress in Catfish, Silurus asotus

“…Their level decreases when animals are in a healthy status, while it increases when they get sick or there necroses occurs in their tissues (Almeida et al 2002). Davis and Parker (1990) reported that hemodynamic indices for oxygen carrying ability increased with an increase in stress. In this study, the level of plasma AST and ALT at day 0 was significantly different from the corresponding one at the end of tests.…”

“…This indicates that vibration inflicted on catfish (this study was involved with) might have given significant physiological loads to their liver and other tissues. Davis and Parker (1990) reported that hematological indices for oxygen transmission ability increased when stress was present. The level of hematocrit, RBC and hemoglobin in blood samples is among basic blood factors through which oxygen transformation ability can be estimated.…”

Morphometric relationships of African big barb, Labeobarbus intermedius (Rppell, 1836) in Lake Koka, Ethiopia

“…time of the year, location, catchability, quotas) decide the catch volume and size distribution of the catch (Mous et al, 2004). Environmental factors, such as water temperature (Davis and Parker, 1990) and water salinity (Barton and Zitzow, 1995;Mous et al, 2004) also influence the size of fish catch. The result obtained for LWR showed that the fish has not obeyed the cube law of Bagenal and Tesch (1978), which assumes the regression slope (b) to be three or almost three.…”

Evaluation of Juvenile Fall Chinook Salmon Stranding on the Hanford Reach of the Columbia River, 1999 Annual Report.

“…Except for hsp70 expression, which we will discuss below, the other factors we assessed (plasma cortisol, glucose, and lactate) all increased during the thermal warming, reached maximal values at the time of maximal temperature, and returned to levels similar to initial values by 24 h. Some studies have reported similar responses in other species exposed to thermal stress. For example, hypercortisolemia or hyperglycemia (or both) have been shown in cutthroat trout (O. clarki), steelhead (O. mykiss), coho salmon (O. kisutch), and Tilapia aurea exposed to acute temperature shocks (Wedemeyer 1973;Strange et al 1977;Kindle and Whitmore 1986), in coho salmon exposed to a fluctuating temperature regime of 6.5-20°C (Thomas et al 1986), and in Tilapia aurea and striped bass (Morone saxitalis) acclimated to temperatures outside their preferred range (Kindle and Whitmore 1986;Davis and Parker 1990). In contrast, some of the same or other studies have shown little or no response of plasma cortisol and glucose in fish to temperature stressors (e.g., Strange et al 1977;Carmichael et al 1984;Thomas et al 1986).…”
