Gravid wild kutum broodstock, Rutilus frisii kutum, on their upstream migration to Valiabad River (northern Iran) were kept in captivity to allow them to ovulate (captive ripe). Then the impact of captivity on some reproductive and physiological parameters (i.e., plasma cortisol and glucose levels, fertilization percentage, gonadosomatic index and fecundity) were assessed and results were com...

There are significant differences among species in their ability to adapt to captivity. Some species breed well in captivity and usually show no apparent signs of poor welfare, while other highly similar species sometimes live only a short time, breed little or not at all and often show abnormal behaviours. Marine mammals provide several examples of these differences. Thus, the life expectancy ...

Although the transfer of wild animals to captivity is crucial for conservation purposes, this process is often challenging because some species or individuals do not adjust well to captive conditions. Chronic stress has been identified as a major concern for animals held on long-term captivity. Surprisingly, the first hours or days of captivity have been relatively overlooked. However, they are...

When wild animals are brought into captivity for the first time, they frequently develop chronic stress symptoms. Animals can develop glucocorticoid dysregulation or changes in the sympathetic nervous system over the course of the first week in captivity. By blocking the action of epinephrine and norepinephrine using α- or β-blockers, we hoped to reduce the degree of chronic stress symptoms exh...

BACKGROUND The psychological responses to captivity were measured in a sample of former prisoners of war (POWs) 18 and 30 years after release from captivity. METHOD 209 Israeli veterans of the 1973 Yom Kippur War (103 ex-POWs and 106 controls) who had taken part in a previous study conducted in 1991 participated in the current study conducted in 2003. The study assessed current rates of postt...
