ABSTRACT. In Poland, live carp sold at retail are packed either in plastic bags without water or in containers or plastic bags filled with water. The aim of the study was to determine the impact plastic basket inserts in plastic bags without water used to pack live carp had on chosen physiological indicators of fish welfare. Drawing the plastic film away from the carp body through the use of the baskets limited negative changes in the indicators examined (hematocrit, glucose, lactate, and cortisol in the blood serum and muscle reaction), which indicate increased oxygen meatbolism and decreased stress from this type of packaging. Using basket inserts in plastic bags to pack carp sold at retail can improve their welfare.
