Abstract:

Arteries of rainbow trout, Salmo gairdneri, were severed at the isthmus, nape, and caudal peduncle, and blood loss was measured.  The greatest amount of bleeding occurred with the caudal penduncle cut, resulting in a loss of blood weighing 2.29 percent of the total body weight.  The effects of delayed bleeding and the use of an anticoagulant, also studied, were of no benefit.  The quality of flesh, after being frozen up to 8 months, was superior for bled fish as evaluated by appearance, odor, and lipid stability.
