Notes:
Catfish (Tachysurus spp.) from marine water, tilapia (Tilapia mossambica, Peter) from brackish water, and Mrigal (Cirrhina mrigala, Hamilton) from fresh water were studied for biochemical changes during rigor mortis. The pH was respectively 6.7, 6.6, and 6.8 in the freshly killed fish, decreased after death, and rose again with the resolution of the rigor. Glycogen contents immediately after death were 320, 369, and 453 mg per 100 g of fish muscle, and, decreased rapidly during the first few hours of the experiment. The contents and the rate of decrease of phosphorus of creatine phosphate and ATP were greatest in the catfish. Phosphorus of creatine phosphate decreased faster than that of ATP. Lactic acid content increased rapidly in the beginning and then gradually until the rigor was resolved.
