Abstract
The effect of prolonged cold storage on muscle adenosine triphosphatase(ATPase) and lactate dehydrogenase (LDH) activities was
studied in a variety of fresh water and brackish water fish. Decreasein enzyme activity was observed in all samples stored frozen (- 20°C)over a period of 180 days. Highly significant negative correlation was
observed between enzyme activity and frozen storage period with mullet,pearlspot, milk fish and tilapia. Significant linear correlations wereobserved between decrease in enzyme activities and other biochemical
indices and sensory scores. The results indicated that loss of activities of ATPase and LDH in fish muscle was significantly related to earlychanges in quality of frozen stored fish.
