FREEZING CHARACTERISTICS OF TROPICAL FISHES II.TILAPIA (Tilapia mosambica)

Abstract

Tilapia from fresh water and brackish water-sources behaved
differently during iced and frozen storage. The former showed
an ice storage shelf life of about 13 days while the latter
showed signs of spoilage beyond 10 days. In their respective
freezing characteristics, the samples from the two sources exhibited
far more significant variations. The fresh water type iced for
13 days preserved well for over 24 weeks when frozen and kept
at a temperature of -18° C, while the brackish water variety held
in ice for lO days and subsequently frozen gave a shelf life of
only 8 weeks under similar conditions.
