Abstract
The authors followed trimetylamine (TMA) and Total Volatile Basis (TVB) evolution in some Brazilian fishes during ice storage at 4 degrees C for 15 days. The fishes studied were: Micropogon furniere, Umbrina canosai, Centropomus undecimalis, Cysnoscion acoupa; samples were taken and analyzed each 48 h. Each species was stored eviscerated (E) or not-eviscerated (NE) in order to estabilish a possible advantage of on board evisceration. The results showed a log. relation between TVB or TMA percentage in the fish tissues and the days of storage; Mathematical models were established for predicting "storage life" for each fish out the basis of its amine content. Evisceration, immediatly after capture retarded deterioration and seem to be a useful practice.
