Summary

THIS INVESTIGATION HAS DETERMINED THE SPOILAGE PATTERN AND ICED-STORAGE LIFE OF SPINY DOGFISH AND SHOWS HOW ITS STORAGE LIFE MIGHT BE AFFECTED BY SUCH HANDLING PRACTICES AS GUTTING AND/OR BLEEDING THE FISH IMMEDIATELY FOLLOWING REMOVAL FROM THE WATER OR HOLDING THESE FISH AT OTHER THAN THE IDEAL ICED TEMPERATURE. WELL-ICED DOGFISH HAVE A SHELF LIFE OF ABOUT 11-12 DAYS. IF GUTTED IMMEDIATELY, THE SHELF LIFE CAN BE EXTENDED ABOUT 4 DAYS. DESPITE THEIR HIGH UREA CONTENT, AMMONIA FORMATION DOES NOT SEEM TO BE A PROBLEM IN WELL-ICED DOGFISH. AT 281 AND 286.9 K (8 AND 13.9 DEG C), AMMONIA FORMATION IS MUCH MORE RAPID AND DRASTICALLY SHORTENS THE SPECIES SHELF LIFE.
