Abstract Assessment of quality of fish and shrimps landed at the Fish Harbour, Cochin was
made over the period January, 1980 to December, 1982. A total of 201 samples were
analysed. Nearly 75% of the samples scored between 6-10 in a 10 point hedonic scale
and the percentage unacceptability based on sensory assessment was 5. 5%. In 10.1%
of the samples, total volatile nitrogen was >30 mg% and in 8.3% of the samples trimethylamine-nitrogen was > 10 mg%. Both, the gr Torrymeter and Intellectron Fish
Tester VI readings marked significant correlation with sensory scores and chemical
indices; but failed to bear any significant correlation with bacterial counts. Of the
5-1 total samples 66.7% had total plate count (TPC) 210 g and 8. 5% were considered
unacceptable based on TPC >5 x 105g-1; 63.2~~ of the samples were free from
Escherichia coli; 26.4 ~;.; had > 20 E. coli g ~ 1 and 20.4% of the samples contained faecal streptococci > 10 s g-I. Seven percent of the samples showed coagulase positive
staphylococci > 100 g- I . Salmonella could not be detected in any of the samples ยท
examined. Crushed ice samples and the platform of the harbour had high bacterial
loads.
