Abstract
A comparative study on the quality of shrimps landed in four fish landing centers
(Therespuram, Punnakayal, Tuticorin fishing harbour and Tharuvaikulam) of Tuticorin region
was investigated. The shrimps collected from the landing centers scored an overall sensory
score of > 7.0 out of 10.0. Most of the shrimps (80%) collected had TMA-N content more
than 5 mg%. TVB-N content of only 40% of the shrimps exceeded the limit of 30 mg%. Indole
was higher than 3.1|jg/100g in all the samples, but within 25 tig/100g. The total bacterial
load of 75% of shrimps were within the acceptable level of 105 cfu/g. Total and faecal coliforms
and E. coli counts of shrimps of Therespuram were quite high. Staphylococcus aureus counts
were high in shrimps of Punnakayal. Vibrio parahaemolyticus counts were almost similar in
all the samples. V. cholerae, Salmonellae and Listeria monocytogenes were absent in all the shrimp
samples examined. The shrimps landed in Tharuvaikulam had a better quality when compared
to the shrimps landed in the other three fish landing centers.
