Growth rate and mortalities of tagged and untagged shrimps among six tanks, each 300 l consists of
30 untagged shrimps and 30 tagged shrimps were studied in two stations Bandargah and Delvar
during 4 months from February to June 2012. Weights of 10 specimens were randomly measured.
The mortality of two groups was evaluated by counting of remained shrimps of which the average
of survival rate was 52.0% for tagged and 44.5% for untagged shrimps in Bandargah. The mortality
rates among the Control and tagged group were 63 and 59%. The mortality for the examined groups
was significantly different between two stations suggesting that management and environmental
conditions were the most influencing factors on the mortality rates. The results of ANOVA showed
no significant difference in the weight growth of tagged and control groups. The results of the
present study showed that the injected elastomer tags did not effect on growth and mortality rates.
