As part of a study of the possibility of using the urchin T. gratilla to
control the growth of macroscopic algae on shallow reefs in Kaneohe Bay,
we examined the growth rate of this urchin. We measured growth of tagged
(PIT tagged) urchins at both sites where they were abundant (Sampan Channel
site, Reef 13 and Reef 11) and at sites to which we introduced them
(Coconut Island reef flat, Reef 22, Reef 29, Reef 19).
Purpose:
Control the growth of macroscopic algae on shallow reefs in Kaneohe Bay.

As part of a study of the possibility of using the urchin T. gratilla
to control the growth of macroscopic algae on shallow reefs in Kaneohe Bay,
we examined the growth rate of this urchin. We measured growth of tagged
(PIT tagged) urchins at both sites where they were abundant (Sampan Channel
site, Reef 13 and Reef 11) and at sites to which we introduced them (Coconut
Island reef flat, Reef 22, Reef 29, Reef 19). Reef 22 is miss-numbered as
Reef 21 on Roy's (1970) map of the reefs of Kaneohe Bay (referenced on file).
The incorrect number is used in this data file.
Growth was assessed by measuring change in diameter of the test over part
of a year. Three diameter measurements were made on each urchin with a
pair of steel calipers (tips of plastic calipers rapidly wore down). Error
in these measurements occurred because some urchins are asymmetrical and
because spines interfered with closure of the caliper jaws.
