Abstract: The aim of this
study is to observe the biological aspects such as length, weight,length weight
correlation and sex ratio. The study was done in October 2006.There were 199
females rays and 166 males rays on the observation, thus theywere measured as
length and weight. Therefore, it intended to achieve the weightlength
connection of those rays. The result of the observation was that the value
ofmales b and females was not differ obviously by 3 or b = 3. It showed that
thegrowth figure of male and female's Himantura gerrardi was isometric,
whichmeans that the growing of the length was balanced from the growing of
theweight. The sex ratio between males and females is 1:1.2. After testing of
Test X2,it had been found that there were not significant differences between
male andfemale. It also emphasized that the capture had been done for the
observation wason the breeding season, thus the males and females were altogether.
