Morphometric Characteristic of White Shrimp Fenneropenaeus merguiensis de Man 1888 in South Sulawesi Indonesia

Morphometric studies are not only essential to understand the taxonomy but also characteristic of the population. The morphometric character was examine to detect variation of Fenneropenaeus merguiensis population in Pinrang, Siwa and Takalar South Sulawesi of Indonesia. The number of samples used were 50 shrimps for each location that consisted of 25 males and females, respectively. A total of 23 length character were evaluated by using electric digital calliper 0.01 mm and two characters by using analytic balance 0.001 mg. Measurement data were standardise with an allometric method to avoid the effect of size and age on morphometric traits and then analyse by discriminant analysis. The results showed the significance different of 25 morphometric characters between Pinrang, Siwa, and Takalar both of male and female. Based on difference on morphometric character further forming two population grup that is group I consist of Siwa and Takalar male and female, and male and female Pinrang formed group II
