This study is focused on the occurrence of salps and doliolids in the Southern South
China Sea .Sampling was done during pre-monsoon season on July 2018 that took 5
days at 17 stations by Research Vessels RV Discovery UMT covering Kelantan and
Terengganu waters. The sample was collected by bongo net that was hauled vertically
from 5 meter above the seafloor to the surface. Data physical was collected with towed
of CTD. Four types of salps was identified which Thalia sp, Thalia rhamboides, Pagea
sp, and Salpa maxima and there are four types of doliolids been identified which is
Dolioletta sp. Doliolina sp. Doliolum sp. and Dolioloides sp. The highest density
distribution of salps is Thalia rhamboides 11.385 ind/m 3 and for doliolids is Doliolina
sp. 21.037 ind/m 3 . The distribution of salps and doliolids are both in patchy and
random. Pinciple Component Analysis (PCA) found salps and doliolids influenced much
by the depth and temperature with a correlation eigenvalue 2.6 for temperature and
1.31 for depth.
