Fatty acid composition in a cultured marine harpacticoid, Amphiascoides neglectus
Lipid content especially fatty acids are used by animals for their growth, reproduction and neural development particularly in zooplankton and fish. Thus, it is important to produce live feed copepods with reasonable fatty acids content for aquaculture use. This information and technique is pla...

| description |
Lipid content especially fatty acids are used by
animals for their growth, reproduction and neural
development particularly in zooplankton and fish.
Thus, it is important to produce live feed copepods
with reasonable fatty acids content for aquaculture
use. This information and technique is planned to be
transferred to the industrial partner, Flexible Tech
Sdn. Bhd. In this study, salinity has been used as
independent variable to culture harpacticoid copepod
(Amphiascoides neglectus) in the open hatchery
under ambient temperature for four months. The
culture was done with 5 replicates in 250ml glass
container at 30ppt and 20ppt. At the end of the
experiment, fatty acid compositions of harpacticoid
copepods were determined using GC-MS for both
salinities. From the result, harpacticoid copepods
cultured under salinity 30ppt showed more fatty acids
variety than salinity 20ppt. It is shown also to have
higher total fatty acid number compared to salinity
20ppt (30 and 15 fatty acids respectively). The
existence of EPA (eicosapentaenoic acid) which is an
essential fatty acid (EFA) was detected in salinity
30ppt even though with very low concentration
(0.01±0.02). Salinity 30ppt is a favorable salinity
treatment to be used in copepods culture in order to
get EPA existence while considering other
parameters such as temperature, pH and diet used.
Graduate Interns (GI) were trained to impart the
technique to culture high fatty acid copepods by
maintaining the salinity at 30ppt.This information
was then use for marketing purpose of the product. |
