Fatty acids (FAs) were determined in homogenates of pleons and cephalothoraxes from all ovigerous females (COFs and TOFs) of a replicate and in homogenates of COF eggs using gas chromatography (GC) after FA transesterification to fatty acid methyl esters (FAMEs).
The biochemical composition and energy content of female pleons and cephalothoraxes were analyzed with two-way ANOVA.
On the other hand, female cephalothoraxes had a significantly higher ([F.sub.1,30] = 3.98.
Nineteen female juvenile Chinese shrimps (body length: 6.0 [+ or -] 0.5 cm and body weight: 3.0 [+ or -] 0.2 g) and 20 male juvenile Chinese shrimps (body length: 6.4 [+ or -] 0.5 cm and body weight: 3.7 [+ or -] 0.2 g) at stage PL75 (75 days after metamorphosis to postlarvae, when the external sex phenotype began to appear) were collected and their cephalothoraxes were dissected and preserved in liquid nitrogen individually for RNA extraction in order to be used for sex markers' screening.
Total RNA extraction and cDNA synthesis for the cephalothoraxes of female or male grow-up stage shrimp and each juvenile shrimp were performed as described previously.
