Results suggest that worms from farmed aquaculture, high nutritional composition and unsaturated fatty acid content used marine shrimp broodstock maturation. The female white leg shrimps fed worms from farmed aquaculture showed absolute fecundity 2% higher (28.34 × 104 compared to 27.79 × 104), actual fecundity higher 2% (16.67 × 104 so với 15.93 × 104), fertization rate higher 1.5% (85.87% so với 84.53%) and hatching rate higher 2% (88.94% so với 87.22%) compared to broodstock fed worms from wild. Metamorphorsis rate form Nauplii to Zoea 1 was higher (p<0.05). Sperm quality of male white leg shrimps showed better as they were fed worms from farmed aquaculture.
