Overview of liquid-liquid extraction and UHPLC-HRMS/MS analysis of eicosanoids and PUFAs in the <i>P</i>. <i>monodon</i> male reproductive tract.

(A) Male P. monodon broodstocks were dissected to obtain testes (TT) and vas deferens (VD). (B) Sample preparation included tissue homogenization, pH adjustment, addition of antioxidant (10% BHT), and addition of internal standards. (C) Testis homogenates were subjected to ethyl acetate extraction (upper panel) whereas vas deferens homogenates were subjected to methanol-chloroform extraction (lower panel). (D) Tissue extracts were analyzed using the UHPLC system. Eicosanoids and PUFAs were then identified using HRMS/MS. (E) Metabolite quantification and data analysis were performed to determine levels of eicosanoids and PUFAs in each organ. LN2 and ACN were abbreviated for liquid nitrogen and acetonitrile, respectively.</p

Total sperm counts and percentage of sperm abnormality in domesticated shrimp fed with polychaetes and feed pellets.

Spermatophores of domesticated shrimp fed with either polychaetes (black bar, N = 8) or commercial feed pellets (gray bar, N = 8) were used in the analysis to determine (A) total sperm counts and (B) percentage of sperm abnormality. Error bars represent standard deviations. Asterisks indicate a significant difference between samples using the t-test (** for P < 0.01).</p

Comparative analysis of eicosanoid and PUFA levels in testes and vas deferens of eleven-month-old, domesticated shrimp fed with polychaetes or feed pellets.

Levels of (A) PGE2, (B) PGF2α, (C) 15d-PGJ2, (D) (±)8-HETE, (E) (±)11-HETE, (F) 12(R)-HETE, (G) (±)12-HEPE, (H) (±)18-HEPE, (I) ARA, (J) DHA, and (K) EPA were compared between polychaete- (black bar, N = 5) and pellet-fed shrimp (gray bar, N = 5). Error bars represent standard deviations. Asterisks indicate statistically significant differences in metabolic levels between polychaete- and pellet-fed shrimp using the t-test (* for P P t-test († for P P t-test (# for P P < 0.01). ND means that the designated metabolite was not detected.</p
