The daily food intake of seahorse was determined with the following treatments: T1-Artemia; T2-mysid; T3-Acetes; T4-Artemia+mysid; T5-Artemia+Acetes; T6-mysid+Acetes; and T7-Artemia+mysid+Acetes. Percent body weight (% BW) of daily food intake until satiation was similar in Artemia, mysid and Artemia+Acetes (20-22%), but significantly higher in mysid+Acetes, Artemia+mysid, and Artemia+mysid+Acetes with 25, 31 and 33%, respectively (p<0.05). Single diet of frozen Acetes was least consumed at 6%. Thus, mysid was the preferred food of adult seahorses as a single or combined diet with Artemia and Acetes. Diet treatments with single mysid or combined with Artemia and Acetes have significantly higher brood size (223-292) than the other treatments (107-152) (p<0.05). Significantly longer parturition interval (60days) was observed in seahorses fed with Artemia than those fed with mysid or in combination with other natural food (13-26days), but not significantly different to seahorses fed with Acetes and Artemia+Acetes (42-45days). Parturition occurrence in seahorse fed with Artemia, Acetes and Artemia+Acetes (2.7-4.3) were the lowest, while Artemia+mysid and Artemia+mysid+Acetes have significantly higher occurrence followed by mysids+Acetes and mysid only (p<0.05). Thus, the reproductive performance was improved when seahorses were fed with single or combined foods including mysid. Total lipid was positively correlated to brood size and parturition occurrence, while DHA:EPA ratio was negatively correlated to brood size and parturition occurrence.
