Mahi-mahi Coryphaena hippurus is a promising species for aquaculture development and has been used as model oil toxicology physiology studies. This one of the fastest growth rates any marine teleost unique reproductive biology due to its high spawning frequency energy allocation. These characteristics lend being an excellent understanding broodstock nutrition other energetic pelagic species. In this study, egg morphometrics larval survival were tracked over 10-week period from initial capture wild mahi-mahi broodstock. Larval quality subsequent spawns collected time was quantified using activity indices (SAIs) metric assess quality. SAIs maintained did not significantly decrease (p < .05) course study. A multiple linear regression based on elapsed in captivity broodstock, diameter SAI at 1 dph provided most accurate prediction 3 (R2 = 0.996 p .05). There strong positive correlations with key nutrients: eicosapentaenoic acid (C20: 5n-3, EPA) related fatty ratios, vitamin E nearly all amino acids under investigation. study demonstrated that supply these nutrients diet.
