Captive reproduction, larviculture of Florida pompano

U.S. trials indicated wild-caught pampano could be feed trained and spawned in captivity via hormonal induction. Observations of fecundity, egg fertilization rates, and spawning frequency suggested that quan­tities of pompano seedstock could be produced over time. Although survival during test
