DIETARY ZINC REQUIREMENT OF THE RED DRUM, SCIAENOPS-OCELLATUS Academic Article

abstract

• A feeding trial was conducted to determine the dietary zinc requirement of juvenile red drum, Sciaenops ocellatus, in brackish (6 ppt) water. Semipurified diets containing graded levels of zinc (5, 10, 20, 30 and 40 mg Zn/kg) were fed to juvenile red drum in triplicate aquaria for 8 weeks. Overt signs of zinc deficiency such as suppressed growth and increased mortality were observed within 3 weeks in fish fed the basal diet containing 5 mg Zn/kg. At the end of 8 weeks, scale- and bone-zinc concentrations of fish fed the various diets were significantly (P < 0.01) affected and increased linearly as dietary zinc increased until plateauing around 20 mg Zn/kg diet and greater. Based on these data, 20-25 mg Zn/kg of dry diet was determined to be the minimum dietary zinc requirement of red drum. 1991.
