Three experiments were conducted to evaluate the effects of micro‐bound diets ( MBD ) on southern flounder larvae. In experiment 1, four MBD s were formulated with different protein sources as follows: MBD 1: herring meal, MBD 2: menhaden meal, MBD 3: menhaden and squid meal; MBD 4: menhaden, squid and herring meal. In experiment 2, four MBD s were formulated as follows: MBD 5: menhaden, squid and herring meal; MBD 6: menhaden, squid, herring and attractants; MBD 7: menhaden, squid, herring and casein, and MBD 8: menhaden, squid, herring, casein and attractants. In experiment 3, three groups were maintained as follows: Group 1: live feed; Group 2: co‐fed with MBD 6; and Group 3: MBD 6. In experiment 1 on 35 dph, survival and body weight ( BW ) of the fish fed MBD 4 was significantly higher than the MBD s 1 and 2. In experiment 2 on 34 dph, fish fed MBD 6 had significantly higher BW than the commercial microdiets. In experiment 3 on 21 dph, fish receiving only MBD had significantly lower survival than the other groups. Growth, survival and larval fatty acid composition suggested that co‐feeding MBD 6, a mixture of marine protein sources plus attractants was more effective than the other MBD s.
