Pikeperch larviculture ( <i>Sander lucioperca</i> [L., 1758]) with <i>Brachionus plicatilis</i> (Mueller, 1786) (Rotifera) and <i>Apocyclops panamensis</i> (Marsh, 1913) (Copepoda)

The effect of live feed diets containing Brachionus plicatilis (B) and Apocyclops panamensis (A) was investigated on pikeperch larval survival, growth, fatty acid composition in two experiments (E1 E2). Up to six different were provided the larvae, which letters diet names represent organisms as mentioned above subsequent number per larva day. In E1, start cultures with 35 larvae/L supplied (B200 B100 + A100) 7 days until 10 post hatch (dph). E2, 50 fed diets, B280 A120, B340 A60, B400, B420 A180, B510 A90, B600. highest survival specific growth rates (SGR) occurred B200 (E1). A60 performed best. A trend increasing found E1 from 68.9% (B100 71.6% E2 64.0% (B280 A120) 93.7% (B340 A60). Larval SGR tended increase higher shares dietary B. both experiments. polyunsaturated acid, linoleic (LA), followed same pattern a plateau reached, indirectly indicating feeding threshold. LA seemed play an important role this period. Consequently, should contain at least 340 ind. larva−1 day−1 6.3 milliliter dph improve larviculture.
