Suitability of Different Live Feed for First Feeding of Freshwater Fish Larvae

First feeding of many fish larvae depends on live feed. A comparative investigation the effectiveness different types feed is not available to our knowledge. Hence, we conducted a study examine effect and combinations performance (survival rate, total length, body width, mass, malformation rate) pikeperch, Sander lucioperca, larvae. From day 0 (onset exogenous feeding) 10, saltwater rotifer Brachionus plicatilis, freshwater calyciflorus, ciliate Paramecium bursaria, copepods (nauplii copepodites) from lake population, Artemia nauplii were tested. Feeding with B. P. bursaria resulted in high survival rates 80% homogenous significant growth (increase length 50% width 20%). As follow-up feed, copepod tested 11 20. Copepod superior nauplii, as fed showed higher (67–70% versus 38–47%) more homogeneous growth. switch seawater or vice versa decreased rates. Therefore, regime consisting calyciflorus followed by considered optimal first pikeperch. The rate was affected regimes. To investigate wider applicability transferability these findings, complementary investigations performed burbot, Lota lota, whitefish Coregonus atterensis. regimes used for S. lucioperca also suitable lota. Moreover, L. lota could be onset feeding. For C. atterensis, initial had no positive effects. considering are very species specific should established each new species.
