Description
  • Vliv zelené vody a intenzity světla na vnější úroveň stravy, přežití, růst, lipidů a mastných kyselin byl zkoumán u larev tresky v experimentu s dvojím opakováním. V každém experimentu byl šest nádrží vystaveno %22nízké%22 dávce záření (12-20 mu W cm(-2)) a dalších šest nádrží %22vysoké%22 dávce záření (240-283 mu W cm(-2)). Vždy do třech nádrží s různou dávkou záření byla přidána řasa Isochrysis galgána pro vytvoření zbarvení zelené vody a v ostatních třech nádrží byla vždy čistá voda. Larvy tresky byly nasazeny do nádrží ve stáří 3 dnů po vylíhnutí a krmeny vířníkem B. plicatilis. Přežití larev a naplněnost střev při zahájení podávaní krmení se zlepšilo při použití zelené vody, příjem krmiva nebyl ovšem signifikantně ovlivněna experimentálním ošetřením. Na druhé straně nízká intenzita záření způsobila okrajové zvýšení schopnosti příjmu krmiva. (cs)
  • The effects of green water and light intensity on establishment of exogenous feeding, survival, growth, and lipid and fatty acid composition were investigated for larvae of Atlantic cod in two replicate experiments. In each experiment, six tanks received %22low%22 irradiance (12-20 mu W cm(-2)) and another six tanks %22high%22 irradiance (240-283 mu W cm(-2)). In three of the tanks within each light treatment, the alga Isochrysis galbana was added to make green water, and the other three tanks had clear water. Cod larvae were stocked into the tanks at day 3 post-hatch, and fed the rotifer B. plicatilis. Larval survival and gut filling at initiation of exogenous feeding were significantly improved by use of green water, feeding incidence was not significantly affected by any of the treatments, although low light conditions gave a marginal increase in feeding incidence.
