Adaptação Metodológica Para Estudos De Organismos Zooplanctônicos"In Situ", Aplicados À Piscicultura

Abstract

Zooplanktonic organisms play an important role in the feeding of fish larvae, both in nature, and in artificial fish ponds. With the mass culture of zooplankton, the knowledge of important items of the organisms life cycle under different circumstances, can determine the success of the culture. This work shows an adaptation of commercial nursing bottles used in zc \'plankton studies that permits regular investigation of life cycle experiments of zooplanktonic ;rustaceans (Cladocera) in different environments such as: laboratory (immersed in aquariums or not) and "in situ", in fish ponds, or natural environments.
