Abstract

Portable Incubator use (NUPI 12) in Embryogenesis silver Sardinha , lycengraulis grossidens (spix & agassiz , 1829 ), and of the Armored Cascudo viola , Loricariichthys platymetopon (isbrücker & nijssen , 1979) , in Uruguay River Basin east, Uruguaiana , RS. The research was conducted in the city of Uruguaiana , RS , in the Uruguay River basin , from September 2012 to October 2014. Was made an incubator in order to maintain the water quality standards in the process of the embryogenesis the L.grossidens and L. platymetopon. The research was divided into three stages , the first being the making of the incubator , the second checked the incubator in maintaining the quality of water without addition of biological material (oocytes and eggs) and the third , tested the incubator effectiveness in embryonic development oocyte by sardinha prata and cascudo viola . It can be concluded that the incubator NUPI 12 V, keeps the water quality standards, when used with circulation and recirculation , and also provides favorable conditions for the development L. platymetopon the husk and L. grossidens.
