Electron microscopical examination of gas gland cells of the physostome European eel (Anguilla anguilla) and of the physoclist perch (Perca fluviatilis) revealed the presence of significant numbers of lamellar bodies, which are known to be involved in surfactant secretion. In the perch, in which the gas gland is a compact structure and gas gland cells are connected to the swim bladder lumen via...

Survival, growth, and food intake of Eurasian perch (Perca fluviatilis) juveniles from different stocks originating from various geographic regions of Europe were compared under the same conditions of laboratory-scale intensive culture. In Experiment 1, four stocks originating from Italy (I), southwest (SF) and northwest (NF) France, and Belgium (B) were examined at larval and early juvenile (i...

RESUMO Reconstituímos o problema da gênese em sua dimensão mais fundamental na fenomenologia temporalidade. Em seguida, mostramos que condições ele pode ser recolocado a partir de uma do movimento e, finalmente, dispensado numa diferença vias elaboração. Trata-se um encaminhamento para logos fenomenológico: medida reformulado sem que, com isso, se perca consistência fenomenalidade.
