Amélioration des techniques d'élevage de la chevrette Macrobrachium rosenbergii en Guyane ArchiMer
Griessinger, Jean-michel; Gondouin, Philippe; Dutto, Gilbert; Lacroix, Denis; Pollet, Thierry; Falguiere, Jean-claude; Mer, Gilles.
En 1987, l'analyse du système d'élevage en continu menée par l' IFREMER tant sur les fermes guyanaises que sur la station expérimentale de Kourou a permis de mettre en évidence les limites et les faiblesses de ce mode d'élevage. Elle a montré la nécessité d'un meilleur contrôle du cheptel depuis l'ensemencement jusqu'à la commercialisation afin de pouvoir atteindre de manière fiable des rendements de l'ordre de 2,5 T/ha/an.

Nictemeral variations for pacu Caranha, Piaractus mesopotamicus (Holmberg, 1887) culture in single - phase BABT
Barreto,Luiz Eduardo Guimarães de Sá; Igarashi,Marco Antonio; Hayashi,Carmino.
Studies related to nictemeral variation were executed in a fish growing pond, during all the seasons of the year, collecting data for dissolved oxygen; temperature; pH and electrical conductivity at the feeding channel on pond's surface, bottom and at streamlet bed. The results showed that Autumn was the season which had the lowest values of water temperature, the interval points, during Spring time, had superior average values of temperature when compared to the ones that were observed at external points. The lowest and highest index of pH were during Autumn season. The electrical conductivity didn't show significant differences during Autumn season. The samples obtained from the streamlet had very high significant differences with the samples of fish...
