Summary: | The Lake Extremoz is one of the three big lakes in the State of Rio Grande do Norte. The present work was carried out in this lake during the period of October 2000 to September 2001, which included the dry and the rainy seasons. Parauchenipterus galeatus Linnaeus, 1766 represent 10% of the commercially important species captured from this lake. Fish samples were collected on a monthly basis, besides registering the rainfall, temperature, and dissolved oxygen of the lake. The populational structure of cangati and the stage of maturation of the gonads were determined, besides the gonadosomatic relation. The results indicate that the study population presented higher mean values of total length and weight during the dry season. Mature fishes were caught during the months of May, June and July which represented the reproductive season. |
