【 摘 要 】

The purpose of the study was to determine the density and pattern of growth of white shrimp (Penaeus merguiensis)of the village Nipah waters. The data collection was conducted by sampling using nets and fishing gear "Langge" (a tool) to determine the density of the three observation stations. The result showed that the distribution of white shrimp in the waters of the estuary and surrounding degraded over the past ten years. The highest density at station II is 0.56 and 5/m2and at least at the third station as much as 0.42 and 6/m2The correlation between the density of shrimp with depth as well as the fraction of the base substrate showed that only the depth of the waters who has any significant correlation with the density of shrimp, although the closeness of the relationship is small.
