Shrimp communities of the coastal habitat of the Sonmiani Lagoon were shown to be dominated by family Penaeidae. Seasonal variation in the relative abundance and species diversity of penaeid shrimps was derived from sampling of 2554 individuals representing twelve species of three genera. The results showed that species of the genus Penaeus dominated over those of the other two genera of penaeid shrimps i.e. Metapenaeus and Parapenaeopsis. The most abundant species of penaeid shrimps were Penaeus indicus (67.50 %), Metapenaeus affinis (13.31 %), Penaeus merguiensis (12.02 %), Metapenaeus brevicornis (4.26 %) and Metapenaeus stebbingi (1.60 %), respectively. Relative abundance varied seasonally within the species and between the seasons. Highest species richness in the lagoon was observed in the period of SW monsoon and the lowest in pre-monsoon season, whereas Diversity (H') was found to be highest in post-monsoon, and appeared to be influenced by the equitability (J) of distribution of individuals among the species. Temperature, salinity and pH influenced both the abundance and the diversity of shrimp fauna in the lagoon.

巴基斯坦Bal路支斯坦省Sonmiani湾泻湖沿岸对虾对虾的丰度和物种多样性的季节性变化

Sonmiani泻湖沿岸栖息地的虾类群落被显示为Penaeidae科。对虾的相对丰度和物种多样性的季节性变化是从代表3个属的12个物种的2554个个体的采样中得出的。结果表明，该属物种南美白对虾为主的对那些其他两个属虾类的即。对虾和副对虾。对虾最丰富的种类是印度对虾（67.50％），亲子对虾（13.31％），梅尔圭对虾 （12.02％），短对虾（4.26％）和斜纹对虾（1.60％）。相对丰度在物种内和季节之间随季节变化。在西南季风期间，泻湖中物种丰富度最高，在季风前季节中最低；而在季风后，多样性（H'）被发现最高，并且似乎受公平性影响（J）。种间个体分布的关系。温度，盐度和pH值影响泻湖中虾类动物的丰度和多样性。
