Some biological aspects of Banana shrimp (Penaeus merguiensis) in the protected area of Hara

This study was conduced to investigate some biological aspects of Banana shrimp (Penaeus merguiensis) in protected areas of Hara in the Khuran straits international wetland. Sampling was carried out by four methods including trawling, stake net, gill net and trap from September 2016 to September 2017. A total of 745 specimens (448 females and 297 males) were collected and measured biometric data. Mean, maximum and minimum carapace lengths were recorded at 20.66, 43 and 5 mm for males, and 21.37, 40 and 8 mm for females, respectively. The sex ratio analysis was showed that there was a significant difference in male and female sex ratio of banana shrimp during the study period. Length-weight regression model estimated as W= 0.0009 L2.748 (male) and W= 0.0008 L 2.807 (female) with coefficient of detection R2 > 0.97. Estimation of growth parameters by using least squares regression analysis indicated that the growth of Banana shrimp in the protected area of ​​Hara (Strait of Khuran) for females and males were CL= 42[ 1-e -1.7( t-0.798) ] and CL= 33[ 1-e -1.43( t-0.91) ], respectively.
