Environmental biotechnology employs the application of genetic engineering to improve efficiency and cost, which are central to the future of widespread exploitation of microorganisms to reduce the environmental burden of toxic substances. It is hoped that in future, the application of microorganisms coupled with genetic engineering techniques, will make a major contribution to improve the qual...
hoosing the appropriate site is important in the construction of units such as agricultural processing industries. In this study, we try to determine the factors affecting the exploitation of the agricultural processing industries and measure the share of location as one of the important issues in locating research. The 2572 data were collected from the Agricultural Jihad Organization of Mazand...
Length-based analyses were conducted to assess the stock of the green tiger shrimp Penaeus semisulcatus. Monthly carapace length frequency data were collected from commercial catches at two main landing sites on the Yemeni Red Sea coast for eight months. Growth parameters, mortalities, exploitation rate and yield per recruit were estimated for this species in this area. The estimated growth par...
