in order to determine the age structure, growth, and length-weight relationship of the mudskipper, periophthalmus waltoni, from coastal mudflats of qeshm island, soroo and bandar-pol, in hormuzgan province, iran, we collected 192 individuals in february 2007. age was determined using the second pectoral radial bone and year class was based on length-frequency distributions. growth was descr...

In this paper, the author presented a modified Chen and Chung’s model considering that the process mean may not be equal to the target value when the process is in the in-control state. Taguchi’s asymmetric quadratic quality loss function will be applied in evaluating the product quality. Subsequently, the modified economic manufacturing quantity (EMQ) model based on modified the Chen and Chung...

The analysis shows that there is no intrinsic oscillation in the relation between frequency and length of words. The rise of oscillation is caused by using moving averages for smoothing the extremely dispersed data.

the objectives of this study were to determine the age, growth, mortality and exploitation of a commercially important fish of northeastern mediterranean sea, mullus barbatus from the karatas coast of iskenderun bay during september 2002 and april 2003. a total of 212 specimens of red mullet were collected by monthly sampling using traditional bottom trawl net by commercial vessel (coskun reis,...

the length-weight relationship (lwr) and condition factors (cf) of 180 the oriental river prawn macrobrachium nipponense collected from southern coasts of the caspian sea from may through september 2012 were studied. shrimp samples were taken and immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, weight and other external features of ...
