Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...

متن کاملFinger Length Ratios in Serbian Transsexuals
Atypical prenatal hormone exposure could be a factor in the development of transsexualism. There is evidence that the 2nd and 4th digit ratio (2D:4D) associates negatively with prenatal testosterone and positively with estrogens. The aim was to assess the difference in 2D:4D between female to male transsexuals (FMT) and male to female transsexuals (MFT) and controls. We examined 42 MFT, 38 FMT,...
متن کاملA Critique of the Use of t-ratios in Model Selection
It is a common practice to use t-ratios to select models in empirical asset pricing. In this paper, we show that such a practice could lead to the acceptance of very poor models. As an illustration, we examine a simple version of the widely used cross-sectional regression methodology and find analytically that variables with the highest t-ratios may not be highly correlated with expected return...
متن کاملLength-Weight relationship, Condition factor and length frequency of rock oyster, Saccostrea cucullata in coastal waters of Persian Gulf
This study aimed to achieve length frequency, condition factor and length-weight relationship of the rock oyster, Saccostrea cucullata in the coastal waters of Persian Gulf. Sampling was carried out by 0.25 m2 quadrat through intertidal zone from winter 2015 to autumn 2016. According to the results, length-weight relationship calculated as W=0.000004L2.79 for both sexes. In addition, coefficien...
