length-weight and length-length relationships in populations of garra rufa from different rivers and basins of iran

this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it was significantly bigger than 3, indicating a positive allometric growth, and in some, it was significantly smaller than 3, indicating a negative allometric growth. in the whole samples, it was not significantly different from 3, indicating an isometric growth.
