length-weight relationships of garra rufa, in the tigris and persian gulf basins of iran
Authors
abstract
garra rufa , a bottom dwelling freshwater fish and native to the middle east, is distributed in the southwestern of iran and the tigris basin. considering the importance of length-weight relationships data of a species in different habitats, the length-weight relationship of g. rufa from 13 rivers in the persian gulf and the tigris basins was explored. the value of exponent b ranged from 2.74 to 3.19 with average of 2.99 in the tigris basin and 2.96 in the persian gulf basin which was in normal range (2.5-3.5). as the length-weight parameters were concluded for each location separately, this information would be useful for further population dynamics researches.
