| dc.description.abstract | The research was conducted in Brebes district coastal waters Central Java Province for twelve month from April 2008 to March 2009. The aims of the research is to know Length/Width-Weight relationship of blue swimming crab. Survey method was used in this resea rch. All of sample measured its length, width and weight. Regression analysis was used to describe length/width-weight relationship and condition factor. A total of 844 crabs sample consist of 367 males and 477 females. Range of crab carapace length are 2.1 em to 7.5 em and weight range are 6.53 g to 253.24 g. Length-width relationship of male crab described in regression equation CW = 1.8479 CL + 1.1787 with determination coefficient R2=0.9386. While, its Length-Weight relationship is W = 0.5374 CL3.0398, with detennination coefficient R2 = 0.9624. Length-width relationship on female crab described as W = 1.7993 CL + 1.5042 with determination coefficient R2 = 0.9407. Length-Weight relationship described as W = 0.7239 cu.ss93, R 2 = 0.9491 (CL=Length, CW=Width, W=Weight)-The average condition factor was 58.583 and 6.060 for all crab | en |
