ABSTRACT
A study was carried out to investigate the weight-length and width, and length-width relationships of juvenile blue swimming crab, Portunus pelagicus, population living in the seagrass beds of Sungai Pulai, Johor, Malaysia. Samplings were done at two different sites of the seagrass beds (i.e. Beting Laut Tg. Pelepas and Beting Merambong) from 14th - 15th June 2002. A total of 38 males and 55 females were taken randomly using a scoop-net and preserved in 10 % buffered formalin for further investigations in the laboratory. It is found that the growth pattern of juvenile blue swimmer crab males and females tend to be like isometric (b= 2.8174-3.1543) in both of the stations. In general, relative growth of body dimensions of juvenile has positive (r= 0.9661-0.99974) and significant relationship (P<0.01) with the growth of carapace width and length as predictors.
