Population Characteristics, Length-Weight and Length-Length Relationships of Acetes vulgaris (Decapoda: Sergestidae) in the Coastal Waters of Pontian, Johor, Peninsular Malaysia
S.M. Nurul Amin,
The population structure, length-weight and length-length
relationships of Acetes vulgaris were examined based on 1141 specimens
collected in the months of June and July 2006 from Pontian, Johor Bahru.
The morphological characteristics of A. vulgaris were examined
and the result was found to be similar when compared with the previous
research. Mean length of males was 23.18 ± 2.95 mm while for females
was 23.91 ± 3.53 mm. The range of total length for the males and
females was 14.00-33.00 and 13.00-32.00 mm, respectively. The relationship
between the total length and body weight of A. vulgaris was W =
0.0178L2.6368 (r2 = 0.829) for males and W = 0.0082L2.9144
(r2 = 0.902) for females. The carapace length and total length,
relationship for males and females were CL = 4.1844TL + 2.3983 (r2
= 0.732) and CL = 4.0872TL + 1.8879 (r2 = 0.732), respectively.
The sex ratio of female to male was found to be at 1: 3.27 with the number
of males exceeded that of the females.
