| Abstract: | Abstract: This study was carried out at mangroves and saltmarsh area of Cox’s Bazar, Bangladesh which is called a nursery, spawning & breeding ground of horseshoe crabs (HSC) for a period of July 2021 to June 2022 to reveal the morphometric variability in different sex of the adult mangroves horseshoe crab (Carcinoscorpius rotundicauda). The morphometric variability for C. rotundicauda as well as to introduce allometry as the method in statistical shape analysis for growth rate in order to protect and monitor the living of this species from the study area. The measurement of total body weight (BW), prosomal length (PL), opisthosomal length (OL), prosomal width (PW), opisthosomal width (OW 1-3), distance between the anal angles (AA), inter ocular distance (IOD) between the compound eyes, telson length (TEL), carapace length (CL) and total body length (TL) were taken for comparative study based on the sex. The study revealed that the females of C. rotundicauda are significantly heavier and larger in size than males except for telson length. The frequency distribution histogram of each parameter was demonstrated for which range the most species are found. All morphometric parameters were then converted into logarithmic value as allometric growth analysis by using the linear equations. The differences in each body parameter between the males and females were observed through the student’s t-test. A positive allometry growth (b>3) was recorded in the relationship between length/width-weight (TL-BW, PW-BW, CL-BW) for both of the sexes while the length/width-length relationships (CL-PW, TL-PW, CL-TEL, TL-TEL) were recorded as a negative allometric growth (b<1) except CL-PW for females which express an isometric growth (B=1). Overall performance showed a strong correlation between all body parts of C. rotundicauda. The changes in body dimensions of the C. rotundicauda population indicate that the relationship could indirectly be influenced by population density, feeding efficiency, food availability and local environmental conditions. The results are expected to be used as baseline data for the horseshoe crab management plan and action. Besides, follow up study on the relationship of horseshoe crab population growth are needed in developing strategies on monitoring, conservation and breeding of horseshoe crab. |
