Population Dynamics of the Indonesian Mantis Shrimp, Harpiosquilla raphidea (Fabricius 1798) (Crustacea: (Fabricius 1798) (Crustacea: Stomatopoda) Collected from a Mud Flat in Kuala Tungkal, Jambi Province, Sumatera Island

Abstract: This  study  aim  was  to  reveal  the  population  structure,  growth,  life  span  and  exploitation  rate  of  mantis  shrimp (Harpiosquilla  raphidea Fabricius, 1798). This research was conducted in Kuala Tungkal, Tanjung Jabung Barat, Jambi  from  July  2009  to  June  2010  and  partially  carried  out  periodically.  The  results  showed  the  difference  in group size distribution between the mantis shrimp caught in the intertidal and those caught in subtidal areas. The length of the mantis shrimps in the intertidal area ranged from 25 to 233 mm with the dominant length was 79-96 mm, while in the subtidal area the length ranged from 160-366 with dominant length between 193-258 mm. Growth  coefficient  (K)  was  0.14  for  males  and  0.11  for  females;  while  L∞  was  the  same  for  the  two  sexes,  i.e. 381.68 mm. The life-span of the shrimp was estimated to be 6.7 to 8.5 years. The value of exploitation rate (E) was 0.42 indicating a not optimum exploitation rate of the shrimp.
Key words: mantis shrimp, growth, exploitation rate, life-span, Kuala Tungkal
