Abstract

Scylla  spp.  commonly  known  as  the  mudcrab,  has  a  huge  market   demand  all over  the  world, particularly  in  South  East  Asian  countries. This   seafood  delicacy  is  considered  as   one  of  the  tastiest  of  all  crab  species.This  is  available  worldwide  and  is   mostly  sold  live  in  international  markets.  There  is  an  unmet  demand  for  mudcrabs  internationally  and  this  has  led  to  over-exploitation  of  this  species  in  many  area  across  the  Indian  coast.  Indiscriminate  exploitation  of  natural  mudcrab  resources  disregarding  the  size , maturity  status ( berried  or  not)  and   physiological  status (  water or  hard)  has  resulted   heavy  pressure  on  the  wild  population. The  huge  market  demand  for  mudcrabs  ( Scylla  tranquebarica.)  has  attracted  the  attention  of  both  fishery  scientists  as  well as  enterprenuers  as  a  potential  candidate  species  for  commercial  level  aquaculture. However,culture  of this  species  couldnot get momentum for want  of  adequate  seeds.  Offlate  the  breeding  and  seed  production  of  this  species  has  been  standardized  at  this  institute,

                     These  backyard  ponds can  well  be  utilized  for  small  hatchery  operation  of  S.tranquebarica  seeds and  thus  can  improve  the  socio-economic status of the  coastal  fisherfolks .  In this  paper,  the  techniques  developed  such  as  brood  stock  management, live  feed  /  water management  and  larval  development   for  success  of  seed  production  of  mudcrab  species are  incorporated.S.tranquebarica.  Besides  these, survival  and   economics  are  also  discussed  in  this paper.
