Humpback  grouper  (Cromileptes  altivelis)  or  also  known  as  polkadot  grouper  is  one  of  the excellent  fish  commodities  in  Indonesia which  has  trading  value  reached  $  90-150/kg. As  a  consumed fish, humpback grouper are needed  for beverage at  luxuries  restaurant and hotel  in  the world. As major export commodities  in Indonesia, since the 1990 s   the techniques of grouper cultivation  in float net rats are  enhanced  to  fulfill  international market  demand. Humpback  grouper  fish  cultivation  techniques  in float net cages cannot be separated  from  the problems  in any cultivate activities, one of  the causes  is a disease and one of the diseases that rushed humpback grouper is parasite. The disadvantages that caused by the parasite is fish’ weight loss. The purpose of  this  study  is  to determine  the  types of endoparasites  that attacked  the digestive system of humpback grouper (Cromileptes altivelis) in float net cages and also to discuss the prevalences of endoparasites that attack the digestive of humpback grouper (Cromileptes altivelis) in float net cages.  The method of this research is descriptive. The sampling was done in once for 60 fishes with the length range of  fish  is around 15-20 cm and 4 months old  from  the float net. The number of each  fishes samples  that were  taken  5-10%  from  the  total  of  population, where  the  number  of  humpback  grouper populations  in each  raft  float net are 200  fishes. The main parameters  that observed  in  this  study were endoparasites  identification  species  that attack  the digestive  system of  humpback grouper  (Cromileptes altivelis)  in float net cages and the prevalence rates for each endoparasites. The supporting parameters  in this  study  were  the  water  quality  in  float  net  cages  which  includes  temperature,  pH  and  salinity  are measured during the sample taken. The  results  showed  that  60  samples  taken  from  four  float  nets  6  fishes were  positive  infected endoparasitic  of  trematodes  and  nematodes,  besides  4  fishes  are  positive  infected worms  Echinostoma which belong  to the class of Trematodes and 2  fishes  infected worms Camallanus carangis  that belongs to  the  class Nematoda. The  prevalence  values  for  each  of  the  worm  are  6.67%  for  Echinostoma  and 3.33% for Camallanus carangis. The research concern the  identification and prevalence of endoparasites in Humpback grouper at hatchery  is needed  to early  finding out the attack of endoparasites and  to break the flow of  endoparasitic spreading.
