Copepoda [is] lilliputian prawn faction which often attack exterior fish body and gill. This parasite earn life [in] brine and also freshwater and very [is] difficult controlled. member of Copepoda which non parasite often share to medium inang of worm parasite. Many parasite of Copepoda penetrating fish flesh without can be prevented by treatment of chemistry. This parasite have complicated life cycle.


Argulus sp


Argulus sp. [is] of a kind lilliputian prawn which the including into set of relatives of Argulidae and represent ektoparasit. This organism have circular body form [of] pipih like flea, so that [is] often referred [as] [by] fish flea ( louse fish).

Hurt of[is ex- this sucker appliance represent part of which is [is] easy to be attacked by mushroom or bacterium. infection of Sekunder this can cause death of fish massly.

attacked [by] Fish marking [is] argulus [is] its body seen to become thin even very weak for want of blood. Ex- its attack earn seen redish chromatic, because happened haemorrahage. If happened attack on a large scale, sp makaArgulus. will seen to form colony around gill and fin.


Way of most effective to prevent this parasite attack [is] by [doing/conducting] draining and give pool chalk and also screening of water. While its operation can be [done/conducted] by using salt condensation ( Naci) or salt condensation of ammoniak ( NH 4 CI). That way also with fish input in condensation of bromex 0,1- 0,2 ppm. Fish input in condensation of lindane 0,01- 0,02 ppm have earned to kill Argulus sp. swimming free during 5 [hour/clock], while dose 0,013 proven ppm can kill totally after 48 [hour/clock]. Perendaman in condensation of neguvon 1 gram per litre irrigate during 10-30 effective minute enough to fight against this parasite.
