Lernea Cyprinaceae
L. cyprinaceae [is] of a kind globular lilliputian prawn [of] length like worm. [At] part of its head there are organ looking like yoke, so that this organism [is] recognized with the title yoke worm ( anchorworm). By the instrumentality of organ this is yoke worm gum in [him/it] to fish body. During its life, natural yoke worm thrice change of [his/its] body, that is nauplius, adult form and copepodid. The duration one cycle live depended from environmental temperature, in Indonesia, generally reach 21 - 25 day.
[At] stadium of copepodid, this yoke worm [of] life [in] around fish body and nip husk / fish mucus. [At] this stadium, the worm very sensitive to some type of obat-obatan. Entering adult stadium, this worm [of] worm divided to become two group, that is stadium of cyclopoid adult stadium and. During stadium of cyclopoid, lernea live [in] around fish body as well as [do] not hold up to influence of medication.
female Yoke worm will jab its head to husk network / fish flesh. [At] part of which [is] jabed will seen hurt and swell, but because its size measure still is undersize, rather difficult to see [it] with the naked eye. Adult individual have earned to be seen with the naked eye. Part of its body which there are outside fish body will see bigly, because having a couple of egg poke. If its egg hatch, hence nauplius will swim exit from within poke to look for fish.

Picture - 20: Cycle live Lernea cyprinaceae
1. stadium of Nauplius ……………. 4. Stadium. adult
2. stadium of Copepodid ……………. 4a. fish. attacked [by] [is] lernea
3. stadium of Cyclopoid.
Most of all bream type can be attacked by this yoke worm, especially [at] seeding season or conservancy of seed. attacked fish generally experience of hurt [at] its body and seen the existence of yoke worm which patch. Prevention to yoke worm attack can be [done/conducted] by [doing/conducting] draining of pool, filtering water before poured into pool or use chemicals to eradicate yoke worm [at] stadium of nauplius and of copepodid. Strive operation to difficult adult yoke worm attack [done/conducted], because this worm have husk of khitin which hold up to influence of chemical compound. Usage of effective scissors enough to fight against adult yoke worm. Cut part of yoke worm body which patch [at] fish body and [is] immediately annihilated by burying or burning [him/ it], while part of its head [is] let to stay in fish body.
To avoid the happening of infection of sekunder, fish soaked in condensation of tetrasiklin 250 mg per 500 litre irrigate during 2 - 3 [hour/clock]. this Immersion process can repeat [by] during 3 day successively. Operation of yoke worm with chemical compound earn [is] also [done/conducted] soaked fish which [is] attacked in condensation of bromex 0,12 - 0,15 ppm. Yoke Caring [at] stadium of copepodid can be murdered soaked fish which [is] charged into in condensation of dipterex 0,25 ppm during 4 - 6 [hour/clock]. soaked with condensation of Nacl and of PK effective enough, but because its dose reside in a little below concentration of lethal to fish, way of this seldom be used.
