the attack of the killer sauh worm



Information on lernea from wikipedia:

"Lernaea (also spelled Lernea) is a genus of copepod crustaceans commonly called anchor worms, parasitic on freshwater fishes. They mate during the last free-swimming (copepodid) stage of development. After mating, the female burrows into the flesh of a fish and transforms into an unsegmented, wormlike form, usually with a portion hanging from the fish's body"

- lernea/anchor worm/cacing sauh/scientific name:henneguya shaharini
- cacing ni pandai menyorok kadang2..belek2, ermm adela yang tersangkut..ikan bile kene x meragam sangat, non leathal..tp ikan x selera makan..yang jadi leathalnye bile mende tu da lama hinggap akan jadi luka/ulcer tinggalkan telur, dan merebak ke ikan2 lain.
-nak cabut boleh, but make sure tarik gunakan tweezer dgan akar2 cacing skali..cairkan potmat ngan air suam, dab ngan cotton bud kat cacing & cacing akan longlai..tapi kalau satu kolam effect? seekor ikan kne x5 cacing...jenuhh2...
- try bath kan ikan ngan garam 5-10ppt @ garam 5ppt+potmat @ formalin + garam
- kadang2 jadi..tp lambat cket..tanye otai2 ley pakai racun serangga untuk tanaman??, dipterex/trichlorfon..tang ni ley bunuh cacing plus anak cucu cicit diorng skali...wallahualam

updates...

1)My observation when using potasium p. + salt is that not all fishes recover from the worm as a result of the frequent use of the same treatment
2) i went to a local agriculture/crop supply store & couldnt find any of 'dipterex/trichlorfon, instead i got Malathion (57% EC) for a trial treatment for the infected marble goby..
3) it was said that this insecticide also has the potential to treat fish infected by lernea (mostly carp & koi )..no information on the usage of malathion on marble goby yet
4) required/recommended dosage to be tested on the fish:

i) 2ml/1,000 gallons
ii) 5ml/1,000 gallons (best)
iii) 10ml/1,000 gallons

p/s - these treatments were succesfully used on koi's, so i'll have a try on my marble goby.. let see later on the outcome..

puyu@climbing perch




i dont no why, but i just love this fish...very cute but nasty..hungry at all times..at the momment, 2 ponds for its culturing....approximately 8k of the fry's are cultured in earthen ponds to get a maximize growth..Main problem of rearing this species is during it's baby fry stage..must be fed frequently, 4 to 5 times daily..or else the big ones will wrestle the small ones/cannibalism...beware though this can result to daily losses of your fingerlings.....

new fry's from rawang...







  • new fry's were bought from rawang.
  • fetched my friend milin, he wanted to follow
  • arrived there around 2pm++
  • 100 ketutu fry's were packed in 2 boxes of polysterine, added with small volume of water + anti ammonia..
  • then had lunch, went to see some friends in bestari jaya..
  • headed home around 5pm, and reached sabak bernam at 7pm..(journey of 5 hours)
  • then weighed the fries..100 fry's = approx. 9.5 kg
  • looks though like the fry's are dead (see above pic.)..inserted them to the quarantined pond & swam as usual
  • after 5 days, 2 died during the quarantine period = 2% of mrtality rate
  • considered as success in this delivery method
  • it reduces the fish stress and delivers sort of a sedating effect during transportation
