"Lernaea (also spelled Lernea) is a genus of copepodcrustaceans 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
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 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.....
all rods were near pintal's rod no get some luck.....
abang, the lone ranger fisherman
from left: pintal, mat, milin & abang
'tasik maniam' is located in the inland of the batang berjuntai district area...the fishing spot is recognized as the home for many species of 'patin'...it started as a mining site during the british era and evolved to become a lake after mining activities were stopped... the lake then was used for fishery activities in breeding the 'patin species'..The breeding of it ended as the lake flooded due to heavy rain that caused to the escape of the spesies..i was also told that although it was a great loss to the fish farmers, they discontinued the breeding activities due to low demand for patin fish during that time.....
on 4th of september, we had an expedition to this site in hunting the patin species...guided by 'pintal', our friend who is a local resident there, we headed to the location around 12pm...our intention was to go there by car, but after being advised on the poor condition of the road track, we resorted to 3 motorbikes..the journey took about half an hour of passing oil palm estates before reaching the lake..
12.30pm : took our fishing gears and started for the hunting...known to many, we used 'dedak ayam' as our official bait for that day...patin fish is a devotee to 'dedak ayam, but it's a matter of how well it is mixed with other ingrediants that will attract them..but i was a little pissed off as we left behind some important fishing gears......
3 hours of waiting, still no sign of the patin...we shifted spot...still nothing.....Suddenly, pintal's rod bended...he reacted immediately but disappointment shrouded us all as the fish managed to escape...the we only notice that that pintal used 'gardenia bread' for his bait..hahah..patin's appetite gone wrong????
around 4pm, milin landed a belida ...followed by ikan putih...he was very proud of himself that day as he was the only one manage to landed some fish....although the fish he caught were fish of size 'S' ...hehehe..
a bit dissapointing that day..no luck, no patin, no big fish...6pm, we headed home...........
here's how i learnt, mostly got information from sifuu’s especially from course i attended before, tn hj...forum/internet, fry trader, from people i met, friends, dad’s opinion – he’s a kelah expert, etc..
combination of above + thoughts in mind + experiments + current experience = bellow summary ..
the more the ketutu died, the more i learnt and hopefully will make me 2 b more preventive in the future..until now,these are my understanding on the fish so-called ‘Hantu’..all the bellow explains.......
Spec of my pond.. 10x5x2.5 kanvas x 8units
1. actually, kanvas is the last choice but since its a trial, will convert to concrete pond/earthenpond in the future..for the filtering, i just use natural filter...pro's n contra of kanvas= quite cheap,fast,easy setup/ but couldnt sustain temperature level?/has its life period 2. fish release wastes/ammonia.. quatic plant to absorb ammonia in water..
3. aeration/airlift..circulates and gives a mild flow to water, supplies 02+releases unwanted@toxic gas contained in water + creates water circulation..since water is covered with plants d.0 will be generated from this.. p/s - ketutu couldnt cope with heavy flow/is a water breather (not air breather) .. saves electricity,i use atman blower for all 8 pond. 4. sunlight, to make sure the keladi bunting lives.. completes the natural filter..for solid waste, i'll clean them once a while 5. the warmer , the better..vice versa,parasite/bact can in cold water conditions & more active in cold wheather..so the pond is just covered with 50% orkid net to allow sunlight get through.. 6. ph.....seldom check.. .ketutu once settled in your pond, its a hardy....
7. salt 3-5 ppt, elements from earthn pond to create a natural environment.. 8. change water volume 10-20% monthly.kdg2 tak
1) normal transprtation (polystrine+water+oxy) - first batch came from perak..i ordered 500 Wild ketutu fry’s ranging from the SiZE of 5-10inches, & seller came by van - at a glance, some look healthy,some not.. qurantine with salt + potmat for 2/3 days before grading and transfering them to the ponds - 20-30 died during this period ( i suspect to the overload stress of fish carried from the long journey)..jalan jauh2, pening ikan
- already tested it with small quantity fry’s..maybe its a better way to reduce fish stress during transport..
1) here comes the hardest part..lack duration of fish quarantine answers it all 2) after transfering the fish to pond..day by day, fish kept on dying 3) so what i did was i had a close check using my naked eye at every single fry and guess what i found out 4) – learnea/hook worm + fungus on unhealed wound (like spora) +white spot + kembung perut/stress + mati sparuh bdn/ekor +etc + etc +etc +etc
5) Summary : not only quarantine procedures play a major part, i also suspect the quality of fish fry/handling of seller before transported is very low+i also lack in experience.. 6) Overall 20% mortality rate of the first batch 7) Moral of the story, prolong the quarantine period..do a close check to every singly fry - kalau larat..
p/s – sometimes, different disease comes with different medicine..experiment with them
#i've tried potmat/otc/acriflavin/salt/formalin/ hydrogen perokside - med. mostly got it when i attended hj hanafiah’s course + bought at aqua shop + pharmacy
- potmat + salt is the best.... -.use salt as a remedy/but it takes time..most of the mortality rate of my fry comes from treatment
-so handling of these fry are very important to cut down losses..
How i fed them?
- i give live fish/some of them pellet for trial/some trash fish= x kisahla mana2..janji ikan ngap & nak membesar
- feed accordingly to its weight - in the meanwhile, bought 10k of 1 inch keli fry’s..also tried to hatch keli fry,..gi pasar bli keli.adela cuba cucuk2 ovaprim tuh..bg mkn artemia hari ke3++ dup2, adela 300ekor idup...jadila
- thers a quote from a domestic blogger claiming that keli has high protein as compared to other fishes - seluang/kap etc.. - i agree..my cousin had a trip to indonesia, the breed keli to feed ducks..itik depa besor2.. - one more thing, keli swim x laju mane, snang ketutu nak terkAm..but economical??
B.B champ..haha..(tasik btg berjuntai near unisel)..me with a patin..after 3 painful hours of waiting...an approx. 2kilo patin was landed at tasik b.b..credits given to the 'mata bomb' that attracted the fish..
here's a story...Sunny told us that there's a free fishing spot in subang..we went there one night..wow...amazing..with lights & a pretty clean spot to go fishing...45minutes afterwards, wak kang (pic. above) landed a patin...not bad!..around 1kilo..but suddenly a man came and asked us for a deposit..?????????ermmm...one rod RM30 for 3 hours...hahaha..what da hell..we thought it was free to fish there...so the night came to an end as we packed our stuffs and headed to a new location...
jamming?..already 3months i havent touched my guitar...nyways, kimi, kiman, mawi, all are busy with their work....
