PostSubject: Is it Worth Quarantining Koi?   Is it Worth Quarantining Koi? Icon_minitimeFri Oct 17, 2008 12:54 pm

Hi,

I ask this question in all honesty and for very good reason.

I have been collecting koi for 36 years. I have witnessed many different interpretations of quarantining koi. I have my own method of quarantining. I was discussing quarantining koi the other day with a guy who visits ponds, treats sick fish and assists koi keepers every day. He has around 800 people on his books.

Here is a hypothetical situation - if a koi dealer sells 100 koi on a weekend to 50 customers (this is starting to sound like a primary school maths question) and of those one or possible two koi keepers have problems why do we only concentrate on these "problems" and not the successful introductions?

Of the 50 customers, how many actually have quarantine facilities? Yes we would like them to have quarantine facilities but how many actually have?

Of the one or two people who do have problems how many had problems in their ponds AFTER introducing koi that were first quarantined.

We may think it is a good idea to raise temperatures to trigger possible KHV, we may think it is a good idea to bomb the quarantine ponds with anti parasite mediation and anti biotics but then we do the same to the main pond when we introduce the koi after quarantine. Also how many koi keeper actually have the facilities to do these procedures?

Further, there are some other factors we never take into account. Ten people can purchase koi from the same dealers tank and only one has problems. Even if all ten do quarantine. (this is based on a real life situation this year).

It has been known for as long as aquaculture has been around that introducing new fish to a system is ALWAYS risky no matter the source. There are some things that can be done to minimise the impact of new fish but there is no guarantee.

I have, over 36 years, introduced new koi many, many times directly into my collections and never had problems. I have introduced koi directly into my collections a few times and picked up problems.

I think we need more information on the number of koi keepers who do have problems, the number of koi keepers who do quarantine and the numbers of koi keepers who do not quarantine and do not have problems.

The biggest problems with the introduction of koi are bacterial and viral infections - things we cannot see or predict.

I saw a lab report on a koi from a sick koi collection last week. The lab tested for bacterial problems - which were the root cause of the sick koi. The bacteria on the koi were resistant to every available anti biotic.

I would be interested in your views and how you quarantine. If you do not quarantine have you had problems. If you do quarantine - have you had problems?

Regards,
Chris

It is a very valid question, especially in view of the fact that very few people does actually have the facilities. Only about 20% of my clients do have quarantine facilities.

I suppose it boils down to the risk that you are prepared to take, depending on the value of the new fish and your existing stock.

If you have the facilities, I believe it is senseless not to quarantine. If you don't have, you should seriously consider to get one.

I wrote this article in Afrikaans on the time required:

1. KHV: Die heel belangrikste aspek om te oorweeg met bepaling van die tydperk, is om te bepaal of KHV dalk teenwoordig kan wees. Dit sal afhang van of die nuwe aankomeling getoets is vir KHV en of die handelaar reeds behoorlik gekwarantyn het vir teenwoordigheid van KHV met gepaardgaande manipulasie van temperatuur om KHV bloot te lę indien teenwoordig. Die bron van die nuwe aankomelinge speel ‘n geweldige groot rol by die tydperk wat nodig word. Indien onseker, behoort die kwarantyn tydperk ten minste 8 weke te duur met behoorlike inagneming van die ondergenoemde faktore.

2. Temperatuur: Die meeste parasiete, bakterie en virusse is betreklik onaktief terwyl die water temperatuuir baie laag is. KHV sal byvoorbeeld eers sy kleure wys wanneer ‘n temperatuur van ten minste 18 grade Celsius bereik is. Indien visse gekwarantyn word tydens die wintermaande, behoort hulle tot ten minste ‘n maand na die aanbreek van somer gekwarantyn te word. Die "nasties" gaan eers hulle kleure wys nadat dit warm genoeg is. Indien elektriese verhitting gebruik word, beinvloed dit natuurlik die beginsel en ook of die kwarantynfasiliteit binne of buite geleë is.

3. Immuniteit: Die immuniteit van die visse speel ook ‘n baie belangrike rol, wat direk saamhang met die temperatuur van die water en die tyd van die jaar. Aan die einde van die somer is die vis se immuniteit op sy beste en tydens winter weer op sy laagste. Tydens lente, al is dit al redelik warm, het die vis se immuniteit nog nie kans gehad om op te bou nie. Dit neem ten minste ‘n maand van redelik warm weer alvorens die vis se immuniteit weer in volle swang is en kom nie eensklaps terug nie. Dus is dit altyd beter om nuwe visse in die somer by te voeg. Die aanbevole kwarentyn period is drasties laer, en visse kan selfs met redelike veiligheid binne 10 dae bygevoeg word, met dien verstande daar is geen ander faktore teenwoordig is wat ‘n langer tydperk verg nie.

4. Risiko analise: Die tydperk benodig hang baie nou saam met die risiko wat jy as Koi entoesias bereid is om te neem, en dit kan nie bepaal word deur enige buitestaander nie. Daar is altyd ‘n risiko dat jy vis kan verloor weens die aanvulling van nuwe vis, selfs nadat jy vir tot drie maande gekwarantyn het. Die vraag is, hoeveel risiko is JY bereid om te neem met inagnemeing van jou finansiële vermoë. Kan jy bekostig om van jou bestaande kolleksie te verloor. Indien jou antwoord zero risiko is, moet dan nooit nuwe vis byvoeg nie, maar dan kan jy ook nie regtig die stokperdtjie uitleef en geniet nie. Wat ook baie belangrik is, is wat die waarde van die vis in jou hoof dam is, want dit bepaal die mate van risiko wat jy neem om nuwe vis by te voeg.

5. Behandeling tydens die kwarantyn periode: Die tydperk benodig hang ook baie nou saam met die wyse waarop gekwarantyn word. Daar is baie entoesiaste wat hulle visse ‘n Potassium en sout bad gee by aankoms, dit herhaal twee dae later, ‘n skraping neem om te bepaal of daar enige pasrasiete teen woordig is, en indien nie, suksesvol die nuwe aankomelinge saam met hulle bestaande visse voeg. Twee baddens gaan die risikos baie verminder en die tydperk benodig om te kwarantyn verkort. Indien jy toegang het tot ‘n mikroskoop en skrapings neem vir parasiete gaan dit die risikos verminder en eweneens die tydperk en risiko verminder. Indien antibakteriële medikasie gebruik word of selfs soos sommige, ‘n antibiotiese behandeling toedien as voorsorgmaatreël, gaan dit die tydperk benodig verminder. Selfs die kwaliteit van die fasiliteit gaan ‘n rol speel, soos byvoorbeeld die effektiwiteit van die filter, hoeveelheid suurstof en in die algemeen, die kwaliteit van die water. Hier moet ook bepaal word of die teikendam se water gebruik is in jou kwarantynfasililiteit soos aanbeveel, en het jy een of twee van jou bestaande versameling se vis saam met die nuwe aankomelinge geplaas met ‘n daaropvolgende positiewe reaksie deur beide die huidige vis wat saamgevoeg is en nuwe aankomelinge.

6. Die reaksie van die visse tydens kwarantyn: Jy moet jouself die vraag afvra, het die visse positief op die kwarantyn tydperk gereageer. Indien daar enige tekens van probleme tydens kwarantyn was, behoort die tydperk drasties verleng te word.

7. Vertroue in jou handelaar: Buiten wat reeds genoem is ten opsigte van KHV, is vertroue in jou handelaar ook baie belangrik. Daar is handelaars wat visse verkoop ten spyte van die feit dat hulle bewus is van ‘n infeksie. Hulle doen dit want hulle kan nie bekostig om alle verkope te staak net omdat daar ‘n moontlikheid van ‘n bakteriële of virus infeksie onder hulle visse is nie. Hulle maak staat op volgehoue verkope om hul maandelikse verpligtinge na te kom. Vra jouself die vraag af, is jou handelaar dalk een van hulle. Hoe meer jy jou handelaar vertrou, hoe korter die aanbevole kwarantyn tydperk, maar meer belangrik, koop net van handelaars met ‘n goeie naam en reputasie. As daar enige twyfel is oor die toestand van hulle visse, bly weg. As daar ‘n geskiedenis van KHV of gesondheidsprobleme is, bly weg.

Die kruks van die saak is, daar is nie ‘n vasgestelde tydperk vir kwarantyn nie. Elkeen moet dit vir homself uitmaak hoe lank benodig word, met behoorlike inagneming van die faktore hierbo genoem.

As jy bereid is om 'n risiko te neem hoef jy nie te kwarantyn nie. Onder normale omstandighede is ongeveer 4 weke voldoende, en as daar enige risiko is van KHV, moet jy kwarantyn vir ten minste 6 weke in warm water.

People ask me all of the time if they should quarantine their Koi. For me there is only one answer YES!
I've never heard anyone say “I lost everything in my Quarantine Tank/Pond” but what I have heard several times are "I lost everything in my pond.” pale Sad
So yes I think you should quarantine.

Hi All

Yes you must QT Exclamation Exclamation Exclamation A lot of the koi keepers that I know use this for QT TANKS & TRANSPORT TANKS 1000L and dim 1m x 1m x 1m this is ideal for medication as well.
