  • first spawning this season in oz.

    here are a couple of pictures i took with my camera phone.
    this is the first of around four crops of koi we will do this season.
    maybe six if i want to work harder.
    the koi are mainly yellow ogons or should i say orgons..hmm.
    they seem to sell quiet well over here in aquarium shops and in garden centres so this is why we bred these fish first.
    i did throw in a few other pairs but the offspring are hard to come by from those pairs.

    i estimate that we got about 40-60,000 koi from this run.
    anything from 40- 100,000 or so would be considered a good crop.
    i think there is the opportunity to increase the production of the ponds by about double if i were to have more time to look over them, only recently has this farm had earation added to the ponds so we should see a decent jump in holding capacity before the guys get sick.

    there are only two sets of full time hands on the farm currently with some extra help for harvesting and counting and packing on delivery days.

    numbers ussually depends on brood quality and time of the year for hatching our eggs.

    in one picture you can see the koi in a plastic grading tub which is inserted into water in a wheel barrow and everything under around 45mm long can swim out into the wheel barrow leaving us to sort through the larger fish first as we dont want them getting too big if they are rubbish.
    the najority of the fish come out of the pond at 30-40mm long with around 30 fish that are up to 120mm long.

    we sell everything we produce as feeders and only keep maybe a hundred fish for growing up to larger sizes and we also keep around a thousand fish with nice colour to be sold as select koi at 50mm size for peoples aquarium tanks.

    only now am i concentrating on really getting into the nitty gritty of producing some beuatiful show like fish, and paying attention to pairing.

    in the early years on the farm it was often just mass spawns as it seemed to produce larger crops of feeders but now i have been given permision by the big boss to pair away.

    oh and the cage you see floating with the black plastic guards is what we dump the koi in after we catch them out of the pond.
    we use hand held nets and scoop them into a bucket of colder water and the cages are ussaully floating on the adjacent pond.

    we may use between 6-8 cages to hold them prior to grading depending upon how many are in the pond.

    once graded they go back into cages designated for their size or quality.

    we use about 100 of these cages on the farm to hold stock. they are about 2.4m long by 1.2 wide and around .8 deep.

        you are welcome to come and have a look someday.

        best if you come in a few months when i have some more variety in the fish.

        its yellow yellow yellow at the moment im afraid..

        yes bradley, the camera phone is ok but ill get the proper camera along with me next time and take some closer shots.

        ill get an overveiw of the farm if i climb up one of the water storage tanks so all can see the layout of the farm too.

        it should be an interesting tour for some of you out in koi land.

                Good work with the spawn. One question please. With some states declaring the carp species noxious and the Commonwealth prohibiting import, breeding carp is not thought of as a concern by the Wildlife people in Australia?


                • #9

                  good question.

                  yes definatley concerned..and the concern is reflected in the laws.
                  the laws are there for good reason, somethings have gone a bit too far the things and statements and policies that i hear about. but in the end its there to protect the environment and we all know our environment is a bit screwed.
                  i think two of our states will not allow them into the state at all.

                  as in fully banned. victoria and qld i believe. they have had trouble in the waterways in vic. though its not totally carp related...but most common people are led to believe that it is the carps fault alone. and carp are koi.

                  they (us humans) have reduced the river flows and all the other river degradation you can think of to help screw the rivers up.. taken water from upstream for agriculture so it doesnt reach downstream anymore..ri[pped out bank vegetation. wiped out normal flows of water of and out ofg the land after the rains.

                  but yes there are carp around down there in the wild, they catch them out for fertiliser or leave them on the bank to die.
                  they may well compound the problem in the rivers but the native fish have no chance anyway anymore with or without the koi. it is part and parcel of normal agriculture and removing massive quantities of water flows and damming it up. once you change the river to something that the fish havent evolved around they are going to not breed or turn into fingerlings or whatever. while others that have evolved around such new conditions can survive. koi can live in stagnant mud comapred to out native fish which have only evolved to clean waters running, cetain temps etc.

                  if i harvest a pond with koi and our natives side by side the natives can be all dead if things get a bit rough.
                  this means that if i want natives to stay alive enough to make money from them i have to harvest differently altogether.

                  in this respect i think that someday we will consider ourselves lucky that we have any fish, be it non indigenous or whatever in our waterways.
                  i relly see no great improvemnets or turnarounds in our water systems now we have come this far as humans in our ways of can stock new fish in but its not gonna help if they cant establish a population in the water thats there. i think we dont understand enough of the complexities of what we have done.

                  in NSW where i am, there is strict fisheries policies before you can have a license to breed koi or any non indigenous fish for that matter, it makes sense to me mostly.good intentions. if you are a greeny you can be happy with the way the law is.
                  go check out the nsw fisheries barramundi protocol and youll see what i mean.

                  fully netted. 500 m from waterway. no pond discharge.big effluent settlement areas etc.
                  as well as that we are on a salt river and ive never seen any koi in the creek near us. if they got in there theyd die first high tide.
                  you cannot start a farm up in a risky area or bad land formation and things like that. im sure some people would find our rules amazingly complex compared to some areas.
                  the approval process goes through many government organisations.
                  it has been tailored with total concern to the environment among other things.
                  as you mention national parks and wildlife, council, nsw fisheries. land and water etc. really it is not an easy race to run to get a license.
                  if you fit the criteria you could have one.
                  but try fit the criteria and pay back the money it cost you to set up and youll know about it. most farms will fail.
                  These days its very hard and costs a lot to get a license. your farm must near be perfect. so we have a situation where there is a lack of aquaculture growth now adays. i imagine if you want to farm anything else it is fairly easy comparitively. so yes the greenies or whatever you call us/ or them have been told that fish farming is bad for the environment while in reality everything that man does is bad or much much worse. its like aquaculture has come at a bad time and has a lot of opposition while you can cut a forest out turn it into pasture and grow any farm animal you like and fertilise the paddocks as you like.

                  if you own a backyard and any aquarium fish you can breed if you like, as long as they are not for sale. that breaks the law. that means that anyoine doing breeding is under the scope..well if they sell amyways.

                  what we have is koi and all types of fish breeding naturally with each other probably in every town throughout the state.
                  i have seen koi swimmming in two other freshwater creeks.
                  i wanted to catch one of them cause it was very beautiful bekko.
                  one was next to a cemetary that had koi in a pond and the other one was near a backyard koi operation. it happens, they know it happens and they dont like it. you can get a spill in time of rain, but im sure its not the normal.

                  there are goldfish also in a few creek systems up the coast but i dont see it as a huge man made disaster. they are brown of course.
                  take a look at the plants we have around the place, most of them in our yards and parks are not locally evolved. look at our pets, its everywhere.
                  in some instances it causes a problem. especially if you want to see it that way.

                  i think the laws to stop importation from other countries came in in around late 1970s and they were going to ban them altogether but i believe the koi assocation was formed and they lobbied to keep their fish.
                  i guess they argued that it was not koi keepers that was cause for the carps to be in the rivers. though i dont know my history that well casue im only young and a bit ignorant to what went down.

                  like what do you do? stop people owning cats dogs cows pigs and anything that doesnt originate here?

                  id like some KHV free stock, it shouldnt be a problem to replace some of my fish with new lines straight from japan.
                  if a farm could do that then the population ok koi lovers could have them also without risking the diesease evrytime. whats the difference between supplying top line fish compared to fish with lesser qualtiy in regards to environmental issues??
                  it wouldnt casue an environmental problem. yet im not allowed. so im stuck with what we had before the laws came in and what little improvements have been made.
                  i think that farms should be able to have koi lines tested for disease just as the massive import aquarium trade undergoes quarrantine before release to the markets. if we could have them approved khv free from known khv free farms then no one is going to let those broodline koi into the rivers.

                    Thanks for the information Ranskye, interesting and provocative reading. I think you might have the answer for limiting the carp population that would satisfy both groups, States and koi owners. Have koi shows that grade the fish with proffesional judges. Only top of the line koi will be allowed to live a normal life span. Culls, as seen by this neutral party ,will be used for fertilizer to feed the pasteur grass that grows where the forests and natural streams once were.

                      yes kingkong, thought provoking for sure and i guess you could look at this from any angle. my thought only come from what i know.
                      im sure if i had koi "plaguing" my river id be a tad peed about it.

                      the problem fish in the big rivers are brown europeans i think.
                      let there by people that didnt know it was not such a great idea.
                      you cant educate everyione that letting non indigenous fish out into the wild has repurcusions for the environment.

                      if there were any coloured japnanese style koi in those systems to begin with i imagine only the brownish ones would survive the predators.
                      they have carp round ups and also ive heard its aginst the law to catch a carp and let it go back in.

                      its just my thoughts that by allowing top line koi into the country as broodstock then it would not affect the rivers anymore than the koi that are already produced on farms here. you simply cannot have koi in the country with no risk.
                      but koi are here and here to stay, they are produced in large numbers legally.
                      new top line japanese lineage fish wouldnt really increase the risk.

                      what i think is that when you have a law that stops the top line being imported for our breeding pool then you have a situation where people, great koi lovers, will break the law and import fish illegally to have that genetic and this results in fish that could possibly contain the KH virus being brought into the country instead of having a fish that has been health checked appropriatley.
                      im pretty sure that the virus has actually recently entered the country via this pathway so i believe that the rule has had a negative effect in this regard. everyone would like some nice fish like the ones we see on the internet right?

                      i think the rule against importation was originally concieved to avoid koi running wild in the rivers but when you have an industy that produces koi here anyway its up to people to be responsible with koi so they dont get out.
                      to say the rivers are well protected becasue of the non importation of koi laws is probably a false belief today seeing as there are probably around ten million koi living in ponds farms and tanks in this county already legally.

                      i just cant see any harm being done by allowing a few disease free batches of top koi lines inot the country for breeding purposes.
                      i think it would be a postive only.
                      im not sure but it may even be possible to seek permission to do such a thing.

                        "im pretty sure that the virus has actually recently entered the country via this pathway"

                        Is this a rumour? I have not heard anything.

                          bradley, yes maybe it is a rumour, though ive heard the virus has been found in some peoples koi and i believe it. i dont believe the virus has entered any farms here and its best to try keep it that way.
                          i have been warned that it is in the country and to exercise care when sourcing new broodstock for the farm. i guess it is not well known as it is not widespread but likley already has been isolated.
                          i was told that the virus had likely come in with illegally imported fish and i guess this would be the most obvious pathway as it is likely that some importation has occured since the outbreaks overseas.
                          i cant say im an expert on the virus itself but to say that no koi have been imported since the 1970s ban would be an untruth. laws only try and prevent things happening but it dosent always work.
                          i feel its just better to be on the side of caution.

                          do you know if the virus can be passed on via milt alone?
                          until i know more info it may be a way of getting some better genetic into the farm without risking the virus and without costing a packet for the fish to be tested for it.

                            i suspect


                            I suspect it is a rumour rather than fact. I dont know of anyone who would know how or where to test for KHV in Australia.


                            • #15

                              yes maybe your right/..
