New Heating System in Grow-out Greenhouse, Part 2

Friday, October 30th, 2009

Whereas the last post described how we are now heating the water in our Grow-out Greenhouse, this post will describe how we are heating the air.  The primary purpose of also heating the air is to keep the air about two degrees warmer than the water so that we won’t have condensation continually forming on the inside roof of the greenhouse.  In order to accomplish this we will utilize a similar method as to how we are heating the water.  Hot water produced from our boilers will be carried through copper plumbing and up to a Modine heater suspended from a metal greenhouse bow.  The hot water will flow through the heater and a fan will blow the warm air across the greenhouse.

Quality Koi in Florida

Friday, October 30th, 2009

Quality Koi is on the road at a koi show this weekend.  Mat flew out early this morning to Delray Beach, Florida.  There are two koi clubs hosting this koi show, ZNA Southern Koi Association and the Tropical Koi Club.  The show is at Morikami Museum and Japanese Gardens.  For more information you can visit our Events Page.

Next weekend Mat will head down to Charlotte, North Carolina for the koi show hosted by Piedmont Koi and Watergarden Society.  If you will be at the show and are looking for something specific, just let us know and we will work to find the right koi for you.

New Heating System in Grow-out Greenhouse, Part 1

Wednesday, October 28th, 2009

In an earlier post, I started to discuss the filtration aspect of our new Grow-out Greenhouse.  This post will begin to discuss our new indirect heating system that is currently being installed in the greenhouse.  The purpose of the Grow-out Greenhouse is to increase the length and mass of our smaller high-grade koi.

The majority of our other greenhouses have heating systems where propane is utilized to heat the air and subsequently heat the water.  There are many inherent problems with this system, the largest one being inefficiency.  Since heat rises, much of the heat escapes through the roof.  Also, when the heat is raised to 78 degrees the water only reaches 65-66 degrees.  At this temperature koi will not put on the size we are trying to achieve and we are not able to feed them a high protein food.

Our new indirect heating system utilizes six heat exchangers (one per system) and two boilers.  Each boiler is 150,000 BTU which is more efficient than one 300,000 BTU boiler because having two allows for stage firing.  The boilers are powered by propane to heat water.  This water travels through copper piping into the greenhouse.  We chose copper because the spanning between brackets is 5 feet, and copper won’t bow, buckle, or degrade in the sun.  The water in the copper will never come in contact with the koi (copper is toxic to koi).  The heated water is brought into a heat exchanger.  The heat exchanger is filled with many tubes, which are filled with the heated water.  The pond water also enters the heat exchanger, but it surrounds the outside of the tubes.  Through this indirect contact, the pond water is heated and brought back into the ponds through PVC plumbing.  In the picture of the heat exchanger you will not see the PVC plumbing, as that is one of the jobs to be done this week.

This system of indirect heating gets the water much warmer than it would if we were to heat the air.  Also, it provides a more consistent water temperature.  Each system will also have its own thermostat so that it can adjust the heat automatically should one system become cooler, such as during a water change.  We will now be able to heat the water to our ideal 76-78 degrees.

While the initial investment to setup this system is more expensive, the cost to operate it will be considerably less expensive due to its efficiency.

Koi Treatments While in Quarantine

Tuesday, October 27th, 2009

We take our quarantine procedures very seriously at Quality Koi Company, as koi health is always our top priority.  AtMain Event Harvest, all of the koi are brought into greenhouses.  They remain in mandatory quarantine until December 31.  Our quarantine consists of first bringing the koi into salted tanks and then letting them rest for about a week.  Our goal is to reduce the amount of stress they experience.  The process of being seined, transported, handled, netted, bowled, and moved puts the koi through stress.  We want them to have rested for about a week with no interference from us.  Any koi that is showing obvious signs of stress, injury, or infection is immediately removed, inspected, and treated appropriately. 

The first treatment we typically do is Potassium Permanganate, which turns the water a purplish color until it oxidizes.  This treatment is stressful for us since we can’t see the koifor a day or two!!  The primary purpose of this treatment is to remove the likelihood of costia infection.  When koi are handled and experience a change in water temperature, it is very common for costia to appear.  We do this treatment first as a preemptive way of handling potential costia.

The Guests that Just Won’t Leave

Monday, October 26th, 2009

Koi farms face all kinds of predators.  Over the years we have dealt with herons, otters, kingfishers, muskrats, ducks (you should see how many half inch koi they can swallow!), etc., but we are now facing one of our toughest challenges….RATS!!!  Ugh, yes, rats!!  We have always had cats around the farm that would help us keep our rodent populations down, but we noticed this spring that there were no cats anywhere on the farm, which in turn has lead to a huge rat population.  We didn’t realize how bad it had become until we started harvest clean-up.  Once the areas around our barn were landscaped we were able to see exactly how many holes were dug in the ground.  It seems as though there is a whole underground system the runs under our barn and even under one of the greenhouses.  We are using Hav-A-Hart traps, but we need something on a much larger scale.  There is always the prospect of using poison, but that can be a very scary prospect with having mudponds.  So our first round attempt at outsmarting the rats is  to trap them underground.  The area has been tilled and rolled (just like we do in our mudponds) today…we’ll let you know how it turns out…

How are you B.E.T.N.??

Wednesday, October 21st, 2009

We invite you to join us in the B.E.T.N. experience….Breeder’s Eye on Tategoi Nisai -

Harvest season marks the end of another koi season for most hobbyists. But for the breeder, this season comes to close at the same exact time the next season begins.  As koi are harvested from the mud ponds the breeder is examining each koi to see the progress made over the past 6 months in the mud ponds. During this evaluation the breeder is already deciding which fish should receive higher investment in terms of winter growing facilities.  These koi are kept in low stocked, heated, highly maintained greenhouses to obtain maximum potential during their time in the indoor concrete ponds. These special koi are called TATEGOI.

Take an educational journey with us over the next 12 months as we follow the development of these chosen Tategoi.  We are offering these koi to be purchased now from the “breeder’s harvest view.”  Over the next few months these koi will be reevaluated and their progress will be shared thru our blog.  At each evaluation the koi the may increase or decrease in price.

It’s your choice – Invest now for the lowest possible price for a Nisai Tategoi or wait for more information as the koi progress with supplied information ( pictures, text and video), BUT be prepared for those koi which remain Tategoi over the next year to increase in price! The koi will be taken off sale in May when the koi return to the mud ponds for the summer until they are harvested in the fall, at that point all bets are off until next fall.  So, how are you B.E.T.N.?

The koi are priced according to size:

30-34.5cm     $1,000

35-39.5cm     $1,500

40-45cm        $2,000

The photo of the koi was taken on harvest day, so you see what the breeder sees.

Price includes:
Growout Greenhouse Keeping until May 2010
Mud Pond Growing Fee from May 2010 – Fall 2010 Harvest
Greenhouse Quarantine for Fall 2010

Optional Annual Insurance Fee:
The Annual Insurance Fee is $300 which covers the koi until December 31, 2010.  The Annual Insurance covers ONLY death, damage, and/or deformity.  The Annual Insurance will provide the purchaser the ability to choose a new koi in the following year’s B.E.T.N.

All of these koi were determined to be female at their October 2009 harvest.  In the event that a sold koi is determined to be male prior to entering the mudpond in May 2010, the owner will have the option to choose a new koi of equal value from the remaining koi for sale in B.E.T.N.

Harvest Comes to a Close

Tuesday, October 20th, 2009

Well, harvest is over.  For the NKF staff, harvest began about two months ago with the tosai and nisai, which came at the end of a long and grueling breeding/growing/culling season.  Now the focus shifts to maintaining filtration and water quality in all of the greenhouses, and beginning our two month long quarantine process.  All of the Tategoi will be assessed and plans for who will be going to which mudpond begins.  Then we figure out which ponds will be used for breeding, which ones for growing, and potentially which breeding pairs will be spawned.  The harvest – breeding cycle is always in motion.

Thank you to everyone who braved the weather and came out to join us for Main Event!  We feel so very fortunate to have customers and friends who travel from as far as Canada, Florida, Illinois to be a part of harvest.  We especially want to thank our volunteers who were such a critical part of harvest…from landscaping to photography to milk runs to home cooked meals, thank you for all of your help…Steve Wernlund, Mike Frady, Verne Gilkes, Luke Frisbee, Dave Hicks, Mickey Stonepainter, Bob Brudd, Kavent and Dinah Bwint, Henry Culpepper, and Joyce Spears.

Some of our favorite moments from harvest…

Front Pond/Manic Monday Harvest

Monday, October 19th, 2009

We harvested the Front Pond this morning, which mostly consisted of last year’s Manic Monday koi.  Mat selected a variety of smaller nisai (concrete grown) and participants chose numbers out of a hat to determine the order in which they would select their koi.  After the koi were harvested today, Mat spoke about each koi, it’s development, and it’s probable future.  The koi he graded as Best Tategoi would receive free mud growing for next summer.  The winner is a Sanke that grew 21 cm (first picture posted)!!!  Most koi grew 12-20cm.

Main Event Harvest, Long Pond

Monday, October 19th, 2009

I know this post is a day late, thank you for being so patient!!  Harvest is just winding down here at the farm.  We had our last pull this morning (Front Pond, Manic Monday, I will post those next).  Below are the pictures from yesterday afternoon’s Long Pond.  The Long Pond is always for the largest koi.  We had it very lightly stocked this year with only 13 koi.  The extra space was beneficial given that we had a cooler summer this year.  Given the size of these girls, we snapped their photos in the 8′ show tank.  Hope you enjoy…

Thank you Kavent Bwint and Andy Hong for the photos!

555 Pond, Sold Koi

Sunday, October 18th, 2009

It was a great harvest this morning of the 555 pond!  Mat, Ross and the rest of the volunteers (Verne Gilkes, Mike Frady, Luke Frisbee, Dave Hicks) have had unprecedented success with each pond pull and 100% of the koi are caught in just one pull. 

Below are the sold koi from the 555 Event.  The guys are still at the farm photographing the unsold koi, so I won’t be able to post them until tomorrow.  55 koi were available for sale on May 5, 2009.  The event takes place online so that regardless of where you live, you are able to participate.  These koi were born in the summer of 2008 and all went out to the mudponds at 7-8 inches.  In May 2009 Mat assessed these Tategoi as females most likely, but as Tosai one can never be completely certain.  Based on his assessment today, a few did turn out male and there are a few that he is not yet certain of their sex.  We have been measuring our koi this harvest in centimeters (to convert centimeters to inches, divide the centimeters by 2.54).  Tomorrow on our website we will have a PDF showing the side-by-side comparison of the koi in May and now at their October harvest.  Thank you to everyone who participated!!

Each picture is labeled with it’s variety, event number, gender, and size.  We had to move through the photographing quickly today since we had a full harvest schedule so these photographs are not their “glamour” shots.  Thank you to Henry Culpepper and Kavent Bwint for all your help with the photography :)
