Aor is a top view ranchu line-breeder. He uses the same method for creating and maintaining ranchu bloodline, as it is done in Japan. Line-breeding is when animals are selectively bread for desired features by mating closely related individuals. Over time this creates a bloodline with breeder's desired characteristics. This method requires great dedication and skill. Bloodlines can be line-bred for decades to continually improve and develop characteristics that sets them apart. On occasion, line-breeders will introduce ranchu from a different, but often related bloodline to boost vigor and to minimize the negative effects of inbreeding. 

Over six years that Aor has been involved with ranchu, he has achieved a tremendous success and respect among ranchu keepers and breeders in Thailand, as well as Japan, Singapore, Taiwan and here in the USA. 

We were visiting Aor after his big sale, when most of his 2 month old CBR were already sold and waited to be picked up or shipped. 

BBR are growing fast. All are almost perfect at this stage!

A couple of tubs were housing Aor's potential seed ranchu, selected from this year's spawn. They are CBR of 2.5 month of age. Please observe beautiful proportions of these promising, but still very young ranchu.

Aor's future seed CBR

Given Bangkok's hot tropical climate, with an average year round day temperatures lingering over 91 F (33 C) and night temperatures often above 74 F (23 C), ranchu develop very fast. They reach their sexual maturity quick, with their life span extending three to four years. 

Based on Aor's answers below, he goes on average through 45,000 fish each year to continue working on his bloodline. This requires very hard work, thus Aor's family is involved in this venture as much as he is. Being able to process and cull through such quantity of ranchu is only a part of success. The masterful grooming complets the cycle. Even a perfect BBR can be ruined by improper  techniques. Swim too much and the tail is gone, eat not enough and the ranchu goes undeveloped, etc. And the most challenging part of all is that you must improvise based on what you have. It is never set in stone, all techniques serve only as guidelines.

Aor employs breeding and grooming techniques suitable for his location. Here are some Q&A with Aor regarding his breeding methods and ranchu quality:

Q: How many spawns do you collect per year?
A: Three times a year, each time 4-5 batches.

Q: How often do you cull?
A: Every time I do water change.

Q: What is an outcome from one of your average spawns? How many final keepers do you end up with on average?
A: Approximately 10 fishes from one batch of 2000-3000 fishes.

Q: Do you hand spawn?
A: Yes, only hand spawn. Usually one female with one male.

Q: How often do you introduce seed ranchu from other breeders to continue working on your line?
A: Not often, only to prevent inbreed, because I use line breeding system.

Q: What is the main characteristic(s) of your line of ranchu that sets them apart?
A: When I cull, I focus on the balance of my fishes.

Q: What are the main qualities that you try to preserve or develop in your future ranchu?
A: I intend to develop tail structure to be stronger, because temperature in Thailand makes them more active and swim a lot.

Q: How many times have you won ranchu competitions and in what categories?
A: I won many times various categories from every club in Thailand. Two consecutive years, 2012 and 2013, best in show at the Siam Ranchu Club, and #1 ranking in Thailand for 2012 - are my remarkable prizes that I am proudly presented with.

Q: What suggestion(s) will you give to a beginner ranchu keeper?
A: You need to understand basic needs of ranchu such as container, water, food and air.

Q: Do you have the ability to sell/ship your ranchu internationally?
A: Yes, I can ship my ranchu almost everywhere. Although, please check custom procedures for your country.

Here are some of Aor's older ranchu. At the time of our visit he had no oya left. I was happy to hear that his 8 inch (19-20 cm) oya! were sold to a ranchu connoisseur.

I will always remember this visit to Aor. What a guy, what a fish, what a visit!
