Skilled Vision Among Breeders
Historically, the best Pedigree Breeders always have and always will breed by eye. They are visual thinkers. Such breeders are often very instinctive and gifted with “Skilled Vision.”

Skilled Vision has been loosely defined as a learned practice
that allows for recognition and productive results. Based on powers of observation and acquired
knowledge, with far less proficiency in the language of science.
Successful breeders possess skilled vision to varying
degrees, and are able to develop a needed understanding of selection from hands
on experience. Good practice results
from recursive breedings made over time followed by evaluation of results. Incorporating skilled vision and practice in attempt
to control selection of genotype, while allowing for positive traits with reproducible
results in future generations. This is
the nature of Domestic Pedigree breeding.
Skilled vision can be viewed as a discipline involving
multiple sensory inputs. It has a
genetic basis, and is not simply the result of accrued knowledge &/or
environmental conditioning (formal education & training). Yet, skilled vision can be enhanced through
breeder communications, exchange of ideas, formal competitions, farm visits, breed
standards and scientific knowledge.

Is there a dichotomy between the art of breeding and science? Yes. While science can help a breeder understand results
and clearly communicate them to others, extensive reliance on science in
breedings can result in a loss of “balance” in results. This has been seen in many commercial breeds
over the last several decades.
Is there dichotomy between a successful breeder and his lessor peers? Yes. Those with skilled vision can take breedings to optimum levels of achievement and maintain them long-term.
Science allows me, as a breeder, to maintain a vast
array of phenotypes, with truly little effort, in a related breeding program through understanding of the sum total genotype. Knowledge of chromatophore interactions that determine color
& pattern; what is possible and what is not.

While maintaining a reference collection of nearly 5,000
scientific research papers, this falls short of the visual aids I routinely rely
on. In the form or nearly 70,000 photos
of guppies from personal breedings and that of others. To this you can add another 25,000
microscopy images made over the last 10 years.
My breeding notes are embarrassingly minimal and
rarely referenced in day to day practice.
Since childhood, sensory perception and visual analysis of the surrounding
environment has always been my preference.
Visual images often convey far more meaning than printed words. As a result, find little need to convert
images to words in my mind.
