Source identification list

Implementing a consistent model on exact and accurate genealogy management requires more than a simple species identification process. Even a perfect method to assure a strict idea of species will never be effective to deal with a population or pedigree, even thinking on elementary basis.

For some populations and heredity continued existence or to safeguard biodiversity, unbreakable chain of evolution can be of crucial importance.

Otherwise mixing individuals of isolated small populations can represent the rescue of its kind, allowing this way to avoid or fight genetic problems in small populations or simply guarantee a stock viability.

This is a very important resource in metapopulations managing.

In both circumstances, without a simple way of information concerning original derivation or past contributions to actual genetic inheritance, it would be impossible to act securely and with perfect understanding while administrating fish diminutive stocks.

Almost certainly, soon ahead new modus operandi will be developed and other solutions tried out during make of use.

However the preliminary method is based in only two numbers.

00 represents all uncertain source of population. Especially aquarium raised lineage with unknown or unclassified foundation will be catalogued on his category. This can result either from lost of control over base stock information about or from mixed ancestry.

All other alternatives are classified according location type or precise origin in the wild regarding some information like :

• Fish water body or hydrographical basin ancestry. It can also include other important data similar to Federal State, Province, municipality or nearest locality.

• Country

• Geographical coordinates ( optionally )

Each location will be recorded under a single number and the list is updated when needed.

When crucial the country names are placed in Portuguese and English.

Next figure is an example of this section.
