You now have a list of all the species codes that eLandings currently accepts. This approach can be used to load statareas, gear codes, chill types, etc. Typically, eLandings creates a resource jar file containing all of the lookup code files. These code files can then be bundled with a release.
Be aware that every year, a few minor changes are made to these code files. For example, once a year, a new species might be added or modified within the species.xml file.
