The DNR is SC has a three letter identification system for fish, as well as all the other animals and plants found in the state. THis system uses the common names though instead of the binomial to abbreviate. It is complex and not always logical. I'm not sure if this is standard practice in other states or not or if the system is universal. It makes keeping track of what you have in the field easier and faster.
In Louisiana we use a number system for species that is probably more complex and illogical. When in the field, I just write down species names, and sort out the codes on a rainy day in the office.

You may also see references to trinomials, which just means that some further subdivision beyond species is recognized (in animals, the only lower division is the subspecies, but it's more complicated with plants). If a species is divided into subspecies, one is designated the nominate subspecies and its subspecific epithet is the same as the specific epithet. Let's say you studied variation in the flathead and decided it should be divided into eastern and western subspecies. Then, you must determine which subspecies the type specimen belongs to, and that one will be the nominate subspecies, Pylodictis olivaris olivaris. Then you must choose a different name to apply to the remaining subspecies.
