Undocumented Species

Several species have been documented by previous researchers in the preserve, but we were unable to take them in our sampling. Loftus and Kushlan (1987) reported diamond killifish (Adinia xenica) and naked goby (Gobiosoma bosc) in the southern portion of BCNP. The survey of the Addition Lands administrative area by Dalyrymple (1995) included reports of chain pickerel (Esox niger) and channel catfish (Ictalurus punctatus) in the L-28 Canal. We repeatedly sampled for all of these species in likely habitats, but were unsuccessful. We conclude that these species are localized or rare in the preserve.

Based on their presence in nearby areas, it is also possible that threadfin shad (Dorosoma petenense), pirate perch (Aphredoderus sayanus), jaguar guapote (Cichlasoma managuense), and sailfin catfish (Pterygoplichthys spp.) may be found in the future in the preserve. A complete list of species likely to be found in BCNP is given in Appendix 2.

Based on our records and on previously documented species from the preserve, and compared with all potential species likely to be found there in the future, we estimate that we have documented 92 percent of the ichthyofauna of the preserve.
