Temperature and Hypoxia Tolerance of Selected Fishes from a Hyperthermal Rockpool in the Dry Tortugas, with Notes on Diversity And Behavior

摘要

We documented the physical habitat characteristics and fish diversity of a hyperthermal rockpool on Loggerhead Key in the Dry Tortugas National Park during July 2000. Rockpool temperatures ranged form 30.5 deg. C to 35.8 deg. C and oxygen varied form 6.4 to 3.5 mg/L depending on depth and time of day. Seven fish species from five families inhabited the rockpool.
