Invasion frustration? Can biotic resistance explain the small geographic range of non-native croaking gourami Trichopsis vittata (Cuvier, 1831) in Florida, USA? In this report, we evaluate this hypothesis for croaking gourami Trichopsis vittata, a non-native species that has established a reproducing population, but has not successfully spread beyond its very small (5 km2) range. We suspected the inability of T. vittata to colonize new habitats may be due to biotic resistance by the native eastern mosquitofish Gambusia holbrooki.

Herein, we report sightings of 41 species from Florida coastal waters since the earliest sighting in 1984.

Herein we report the eradication of two species of non-native fishes in Miami, Florida (Giant Cichlid Petenia splendida and Blue Mbuna Labeotropheus fuelleborni; both Family: Cichlidae). We removed these fishes before they were observed in the extensive, interconnected canal system through which they may have been able to expand throughout south Florida and access protected areas such as Everglades National Park and Water Conservation Areas. Categories: Data; Tags: Aquatic Biology, Southern Florida, USGS Science Data Catalog (SDC), biota, nonindigenous species Observations of bullseye snakehead (Channa marulius) in Florida This dataset contains information on the Bullseye Snakehead fish found only in southeastern Florida. It is a subset of a larger database, the Nonindigenous Aquatic Species Database (NAS). This information resource is an established central repository for spatially referenced biogeographic accounts of introduced aquatic species. The NAS website provides scientific reports, online/real-time queries, spatial data sets, distribution maps, fact sheets, and general information.

The strategy works by manipulating the sex ratio of a population through the introduction of supermales that guarantee male offspring. Categories: Data; Tags: Ecology, Gainesville, USGS Science Data Catalog (SDC), nonindigenous species Non-native Asian swamp eel, Monopterus albus/javanensis (Zuiew, 1973/Lacepede, 1800), responses to low temperatures Asian swamp eel, Monopterus albus/javanensis [Zuiew, 1973/Lacepede, 1800], has been established in the southeastern USA since at least 1994, yet little is known about its ability to survive low winter temperatures. We use standard thermal methodologies to quantify low-temperature responses and provide a detailed description of swamp eel reactions to cold temperatures. When exposed to chronic temperature decreases of 1.0 C per day, swamp eels ceased foraging at 15.0 C, markedly diminished movements below 11.0 C, and became incapacitated near 9.6 C. During critical thermal minima (CTmin) trials, swamp eels exposed to acute temperature drops (0.25 C per minute) tolerated temperatures as low as 6.2 C. Swamp eels exhibited...

Herein I report on the use of tools that have been used in Florida over the past seven years to assist with tracking of non-native fishes. Ten Fish Slams, where professional biologists and graduate students come together to sample an area for non-native fish, have been held since 2012, which have included nearly 100 individuals from 20 organizations. Participants have sampled nearly 200 unique sites, capturing 36 non-native fish taxa. These activities have generated over 600 records for the U.S. Geological...
