4 Technical Presentation Florida s Non-Native Fish: An Overview Presented by Katie Lawson

5 Non-native fishes in Florida Katelyn M Lawson and Jeffrey E Hill

6 Accidental: Ballast water/fouling Escape off farms Bait bucket How did they get here? Intentional: Aquarium/food fish release Sportfish stocking/movement by anglers Cultural importance Human use is behind most of these vectors.

7 Are they all bad? Negative effects Ecological: predation, competition, habitat alteration Economic: agricultural pests, fisheries impacts, industry Social: nuisance, human health effects Positive effects Economic: ornamental trade, food fish, sport fishing, weed control Social: sport fishing, aquarium pets

8 Why so many non-native fish in Florida? Large human population Lots of travel and commerce Pet trade/ornamental industry Favorable climate Diverse habitat, much of it disturbed Relatively depauperate fauna for the southeast

9 Are they all invasive? Introduction Successful reproduction & recruitment Establishment of stable population Spread Impacts

10 Where are most of these fish? 4 Exotic species established Ex) Common carp, Blue Tilapia 10 Transplant species established Ex) Flathead catfish 20 Exotic species established Ex) Pike killifish, Plecos 5 Transplant species established Ex) Gizzard shad 30 Exotic species established Ex) Bullseye snakehead 2 Transplant species established Ex) Rio Grande Cichlid

11 North Florida Many rivers from Alabama and Georgia draining into panhandle Native fish fauna more diverse than in the rest of Florida Flathead Catfish Pylodictis olivaris Transplanted into rivers in panhandle Can grow to 120 lbs Its predation on native bullheads and sunfishes are leading to declines in those species

12 Central Florida: Tampa Bay area Ornamental fish industry in this part of the state Jack Dempsey Rocio octofasciata Green swordtail Xiphophorus hellerii Southern Platy Xiphophorus maculatus All three have disjunct populations that do not spread; some appear to be stable. Mayan Cichlid Pike Killifish

13 Central Florida Swamp Eel Monopterus albus Walking Catfish Clarias batrachus Extreme adaptations: Air breathers Burrow to survive drought Can survive months w/o food Protogynous hermaphrodites Can infest fish farms: Eat fish, not voracious though First observed in 1960s walks during rainy weather Predatory Makes the news sometimes Can infest fish farms: Eat fish, not voracious though Spines are traumatogenic

14 South Florida Bullseye Snakehead Channa marulius Oscar Astronotus ocellatus Only in canals of Broward Co. Spread is a concern, especially into Okeechobee Predatory Looks similar to native bowfin: Popular aquarium fish Grows large and likely to be released Predatory Many color variants in trade Notoriously difficult to electroshock

15 South Florida Butterfly Peacock Bass Cichla ocellaris Spotted Tilapia Tilapia mariae Intentionally stocked in S. Florida canals by FWC in 1964 Spread is cold-limited Important recreational fishery Does not compete with bass Parental care Does eat spotted tilapia Farm escapement/aquarium release potential vectors Benthic herbivore Bi-parental care Common in S. Florida canals More aggressive than native sunfish

16 Extreme spreaders: state-wide species Sailfin Catfishes Pterygoplichthys sp. Brown Hoplo Hoplosternum littorale Four species, hard to distinguish Air breathers Herbivorous Popular aquarium fish (plecos) Have demonstrated impacts Munching on manatees Burrowing causes erosion Fouling of commercial fishing nets First observed in 1995 Has very rapidly spread throughout much of the state Bubble nester Air breather, benthic scavenger Popular food fish in South America

17 Extreme spreaders: state-wide species Blue Tilapia Oreochromis aureus African Jewelfish Hemichromis letourneuxi Many pathways of introduction Important food fish for aquaculture, commercial fishery Here since the 1960s Mouthbrooder Alter habitat by nest building May compete for spawning sites First observed in 1965 in S. Florida Spread into central Florida Smallest non-native cichlid here Very high salinity tolerance Requires lots of vegetation Some impacts on natives

18 Take home Non-natives have both costs and benefits Invasion is a complex process Small proportion of those introduced become invasive Most impacts are on a local scale Most non-natives are located in South Florida Considerable variety of fishes established
