Impact Scores for 32 Nonnative Freshwater Fishes in Peninsular Florida

32 nonnative freshwater fish species established in Peninsular Florida are assessed using a modified Generic Impact Scoring System (GISS). The dataset, created by Katelyn M. Lawson and last updated in April 2026, includes impact scores and associated life history traits to predict ecological impacts. Results indicate less than 20% of assessed fishes had moderate impact scores, with none scoring as high impact.

Use Cases

• Predicting ecological impact severity based on life history traits like swim factor and parental care.
• Prioritizing management efforts for nonnative fish species using standardized impact scores.
• Comparing the relative impacts of invasive freshwater fishes across different geographic regions.
• Training models to identify traits associated with higher impact scores for risk screening.

Strengths

• Applies a standardized impact assessment framework (modified GISS) to 32 species.
• Links impact scores to specific life history traits for predictive analysis.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and specific column-level documentation are unknown.
• The dataset is small (86.2 KB), limiting its scope to 32 assessed species.
• Geographic coverage is restricted to Peninsular Florida.
