An Updated Population Viability Model for Smalltooth Sawfish for the Northwest Atlantic incorporating improved estimates of Bycatch for the Southeast Shrimp Trawl Fishery and a large-scale Mortality Event from Toxins from Harmful Algal Blooms

An age-structured Leslie matrix model previously developed for the US population of smalltooth sawfish, Pristis pectinata, was updated to determine their ability to recover under new scenarios of bycatch from the US southeast shrimp trawl fishery. Additionally, the model considered a large-scale mortality event in 2024, which killed many large juveniles and adults.
