Quantifying the Accuracy of Shark Bycatch Estimations in Tuna Purse Seine Fisheries

Scientists were strategically positioned during fishing sets in order to establish a reference count of captured sharks during commercial fishing trips and compared them to observer and electronic monitoring counts in the Pacific.

Ensemble Random Forests as a Tool for Modeling Rare Occurrences

Through simulation, we show that ERFs outperform Random Forest with and without down-sampling, as well as with the synthetic minority over-sampling technique, for highly class imbalanced to balanced datasets.

Abundance of Neglected Fishing Gear in the Hawaii-Based Pelagic Longline Fishery Grounds

We study the abundance of derelict fishing gear (DFG) accumulating in zones coinciding with the fishing grounds of the Hawai’i-based pelagic longline fishery with results that suggest that the relative abundance of DFG has declined ~66% from 2008–2016.

On-Board Study of Gas Embolism in Marine Turtles Caught in Bottom Trawl Fisheries in the Atlantic Ocean

This study looks at decompression sickness in marine turtles after incidental capture in trawl gear, and provides estimates of on-board and post-release mortality.
