The bycatch often does not survive the pressure and temperature differences when hauled in.

The fishery on escolar is not managed, in part because of the lack of a reliable stock-assessmentStock assessment:
Based on data about fish catch of fishermen and samples conducted with research vessels, a stock assessment describes the current and former status of a fishery stock. The size of the stock will be measured and a prediction will be made about how the stock will respond to management measures..
