Which outcome negatively impacts coastal fisheries during rapid thermocline deepening?

💡 Explanation

Reduced nutrient transfer arises because a deeper thermocline limits wind-driven upwelling. Consequently, this restricts nutrient delivery to surface waters, therefore hindering phytoplankton growth. This harms the food chain rather than promoting blooms, deepening the mixed layer, or raising oxygen levels.
