Marine habitats and fisheries: Habitats that are especially valuable for commercially harvested species (nursery and feeding grounds) are called what? Think of shallow coastal ecosystems supporting fish, shellfish, and invertebrates. Choose the correct term.

Given data

• Asks for the specific habitat known for supporting commercial fishery species.

Concept/Approach
Seagrass beds (underwater flowering plants) are critical nurseries and feeding grounds for many commercially harvested fish and invertebrates. Coral reefs are also biodiverse, but the canonical GK answer for such nursery habitats tied to harvested species is seagrass beds. 'Hot spots' refers to biodiversity hotspots, not a habitat type.

Final Answer
Sea grass bed
