Export of PUFA via emerging aquatic insects was studied in a midsize lake.
- class="label">•
Aquatic insects contained high concentrations of essential PUFA.
- class="label">•
In total, 80.5 mg PUFA were exported per square meter and year.
- class="label">•
Chironomidae contributed most to total PUFA export.
- class="label">•
Chaoborus contributed most to the export of EPA, ARA, and especially DHA.
