| Abstract | Micronekton are relatively small but actively swimming organisms ranging in size between plankton (< 2 cm), which drift with the currents, and larger nekton (> 10 cm), which have the ability to swim freely without being overly affected by currents. Although there are some precise definitions based on Reynolds numbers, micronekton may be operationally defined as taxa too vagile to be caught with conventional plankton nets and too small to be retained by most large-meshed trawls. Micronekton are diverse taxonomically. The principal groups include the cephalopods (small species and juvenile stages of large oceanic species), crustaceans (including adult euphausiids, pelagic decapods and mysids), and fishes (mainly mesopelagic species and juveniles of pelagic nekton). Although not generally fished commercially because of their relatively small size and high lipid content, mesopelagic fishes represent a substantial biomass in oceanic waters and are a critical but poorly understood intermediate trophic link between the mesozooplankton and the higher trophic levels including fishes, seabirds and marine mammals. Many studies have shown that micronektonic species are a primary food source for a wide variety of harvested nektonic species. |
