E.D. Houde, in Encyclopedia of Ocean Sciences (Second Edition), Fish Larvae and Plankton. Larvae of marine fishes, termed ichthyoplankton, usually are pelagic, drifting in the sea and interacting with pelagic predators and planktonic fish larvae, even of species that ultimately are herbivores as juveniles or adults, are primarily carnivorous during the larval stage, feeding. Ichthyoplankton Identification Experts The Fisheries Resources Division houses one of the foremost ichthyoplankton ID laboratories in the world. Researchers visit from around the globe to look at the collection, to verify or compare their samples with ours, and to receive training on ichthyoplankton identification from our world class experts. Ichthyoplankton are the eggs and larvae of fish found mainly in the upper meters of the water column, also called the near-surface waters. The eggs are passive and drift in the ocean along with the water currents. Most fish larvae have almost no swimming ability initially, however by half way through their development they are active swimmers.

The density of eggs or larvae was calculated by N = X.v-1, where N is the number of eggs or larvae per m 3, X the number of individuals at the sampling station, and v the volume of filtered water. The water volume v was obtained by v = a.n.c, where a = area of. The Offshore Zooplankton and Ichthyoplankton Characterization Plan is an effort to collect data that will be used to describe the plankton assemblage in the northern Gulf of Mexico (GOM) and to inform the evaluation of potential impacts from the Deepwater Horizon Oil Spill (DHOS) to the zooplankton and ichthyoplankton in the region.

Ichthyoplankton were taken horizontally and vertically. It is sampled with WP2 type plankton net, 57 cm frame diameter, µm mesh size and cm long. These samples were preserved 4% borax. The current SEAMAP ichthyoplankton survey is based on collections made with a bongo net fitted with mm mesh nets. However, the previously cited work of Houde and Lovdal () and Comyns () from the Gulf of Mexico indicated that a plankton net mesh size of mm may be more efficient at collecting small by: 9. During Italian expeditions, ichthyoplankton was collected in the Ross Sea and Terra Nova Bay, by BIONESS and Hamburg Plankton Net (µm and µm mesh, respectively). A total of , fish larvae representing 46 species, 27 genera and 9 families were collected.
