Zooplankton volumes and abundance of fish eggs and fish larvae were determined for stations on 12 cruises to the western Florida continental shelf. Contour charts of zooplankton volumes and of ichthyoplankton abundance are presented. A marked seasonality was observed for zooplankton and ichthyoplankton, highest zooplankton volumes and ichthyoplankton abundance occurring during May through September. Zooplankton volumes were highest and spawning by fishes most intense in the northern half of the study area (north of lat. 27°15ʹN). Fish larvae abundance (number under 10 m2 of sea surface) was highest at stations deeper than 50 m. Simple correlations among biological variables showed fish egg abundance-zooplankton volumes and fish egg abundance-fish larvae abundance to be positively correlated on most cruises. No clear relationships were observed between abundance or concentration of biological variables and temperature or salinity.

The best and most expensive caviar uses eggs from sturgeons caught in the Caspian Sea. But eggs from many other fish species have been used to develop products imitating original caviar. By utilizing processes appropriate for each kind of fish, it is possible to make a similar, though imitation, product. This publication presents an overview of the production of lumpfish eggs as a model for developing fish caviar. It describes fishing methods, preservation and storage of the eggs, as well as details on the caviar production process itself to obtain the final product. Production and marketing statistics demonstrate the extent of the global lumpfish caviar business. The publication draws heavily on source material from Iceland.
