Book Description
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.

Book Description
Excerpt from Seasonal Abundance and Distribution of Zooplankton, Fish Eggs, and Fish Larvae in the Eastern Gulf of Mexico, 1972-1974 Identification of organisms was limited to the broad categories of zooplankton, fish eggs, and fish larvae. Thus, our results were used only in a relative sense. To define areas of high or low productivity on the western Florida shelf. The eggs and larvae of clupeid fishes were identified and future papers will describe their distribution and abundance, as well as estimates of stock abundance based on them (houde in press). Results published here will be useful when considering possible effects of man's activities in theeastern Gulf of Mexico. Because the area has important commercial fisheries and is presently a focus of oil explora tion. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
