Title:
Hydroacoustic Biomass Assessment of Reef Fish Spawning Aggregations in Western Puerto Rico (CRCP ID# 1242-05/06/07).
Geospatial_Data_Presentation_Form: map, spreadsheet
Abstract:
The data set consists of two products. The first product are maps that represent fish average densities collected by active hydroacoustic survey technique in the water column along a transect for each monthly sample. These data are also compiled by location by year. The fish density data is plotted over a bathymetric map. The second product are Excel spreadsheets with a summary of the integration of fish echoes over a sampling period that is used to produce the first product by location.
Purpose:
The purpose for which these data were collected was to help find areas of high fish density within a coral reef environment. Other reasons to collect the data was to help locate reef fish spawning aggregation sites, obtain target strength values for different reef fish species and determine size frequency distribution of some of these species.
