Geomorphic characterization of reef fish aggregation sites in the Upper Florida Keys
"The objective of this study was to determine if multiple reef fish aggregation sites in the upper Florida Keys share characteristic geomorphic features. A commercial single-beam acoustic seabed classification system was used to map the seabed in the vici...
Coral reef fish assemblage shifts and declines in Biscayne National Park, Florida, USA
"Reef fish assemblage structure was assessed in 2006-2007 ("recent" period) in Biscayne National Park, Florida, USA , and compared with data collected from 1977 to 1981 ("historical" period) from the same location. Substantial differences were observed in...
2006 Marine nurseries and effective juvenile habitats: Reply to comment
"We were encouraged to see the Comment by Sheaves et al. (2006, this volume) regarding the Effective Juvenile Habitat (EJH) concept (Dahlgren et al. 2006). Our intention was to provoke discussion on the juvenile habitat evaluation model proposed by Beck e...
"Similar to nearshore systems in temperate latitudes, the nursery paradigm for tropical back-reef systems is that they provide a habitat for juveniles of species that subsequently make ontogenetic shifts to adult populations on coral reefs (we refer to th...
Patterns of juvenile habitat use and seasonality of settlement by permit, Trachinotus falcatus
"Permit, Trachinotus falcatus are economically and ecologically important throughout their range of the Caribbean, subtropical and tropical western Atlantic, and Gulf of Mexico. Despite their economic importance, little is known about the biology and ecol...
Marine nurseries and effective juvenile habitats: Concepts and applications
"Much recent attention has been focused on juvenile fish and invertebrate habitat use, particularly defining and identifying marine nurseries. The most significant advancement in this area has been the development of a standardized framework for assessing...
Acoustic signatures of the seafloor: Tools for predicting grouper habitat
Groupers are important components of commercial and recreational fisheries. Current methods of diver-based grouper census surveys could potentially benefit from development of remotely sensed methods of seabed classification. The goal of the present study...
"Recent reports have raised serious concerns about the rapid declines of historically productive marine fishery resources and the degradation of essential fish habitats. This global crisis has spurred development of innovative management strategies to reb...
Detecting fish aggregations from reef habitats mapped with high resolution side scan sonar imagery
As part of a multibeam and side scan sonar (SSS) benthic survey of the Marine Conservation District (MCD) south of St. Thomas, USVI and the seasonal closed areas in St. CroixLang Bank (LB) for red hind (Epinephelus guttatus) and the Mutton Snapper (MS) (L...
Analysis of hydroacoustic data for large reef fish targets in Puerto Rico
"This report summarizes the findings and outcomes of an in-depth analysis of the 2002 and 2003 Red Hind Hydroacoustic Surveys datasets. Hydroacoustic survey datasets were originally analyzed for the presence, distribution and density of fish aggregations ...
