Residency and movement patterns of bonnethead sharks, Sphyrna tiburo, in a large Florida estuary
The use of a coastal estuary by bonnethead sharks, Sphyrna tiburo, was examined by acoustic monitoring, gillnet sampling and tag- recapture studies. Acoustic monitoring data were used to define the
Variation in the performance of acoustic receivers and its implication for positioning algorithms in a riverine setting
The performance of an array of data-logging single frequency acoustic receivers in the Caloosahatchee River (Florida, USA) was examined and the results incorporated into a positioning algorithm for
Hard prey specialists or opportunistic generalists? An examination of the diet of the cownose ray, Rhinoptera bonasus
TLDR
Although R. bonasus has been characterised as a hard prey specialist, these results suggest it may behave as an opportunistic generalist, modifying feeding behaviour to consume readily available prey.
Residence and movement patterns of cownose rays Rhinoptera bonasus within a south‐west Florida estuary
TLDR
Data show that cownose rays travel extensively throughout this estuary, yet may remain within very small areas for extended periods, as mobile, pelagic swimmers capable of traversing large distances.
Spatial Distribution and Long-term Movement Patterns of Cownose Rays Rhinoptera bonasus Within an Estuarine River
Passive acoustic telemetry was used to monitor the movements of cownose rays (Rhinoptera bonasus) within the Caloosahatchee River estuary in Southwest Florida. Twelve rays were tracked within the
Long-term presence and movement patterns of juvenile bull sharks, Carcharhinus leucas, in an estuarine river system
TLDR
Long-term consistent use of this habitat by young C. leucas suggests this population is highly dependent on the Caloosahatchee River as a nursery area, suggesting further diurnal patterns in habitat use.
Partial migration of the nurse shark, Ginglymostoma cirratum (Bonnaterre), from the Dry Tortugas Islands
TLDR
Some overwintered and some resumed courtship in June, demonstrating both resident and migratory contingents within their population, partial migration and an ability to navigate with high spatial and temporal precision.
An investigation into the habitat, behavior and opportunistic feeding strategies of the protected goliath grouper (epinephelus itajara)
TLDR
This study studies the distribution and habits of Atlantic Goliath Grouper Epinephelus itajara in the eastern Gulf of Mexico and finds abundance, size distribution, and habitat association are regulated by conventional tagging methods.
A preliminary assessment of the abundance and size distribution of goliath grouper Epinephelus itajara within a defined region of the central eastern Gulf of Mexico
Fishing for goliath grouper was banned in United States waters in 1990 after a noted dramatic decline in population numbers. After eighteen years of protection, the species is reportedly showing
Variations in reproductive potential between nearshore and offshore spawning contingents of hogfish in the eastern Gulf of Mexico
TLDR
Spatial variations in size coincide with ontogeny because hogfish move offshore with growth; however, even after accounting for fish size, offshore females spawned more than nearshore females, and batch fecundity was related in a log-linear manner to female size.
