Elasmobranchs living in rivers and estuaries may be highly susceptible to environmental and anthropogenic changes to coastal habitats. To address this, patterns of movement of 67 juvenile bull sharks (Carcharhinus leucas) were examined in the Caloosahatchee River between 2003 and 2006 using an array of 25 acoustic receivers. Individuals were monitored for periods of 1–460 days with most present for periods of weeks to months. Individuals utilised the entire monitored section of the river (∼27… 

Figures and Tables from this paper

Long-term patterns of abundance, residency and movements of bull sharks (Carcharhinus leucas) in Sydney Harbour, Australia
TLDR
Water temperature was the key predictor for seasonal movements and return behaviour to this estuary, suggesting that increasing water temperatures as a result of climate change may lead to higher shark abundance and possibly longer periods of residency in Sydney Harbour.
Residency Patterns and Migration Dynamics of Adult Bull Sharks (Carcharhinus leucas) on the East Coast of Southern Africa
TLDR
The residency patterns and migration dynamics of 18 adult bull sharks tagged in southern Mozambique suggest that effective conservation strategies for this vulnerable species necessitate the incorporation of congruent trans-boundary policies over large spatial scales.
Nearshore movement ecology of a medium-bodied shark, the creek whaler Carcharhinus fitzroyensis
TLDR
The movement patterns exhibited by C. fitzroyensis suggest that this species has a moderately high degree of seagrass habitat specialisation, which may be an important foraging habitat for this species.
Habitat use and movement patterns of bull sharks Carcharhinus leucas determined using pop-up satellite archival tags.
TLDR
While some individuals made large-scale movements over open ocean areas, the results emphasize the importance of the coastal zone for this species as potential essential habitat, particularly in areas of high freshwater inflow.
Environmental Influences on the Spatial Ecology of Juvenile Smalltooth Sawfish (Pristis pectinata): Results from Acoustic Monitoring
TLDR
Salinity electivity analysis demonstrated an affinity for salinities between 18 and at least 24 psu, suggesting movements are likely made in part, to remain within this range, although it remains unclear whether or not these movements are threatening recovery.
Distribution and Dynamic Habitat Use of Young Bull Sharks Carcharhinus leucas in a Highly Stratified Northern Gulf of Mexico Estuary
TLDR
It is suggested that future studies coupling telemetry and hydrographic variables should, when possible, consider the interactions of multiple environmental parameters when defining the dynamic factors explaining the spatial distribution of coastal sharks.
Ontogenetic shifts in movement and habitat use of juvenile pigeye sharks Carcharhinus amboinensis in a tropical nearshore region
TLDR
By defining transitions in habitat use behaviour among juvenile sharks, this study provides a better understanding of the implications associated with coastal shark species of multiple age classes using a shared environment.
Abundance, habitat use and movement patterns of the shovelnose guitarfish (Rhinobatos productus) in a restored southern California estuary
TLDR
The structure and functionality of a restored estuary is examined and it is suggested that the FTB is important habitat for a benthic predator, a promising result three years after restoration.
Regional-Scale Migrations and Habitat Use of Juvenile Lemon Sharks (Negaprion brevirostris) in the US South Atlantic
TLDR
The findings validate the existing multi-state management strategies now in place and affirm the value of collaborative passive arrays for resolving seasonal movements and habitat preferences of migratory coastal shark species not easily studied with other tagging techniques.
Riding the tide: estuarine movements of a sciaenid fish, Argyrosomus japonicus
TLDR
The findings suggest that juvenile A. japonicus adopt 2 distinct feeding strategies within their turbid estuarine nursery habitats, which may help them fulfil their foraging requirements by feeding on stationary and/or passing prey, while at the same time reducing predation risk in sheltered, structured habitats.

Movement and distribution of young bull sharks Carcharhinus leucas in a variable estuarine environment
TLDR
Since bull sharks are euryhaline, results suggest that they may select environmental conditions via movement, possibly to reduce energetic costs associated with osmoregulation.

Occurrence, home range and movement patterns of juvenile bull (Carcharhinus leucas) and lemon (Negaprion brevirostris) sharks within a Florida estuary
TLDR
Watching the long-term movements of large juvenile bull and lemon sharks in Pine Island Sound suggests that estuarine coastal lagoons provide an important habitat for this portion of their life history and as such, protection of these habitats may assist in shark management and conservation.

Distribution and habitat partitioning of immature bull sharks (Carcharhinus leucas) in a Southwest Florida estuary
TLDR
The distribution and salinity preference of immature bull sharks were examined based on the results of longline surveys in three adjacent estuarine habitats in southwest Florida indicating the occurrence of size-based habitat partitioning.

TLDR
Results demonstrate the utility of the Everglades National Park for the conservation and management of elasmobranch species and the need to consider how future changes to the environment will affect this important group of predators.

TLDR
The distribution of ocean inlets and salinity appear to be major factors affecting diversity and numbers of elasmobranchs in the Indian River system.
