Movements of a Non-indigenous Barbus barbus Population

Species: European barbel, Barbus barbus

Map View

European barbel (Barbus barbus) has one of the largest seasonal home ranges of all riverine fish and is an important recreational angler-caught species; hence it is an interesting and valuable study species (Ovidio et al 2007, Twine 2013). Analysis will focus at the individual level for the fish, initially determining their maximum distance travelled and total distance travelled, before analyses are completed in more depth in relation to diurnal and seasonal events, and winter flood events. Variability in movements will also be tested against sampling method (as angling tends to capture ‘bold’ individuals, i.e. those more likely to have high vagility) and stable isotope data (to identify if variability in movements has a trophic basis). There are also several potential barriers to movement within the study area which will be assessed for how they have affected home range and under which conditions they are passable.

OTN Arctic Cumberland Sound Array

Species: Arctic skate, Greenland halibut, Greenland shark, Ringed seal

Map View

Cumberland Sound, on southern Baffin Island, supports a wide variety and number of arctic fish, seabird and marine mammal species and a community of 1,400 people (Pangnirtung). Significant changes have occurred in the Cumberland Sound ecosystem in the recent past, which are likely due to climatic changes. Ice condition is the most obvious change as the duration of ice cover and the extent of land-fast ice have been reduced. These changes in arctic ice cover will likely have serious impacts on the trophic interactions and movements of arctic species. This project will target the spatial, seasonal and temporal interaction of fish and marine mammals in the Cumberland Sound ecosystem. This will be accomplished by overlying the spatial and temporal movements of key fish and marine mammal species using a combination of satellite tags, acoustic (V6) and chat tags, and an array of VR2W receivers in the Sound, with current and on going studies of trophic interactions using stomach contents and chemical tracers (stable isotopes) from numerous species and levels of the trophic system.

Species: Australian Bass, Sea Mullet, Freshwater Mullet

Map View

Dr. David T. Roberts and a team of researchers are conducting a study that aims to asses the ecohydrology requirements of key indicator fish species and assess if these requirements can be incorporated into environmental flow rules that govern water releases for the environment from weirs and dams on the river system.

Savannah River Sturgeon

Species: Shortnose sturgeon, Atlantic sturgeon

Map View

Jason Moak and his team are tracking movements of Shortnose and Atlantic sturgeon in the Savannah River.

Monitoring of Coastal Fish Populations

Species: Bass, Ballan Wrasse, Ray spp.

Map View

Greg Morel and his team are conducting monitoring and analysis of various important coastal fish species to assist with management of stocks and Marine Protected Area (MPA) design.

Tracking White Sharks and Various Coastal Fish Species

Species: White shark, Multiple coastal fish species

Map View

Enrico Gennari and his team at Oceans Research focuses on studies of coastal species of sharks, fish and marine mammals, including movement and behavioural modelling; population studies; and physio-ecological research.

White Sturgeon Supplementation Program

Species: White sturgeon

Map View

Corey Wright and his research team used Vemco tags and receivers to understand the emigration rates as well as behavior and movements of juvenile white sturgeon released in the Rocky Reach Reservoir on the Columbia River as part of a hatchery supplementation program.

Spatio-temporal Dynamics of Various Species

Species: Dusky kob, Spotted grunter, Bull (Zambezi) shark

Map View

Meaghen McCord and team conduct research to better understand inter- and intra-specific movement as a function of environmental and habitat in a heavily utilized estuary on the southwest coast of South Africa (Breede River).

Movement of Alligator Gar

Species: Alligator Gar

Map View

Kayla Kimmel and team are studying movement patterns, site fidelity, and spawning habitat of alligator gar that are being identified through ongoing telemetry, water quality, and satellite imagery within the Mississippi Alluvial Valley (on and near a National Wildlife Refuge).

Tracking Wrasses in Ría de Vigo

Species: Ballan wrasse

Map View

David Villegas Rios and his team are tracking the spatio-temporal behaviour of 25 individuals of Labrus bergylta (Ballan wrasse) in Ría de Vigo, Galicia (NW Spain). Our objective is to understand the behaviour of this coastal fish and how it may impact its vulnerability to fishing.

Habitat Areas for White Sharks

Species: White shark

Map View

Led by Rachel Robbins, the overall aim of the project is to define other important habitat areas for white sharks and the pathways between them.

Residence, Movement and Activity of Diamondback Terrapins

Species: Diamondback terrapin (Malaclemys terrapin)

Map View

Beginning in 2013, a field study led by Mike Arendt and team was initiated to compare the residence and movement patterns between diamondback terrapins captured in river vs. creek habitats in order to determine what, if any, correction factors were needed for interpreting CPUE trends in a river-edge based trammel net data set.

Riverine Movements of Shortnose and Atlantic Sturgeon

Species: Shortnose Sturgeon, Atlantic Sturgeon

Map View

Bill Post and his team at SCDNR, in cooperation with agencies/universities in NC and GA, has an array of ~600 receivers in many of the major river systems in the southeast. The goal is to gain a better understanding of riverine and near coastal movements of shortnose and Atlantic sturgeon on a coast-wide “big picture” basis and to possibly identify any life history gaps.

Striped Bass Movement

Species: Striped Bass

Map View

The objective of this study, conducted by Bill Hoffman and team, was to describe the extent to which striped bass move between federal and state waters, and assess the relative conservation benefit provided by the EEZ fishery closure.

Wave Glider Tracks Sharks

Species: White Sharks

Map View

Dr. Barbara Block of Stanford University Marine Sciences and her team have deployed a self-propelled, solar-powered wave glider equipped with a VEMCO acoustic receiver.

Northern Cod Migration

Species: Atlantic Cod

Map View

John Brattey and team have Vemco receiver networks deployed off the northeast coast of Newfoundland to monitor adult Atlantic cod movement patterns and investigate stock structure. Farmed cod have also been released along with local wild cod to compare dispersal and movements. Studies are ongoing.

The Sharks Project in Brazil - PROTUBA

Species: Nurse Sharks, Tiger Sharks, Stingrays

Map View

Andre Afonso and team aim to assess coastal habitat use in elasmobranchs off Recife.

Ecology of Giant Amazon River Turtles

Species: Giant South American Turtles

Map View

Richard Vogt leads research in documenting hatchling migration with adult females from nesting beaches. This is the first documentation of postnatal parental care in turtles.

Tracking American Eel

Species: American Eel

Map View

Julian Dodson and Melanie Beguer-Pon, in association with OTN, track migration routes to spawning areas of American eel in the St. Lawrence River.

Sea Trout Environment Interaction

Species: Sea Trout

Map View

Jan Davidsen studies the interaction between brown sea trout and the coastal marine environment using OTN receiver deployments.

Rivers in Real-time Migration

Species: Atlantic Sturgeon

Map View

Anne Wright conducts real-time migration studies of Atlantic Sturgeon which also serves as a collaborative outreach education program for students.
