Cayman Turtle Farm: Island Wildlife Encounter in West Bay, Grand Cayman, Cayman Islands is the first commercial sea turtle farm in the world to have achieved the 2nd generation of Green Sea turtles bred, laid, hatched and raised in captivity.  Visitors are welcomed to the site which has been developed into a mini theme park attraction featuring island wildlife in addition to turtles of all ages, for example indigenous and Caribbean birds in a free-flight aviary, a large salt-water crocodile, sharks and other marine predators, iguanas, and a nature trail full of various other flora and fauna.Cayman Turtle Farm also participates in leading research on the biology and care of sea turtles.  In 1984 Cayman Turtle Farm participated in an international project to help conserve Kemp's Ridley sea turtles, and the farm achieved the first successful captive breeding of the species for later release in that species' native territory to help boost the wild population.  CTF's stock of Green Sea turtles of a wide range of known ages from hatchlings to over 40 years old, and the CTF experts' experience in the husbandry of these exotic animals, have created unique opportunities for learning more about these magnificent creatures.  Some 100 scientific papers have been published or presented based on research in which Cayman Turtle Farm was involved.  The release of satellite-tagged 2nd-generation captive-bred turtles will help expand knowledge of the adaptation and behaviour of captive-bred turtles released into the wild.More information about Cayman Turtle Farm and its programmes is available at www.turtle.ky


Abstract:
Turtles in this group add to over 31,000 captive-bred Green Sea Turtles released from the Cayman Turtle Farm since 1968.  Tagging studies (living tags) have shown that females reared from eggs on the farm and released in the 1980s are now returning to beaches on the Cayman Islands to nest and complete their life cycles.

Central Great Barrier Reef shark nursery area survey (NERP TE 6.2, JCU), Australia (2011-2014)

Keywords: Occurrence
Temporal coverage: 2011/2014

This dataset contains the catch data from seasonal gillnet and longline surveys of shark nursery areas in the Central Section of the Great Barrier Reef Marine Park (2011-2014).
Sampling occurred seasonally in nine bays along ~ 400 km of the tropical north Queensland coastline: Rockingham, Halifax, Cleveland, Bowling Green, Upstart, Abbott, Edgecumbe, Woodwark/Double and Repulse Bays. Of these nine bays, five were sampled regularly, the others (in italics) were sampled only once as part of a broader survey. Sampling sites were dominated by silty substrates, and mudflat and/or mangrove-lined foreshores. Between October 2011 and November 2013 eight rounds of fisheries-independent surveys were undertaken to collect data on the shark community across the study region. Within each bay sampling occurred randomly within sixteen 0.9 km wide strips running perpendicular to the shore. Two groups of eight strips were placed within each bay to spread the sampling across different habitat types and management zones (i.e. gill-net fishing allowed and gill-net fishing prohibited) where possible. During each round, each bay was sampled over four days allowing for two days of sampling in each group of strips. The bays vary in size and so the relative proportion of area sampled varied between bays.

Abstract:
Delfini Metropolitani is a long term reserach project of Acquario di Genova to study the ecology of cetaceans and, in particular, of bottlenose dolphins (<i>Tursiops truncatus</i>). The study area is located along the Eastern Ligurian coast, between Genoa and La Spezia. The research platforms are two 5.10 m long inflatables. Research activity is conducted during the whole year, depending on weather conditions.

Purpose:
The project is mainly focused on the bottlenose dolphin with regards to habitat use, home range analysis, abundance estimates, and interactions with human activities (fishing, trawling, sea traffic). We use photo-ID techniques for abundance estimates, home range analysis and social structure analysis. We use ArcGIS 9.3 as a software tool for spatial analysis.

OTN Bras d'Or Lakes Array, OTN Bras d'Or Lakes Array - Tag Release Metadata

Keywords: Observation, Occurrence, Samplingevent, EARTH SCIENCE &gt; BIOLOGICAL CLASSIFICATION &gt; ANIMALS/VERTEBRATES &gt; FISH, ACOUSTIC TAGS
Temporal coverage: 2012/2014

This is the OBIS extraction of the OTN Bras d'Or Lakes Array project, consisting only of the release tagging metadata. i.e. the locations  and dates of tagged animal release. If readers are  interested in the full source  dataset they should refer to the OTN web site  (members.oceantrack.org). Abstract: The Bras d'Or Lakes Array will use OTN theory and technology to determine the ecological connections between Canada's inland sea (the Bras d'Or estuary of Cape Breton), its watershed, the Scotian Shelf, the Gulf of Saint Lawrence and the NW Atlantic Ocean. The intent is to fully instrument the sites of exchange between the major river catchements of the watershed and the estuary, the channels linking the major basins of the estuary, and all channels of exchange between the estuary and the surrounding ocean. Motile anadromous, catadromous, and marine species of significance (e.g., Atlantic salmon, American eel, Atlantic cod) will be acoustic tagged in rivers, bays, banks, and basins of the Bras d'Or to track their movements within the estuary and its watershed, and between the estuary and the surrounding OTN arenas of the NW Atlantic Ocean.  The Bras d'Or Lakes Array will be located throughout the Bras d'Or estuary, including all channels connecting the estuarine waters to those of the surrounding ocean, the channels connecting the major basins of the estuary, and the mouths of the main rivers flowing into the estuary. The initial array is composed of 15 stations. An additional 11 sites are proposed for subsequent years, depending on the results obtained during the first tagging experiments.
