Smart FAD Business Card Tags Scaling-up OTN SWIOFP

Linked projects

The use of instrumented buoys as underwater life observatories, benefiting from the capacity of FADs to attract many tropical pelagic species, yet relates to several international projects.

The Smart FAD project

Presentation

The Smart FAD project is funded by the Pelagic Fisheries Research Program, PFRP, Hawaii (manager: Dr J. Sibert, www.soest.hawaii.edu/PFRP). PIs: Kim Holland (University of Hawaii) and Laurent Dagorn (IRD). The objective is to develop an instrumented FAD with a sonar for observing fish aggregations around anchored FADs. The system is developed by Dr Jules Jaffe from the Scripps Institution of Oceanography (San Diego, U.S.A.).

The technical approach (design of the sonar) is slightly different from the one adopted by the FADIO I project, but the objective is to obtain several technical solutions to instrument FADs.

 

Development of 'Business Card' Tags: Inter-individual Data Transfer

Presentation

The 'business card tag' project is funded by the PFRP (Hawaii). PIs: Laurent Dagorn (IRD) and Kim Holland (University of Hawaii). The objective is to develop a two-way 'receiver tag' prototype (Vemco, www.vemco.com). The receiver tag prototype should be able to identify and store acoustic signals sent by other acoustic tags. The receiver tag should be small enough to be mounted on/in tunas or similar sized animals.

These new tags will allow study the ecological relationships between species, as well as measure time residency of fish at FADs without the need to instrument all FADs with listening stations (FADs can be equipped with a business card, to replace a listening station).

 

Scaling Up: Linking FAD-associated Local Behavior of Tuna to Regional Scale Movements and Distribution

Presentation

The 'Scaling-up' project is funded by the PFRP (Hawaii). PIs: Kim Holland (Hawaii) and Laurent Dagorn (IRD). The experiment will use three types of tags (coded acoustic, internal and external archival) to give short, medium and long-term movement and behavioral data for fish originally caught in association with Hawaiian coastal FADs.

This project will help study the impacts of anchored FADs on tuna behaviour at short, medium and long term.

 

Ocean Tracking Network (OTN)

Presentation

The Ocean Tracking Network (OTN) is a 168 million US$ conservation project. It is a large scale global initiative which aims to supervise oceanic parameters and marine life response to them.

The OTN network

The OTN foresee to develop itself in the 5 oceans (Atlantic, Pacific, Indian, Arctic and Antarctic). The network will consist of an acoustic receivers serie set at one kilometre interval on the oceanic floor. It will allow following the movements of marine animals equipped with acoustic tags.

These receivers will also be equipped with sensors allowing real time measurements of certain oceanic parameters. Physical information (oceanic parameters) and biological one (acoustic data) will be transferred to a central database, giving thus reliable and brought up to date international recordings which can be analysed by the scientists and use for various environmental actions.

The interest of this method lies in its reliability and its profitability for the collection of information compared to the traditional campaigns at sea.

Link with FADIO

The OTN project is built on international partnership basis, essential to obtain reliable and complete data. OTN planned to set up especially on continental shelves. Within the framework of this project, FADIO would deal with the pelagic field (in the Indian Ocean) by equipping FADs with acoustic receivers. That corresponds to the same technologies and protocols used during FADIO I.

 

SWIOFP

Presentation

SWIOFP (South West Indian Ocean Fisheries Project) is a multilateral research project which global goal is to lead to an ecological management of marine resources for their sustainable and profitable exploitation by the coastal countries of this area.

The SWIOFP area

The total budget of this project is 22.64 millions US$, including 12 millions US$ from the GEF, 800 000€ from France, 2 millions US$ from Norway in the form of time boat, and approximately 7.64 millions US$ of the participating countries.

SWIOFP is supported by the GEF as a recipient of the Large Marine Ecosystem program (LME).
Indeed, the South-West Indian Ocean area is the site of one of the most important and dynamic LME in the world, which still reveal a significant evolution in its unloaded capture, contrary to the majority of the other main fishing areas defined by the FAO.

Moreover, the Indian Ocean is the only one to be surrounded by developing countries, of which almost half of the population relies on marine resources. Thus, Seychelles, Comoros, Madagascar, Mozambique, South Africa, France (La Réunion island) and Mauritius decided to conceive a collaborative project which embrace the whole of their needs and attempts relative to fishing in a regional context.

These 9 member countries are framed by countries or commissions working as project observers.

Link with FADIO

The SFA (Seychelles Fishing Authority) is the institution representing Seychelles within SWIOFP. Seychelles are responsible for the “assessment and sustainable use of pelagic fish” component. Within this component, actions on anchored FADs for countries partners of SWIOFP are planned, in order to constitute a first instrumented anchored FADs regional network in the Indian Ocean. The objective is to use these local networks for better knowing the resource behaviour.
