GERUNDIO

Objective

The main objective of this project is to produce updated estimates of age, growth and reproduction parameters for the stock assessments of Indian Ocean tropical tunas (bigeye, skipjack and yellowfin), swordfish and blue shark.

For this, we will develop a sampling scheme to collect samples of otoliths, gonads and other body parts, and analyse them in combination with samples collected in previous research initiatives.

Strategy

Our strategy consists on identifying key research analysis (e.g. bomb radio-carbon dating of otoliths for age validation) for new samples, developing and applying consistent methodologies for preparing and analysing samples, and maximizing the research opportunities from previous and current international collaborations and building research capacity in the Indian Ocean.

The data collected will allow to know the productivity levels of these species, a key parameter for the development of sustainable fisheries management plans.

International Consortium

To achieve this, we have built an international consortium of research institutions with considerable experience in sampling in the Indian Ocean and internationally recognised experts in the fields of estimating growth and reproductive parameters. This consortium has links with other research projects, which ensures access to a stock of previously collected samples to help meet the objectives of this project within the agreed timeline.
