Featured Scientist: Jose Quintanilla

Our annual surveys would not be possible without our wonderful collaborators from around the world. We'll dedicate several future blog posts to highlight these individuals, so that you can learn more about them, their research, and the valuable contributions they make to the survey. You can find previous posts here. Today we feature Jose Quintanilla from IEO!

My name is Jose Mª Quintanilla Hervás. I am one of the scientists in the Larval Ecology Group belonging to the Spanish Institute of Oceanography (IEO), which is the public organization that carries out research in the oceans of Spain. For the last decade, my research has been focused on larval growth of different species in the Mediterranean sea (such as sardines, anchovy, bluefin tuna) and how it is influenced by environmental and trophic variables.

This is my first time in this survey in the GOM. I'm very pleased to take part in it and to have the opportunity to continue the collaboration with our colleges from NOAA in order to improve our knowledge of bluefin tuna larval ecology from a multidisciplinary point of view in the framework of ECOLATUN project. One of my main interests is to establish a robust criteria for age reading of bluefin tuna larvae in order to be able to compare growth patterns of populations from Mediterranean and GOM and try to the determine the most important factors related with different growth rates in both areas taking into account that growth is one of the most important factors in larval survival and, therefore, in the recruitment and viability of the species.

Nowadays, our group is interested in the study of the potential effect of larvae feeding behaviour on their growth based on Stable Isotope Analysis (SIA) and Compound Specific Isotope Analysis (CSIA)
