IOF SEMINAR – September 15, 2023<\/strong>
\nWelcome to our first FISH 500 Seminar of this academic year!<\/p>\n

The Gill-Oxygen Limitation Theory (GOLT): current trends and challenges<\/strong><\/p>\n

Join us as\u00a0world-renowned fisheries scientist, Dr Daniel Pauly discusses\u00a0Gill-Oxygen Limitation Theory (GOLT).<\/strong><\/p>\n

GOLT provides mechanisms for key aspects of the biology (food conversion efficiency, growth and its response to temperature, the timing of maturation, and others) of water-breathing ectotherms (WBEs). The GOLT\u2019s basic tenet is that the surface area of the gills or other respiratory surfaces of WBE cannot, as two-dimensional structures, supply them with sufficient oxygen to keep up with the growth of their three-dimensional bodies. Thus, a lower relative oxygen supply induces sexual maturation, and later a slowing and cessation of growth, along with an increase of physiological processes relying on glycolytic enzymes and a declining role of oxidative enzymes. Because the \u201cdimensional tension\u201d underlying this argument is widely misunderstood, emphasis is given to a detailed refutation of objections to the GOLT. This theory still needs to be put on a solid quantitative basis, which will occur after the misconceptions surrounding it are put to rest.<\/p>\n

Dr. Daniel Pauly is currently the Principal Investigator of the Sea Around Us initiative, a large research project devoted to identifying and quantifying global fisheries trends. He is also a Killam professor at the University of British Columbia\u2019s Institute for the Oceans and Fisheries.<\/p>\n

The concepts, methods and software which Daniel Pauly led and co-developed are documented in over 1000 scientific and general-interest publications, and are used throughout the world. This applies to the Ecopath modelling approach and software and FishBase, the online encyclopedia of more than 30,000 fish species, which was recently complemented by SeaLifeBase. He is a recipient of numerous awards, including the Tyler Prize for Environmental Achievement, the International Cosmos Prize, the Volvo Environment Prize, the Nierenberg Prize and the Frontiers of Knowledge Award in Ecology and Conservation Biology. He was named France\u2019s Chevalier de la Legion D\u2019Honneur in 2017.<\/p>\n
