Three potential Critical Angel Shark Areas or CASAs have been identified in the Eastern Mediterranean, specifically in Türkiye’s Fethiye Bay and Antalya Bay, which are part of the Turkish Riviera, and the Çanakkale or Dardanelles Strait, in the northwestern part of the country.

Paper on gigantism makes cover of Journal of Fish Biology
A recent paper authored by the Sea Around Us’ PI, Dr. Daniel Pauly, research assistant, Elaine Chu, and Dr. Johannes Müller from Leiden University, has made the cover of the June print issue of the Journal of Fish Biology, where it was introduced by a brief essay in the ‘Between the Covers’ section. The image that illustrates it is that of a large mythical sea creature known as an Aspidochelone, which appeared in a French bestiary around 1270 A.D.
Industrial fleets operating in the Indian Ocean turn off monitoring systems, fail reporting obligations
Industrial fleets from top fishing countries operating in the Indian Ocean and targeting export-market species such as tuna and squid are likely to disable monitoring systems to fish more than allowed and evade authorities, new research has found.
Forty-year-old concepts around fish respiration regain prominence in light of climate change
Before Dr. Daniel Pauly, now the principal investigator of the Sea Around Us initiative at the University of British Columbia, became a doctoral student, he spent two years doing fisheries work in Indonesia.
Having done his academic studies in Germany, he was surprised to discover a near absence of information on the growth of tropical fish. Thus, upon his return to Kiel University’s Institute of Marine Sciences, he decided to find out how fish grew; the idea was that if general patterns emerged, they could be applied to the many species in Indonesia and elsewhere in the tropics.
His doctoral dissertation was, consequently, built around identifying the factors that govern fish growth.
Marine sharks and rays ‘use’ urea to delay reproduction
Urea – the main component of human urine – plays an important role in the timing of maturation of sharks, rays and other cartilaginous fish.
A new study by researchers with the Sea Around Us initiative at the University of British Columbia’s Institute for the Oceans and Fisheries found that high urea concentrations common in cartilaginous fish, particularly oviparous marine species, allow them to mature and begin to reproduce at a larger fraction of their maximal size.
