Rashid Sumaila, Director of the Fisheries Economics Research Unit at the University of British Columbia and Associated Faculty at the Sea Around Us, will be visiting Perth and offering a lecture on February 19, 2019.
The Sea Around Us’ Deng Palomares and Daniel Pauly have just added a new item to their long list of publications: a chapter in Elsevier’s book Coast and Estuaries: The Future.
In their contribution, titled “Coastal fisheries: the past, present and possible futures,” Palomares and Pauly highlight the importance of coastal fisheries by pointing out that they made up 55 per cent of global marine fisheries catch from 2010 to 2014.
Carbon dioxide emissions from the fuel burnt by fishing boats are 30 per cent higher than previously reported, researchers with the Sea Around Us initiative at the University of British Columbia and the Sea Around Us – Indian Ocean at the University of Western Australia have found.
In a study published in Marine Policy, the scientists show that 207 million tonnes of CO2 were released into the atmosphere by marine fishing vessels only in 2016. This is almost the same amount of CO2 emitted by 51 coal-fired power plants in the same timeframe.
In over 80 per cent of fish species, the females, including those known as ‘big old fecund females,’ or BOFFS, grow bigger than the males. This long-established fact is difficult to explain with the conventional view of fish spawning being a drain on the ‘energy’ available for growth. If this view were correct, females, which are defined by their larger reproductive effort, would always remain smaller than males.
