Satellite imagery was used to determine sea surface chlorophyll concentrations. Mangroves and seagrasses were largely absent, due to the high-energy conditions and unstable substrata. Coral development was also limited, principally because of cold upwelling sea temperatures. Macroalgal prevalence and abundance were greater on account of high nutrient levels. Nesting sites of three turtle species (Green, Hawksbill, and Loggerhead) were all impacted at low levels. Coastal construction was small-scale and located near larger towns (Al Mukalla, Foua and Shehir), while water- and land-based pollution and fishing were widespread but minimal. Fish abundance showed significant positive correlation with chlorophyll concentration. These and other associations...

It highlights the importance of the ‘human’ elements in project design, implementation, and evaluation. It argues that while external factors and technical issues may be strong determinants of success or failure, more important is the ‘human element’ in terms of the skills, needs, motivations and aspirations of project designers, implementers, evaluators, and beneficiaries.

The update included publicly available discard data in the last 20 years to establish a baseline of a time series of global marine fisheries discards. This is essential for monitoring the status and trends of discard management, which is the first step of the ecosystem approach to fisheries management cycle. In addition, the study developed a new fisheries data table incorporating landings data from the FAO Global Capture Production dataset (FishStat J) from 2010 to 2014, which allocated the landings to over 2 000 fisheries worldwide. The current study estimated that the annual discards from global marine capture fisheries between 2010 and 2014 was 9.1 million tonnes (95% CI: 6.7 – 16.1 million tonnes). About 46 percent (4.2 million tonnes) of total annual discards were from bottom trawls that included otter trawls, shrimp trawls,...
