Introduction to the workshop

A virtual workshop is planned for February 22-23 2022 (12:00-15:00 UK time) to explore existing knowledge and data on Harmful Algal Blooms (HAB) and impacts on fisheries and finfish aquaculture in the Arabian Gulf. The workshop is being sponsored by the UK and Kuwait Governments and is endorsed by GlobalHAB. The theme of first day is understanding the susceptibility of the Arabian Gulf and adjoining sea areas to harmful algal blooms (HABs) and impacts on fish health and food safety, and the second day would focus on developing early warning systems (EWS) for HABs for mitigating impacts on fisheries and aquaculture.

 Background Information 

Global aquaculture production from finfish, shellfish and seaweed is projected to grow by 32% from 2018-2030, helping to ensure food security and alleviate pressures on wild stocks from overharvesting and climate change. In the Arabian Gulf finfish aquaculture alone is projected to grow by over 7% between 2018 and 20241. However, the growth of the aquaculture industry is threatened by HABs, which are being observed increasingly at aquaculture sites around the globe, with some HAB species causing mass fish mortalities. Numerous mass fish kills have been recorded in the Arabian Gulf and Sea of Oman and many of these coincide with blooms of ichthyotoxic HAB species and/or high biomass blooms that subsequently decay and cause oxygen depletion in the water column2-4. As an example, in the figure above, chlorophyll concentrations captured by the MODIS Aqua sensor (NASA) represent a bloom of the harmful alga Margalefidinium (Cochlodinium) spp. (in Anderson et al., 2017; Courtesy of R. Kudela and NASA).
