Join us on 2 September at 12 noon GMT for a free webinar on the Status of the use of Artemia cysts in fish and crustacean hatcheries around the world. The webinar is facilitated by the International Artemia Aquaculture Consortium (under formation). The webinar will document differences in practices used by fish and crustacean hatcheries in the use of Artemia cysts for the preparation of live feeds. Speakers include technical experts using Artemia in the production of shrimp, freshwater prawn, mud and mitten crabs, seabass, sabream and other marine fish from Bangladesh, Brazil, China, Ecuador, Greece, India, Spain, and Thailand. Participation is free but registration is required.

The Fish Health Section of the Asian Fisheries Society will convene a webinar via Zoom on 21 April, from 12:00 to 15:00 Bangkok time (GMT +7). Topics include: Stress-related non-infectious disorders in fish (Prof. George Iwama, Quest University, Canada); Nutritional diseases of aquatic animals (Prof. Orapint Jintasataporn, Kasetsart University, Thailand); Harmful algal blooms and fish kills (Prof. Lim Po Teen, University of Malaya); and Aquaculture ecotoxicology (Dr Roger Chong, CSIRO Australia). Participation is free, but registration is required.

Coral trout Plectropomus leopardus is an emerging exported grouper commodity in Indonesia. The demand for coral trout fingerlings has been increasing and the value of this species is the highest among groupers. However, the rearing of coral trout larvae is notoriously more ‘difficult’ than other groupers. This article describes research on coral trout larval rearing protocols conducted by the Institute for Mariculture Research and Fisheries Extension, which has achieved a survival rate of 12%.
