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) as a follow up to the recommendations of the recent article Past, present and future scenarios for SDG-aligned brine shrimp Artemia aquaculture in FAO Aquaculture News.

The goal of the webinar is to document differences in practices used by fish and crustacean hatcheries in the use of Artemia cysts for the preparation of live feeds. Over time, the practices used by hatcheries in Asia, Europe and Latin America have diverged from the good aquaculture practices for Artemia production recommended by FAO in the 1991 Live Food Manual.

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.

The programme (see below) will include:

• An introduction to the Artemia cyst hatching process and the crucial parameters to ensure optimal hatching and preparation of Artemia for use in the hatchery feeding of fish and crustaceans.
• Presentations on techniques for Artemia cyst decapsulation, hatching, umbrella/nauplii separation, cold storage, heat killing, freezing and enrichment used by small- and large-scale hatcheries from around the world.
• A Q&A session with the speakers.

The webinar will produce a report with specific recommendations for the FAO Artemia workshop to be held at the Global Conference on Aquaculture, Shanghai, September 22, 2021. The workshop will contribute to preparation of updated recommendations on how to better use Artemia in hatcheries as an important input for a new FAO Artemia manual and future training programmes for local hatcheries.

Registration

Participation is free, but please register in advance for this webinar. After registering, you will receive a confirmation email containing information about how to join the webinar, which will be held via Zoom.
