As I’ve been reading industry news over the past several months I’m becoming increasingly convinced of the need for all of us to put more focus on “what works.” For more than a century in the U.S. and many other countries, agricultural demonstrati...
This study provides an important assessment of unionized ammonia (NH3-N) and total ammonia nitrogen (TAN) toxicity for juvenile longfin yellowtail, Seriola rivoliana. The authors assessed the median lethal concentration (LC50) after a 96 h exposure o...

We have seen a significant growth of the shrimp industry over the last decade. Total imports in 2022 were 3,248,338 ton (Van der Pijl, 2023), with additional production in China estimated at 1,487,501 ton (Fu-Chi, 2023). China and Vietnam in Asia (94...
Located in the central part of Southern Africa, Zambia is landlocked and surrounded by eight countries: Angola, Botswana, Democratic Republic of Congo (DRC), Malawi, Mozambique, Namibia, Tanzania and Zimbabwe. Zambia will be hosting the second Aquacu...
This study assessed the suitability of partial or full (100%) replacement of fish oil (FO) with microalgal oil (AO) in Atlantic salmon diets. This represents a novel approach as it is one of the first studies to follow fish through the entire product...
Recirculating Aquaculture Systems (RAS) have become part of the global aquaculture landscape. Announcements of new, planned investments in large-scale RAS in countries around the world appear frequently in the aquaculture news media. Yet RAS, as a vi...
Land-based aquaculture has lengthy lists of both pros and cons. Farming seafood on land can greatly reduce potential harm caused to fragile ocean and freshwater ecosystems; it can also be costly to build and power a facility. It offers next-level con...
