The red emperor snapper, known as “pouatte” in New Caledonia, is valuable throughout its broad geographic range and a highly valued food fish locally. Declining wild catches and market demand have provided the incentive to carry out technical feasibility studies to determine its commercial aquaculture potential. 

The stable isotopes technique with δ13C and δ15N can be used to determine the relevance of different food sources to shrimp feeding during the pre-nursery phase of Litopenaeus vannamei culture. During this trial, different types of commercial feed, microalgae, Artemia sp. nauplii and bioflocs were used as food sources. 

The authors conducted studies to test the performance of young shrimp postlarvae in systems with different approaches to aeration and water handling. Proactive management through proper feed applications and water quality control were critical elements. 

Easily digested, live artemia offer important animal health benefits and improved performance when included in feeding regimes for larval shrimp. Pilot and commercial-scale trials have confirmed that artemia can be partially replaced in shrimp feeding. 

Research at the Oceanic Institute has been successful in overcoming bottlenecks associated with rearing small-mouthed fish larvae by finding a suitable first feed. Early work on the calanoid copepod Parvocalanus crassirostris focused on parameters necessary for successful maintenance of stock cultures. 

After experiencing disappointing survival rates following traditional artemia-based rearing protocols, the French hatchery Aquastream turned to a micropellet alternative to artemia. 

To meet demand and maintain the sustainability of the shrimp aquaculture industry, commercial synthetic artemia has been developed for use as a bio-secure replacement for live artemia in larviculture. 

Zebrafish offer a living model system for research in a wide variety of scientific disciplines. The Aquatic Resources Program at Children’s Hospital Boston recently identified an alternative feeding method that requires less labor. 

Research with sturgeon and carp species indicated that encapsulated artemia has high potential to carry probiotics or other beneficial microorganisms. 

The use of phages is an alternative to antibiotics in the control of pathogenic bacteria. Phage therapy offers low-cost, low-toxicity treatment and quick bactericidal effects. 

Hatcheries produce Korean rockfish seedlings in indoor tanks for sorting and grading. The fish grow well at relatively low water temperatures in net cages. 

Artificial diets are used to replace live artemia at commercial shrimp hatcheries, but complete replacement remains a challenge for strong grow-out results. 

At shrimp hatcheries, artemia replacement diets are used to replace live artemia, but complete replacement in commercial conditions remains a challenge. 

Research with sockeye salmon fry in Washington state demonstrates that bioencapsulated artemia can deliver therapeutic erythromycin more efficiently than pelleted feeds. 

For years the salinity of the brine in Great Salt Lake has been in steady decline, affecting the ecology and its major inhabitant, the brine shrimp artemia.
