XperCount, aka the “magic bucket,” uses optics and photonics to deliver 95 percent accurate count of microorganisms, such as fish or shrimp larvae, in just seconds. 

Bill Mook’s oyster farm is adapting to more frequent and intense rains, more acidic and warming seawater and other challenges that climate change brings. 

The use of biofloc technology (BFT) is increasing in the commercial production of several important aquatic species, as it can increase production and efficiency and minimize the potential impacts of effluents. This study showed that BFT systems without water exchange and supplemented with molasses or dextrose as a carbon source yield adequate production and water quality during the hatchery phase of L. vannamei. 

Variability in the quantity and quality of larval yields limit aquaculture growth. New biotechnological advances promise to revolutionize the way we assess and solve bottlenecks. A study demonstrated the use of metabolomics to assess and classify mollusk larvae quality and identify biochemical pathways that may reveal further important insights. 

Aquatic plants and animals get the essential nutrients calcium and magnesium from water and food. Calcium concentrations impact the hydration and development of eggs in a hatchery, where calcium carbonate precipitation can be troublesome. 

While sea cucumbers are one of the most prized seafoods in China and Asia, their production suffers from suboptimal juvenile production. The use of proper feeds and overall management in the nursery can improve yield and survival. 

Investing in the quality of shrimp postlarvae by applying state-of-the-art hatchery management results in a significant return on investment. Nutrition and health protocols have large impacts on postlarvae quality that last beyond the early life stages. 

A partnership among the private, academic and government sectors is advancing the development of mariculture in Rio de Janeiro, Brazil. Ongoing projects include a marine fish hatchery, demonstration unit and experimental integrated multi-trophic aquaculture system. 

Mahimahi is a fast-growing, high-value fish species with excellent potential for aquaculture. The technology for maturation, spawning, larval rearing, fingerling production has been mastered, yet progress toward commercial development has been slow. 

Proper management of broodstock nutrition encompasses providing the right amounts of the proper specialized nutrients during the right developmental stages. 

The REPROSEED project is taking a focused, cooperative approach to better understanding of optimized mollusc hatchery/nursery-rearing techniques. 

The quality of postlarvae supplied by a shrimp hatchery can vary considerably. Common myths, such as acceptance of low survival and insufficient concern for water quality, can contribute to lower animal quality. 

To evaluate the value of incorporating tail weight and yield in shrimp-breeding programs, the authors carried out a study to estimate heritabilities and genetic correlations for the traits. 

Spiny lobsters are a premium seafood whose culture has depended on wild-caught seedstock. An Australian company is helping shift the farming paradigm to more sustainable hatchery production. 

Cobia is a top emerging candidate for tropical and subtropical marine fish aquaculture. The University of Miami Experimental Hatchery has led ongoing research to advance the viability of raising hatchery-reared cobia.
