Like so many innovative solutions achieved in digital technology, a potential fix to aquaculture’s existential issue – the sustainability of feeds – was born in Silicon Valley. In a garage, no less.

The diatom Thalassiosira weissflogii is important in the aquaculture industry to feed shrimp and shellfish larval stages in hatcheries. This study examined culture conditions for this diatom and determined that it can be successfully cultured semi-continuously and without population crashes.
Responsibility
Global, sustainable mariculture production, developed on a massive, sustainable scale and using just a small fraction of the world’s oceanic areas, could eventually match the output of land-based agriculture production. Scale and international law considerations require the involvement of many stakeholders, including national governments and international organizations.

Innovation is leading to new ingredient options for renewable sources of omega-3 fatty acids. But Replicating long chain fatty acids is a tall order, Advocate contributor Lisa Duchene discovered.

Muchos estanques acuícolas requieren aireación mecánica tanto para aumentar los niveles de oxígeno disuelto como para favorecer la mezcla de las aguas ricas y pobres en oxígeno, que también ayuda a prevenir el volteo.

The control of temperature and light intensity in microalgae culture in outdoor tanks is difficult. Progress in algal biotechnology and the use of photo-bioreactors, metabolic engineering and other advances supported development of a novel underwater light bank reactor that allows for more effective light utilization by cultured microalgae.

Promoting water circulation during the day time is an effective strategy to enrich pond water with oxygen produced by photosynthesis, and can significantly reduce the costs of night time supplemental aeration.

A growth trial in Canada evaluated the use of algae biomass to increase the concentration of long-chain polyunsaturated fatty acids in the tissues of rainbow trout.

About 30 percent of global microalgae production goes to animal feeds, with large applications in aquaculture, particularly for larval stages.

As part of the development of rearing procedures at the first commercial marine fish hatchery in Venezuela, a study induced spawning of lane snappers and evaluated the survival of larvae fed rotifers, two microalgae species and enriched artemia.

The entrapment, storage and processing of microalgae into alginate beads is a useful technology for stock culture management.
