Alabama-based startup is developing a conveyor belt system to culture microalgae in less space than raceways and with a more efficient collection system.
Hatch Blue’s fourth cohort performed their pitches online for the first time, showcasing a spectrum of aquaculture product and service businesses.
Study shows that microalgae assists the stability of small-scale RAS, and that microalgae can be used to manipulate the bacterial community.
Microalgae – an important live feed in shrimp and fish hatcheries – can be produced in both open and closed systems, with the latter having some advantages.
Results of this study demonstrated that a commercial, granular, SCP-based algaecide corresponding to 2.5 mg/L H2O2 can be recommended as an eco-friendly strategy to effectively remove populations of the cyanobacterium Planktothrix sp. without compromising water quality or other plankton communities.
A greenhouse in Belgium believes its innovative shrimp feed product, made from freeze-dried microalgae, packs the necessary nutrients for the crustacean’s most vulnerable life stage: the first three days of its life.
Green water, which describes the typical water color in tropical aquaculture facilities, consists mainly of various phytoplankton species along with bacteria, protozoa and zooplankton. It is relatively easy to produce without any supplemented nutrients.
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.
