System and methods for monitoring the growth of an aquatic plant culture and detecting real-time characteristics associated with the aquatic plant culture aquatic plants. The systems and methods may include a control unit configured to perform an analysis of at least one image of an aquatic plant culture. The analysis may include processing at least one collected image to determine at least one physical characteristic or state of an aquatic plant culture. Systems and methods for distributing aquatic plant cultures are also provided. The distribution systems and methods may track and control the distribution of an aquatic plant culture based on information received from various sources. Systems and methods for growing and harvesting aquatic plants in a controlled and compact environment are also provided. The systems may include a bioreactor having a plurality of vertically stacked modules designed to contain the aquatic plants and a liquid growth medium.

Bioreactor systems for culturing mixotrophic microorganisms in open cultures on a large scale are disclosed herein. Embodiments of the system comprise organic carbon delivery systems and submersible thrusters suspended on adjustable support structures.

The present disclosure relates to an algal cultivation system comprising an algal pond. The algal pond comprises a growth chamber containing algal culture which is exposed to light to enable rapid growth of algae therein, and a regeneration chamber which is substantially devoid of light and configured to provide a residence time to algal culture for repair of damaged proteins of algal cells. The present disclosure also relates to a process for biomass production, comprising circulating algal culture using convection current or forced convection, between the growth chamber and the regeneration chamber. The system and process facilitate in increasing biomass and mitigating salinity and/or temperature variations in the algal culture (A).

The present disclosure relates, according to some embodiments, to apparatuses, methods, and systems for cultivating a microcrop involving a floating coupling device. More specifically, the present disclosure relates, in some embodiments to apparatuses and methods for cultivating Lemna for extracting proteins and/or carbohydrate rich products. In some embodiments, a bioreactor system for culturing a microcrop may comprise: a bioreactor container configured to contain the aquatic species in sufficient growth medium to permit normal growth of the microcrop, at least one coupling device comprising a star, and a propulsion mechanism configured to apply sufficient force to the at least one coupling device to cause motion thereof.

An open raceway algae cultivation system includes a channel configured to contain an algae cultivation fluid. The channel includes a contraction zone having a width and a depth and an expansion zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel and includes an entrance and an exit. A width of the contraction zone decreases leading into the entrance of the pump, and a depth of the contraction zone is greater than a depth of at least a portion of the channel located outside of the contraction zone. A bottom of the channel at a beginning of the contraction zone is lower than a bottom of the channel at an outlet of the expansion zone, and the contraction zone increases in depth along at least a portion of its length.
