A system and method for shrimp aquaculture is disclosed. All growth phases and essential operations are modularized and integrated in a system controlled by a cyber-physical platform. The system comprises one or more post-larvae nursery module(s), grow-out production module(s), recirculating aquaculture system (RAS) module(s), feed distribution module(s), and regulatory elements comprised of Program Logic Controllers (PLCs) integrated with Human Interface Modules (HIMs).

A method for producing an L-amino acid such as L-lysine is provided. An L-amino acid is produced by culturing a bacterium having an L-amino acid-producing ability, which has been modified so that the activity of a carotenoid biosynthesis enzyme is increased, in a medium, and collecting the L-amino acid from the medium.

An ecological conservation system and method for an artificial coastal wetland are provided. The system can include a fish and shrimp ecological breeding area, an artemia breeding area and a bromine extraction and salt production area, where a water inlet channel is arranged on a side of the fish and shrimp ecological breeding area; a sedimentation and biological purification channel is arranged between the fish and shrimp ecological breeding area and the artemia breeding area; a drainage channel is arranged between the artemia breeding area and the bromine extraction and salt production area; and waterfowl habitat islands are built in the fish and shrimp ecological breeding area and the artemia breeding area.

Provided is an aquacultured crustacean having improved umami, uses thereof, and a method for producing the same. The crustacean does not burrow in sand, contain glycine and alanine, and has 2400 mg or more of free amino acids per 100 g of abdominal muscle. The content of glycine is 550 mg or more per 100 g of abdominal muscle, and the content of alanine is 140 mg or more per 100 g of abdominal muscle.

Embodiments of the present disclosure describe a raceway comprising a sloped base with an apex, a divider extending upward from the apex, two side walls, each opposing and parallel to the divider sufficient to form two elongated channels on the sloped base; and at least two tapered ends in fluid communication with the channels, each tapered end including an end wall, a pit, and a sloped floor extending from the sloped base to the end wall or pit.
