B2E Technological Sonar Initiative #34
Back to the office, back to fresh innovations! AI now estimates fish weight in aquaculture, enhancing monitoring and management. Innovations in measuring macroalgae growth support carbon credit systems, while new algae-based ingredients improve food texture. In marine biotechnology, improved photobioreactors optimize algae cultivation, and genetically modified salmonids resist viral infections. Algal extracts are being used in medical treatments and sustainable fertilizers, pushing the boundaries of marine science even further. Explore these breakthroughs and ride the wave of discoveries!
AQUACULTURE
Automated system and method for estimating average fish weight in an aquaculture environment
The present disclosure relates to an automated method, computer program, and system for estimating the average fish weight in an aquaculture environment. An underwater camera in the aquaculture environment captures video frames from the environment. These frames are inputted into a machine-learning detection model trained to detect fish. The machine-learning vision detection model identifies a virtual box region around detected fish and outputs the size and location for the virtual box regions and pixel data related to the virtual box region and the frame. This size, location, and pixel data is processed and then inputted into an AI-based length estimation model, which computes a fish length for each virtual-box region inputted into the model. Using an analytical model, the system then calculates the average fish weight from the fish length.

Method and apparatus for measuring export of macroalgae or aquatic biomass and systems for confirming and monitoring carbon removal credits based on marine biomass
Disclosed are a system and method for growing and/or monitoring macroalgae and aquatic plants in a large body of water. The method includes placing a mass or collection of the seaweed/aquatic plants in the body of water at a location where the water is at least 300 meters deep and monitoring the depth of the seaweed/aquatic plants until the seaweed/aquatic plants sink below a sequestration threshold depth. The system includes a platform on or from which the seaweed or aquatic plants are grown, wireless detection equipment on the platform, and a wireless data signal transmitter on the platform, configured to transmit a wireless signal that indicates the depth of the sinking seaweed or aquatic plants.

Texturized-protein food ingredient
The present invention relates to a texturized protein food ingredient in which an algae-derived protein raw material is used, the food ingredient having exceptional color, aroma, and mouthfeel. This texturized-protein food ingredient is characterized by containing a texturized protein obtained by texturizing a raw material mixture including an algae-derived protein raw material and, a protein raw material that is different from and that has a protein content of 70 mass % or greater. Combining the algae-derived protein raw material and the protein raw material that is different from and that has a protein content of 70 mass % or greater, as protein raw materials, makes it possible to obtain a texturized protein having exceptional expansion properties.
