AQUACULTURE

1. Animal feed based on microorganisms to modulate the level of undesirable flavors in aquaculture

Methods and compositions are provided to reduce undesirable flavors in aquatic species or in aqueous systems. Microbial biomass or its derivatives are provided in the form of a feed composition or in the water in an aquaculture production system or other aqueous system, thus modulating the level of one or more compounds that produce undesirable flavors.

2. New Value from Food and Industrial Waste – Bioaccumulation of Omega-3 Fatty Acids from an Oilseed Microbial Biomass Combined with a Brewing Industry Byproduct Using Black Soldier Fly (Hermetia illucens) Larvae

Research on insect-based bioconversion is intensifying as it addresses the problem of reducing and reusing food and industrial waste. To achieve this goal, we need to find more ways to combine waste with insects. With this objective, spent grains from breweries (SGB) – a food waste product from the brewing industry – combined with the oilseed biomass of the thraustochytrid *Schizochytrium limacinum* grown in crude glycerol – a major waste product from biodiesel production – were successfully used to cultivate *Hermetia illucens* larvae.

3. Wireless Sensor Network-Based Retention Tank Monitoring System and Monitoring Method
In aquatic product production, tracking changes in water quality is an urgent aquaculture problem that needs to be solved. Currently, single sensors are often used for data detection, and there is no coordination between sensors or between sensors and actuators, resulting in a lack of a unified monitoring and control mechanism. The present invention discloses a retention tank monitoring system based on a wireless sensor network and a monitoring method provided therein, characterized by unsupervised operation and automated execution, obtaining environmental data from a retention tank in real time and analyzing the data using a suitably trained machine learning algorithm and triggering a control action on the actuator to perform a corrective action on the retention tank for optimal system operation.

5. Method and Device for Increasing the Proportion of Meat Used in Fish, Poultry or Other Meat Products

The invention relates to a method used in the production of main products transported in plurality along a processing line and consisting of fish, poultry or other meats that contain, in addition to the main products to be extracted, non-edible components to be removed (components for removal) and also contain edible residual products that remain in said components for removal, wherein, when the components for removal are removed from the main products, the edible residual products remain in the products for removal.

6. Dried food and method for producing dried food

Provided are: a dried food that is less susceptible to flavor deterioration due to shellfish oxidation and has high resilience in boiling water; and a method for producing it. An aqueous solution containing 0.1-10% by weight of cyclic oligosaccharide is made to permeate the shellfish, and the shellfish permeated with the cyclic oligosaccharide are dried until the water content becomes a maximum of 6.0% by weight. The dried food has a maximum of 6.0% by weight of water content and contains 0.1-10% by weight of cyclic oligosaccharide.

9. Seafood waste reprocessing: the challenge of developing clean aquatic meat from fish cells

This study focused on cells obtained from fish fins, which were often discarded as food waste and had the potential to alter their morphology with simple treatments, creating the possibility of processing fish fin cells into clean meat (i.e., meat produced in vitro; artificial meat grown in the laboratory using tissue engineering techniques).
