At the forefront of innovation in aquaculture and the food industry, revolutionary methods are emerging for cephalopod farming, optimizing diets for juvenile salmon, and even increasing the vitamin D content in common food products. Furthermore, biomass and food processing technologies are revealing secrets to maximizing energy efficiency. Innovations in the extraction of bioproducts from cyanobacteria or snow crabs offer potential for both the production of high-value nutrients and bioactive compounds for the health sector, contributing to the reduction of environmental impacts and paving the way for a more sustainable future in health and food.

AQUACULTURE

Cephalopod farming method, cephalopod farming equipment, protozoan prevention method, and protozoan extermination method

Conventional cephalopod aquaculture techniques often exhibit a high larval mortality rate; therefore, new techniques are needed to overcome this problem. This invention describes a method for rearing cephalopods, including cephalopod rearing equipment, a method for preventing protozoa, and a method for exterminating protozoa, which involves periods of high water exchange, as well as control of protozoa density, resulting in a reduction in the mortality rate during cephalopod larval growth.

Optimization of micromineral supplementation in diets for juvenile Atlantic salmon, with reference to the holistic performance of the fish in terms of growth, health, well-being and potential environmental impacts

The inventory of ingredients in aquatic animal feed is constantly changing, from marine to plant-based, and is currently evolving towards the incorporation of increasing amounts of low trophic level raw materials or those originating from sidestream or circular economy sources. However, it is essential to meet the micronutrient needs of farmed fish to ensure healthy and efficient growth under normal and challenging conditions. In this study, a trial based on a 2 × 4 factorial design with three replicates for each feed treatment was conducted, in which juvenile Atlantic salmon were fed one of eight experimental diets supplemented with organic or inorganic mineral premixes (copper, iron, manganese, selenium, and zinc) at four levels of feed inclusion. The results of this study provide valuable information for the development of sustainable aquaculture practices and feed formulation.

Enzymatic Preservation of Animal Feed

The present invention relates to a method for preserving animal feed or feed additives using an enzymatic antioxidant that prevents the degradation of proteins, vitamins, fats, and lipids contained in the ingredients of animal feed. Polypeptides with catalase activity and/or superoxide dismutase activity [PG1][TA2] or a combination of polypeptides with both activities are used as preservatives.

LIVING MARINE RESOURCES – NEW USES AND ADDED VALUE

System for processing biomass or food product or fish for processing, achieving an optimization of thermal potential energy in relation to the volume of a refrigerant fluid [TA3]

The present technology is related to the aquaculture industry and food production in general. In particular, the present technology relates to a system for processing food portions, which achieves optimization of thermal potential energy, even under discontinuities in the process of loading food portions into a cooling tank, due to heat exchange between the input object and the medium, with a smaller cooling volume, ensuring a more efficient average process productivity.

Vitamin D Production Device

In the vitamin D production method of the present invention, a food product is irradiated with light in the wavelength range of 280-315nm inclusive, with a cumulative amount of light of 45 mJ/cm2 or higher. The food product is selected from dairy products, eggs, shellfish, crustaceans, and cephalopods. According to this vitamin D production method, it is possible to increase the vitamin D content of a variety of food products.

MARINE BIOTECHNOLOGY

ORGANIC TISSUE DEMINERALIZATION

The present invention relates to a method for processing an organic raw material containing mineralized tissues (e.g., fish scales) by enzymatic hydrolysis to produce hydrolysates and mineralized tissue remnants that include a protein fraction. The invention further comprises a processing plant for the organic raw material containing mineralized tissue and a method for demineralizing mineralized tissues to obtain solubilized minerals and demineralized tissues.

Sequential Extraction of High-Value Byproducts from Snow Crab (Chionoecetes opilio). Processing of By-products Using Environmentally Friendly Methods

In Atlantic Canada, the snow crab (Chionoecetes opilio) is the most important commercial species for the fishery and the rural economy. Green extraction methods using a combination of environmentally friendly mechanical, enzymatic, and chemical treatments were evaluated for the sequential extraction of carotenoid pigments, proteins, and chitin from the by-products of crab processing. Three high-value by-products were obtained from snow crab: pigmented vegetable oil, pigmented protein powder, and chitin. The results of the crab by-product characterization studies demonstrate that, with further optimization and scale-up studies, green extraction methods can offer effective, environmentally friendly, and safer alternatives to traditional, chemically intensive approaches for the valorization of snow crab processing by-products.
