Prevention of fish rankness and quality loss consists in reducing susceptibility to oxidation through the production of an oxygen barrier by glazing and the addition of hydroxythyrosol as a natural water-soluble antioxidant. The technique is also applicable to fish and crustacean products. More detailed information can be found here.

The invention relates to a method of preserving live shellfish using a modified atmosphere that is rich in oxygen and contains a second main nitrogen component, so as to preserve live bivalve shellfish and safeguard their quality for as long as possible throughout the whole marketing and sale process. The commercial shellfish packaging must be full and well compacted, for which purpose units must be perfectly inserted during the filling operation using a vibrator so that bivalve shellfish cannot open their valves, thus losing intervalvar liquid, throughout the marketing process. The invention relates to the most popular bivalve on the market in terms of sales and price and, as a result, is of particular interest to the mussel industry. More detailed information can be obtained here.

Technique for the preparation of hyaluronic acid (AH) based on fish vitreous humor for its use in cosmetics and clinical work. The process comprises protein electrodeposition and simultaneous diafiltration with total recirculation. This procedure allows for selective recovery of impure sediments, precipitation of AH and solubilization of proteins, yielding AH with purity over 99.5%. More detailed information can be found here.

Technique for the identification of Thunnus alalunga in preserved tuna products, which comprises the amplification of a 187-pb fragment (BDR) of the cytochrome b gene in mitochondrial DNA by the sequential use of two endonucleases. This allows distinguishing it from other species used as substitutes for Thunnus alalunga in canned products. More detailed information can be found here.

Technique for the identification of Auxis thazard in preserved fish products, which consists of the amplification of a 187-pb fragment (BDR) of the cytochrome b gene in mitochondrial DNA by the use of a restriction endonuclease. This allows distinguishing it from other species used as substitutes for Auxis thazard. More detailed information can found here.

Technique for the differentiation of various tuna species in canned tuna products, consisting of the sequential use of a set of restriction endonucleases on an amplified 187-bp fragment known as bdr of the b cytochrome in the mitochondrial ADN. Thus, Thunnus thynnus, T. obesus, T. albacares and Katsuwonus pelamis are distinguished by fragment analysis. More detailed information can be found here.

Development of Deep Learning algorithms that allow automating fisheries monitoring processes and reducing time and costs compared with processing by human observers. The applications developed range from innovative systems for real-time remote electronic monitoring, which identify and quantify total catches of fishing vessels (e.g., iObserver), to new image recognition techniques that allow individually identifying fish and estimating population parameters. 

MIDER (mutual information distance and entropy reduction) is a general purpose software tool for inferring network structures. It has been developed with biological networks in mind but can be applied to other areas.
