Almadraba is a fishing art whereby a labyrinth of nets intercept the migratory movements of the large tuna, when they cross the Gibraltar Straits. This study, undertaken by AZTI-Tecnalia, involved analysing the chain of marketing of the tuna fish, from the catch in the almadrabas to its freezing - the aim being to design a monitoring system adapted to this mode of fishing -, to its handling and processing and to the first stages of marketing the product. The end target is the design of an identifying label that enables the association of the product with the monitored information.
Until now, most of the work has been concentrated on the FRIALBA frozen fish plant, in Barbate (Cádiz), recently built with the aim of improving the handling and preparation processes for red tuna for its subsequent marketing. The tuna arrives at the plant directly from the almadrabas and here classification, topping, gutting and cutting up takes place. The fillets are extracted and frozen at -60ºC for their subsequent marketings, both on the national market and on the Japanese one.
Japan is the largest market in the world for tuna (it absorbs 30% of the world’s production). The consumption there, basically aimed at the preparation of sashimi, has taken off in the past few years and, thus, imports as well. The sashimi market is, moreover, the most profitable in the world, given that the tuna can reach prices 30 times greater than that which will end up tinned.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
