In the late 80s a number of processing lines made by the Swedish firm VMK and the German Baader were installed on Russian vessels. This was followed by a pause where few Russian vessels were overhauled. Now however, according to Ulf Groenqvist of Seac AB, there seems to be a small boom in the number of Russian and Ukrainian factory vessels that are being refurbished. These boats are being upgraded with either new or completely renovated processing machinery.

Fish and seafood are today transported around the globe by road, sea and air. Whilst transporting durable products such as canned or salted foods is relatively easy, fresh and frozen products make considerably more demands on the carrier. It’s live fish that present the really big challenge, however. Their transport is expensive and difficult, but to make up it enables top freshness and quality.

In 1976 the independent sales representative Rudolf Maass founded in co-operation with Adolf Cavier the company Rudolf Maass + Partner KG in Hamburg. His vision was the development and production of a salmon slicer for industrial use. This was the genesis of the Maass Salmon Slicer CM 176. Through constant, intensive co-operation between producer and customers, the company’s range of slicers grew rapidly.

“Fish slaughter” can be understood in different ways: It generally comprises preparatory measures for the slaughter process, then the stunning and actual killing of the fishes, as well as gutting. In the past the focus was primarily on efficiency and profitability. Today, efforts are also made to avoid unnecessary stress for the fishes. This applies both to manual and machine slaughter processes.

The market for plate freezers has always been fiercely competitive. Over the last years, however, with the entry on to the market of Asian companies that can produce equipment at lower costs than their European counterparts, the focus has moved to innovation, reliability, and customer service.

Skagerak Salmon, part of the Skagerak Group, specialises in salmon products both semi-processed, but also increasingly portions for the retail market and more value-added products. About 60% of the production is fresh fish while the rest is frozen.

Polylactic acid (PLA) is a compound derived from renewable resources such as corn starch, sugarcane, or tapioca that can be used for the manufacture of plastic packaging materials that have several advantages over plastics produced from oil. Among the companies that are using this material is Depron, a manufacturer of packaging materials based in the Netherlands.

Seac AB, the Swedish company specialised in renovated processing machinery for the fish industry, will launch the FPM-400, a new nobbing and filleting machine, at Seafood Processing Europe in April.

The fishing industry in Iceland has learned that adding ever more value to the resource is the only way to compensate for dwindling fish catches. This pursuit for greater value has led to the development of a vast and diverse ancillary industry on Iceland dedicated to developing and implementing methods that increase the returns from the raw material. Vessel design, catching gear, storage and transport, processing machinery, and biotechnology, are some of the areas that have developed in Iceland as a result of the fishing industry.

Fish quality is directly related to the temperature at which it is stored. Deterioration of the product starts immediately upon the death of the animal and from then on can not be reversed, but only arrested. Keeping product at the correct temperature is crucial to bringing the process of deterioration almost to a standstill, thereby maintaining quality. A substantial body of scientific literature has proven the direct link between the temperature at which the product is maintained and its shelf life. If the integrity of the cool chain is compromised even briefly, this will influence the shelf life of the product.
