The course of fisheries as per week 41/2018
Finally, a good week for mackerel, giving 52.000 MT with a value of more than 730 million NOK.
The North Sea herring reinvented. In close cooperation with the herring industry, Nofima has developed new, exciting products from the traditional fish.

Currently several different products are made from North Sea
herring, where Matjes herring is the most famous. The Netherlands
has been an important market, but in recent years Matjes
consumption has stagnated in the Netherlands. In recent years
production has sometimes exceeded consumption, which has caused
stocks to pile up. This is happening while North Sea herring stocks
are stronger than in a long time. Access to high quality raw
material has therefore constantly improved.
Renewal of process and product
The North Sea herring is a high quality raw material. It has a high level of freshness, a fat content of up to 20% and a very delicate texture, and is very well suited for producing lightly salted herring products. Nofima has therefore looked into opportunities to develop new products from this raw material.
By developing new processing methods, researchers have preserved
the raw material's excellent taste and texture properties, while
developing new market-adapted products. Development of the product
has taken place in close cooperation with the industry, and with
funding from the Norwegian Seafood Research Fund.
Small and fat
The result was Virgin herring. The name originates from the Dutch Matjes herring. Matjes is derived from the Dutch word "maagd," which means virgin. The same raw material is used for Virgin herring as for Matjes herring; first class North Sea herring.
The herring used must have the right gut content of copepod and have a high fat content. The virginal aspect is related to the small size of the herring, which is to be spawning for the first time. The catches of Virgin herring and Matjes herring are smaller than ordinary herring catches. This is because the gut content, copepod, could cause the belly to rupture. High quality requirements toward the raw material entails an exceptionally short time from catch to delivery.
Produced from fillet
Based on trials conducted in the past two years, full-scale processes have been developed for the production of new fillet products. While Matjes herring is filleted after processing is completed, the new products can be produced directly from fillets - with or without skin. This is both more rational in terms of production, as well as more consumer-friendly. At the same time, valuable by-products are made available for further processing to meal and oil, and transport costs are reduced.
Trials started on a small scale by investigating what the most important factors were to achieve the maturing that takes place in the Matjes process. Several interesting connections were uncovered, and methods were developed to adapt the products' taste and texture properties to the markets' desires and needs. In the summer of 2013 processes were upscaled to industrial scale.
Herring that people will want?
In market terms, Virgin herring has several potential competitive advantages. Consumers want uncomplicated products with less salt. As Virgin herring is filleted and lightly salted compared to most other traditional herring products, it is in keeping with consumer desires in several areas.
We also see that the traditional herring products that are strong in flavour lack appeal among younger consumers. In the Virgin herring products, new processes ensure that one can make products with a milder "Matjes flavour" that can be tailored to the preferences of younger consumers.
Currently work is ongoing on testing the products with leading manufacturers in several markets. Feedback from the market evaluations will be decisive for further adjustment and development of the processes and products, and one aims to launch the products for industrial customers and the HoReCa sector (hotel, restaurant and catering) after the year's season.
Unusual little of mackerel last week. Better for the North Sea herring – and some sprat and horse mackerel.
Better for the North Sea herring, some horse mackerel for consumption. Still scares of coastal mackerel and “Svanaug Elise” is heading for the Norwegian Sea.
New prices from September 3th 2018
Still difficult conditions for the North Sea herring, - though, the best week so far with more than 20.000 MT registered.
The North Sea herring is still widespread, – and miserable weather condition for the mackerel up north.
An even week for the North Sea herring, a little better for mackerel up north, - and the sand eel season is over.
