Catfish. Catch, markets, utilization and chemical content / Atlantic wolffish. Icelandic catch volumes, markets, yield and chemical content

The report is a brief overview of the state of the knowledge available today on the catch volume, life pattern, utilization and chemical content of catfish caught in Iceland. The Marine Research Institute has been working on research into the distribution and life pattern of catfish in the sea around Iceland. Statistics Iceland's statistics show developments in, among other things, fishing and the disposal of catfish catches. Knowledge of the variability in the processing properties and chemical content of the fish is limited and nothing was found about the stability of catfish products during storage. The research based on utilization and chemical content is based on older data from IFL (now Matís ohf) from around 1980. They show that, as with other species, the condition of the fish is highly dependent on the time of spawning and the time of year. What makes catfish different from more common species such as cod is that it loses teeth during spawning and guards its eggs which inhibits food acquisition.

This report is a broad literature review about catch volumes, reproduction, yield and chemical content of Atlantic wolffish caught in Icelandic waters. The Icelandic Marine Institute has investigated the distribution, growth, maturity and fecundity of the fish and the Icelandic Statistics collects and produces statistics on fish catch, manufactured products and exports. Information about the variability in yield and chemical content of wolffish are limited and knowledge about the stability and degradation process of wolffish products is limited.

A big day at Matís - The new house will be a revolution for the business

This morning Matís ohf. delivered new premises at Vínlandsleið 12. Mótás hf. built the house and furnished it according to Matís' needs.

Matís' operations in Reykjavík have been in 3 locations but will now be merged under one roof and this will be a great streamlining of operations.

"This change will be a revolution for Matís and the company's operations. We are merging operations that are currently in three locations in Reykjavík under one roof. At the same time, it will be a great change and strength for our offices around the country to now be able to have their backing under the same roof in Reykjavík, "says Sjöfn Sigurgísladóttir, CEO of Matís.

The merger in one place lays the foundation for an even stronger work for the research company Matís, and the CEO says that it can be important for innovative projects in the field of the food industry.

"I have no doubt that we are already seeing the results of our emphasis on increasing Matís' collaboration with universities and the business community. This supports innovation in fisheries and agriculture, but also innovations such as food-related tourism, for example. The business community is constantly perceiving better opportunities in research and that is precisely why I welcome the fact that we are enabled to grow with new headquarters when it is important for the national economy to promote innovation, "says Sjöfn Sigurgísladóttir, CEO of Matís.

In the next few days, the new building will be moved and operations there will be fully operational in early January 2010.

Matís thanks Mótás hf. for a very successful collaboration at this time.

Service measurements

From 14 to 23 December 2009, Matís' operations in Reykjavík will move to new shared premises at Vínlandsleið 12 in Grafarholt. Due to the relocation, it will not be possible to receive samples for microbial and service measurements in Reykjavík during this period.

Customers are kindly requested to schedule sampling projects so that they do not fall within the specified transfer dates. If there is an urgent need, we can provide our customers with certain microbial and chemical measurements at our laboratory in Neskaupstaður or at other accredited laboratories that we use as subcontractors during the transfer period.

It is expected that the operation of the service measurements will return to normal as early as the beginning of January next year. As soon as we apologize for any inconvenience our business partners may have from this temporary disruption to Matís 'service measurement operations, we would like to extend a warm welcome to you for your continued business and cooperation in Matís' new and magnificent headquarters.

On behalf of Matís' service measurement staff,

Mackerel processing in Icelandic fishing vessels

The fishing year 2004/2005 was the first recorded mackerel catch in Icelandic jurisdiction, since then the catch has increased from year to year but in the fishing year 2008/2009 a catch was set, then 100,000 tonnes of mackerel could be caught with Norwegian-Icelandic herring in Icelandic jurisdiction.

The mackerel has mainly been caught in July and August off the coast of Iceland, but in the summer of 2009 Icelandic vessels began to catch mackerel with herring in June and caught mackerel until September. For the next fishing year, 130 thousand tonnes of mackerel have been allocated. 

In order to be able to process mackerel on board Icelandic fishing vessels, they must have certain equipment, first there must be a sorter that sorts the mackerel from the herring. Style classifiers have proven to be good in that respect, but it is also possible to classify the mackerel in that equipment. The traditional processing line used for processing and freezing herring needs to be changed so that the mackerel can be decapitated and gutted before it is frozen. The market is mainly for decapitated and gutted mackerel, as its shelf life is the most.

It is important to be able to classify the mackerel from the Norwegian-Icelandic herring when the species in question are caught together to create the most value from the catch, instead of sending a large part of the mackerel-mixed herring catch for smelting. Numerous experiments have been made with the classification of the species and they have been successful, whether in the processing of only one species or both at a time.

Crowds at a meeting of Matís, AVS and SF about opportunities in the Icelandic fisheries sector

An interesting meeting on opportunities in the Icelandic fisheries sector has just ended, a meeting hosted by Matís, the AVS Fund and the Association of Fish Processing Plants.

The meeting was well attended and about 160 people came to listen to the speeches of Þorsteinn Már Baldvinsson, CEO of Samherji, and Sveinn Margeirsson, division manager at Matís.

The aim of the meeting was to shed light on opportunities and possibilities for better utilization and increased value. Icelanders are at the forefront of the utilization of marine resources and have strong and powerful fisheries companies with years of experience in meeting the needs of the market. But our raw material is a limited resource and therefore it is necessary to make the best use of it and create great value from it.

Þorsteinn Már's speech can be found here and Sveinn's talk can be found here.

For further information, please contact Sveinn Margeirsson, sveinn.margeirsson@matis.is, and Steinar B. Aðalbjörnsson, steinar.b.adalbjornsson@matis.is.

Ichthyophonus hoferi herring and other fishes / Ichthyophonus hoferi in infected herring and other fishes

The aim of the project was to set up a simple DNA analysis method to detect the parasite Ichthyophonus hoferi in infected fish and to check if there is a difference between the parasite found in herring and plaice in Iceland. The intention was also to investigate whether I. hoferi was found in cod that had eaten infected herring, both fresh and salted fish. The objectives of the project were achieved, but the method development was more extensive than expected in the application. In this project, technology was developed for the genetic analysis of the Ihoferi infection in herring and plaice in Iceland. Methods based on conventional PCR and sequencing were tested and developed, in fact time PCR but also genetic analysis with the size analysis of the 18S mark, but to the best of our knowledge, the latter two methods have not been used before to analyze the I. hoferi. The method can be used both to diagnose infection in blood-rich organs such as the heart and kidneys but also in infected flesh. The cod could not be detected in cod. In the future, the method can be used for further research into the infection to try to shed light on the extent and extent of the infection and to try to identify the origin of the infection by applying the method to the different food types of herring.

The goal of the project was to develop a genetic analysis method to diagnose if the parasite Ichthyophonus hoferi was found in herring and other fish species. Furthermore, to determine if the same parasite species was infecting herring and infecting European plaice (Pleuronectes platessa) in Icelandic waters. Another goal was to analyze if I. hoferi could be found in cod (Gadus morhua) either salted or fresh which had been caught from infected herring areas during 2009. The goal of the project was reached and four different genetic methods were tested and all were successful. Conventional PCR technique as well as sequencing was used in the project. Real-time PCR and genotyping on ABI3730 sequencing machine were also developed successfully. The most sensitive technique is the last one (genotyping on ABI3730). The last two methods have not been published to our knowledge in this purpose. We detected I. hoferi parasite both in hearts, kidneys and fresh fillets of the fish. The parasite could not be detected in cod. In future studies, these techniques may be used for research of the origin of the parasite in the herring feed and to determine the distribution of the parasite.

Isolation, purification and investigation of peptides from fish proteins with blood pressure decreasing properties / Isolation, purification and research on blood pressure lowering peptides from fish proteins

The aim of the project was to study the activity of fish peptides and to isolate, purify and define peptides that have an antihypertensive effect. The project set up facilities and knowledge acquired so far by Matis. This includes a method for measuring ACE inhibitory activity as well as peptide isolation and purification equipment. In collaboration with the University of Iceland, HPLC and Maldi-Tof equipment were used to analyze which peptides were in the active components. The results of the project show that Icelandic fish protein could be an important source of peptides with antihypertensive properties. With the knowledge and facilities that have been acquired in the project, it is possible to develop valuable fish products and health food.

The aim of this project was to study the activity of fish proteins and isolate, clarify and define peptides with antihypertensive properties. During the project time methods and equipment to be able to do this were set up at Matis facilities. This includes method to measure ACE inhibition activity as well as filtration and fractionation units to isolate different fractions of peptides. Furthermore, peptides have been identified in the most active fraction by using HPLC and Maldi-ToF equipment in collaboration with the University of Iceland. With this extensive tool box of know-how, equipment and facilities, development of valuable fish products and nutraceuticals from blood pressure-lowering peptides is possible. Thereby the value of the Icelandic natural resources in the sea can be increased.
