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.
