Quality and quality management are of increasing concern and importance in all parts of the fishery
chain. Fishing gears and handling onboard the vessel have multiple impacts on fish quality, and damages
caused during these operations may affect the product quality considerably, resulting in downgrading of
the end products. The European fish sector consider measurement of quality defects and other quality
factors as important, but methods for systematic evaluation of quality defects caused during catching
operations have not been published to any extent.
In this work cod caught by different fishing gears commonly used in the Norwegian coastal fisheries
were examined for catch-related damages at landing. Other species like saithe and haddock may suffer
the same damages, but due to being the economically most important specie in Norway, cod is chosen as
model. The severities of the damages are described, and the influence of the damages on the quality of
cod products is considered. Based on this, a Catch-damage-index (CDI) scheme is elaborated.
