Factors influencing production loss in salmonid farming

Using a unique dataset, this paper investigates factors influencing production loss in Norwegian salmonid farming. The can be grouped into fish-specific (e.g. species, genetics, and generation), input vaccines smolt quality), environmental geographical location), managerial ownership). most important result is likely that losses to large extent are explainable, as our best model has an R2 high 0.826. This implies it possibile reduce significantly. For the specific factors, loss, but their effect varies by site. Production also with which plant providing juvenile fish, indicating there systematic quality variation among providers of smolt. There significant between companies sites, on average lower for larger sea sites holding numbers fish. An point while some explaining controlled individual company, others beyond control. Some these external related regulatory system.
