Monitoring of external pathologies of fish in the Barents Sea: Methods and results

The results of the study carried out in 1999-2011 have been presented. The aim was to evaluate the health of commercial fish and the quality of environment in the Barents Sea and adjacent waters. External pathologies studied by morphological, pathomorphological and histiopathological methods have been used as bioindicators. It has been revealed that pathologies annually registered in fish of the Barents Sea refer to six groups, including tumors. The average prevalence of pathologies in fish was 0,7 %. During last 3 years eye pathologies were dominant and their fraction in the variety of revealed pathologies reached 97,5 %.

The efficiency of the protein hydrolyzates, complexes of phospholipids, carotenoids, chitosan and other food ingredients derived from the fish processing waste or low commercial value fish species (polar cod, blue whiting etc.), and the waste of meal production such as the wheat germs in the combined feeds has been investigated. The prospects for ongrowing salmon, whitefish, cod fish juveniles and invertebrates in the Barents Sea inlets using combined feeds worked out in PINRO have been shown.
