Cruise of FF ”Walther Herwig III” 01.06.04 – 21.06.04  Chief scientist : Dr. Horst Karl  Studies on food safety and quality changes of fish  Summary:  Investigations of this cruise included studies of the influence of high pressure on the quality of fish fillets, the possible occurrence of tainting in herring  fillets as result of incorrect treatment during  CSW storage and  deep freezing and studies of  migration of nematode larvae in saithe fillets stored on ice. Fish samples for pollution studies on dioxin and dioxin like PCBs and inorganic contaminants were collected at different fishing grounds. Fish samples were monitored on the occurrence of Vibrio, Listeria and Enterobacteria   Narrative of cruise  FFS “ Walther Herwig III” (W.H. III) departed Bremerhaven  the 1st of June and started investigations next morning north of the German Bight. The progress of the cruise is summarised in table 1.  Date   Area of investigation Main fish samples taken 02.06.04 North of German Bight Plaice 03.06.04 Utsira  Ground, North sea Herring 04.06.04 Halibut Bank, Shetlands Saithe 05.06.04 Tampen, north of Shetlands Ocean perch, black halibut 06.06.04 West Orkneys area Various species 07.06.04 St. Kilda Varoius species 08.06.04 South-West of Hebrides Various species 09.06.04 West of Ireland Various species 10.06.04 South-West of Ireland Various species 11-12.06.04 Stop in Cork Ireland  13.06.04 Celtic Sea Herring 14.06.04 South of Irland Horse mackerel 15.06.04 Nymphe Bank Various species 16.06.04 N-West of Great Sole Bank Sardines 17.06.04 Eddystone Bay, England Various species 18.06.04 Lyme Bay, England Various species  On the afternoon of June 11th,  Walther Herwig III arrived at Cork in Ireland for a scientific information exchange with scientists from the Irish Sea Fisheries Board (BIM). W.H.III left Cork the next day, June 12th  and continued research work in the Celtic Sea east of Ireland and thereafter further work south on the shelf northwest of the Great Sole Bank. In the evening of June 18th fishing ended in the Lyme Bay  and  FFS “Walther Herwig III” returned to Bremerhaven on June 21st .     Preliminary results  A total of  52 hauls were made and samples of  60 different species of fish were collected and prepared for later species identification, analysis of essiential  elements and organic pollutants at land based laboratories. Special interest was focused on important fish species for the German market e.g. herring, mackerel, ocean perch etc.   Microbiological studies 50 fish and shell fish samples from various fishing grounds were analysed for the presence of Vibrio, Listeria monocytogenes and Enterobacteria.  Application of high pressure technology on fish The influence of isostatic high pressure on fresh fish fillets from 5 species was studies in terms of quality changes in relation to different rigor states.   Parasites in fish As part of the ongoing studies on nematodes in the muscle of fish for human consumption the possible  migration of nematodes in saithe fillets was studied with respect to conditions found in retail shops.  Tainting of herring fillets The aim of this study was to prove if incorrect treatment of herring during CSW storage and/or deep freezing can lead the development of off flavour in the fillets.
