Acoustic investigations have been carried out in selected fjords from Ryfylke to Finnmark to map the occurrence of herring and sprat. Recorded concentrations have been sampled with pelagic trawl. All samples have been tested for occurrence of the fungus Ichthyophonus hofen, and a number of samples have been taken for testing of genetical variation.NORSK SAMMENDRAG:Rapporten beskriver resultatene fra en akustisk kartlegging av brisling og 0- og 1- gruppe sild i utvalgte fjorder fra Ryfylke til Finnmark i november-desember 1994. Mengden av 0-gruppe brisling var ca. en tredjedel av det som ble målt i 1993. Reduksjonen var spesielt sterk i Hardanger og Sogn, mens det i Nordfjord ble målt mer 0- gruppe brisling. Eldre brisling utgjorde e...
