Brisling- og sildeundersøkelser i fjordene, 1. November - 11. Desember 1996 / E. Torstensen, J. Røttingen, K.E. Jørstad.
Title: | Brisling- og sildeundersøkelser i fjordene, 1. November - 11. Desember 1996 / E. Torstensen, J. Røttingen, K.E. Jørstad. |
Translated title: | Sprat and herring research in the fjords, 1st Nov. - 11th Dec. 1996. |
Author(s): | Torstensen, E. Røttingen, J. Jørstad, K. E. |
Date: | 1997. |
Language: | Norwegian. |
In: | Fisken og Havet. (1997.), Vol. 15 (1997) |
Abstract: | Since 1968 fjords from Ryfylke to Finnmark have been surveyed acoustically to obtain indices of abundance of 0-group sprat and Norwegian spring spawning herring. There was strong increase in estimates of herring in fjords in Nordland-Finnmark from 1995. Genetic analyses used LDH-2in assessing population structure. Mixtures with local fjord herring were found in several areas. Both species were examined for fungus Ichthyophonus hoferi. Infection rate was low: 1/1053 sprats, 7/985 herring. |
