Absorption term in time-varied-gain functions
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1981)A potential source of error in acoustic measurements of fish density is the absorption part of time-varied-gain functions. This should be determined from the 1977 Fisher and Simmons equation. Use of its predecessor, the ... -

Aggression and growth of Atlantic salmon parr. I. Different stocking densities and size groups
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1986)The aggressive behaviour and growth of salmon parr under crowded rearing conditions was studied at four different densities. One or several fish per aquarium was dominant, displaying a kind of territorial defence and ... -
