Hydro-acoustics, underwater cameras, herring and predator gillnet samples ... -
Impact of herring spawning behaviour on acoustic abundance estimates
Skaret, Georg; Fernö, Anders; Nøttestad, Leif; Johannessen, Arne; Axelsen, Bjørn Erik (ICES CM documents, Working paper, 2001)Spawning dynamics of Norwegian spring spawning herring was studied in south western Norway 29 March to 3 April 2000 using hydroacoustics.
