    • Oppfatninger om og holdninger til reguleringer blant kystfiskere med rettigheter i torskefiske 

      Aarset, Bernt (Rapport, Research report, 2006-12)
      Det er en forutsetning i moderne norsk fiskeriforvaltning at regelverk og direktiver virker. Denne rapporten drøfter betingelsene for at disse skal virke uten at tvangs- og kontrollmidler tas i bruk i fullt monn. Dette ...
