Hummerfisket 2017 og 2018: Innsats og fangst

Abstract

I 2017 ble det innført obligatorisk påmelding til hummerfisket for både fritidsfiskere og yrkesfiskere. Dette har lagt grunnlaget for muligheten til å beregne total innsats og fangst av hummer i Norge. Etter hummersesongen 2017 ble det gjennomført en etterundersøkelse av et tilfeldig utvalg av de påmeldte som en pilotstudie for datainnsamling. I 2018 ble et tilfeldig utvalg påmeldte fiskere kontaktet ved starten av hummerfisket og bedt om å rapportere alle sine fisketurer gjennom sesong. Resultatene fra 2017 og 2018 er ikke direkte sammenlignbare da det er benyttet to ulike metoder. I 2017 var det påmeldt 36 393 fiskere, mens det var totalt påmeldt 29 681 fiskere i 2018. En nedgang på 18 %. Årsaken til denne nedgangen er ikke kjent. I 2017 landet hver påmeldt fritidsfisker som deltok i hummerfisket i snitt 12 (95% CI=2,3) hummer med små regionale forskjeller. I 2018 ble det landet 10,9 (CI=1,5) hummer per påmeldte fritidsfiskersom deltok i fisket. Yrkesfiskerne landet i snitt 75 (95% CI=15) hummer hver i 2017 og 66 (95% CI=8) i 2018. Totalt for 2017 er det beregnet at fritidsfiskerne landet 321 000 hummer (95% CI; 260 000 - 381 000) og yrkesfiskerne landet 133 000 hummer (95% CI; 107 500 - 158 700). Totalt ble det da landet rundt 454 000 hummer i 2017. For 2018 er det beregnet at fritidsfiskerne landet totalt 227 000 (95% CI; 194 000 – 260 000), mens yrkesfiskerne landet 95 000 (95% CI; 61 000 – 128 000) hummer. Totalt ble det da landet rundt 322 000 hummer i 2018. I 2017 utgjorde fritidsfiskerne 71 % av landingene og i 2018 70 %. Fritidsfisket dominerer uttaket i alle tre regioner (Skagerrak, Vestlandet og Nord-Vestlandet).
