Hvor stor er gennemsnits-havørreden på kysten?

Baseret på data i Fangstjournalen er en gennemsnitlig kystørred få cm over mindstemålet.

Gennemsnitsstørrelsen af alle kyst-havørreder, indrapporteret af I brugere i hele 2017, var helt præcist 41,7 cm. For havørreder over 40 cm var gennemsnitsstørrelsen derimod 49,7 cm.

Længden på genudsatte fisk er selvfølgelig baseret på brugernes skøn, hvilket giver en usikkerhed. Kigger vi alene på hjemtagne fisk, som formodentlig er målt med større præcision, er

gennemsnitslængden 49,1 cm.

Udenlandske studier har vist, at jo længere tid, der går inden man registrerer sin fangst, jo mere er man tilbøjelig til at huske forkert – eller endnu værre - helt glemme at føre journal over sin fisketur. Sjovt nok så peger foreløbige analyser fra Fangstjournalen i samme retning:

Her kan vi se, at gennemsnitslængden af havørreder, som er indrapporteret ”live” under en fisketur, konsekvent er lidt mindre end længderne af havørreder, som er indberettet fra sofaen efter

fisketuren er slut.

K&B derude 👍🎣
