ITQs are transferred from one vessel to another throughout the year in terms of ups and downs and the different opportunities that arise: damage to a vessel, a boss who ceases his activities, a fishermen who operates in Denmark where more plaice can be found and who would like to obtain more quotas on this species by giving up his quotas for sole, and so on.
Déantar CAI a aistriú ó bhád go chéile i rith an ama le linn na bliana, de réir chora an tsaoil agus de réir na ndeiseanna sin a thagann chun cinn: bád a bhriseann síos, ceannasaí a shocraíonn deireadh a chur lena chuid gníomhaíochta, iascaire a d’aistrigh chuig an Danmhairg, áit a bhfuil níos mó leathóg le fáil, agus ar mhian leis tuilleadh cuótaí a bheith aige don speiceas seo, trí thabhairt suas dá chuid cuótaí sóil, srl.
