Frá árinu 2001 hefur bleikju stöðugt verið að fækka í Eyjafjarðará. Á sama tíma hefur urriða fjölgað nokkuð. Stangveiðimenn og landeigendur höfðu áhyggjur af þessu og var árið 2007 ákveðið að takmarka mjög veiðar á bleikju í ánni. Veiðar í hliðarám voru bannaðar, veiðitími styttur á efri svæðum og kvóti settur á bleikju. Eyjafjarðará er því með fyrstu ám á Íslandi sem kvótasetja bleikju. Litlar sem engar rannsóknir hafa verið gerðar á áhrifum veiða&sleppa á bleikju. Því var ákveðið að hrinda slíkri rannsókn í gang við Eyjafjarðará. Í stuttu máli gengur hún út á að nokkrir veiðimenn á svæðinu eru vopnaðir merkibyssum og merkja allan fisk sem þeir sleppa. Niðurstaðan er svo hversu mikið af fiski endurveiðist. Treyst er á að stangveiðimenn skili inn upplýsingum um merkta fiska sem þeir veiða. Ýmist með þvi að skrá í veiðibækur, hafa beint samband við merkingamann, hafa samband við Fiskistofu eða skilað í hreisturpoka. Mest hefur verið skráð í veiðibækur. Athygli vakti að nokkrir af aflahæstu veiðimönnunum í Eyjafjarðará skráðu ekki einn einasta endurveiddan merktan fisk meðan aðrir, sem jafnvel veiddu færri fiska, skiluðu upplýsingum um nokkra endurveidda merkta fiska. Þetta var raunin ekki bara eitt veiðitímabil – heldur nokkur tímabil. Óljóst er hvað þeim gengur til með því. Þegar þetta er skrifað (ágúst 2013) hafa verið merktir um 1500 fiskar í 12 ám. Hér má sjá töflu yfir endurheimtur eftir tegundum á veiðiám. Hafa ber í huga að endurveiðihlutfall ákvarðast ekki bara af lifun fiskjar, heldur einnig af veiðihlutfalli. Rannsóknir benda til að veiðihlutfall á laxi sé nærri 70% en það er heldur óljósara á bleikju, sennilega afar breytilegt og gæti verið 20%-60%. – með áherslu á “gæti verið”. Við hvetjum alla veiðimenn til að skila inn upplýsingum um merktan fisk. Einnig vantar okkur, til aldursgreiningar, hausa af drepnum fiski, ásamt hefðbundum veiðibókarupplýsingum (lengd/þyngd, staður/stund, kyn/tegund, veiðimaður/agn).
