Når blommesæklarverne selv begynder at indtage føde, går de til <b>Larvestadiet</b>. Larverne betegnes <b>Leptocephali</b>, da man tidligere troede, det var en selvstændig art ved navn <i>leptocephalus brevirostris</i>. Leptocephali er transparente (gennemskinnelige) og har form som et pileblad. Alt tyder på, at de indtager næring fra plankton, men det er ikke bevist. Larverne driver med <a href="/wiki/Golfstr%C3%B8mmen" title="Golfstrømmen">Golfstrømmen</a> og den <a href="/wiki/Nordatlantiske_str%C3%B8m" title="Nordatlantiske strøm">nordatlantiske strøm</a> til Europas og Nordafrikas kyster, hvor de forlader deres <a href="/wiki/Pelagisk_flora_og_fauna" title="Pelagisk flora og fauna">pelagiske</a> eksistens og søger op i floder og mindre vandløb. Driften tager mellem 1-2 år, og i den periode når ålelarverne en længde på cirka 7,5 centimeter. Fremme ved Europas kyster forvandles larverne til <b>Glasål</b>, der stadig er transparente, men deres pigmentering udvikles så småt. De første tegn på knoglestruktur bliver synlig. Ålene ændrer i dette stadium fødevalg til at omfatte små insektlarver og orme. Glasålen er yderst lysfølsom på grund af dens manglende pigmentering. Glasålen forvandles nu til en <b>Gulål</b>. Den lever som gulål i 6-16 år, det vil sige det meste af livet. I det stadium lever den af insekter, orme, bløddyr og mindre fisk. Det er vigtigt for den at lagre store fedtreserver, da den, efter at have forvandlet sig til en <b>Blankål</b>, mister evnen til at spise og således ikke indtager føde undervejs tilbage til gydepladserne i Sargassohavet. Blankål-stadiet er interessant, da ålen gennemgår markante fysiologiske ændringer. Ud over at stoppe med at æde omstiller den sig fra livet i ferskvand til rejsen i saltvand. Når fisk udsættes for et sådant skift, skal de ved hjælp af interne mekanismer afbalancere saltet i deres organisme.

Hovedmålet var at mindske menneskeskabte miljøpåvirkninger af ålens levesteder og sætte ind over for overfiskeri. Unionen tilstræber, at opnå en en bestand af ål på mindst 40 % af det estimerede antal før ålens tilbagegang begyndte. Antallet af ål, der forlader vandløbene og vandrer tilbage til Sargassohavet for at gyde, skal øges. Håbet er at stoppe den negative tendens, hvor mængden af glasål er faldende som følge af, at færre blankål vender tilbage for at gyde. Danmark og EU's andre medlemslande har udarbejdet en genopretningsplan for den europæiske ål. Den 1. juli 2009 blev der gennemført en række stramninger på området inden for erhvervsfiskeri af ål. Siden den 31. december 2012 har det bl.a. resulteret i: </p> <ul><li>Reducering af kommercielt fiskeri.</li> <li>Begrænsning af fritidsfiskeri.</li> <li>Regler om genudsætning.</li> <li>Forbedring af ålens levesteder i vandløbene samt arbejde med at lette ålens passage af spærringer ved spærringer som vandkraftværker og vandmøller.</li> <li>Transport af blankål til steder, hvorfra de frit kan svømme til Sargassohavet.</li> <li>Perioder, hvor turbinerne i vandkraftværker, ikke kører – i den periode, hvor ålene vandrer.</li></ul> <div class="mw-heading mw-heading2"><h2 id="Akvakultur">Akvakultur</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Europ%C3%A6isk_%C3%A5l&veaction=edit&section=5" title="Redigér afsnit: Akvakultur" class="mw-editsection-visualeditor"><span>redigér</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Europ%C3%A6isk_%C3%A5l&action=edit&section=5" title="Edit section's source code: Akvakultur"><span>rediger kildetekst</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Opdræt af den europæiske ål i <a href="/wiki/Akvakultur_(vandlevende_organismer)" title="Akvakultur (vandlevende organismer)">akvakultur</a> startede for cirka 30 år siden.

Glasål har en høj tilpasningsevne, som udnyttes til gradvist at vænne dem til foderpiller med højt energiindhold. Glasål i akvakultur har generelt færre parasitter og sygdomme end ål i mere udviklede stadier. Derudover kan glasål leve på meget lidt plads. Der går omkring 2,5 kilo glasål til opdræt af 1 ton voksne gulål. Et kilo glasål svarer til 2.800-3.300 individer. </p><p>I 2008 blev der fanget omkring 150 tons glasål over hele Europa, hvoraf omkring 100 tons gik til akvakultur og resten til konsum eller genudsætning (Nielsen, 2008). Et problem for akvakulturen er, at den europæiske ål ikke gyder i fangenskab.
