A delfinek h\u00e1l\u00f3fosztogat\u00f3 technik\u00e1ja<\/h2>\n\n

A delfinek megtanult\u00e1k, hogy \u00e9szrev\u00e9tlen\u00fcl behatolnak az \u00f3ri\u00e1si h\u00e1l\u00f3kba, amelyeket a fen\u00e9k ment\u00e9n h\u00faznak, hogy halat fogjanak. A h\u00e1l\u00f3ba jutva lakm\u00e1roznak a csapd\u00e1ba esett halakb\u00f3l. Viselked\u00e9s\u00fcket vil\u00e1gszerte megfigyelt\u00e9k, t\u00f6bbek k\u00f6z\u00f6tt a Mexik\u00f3i-\u00f6b\u00f6lben \u00e9s a F\u00f6ldk\u00f6zi-tengeren.<\/p>\n\n

B\u00e1r ez a vad\u00e1sztechnika gazdag t\u00e1pl\u00e1l\u00e9kforr\u00e1st biztos\u00edt a delfinek sz\u00e1m\u00e1ra, vesz\u00e9lyekkel is j\u00e1r. A delfinek a h\u00e1l\u00f3ba gabalyodva megfulladhatnak. A kutat\u00f3k becsl\u00e9se szerint \u00e9vente t\u00f6bb ezer delfin pusztul el mell\u00e9kfog\u00e1sk\u00e9nt a trallerek h\u00e1l\u00f3iban.<\/p>\n\n

Kutat\u00e1si eredm\u00e9nyek<\/h2>\n\n

A leg\u00fajabb kutat\u00e1sok f\u00e9nyt der\u00edtettek a delfineket h\u00e1l\u00f3ba csalogat\u00f3 viselked\u00e9sre. A trallerek k\u00f6r\u00fcli delfinmozg\u00e1sok tanulm\u00e1nyoz\u00e1s\u00e1val a tud\u00f3sok arra a k\u00f6vetkeztet\u00e9sre jutottak, hogy az \u00e1llatok sz\u00e1nd\u00e9kosan l\u00e9pnek be a h\u00e1l\u00f3ba, hogy t\u00e1pl\u00e1l\u00e9kot keressenek. Nem csup\u00e1n v\u00e9letlen\u00fcl gabalyodnak bele a fen\u00e9k ment\u00e9n h\u00fazott h\u00e1l\u00f3ba.<\/p>\n\n

A felfedez\u00e9s, hogy a delfinek sz\u00e1ntsz\u00e1nd\u00e9kkal \u00fasznak a trallerek h\u00e1l\u00f3j\u00e1ba, jelent\u0151s v\u00e9delmi vonatkoz\u00e1sokkal b\u00edr. Azt sugallja, hogy a h\u00e1l\u00f3k m\u00f3dos\u00edt\u00e1s\u00e1val cs\u00f6kkenteni lehet a delfinmell\u00e9kfog\u00e1st an\u00e9lk\u00fcl, hogy cs\u00f6kkenne a hal\u00e1szat hat\u00e9konys\u00e1ga.<\/p>\n\n

Egy lehets\u00e9ges megold\u00e1s menek\u00fcl\u0151ny\u00edl\u00e1sok felszerel\u00e9se a h\u00e1l\u00f3kra, amelyek el\u00e9g nagyok a delfinek sz\u00e1m\u00e1ra, de a halak nem tudnak kijutni rajtuk. Egy m\u00e1sik lehet\u0151s\u00e9g akusztikus riaszt\u00f3k alkalmaz\u00e1sa, amelyek t\u00e1vol tartj\u00e1k a delfineket a h\u00e1l\u00f3kt\u00f3l. Ezeknek az int\u00e9zked\u00e9seknek a bevezet\u00e9s\u00e9vel enyh\u00edteni lehet a tralerez\u00e9s delfinpopul\u00e1ci\u00f3kra gyakorolt hat\u00e1s\u00e1t.<\/p>\n\n
