Vous avez probablement d\u00e9j\u00e0 entendu quelqu'un dire : \u00ab Il a une m\u00e9moire de poisson rouge ! \u00bb C'est une expression courante pour d\u00e9crire une tendance \u00e0 l'oubli. L'id\u00e9e a gagn\u00e9 en popularit\u00e9 apr\u00e8s la sortie du film Pixar. Le film \u00ab Le Monde de Nemo \u00bb, o\u00f9 le personnage de Dory souffre de pertes de m\u00e9moire \u00e0 court terme, a engendr\u00e9 la croyance r\u00e9pandue que les poissons ne se souviennent des choses que pendant trois secondes. Mais est-ce scientifiquement exact\u00a0? Des cr\u00e9atures ayant surv\u00e9cu pendant des millions d\u2019ann\u00e9es dans des \u00e9cosyst\u00e8mes complexes et dangereux peuvent-elles r\u00e9ellement vivre sans m\u00e9moire fonctionnelle\u00a0? Examinons les preuves scientifiques modernes qui d\u00e9montrent que\u2026 Les poissons sont beaucoup plus intelligents et plus conscients.<\/strong> plus que nous le pensions auparavant \u2014 et que le mythe de la faible m\u00e9moire des poissons ne refl\u00e8te absolument pas la v\u00e9ritable force de leur m\u00e9moire.<\/p>\n

Pourquoi les poissons ont-ils une m\u00e9moire si performante ?<\/h2>\n

La m\u00e9moire est essentielle \u00e0 la survie. Elle permet aux animaux de trouver de la nourriture, d'\u00e9viter les dangers et de reconna\u00eetre des lieux familiers ou d'autres cr\u00e9atures. Les poissons vivent dans de vastes \u00e9tendues d'eau libre peupl\u00e9es de pr\u00e9dateurs. Sans une m\u00e9moire d\u00e9faillante, ils ne survivraient pas une journ\u00e9e.
\nR\u00e9fl\u00e9chissez-y logiquement :
\nComment pourrait-on esp\u00e8ces de poissons<\/a> qui existent depuis plus de 500 millions d'ann\u00e9es<\/em> Comment continuer \u00e0 prosp\u00e9rer, \u00e0 migrer et \u00e0 se reproduire sans un syst\u00e8me de m\u00e9moire robuste ?<\/p>\n

Des exp\u00e9riences scientifiques r\u00e9v\u00e8lent la capacit\u00e9 de m\u00e9morisation des poissons<\/h2>\n

Voici plusieurs exemples fascinants qui d\u00e9montrent clairement que les poissons poss\u00e8dent une m\u00e9moire \u00e9tonnamment performante. Les scientifiques ont d\u00e9couvert de nombreuses fa\u00e7ons dont les poissons se souviennent, apprennent et s'adaptent, prouvant ainsi qu'ils sont bien plus intelligents que la plupart des gens ne le pensent.<\/p>\n

Exp\u00e9rience de m\u00e9moire spatiale<\/h3>\n

Dans une \u00e9tude bien connue, des chercheurs ont entra\u00een\u00e9 des poissons \u00e0 identifier l'endroit o\u00f9 la nourriture \u00e9tait plac\u00e9e. \u00e0 l'int\u00e9rieur d'un r\u00e9servoir<\/a> \u00e0 des moments pr\u00e9cis de la journ\u00e9e. M\u00eame apr\u00e8s une pause de deux semaines, les poissons se rassemblaient au m\u00eame endroit et \u00e0 la m\u00eame heure, s'attendant \u00e0 \u00eatre nourris, ce qui montre que Leur souvenir a dur\u00e9 des semaines<\/strong> \u2014 pas des secondes.<\/p>\n

\"Laboratory
Des scientifiques m\u00e8nent une exp\u00e9rience d'entra\u00eenement sur des poissons dans un grand bassin afin de tester leur m\u00e9moire spatiale.<\/figcaption><\/figure>\n

L'exp\u00e9rience de pression sur le levier<\/h3>\n

Une autre exp\u00e9rience consistait \u00e0 utiliser un levier qui ne distribuait de la nourriture qu'\u00e0 certains moments. Les poissons ont appris \u00e0 l'actionner uniquement \u00e0 l'heure du repas, d\u00e9montrant ainsi leur capacit\u00e9 \u00e0 associer le temps, l'action et la r\u00e9compense \u2013 un signe de fonctions cognitives avanc\u00e9es.<\/p>\n

Les poissons qui apprennent de leurs erreurs ont assur\u00e9ment une excellente m\u00e9moire.<\/h3>\n

Une \u00e9tude men\u00e9e en 2017 sur des guppys a r\u00e9v\u00e9l\u00e9 que ces poissons peuvent am\u00e9liorer leurs performances<\/em> dans des labyrinthes gr\u00e2ce \u00e0 un entra\u00eenement r\u00e9p\u00e9t\u00e9. Apr\u00e8s quatre jours, ils ont parcouru le labyrinthe beaucoup plus rapidement qu'au premier jour, ce qui t\u00e9moigne d'un apprentissage par la m\u00e9moire similaire \u00e0 celui des mammif\u00e8res.<\/p>\n

Comportements complexes\u00a0: utilisation d\u2019outils et tromperie<\/h3>\n

On a observ\u00e9 certaines esp\u00e8ces de poissons utiliser des outils pour se nourrir. Par exemple, on a observ\u00e9 des labres, notamment le labre-d\u00e9fense \u00e0 points orange. utiliser des pierres comme outils.<\/strong> Il s'agissait de jeter des pierres sur les oursins pour briser leurs coquilles. D'autres, comme Poisson voilier<\/a>Les poissons font preuve de strat\u00e9gies de protection en fixant leurs \u0153ufs aux feuilles des plantes, ce qui leur permet de les d\u00e9placer rapidement en cas d'attaque du nid. Ces comportements d\u00e9montrent que les poissons ne sont pas des cr\u00e9atures d\u00e9nu\u00e9es d'intelligence, mais des \u00eatres intelligents capables de planifier et de s'adapter.<\/p>\n

Le comptage et la reconnaissance des chiffres ne sont certainement pas des signes de faiblesse de la m\u00e9moire.<\/h3>\n

Des chercheurs ont pr\u00e9sent\u00e9 \u00e0 des poissons des cartes comportant un nombre variable de points. Sur plus de 1\u00a0200 tests, les poissons ont choisi la bonne carte \u00e0 chaque fois (91%). Cela d\u00e9montre leur capacit\u00e9 \u00e0 comparer des nombres et \u00e0 m\u00e9moriser des motifs\u00a0\u2014 des aptitudes que l\u2019on croyait autrefois r\u00e9serv\u00e9es aux animaux sup\u00e9rieurs.<\/p>\n

Les raies manta se souviennent-elles de leurs trajets ?<\/h3>\n

Les raies manta peuvent parcourir plus de 2\u00a0000 km \u00e0 travers l'oc\u00e9an, et ce n'est pas par hasard. Ces doux g\u00e9ants se souviennent ann\u00e9e apr\u00e8s ann\u00e9e de leurs routes migratoires, de leurs lieux de nourrissage et de leurs stations de nettoyage. Les scientifiques pensent que les raies manta\u2026 utiliser \u00e0 la fois la m\u00e9moire et les indices environnementaux<\/em> Pour se rep\u00e9rer. C'est comme s'ils portaient une carte invisible dans leur esprit, les guidant en toute s\u00e9curit\u00e9 \u00e0 travers le vaste monde bleu.<\/p>\n

M\u00e9moire dans les applications aquacoles<\/h3>\n

Des scientifiques ont appliqu\u00e9 la m\u00e9moire des poissons \u00e0 l'aquaculture durable. En entra\u00eenant les poissons \u00e0 r\u00e9agir aux sons \u00e9mis pour se nourrir, les \u00e9leveurs peuvent ensuite les rel\u00e2cher en mer et les rappeler lors de la r\u00e9colte gr\u00e2ce au m\u00eame signal sonore. Cette m\u00e9thode ing\u00e9nieuse prouve que les poissons ont une excellente m\u00e9moire\u00a0; en r\u00e9alit\u00e9, ils peuvent se souvenir et r\u00e9agir apr\u00e8s des semaines<\/strong> voire des mois. Cela permet \u00e9galement de r\u00e9duire les co\u00fbts d'alimentation et de soutenir une agriculture respectueuse de l'environnement, gr\u00e2ce \u00e0 la m\u00e9moire solide et fiable des poissons.<\/p>\n

Les poissons peuvent reconna\u00eetre les visages, donc pas de mauvaise m\u00e9moire !<\/h3>\n

Des \u00e9tudes ont montr\u00e9 que les poissons-archers peuvent se souvenir des visages humains et les reconna\u00eetre, m\u00eame apr\u00e8s en avoir vu des dizaines. Autre anecdote int\u00e9ressante\u00a0: une plongeuse a retir\u00e9 un hame\u00e7on de la gueule d\u2019un requin. Apr\u00e8s cela, le m\u00eame requin a commenc\u00e9 \u00e0 lui rendre visite r\u00e9guli\u00e8rement, et amenait m\u00eame d\u2019autres requins avec des hame\u00e7ons coinc\u00e9s dans la gueule, comme si\u2026 demander de l'aide<\/a>Cela montre que les poissons peuvent reconna\u00eetre les gens, se souvenir d'exp\u00e9riences positives et m\u00eame les communiquer \u00e0 d'autres.<\/p>\n

Le mythe de la faible m\u00e9moire des poissons est totalement faux.<\/h2>\n

La recherche scientifique prouve que les poissons peuvent se souvenir de choses pendant des semaines, voire des mois. Ils apprennent de leur exp\u00e9rience et font preuve d'une intelligence surprenante. Alors la prochaine fois que quelqu'un dira : \u00ab Il a une m\u00e9moire de poisson ! \u00bb, vous pourrez le corriger sans h\u00e9siter.
