Harada Alaotra (Af Malagasy: farihin' Alaotra, [faˈrihin ˈaloʈʂə̥]; Af Faransiis: Lac Alaotra) waa harada ugu weyn Madagascar, waxay ku taal Gobolka Alaotra-Mangoro iyo dhulka sare ee bartamaha waqooyi ee jasiiradda. Weelkeedu wuxuu ka kooban yahay harooyin biyo macaan oo joog hoose ah iyo maryafeexyo ay ku hareeraysan yihiin aagag leh dhir cufan.[3] Waxay samaysaa bartamaha gobolka ugu muhiimsan jasiiradda ee bariiska laga soo saaro. Waa deegaan qani ku ah duurjoogta, oo ay ku jiraan noocyo dhif ah oo halis ugu jira dabar-go', iyo sidoo kale goob muhiim ah oo kalluumeysi. Harada Alaotra iyo dhulkeeda qoyan ee ku xeeran waxay daboolaan 7,223 square kilometres (2,789 sq mi), waxaana ku jira deegaano kala duwan, oo ay ku jiraan biyo furan, caws-biyood, maryafeexyo, iyo beero bariis ah. Harada lafteedu waxay daboolaysaa 900 km2 (350 sq mi). Harada Alaotra waxaa loo aqoonsaday dhul qoyan oo muhiimad caalami ah leh iyadoo hoos timaada heshiiska caalamiga ah ee Ramsar Convention bishii Febraayo 2, 2003.
Kalluunka tilapia ee baalka dheer (Oreochromis macrochir) waxaa laga soo mastaafuriyay dhulka weyn lagana soo dhex saaray Harada Alaotra sannadkii 1954 wuxuuna u tarmay si degdeg ah. Sannadkii 1957, wuxuu bixiyay 46% qabsashada kalluunka, laga yaabee sababtoo ah wuxuu u guuray meel deegaan oo bannaan isagoo ah nooc dhirtu qubata ah.[4]
Dhulka fidsan ee bacrin ah ee ku xeeran Harada Alaotra waa gobolka ugu muhiimsan Madagascar ee bariiska laga soo saaro. Buuraha ku xeeran harada waxay ahaan jireen kuwo kaymo ah laakiin badankooda waxaa loo xaalufiyay dhul beereed tobannaankii sano ee la soo dhaafay. Nabaad-guurka daran ee ka dhacay jiirada buuraha ee nugul wuxuu sababay ururka dhoobada ee weyn ee harada, taas oo si degdeg ah u sii dabar-gaysa; haradu hadda moolkeedu waa uun 60 cm (24 in) inta lagu jiro xilliga qallalan. Cadaadiska lagu abuurayo beero bariis oo horleh ayaa sidoo kale ku riixay dadka deegaanka inay gubaan caws-biyoodka ku xeeran harada. Caws-biyoodkan ayaa bixiya deegaanka keliya ee uu ku nool yahay lemur-ka u gaarka ah ee Lemur-ka deggan ee Alaotra (Hapalemur griseus alaotrensis). Lemur-ka deggan ee Alaotra wuxuu hadda ku xaddidan yahay oo uun ku haray 220 km2 (85 sq mi) oo caws-biyood ah, sannadaha hantida ahna, tiradoodu waxay hoos u dhacday si degdeg ah oo gaaraysa 60%, iyadoo ka soo degtay qiyaastii 7,500 shakhsi sannadkii 1994 lana ogaaday 3,000 sannadkii 2001, inta badanna waxaa sababay lumitaanka deegaanka, iyo sidoo kale ugaarsiga dadka tuulooyinka deegaanka.
Haradu waa goobtii nooca ee laga helay balanbaalistada Artitropa alaotrana iyo deegaan muhiim ah laakiin aad u sii khatar galaya oo ay leeyihiin shimbiraha biyaha, oo ay ku jirto shimbirta halista ugu jirta dabar-go'a ee gandada Meller (Anas melleri). Laba nooc oo shimbiraha biyaha ah ayaa u gaar ahaa waqooyiga Madagascar, kuwaas oo kala ah banyeerka Madagascar (Aythya innotata) iyo banyeerka Alaotra (Tachybaptus rufolavatus). Banyeerka Madagascar hadda aad ayuu u halis ugu jiraa dabar-go' walina lagama helo harada, inkastoo tiro aad u yar ay ka jiraan meelo kale. Banyeerka Alaotra waxaa lagu dhawaaqay inuu dabar-go'ay sannadkii 2010. Aagga harada ayaa laga yaabaa inuu ahaa deegaankiisa keliya.[5]
Webiga Ambato wuxuu harada siiyaa biyo, sidoo kale waa uu ka bixiyaa. Ka dib 381 km, webigu wuxuu ku shubmaa Badweynta Hindiya.
Dhulka la ilaaliyo ee isku-dheelitiran ee Harada Alaotra waxaa maamula ururka Durrell Wildlife Conservation Trust.[6]
