Gukaraba amafi aba mu nyanja ikonje ya Atlantike na pasifika. Nibicuruzwa byingirakamaro bikunzwe numuguzi bitewe no gufata neza kwa poroteyine nyuma yo kuvura ubushyuhe. Moja akungahaye kubintu byingirakamaro bigira ibicuruzwa byingenzi mu gukumira no kuvura indwara za sisitemu yimitima. Ariko, vuba aha, Moisa ntiyongeye guhura, kandi igiciro cyacyo cyakuze cyane.
Ibisobanuro by'amafi
Moisa ni amafi ya pelagique afite umunzani muto kandi amenyo mato. Uburebure bw'umubiri bugera ku gice 25, gake cyane kurenga 50 g. Kuzunguruka kw'amafi bifite igicucu cya elayo cyijimye, impande n'inda ifeza. Ikaramu ya dorsal na munda bigaragara inyuma yumubiri. Amafi afite dimorphism igaragara: igitsina gore ni gito kuruta igitsina gabo, hiyongereyeho, nyuma ni umunzani mwinshi kandi ukomeye kumpande.
Amafi atuye gusa mu nyanja, gake cyane (mugihe cyo kubyara) kwinjira mu kanwa k'inzuzi. Abazana amavuta ahanini na plankton na crustaceans nto. Abanywanyi bakomeye bo gukaraba mumurongo wibiryo barushijeho kuba barumuna bawe badatunganye.
Ubusanzwe abantu nuburyo budasanzwe bwo gutanga. Amafi yabumbaga caviar hafi ku nkombe. Igihe cya shelegi giterwa nakarere, ariko burigihe kibaho mugihe gishyushye. Mbere yo kwinjira mu mbaraga, amafi agiye mumikumbi minini ikurura ibisubizo bya alt, kashe ndetse na baleine.
Buri mugore, uherekejwe n'abagabo benshi, yajugunywe mu rupfunda mu gihimbano, aho na caviar mosk. Nyuma yibyo, igitsina gore kizunguruka mu nyanja, kandi abagabo hafi ya bose baguma ku nkombe. Ugereranije, igitsina gore ni uguhura 2-3, abagabo bapfa nyuma yambere.
Amafi arateganijwe cyane. Buri mugore ashobora kubona amashusho agera ku gishushanyo 60. Urakoze ku bunini bwabo, kandi ikintu kimwe nuko amezi 1.5 ya mbere ya Fry atuye mu mucanga wo ku nkombe, imyororokere nziza y'abaturage bemejwe.
Imyaka yimyororokere yigitsina gore ni imyaka 2-3, abagabo imyaka 3-4. Ifi ntarengwa irashobora kubaho mumyaka 10.
Imiterere yabaturage
Moisa nigice cyingenzi cya Arctoysy Ecosystem ya Arctic, bityo gufata bitagenzuwe birashobora guhinduka ibintu bidasubirwaho mumarimbi yinyamaswa yinyamaswa. Kubera ko ari ibiryo byinyamabere nini yo mu nyanja, inyoni n'amafi, kugabanya abaturage bayo bigira ingaruka ku buryo bw'abaturage b'amahanga. Bahatirwa kwimuka bashaka ibiryo, cyangwa uhindukire ku rindi mbarwa.
Nubwo uburobyi bwo gukaraba ari bunini, kandi uko byafashwe mu mpera z'ikinyejana cya 20 bwageze kuri toni 4 ku mwaka, ku gaciro kayo igera ku bipimo bitwiteho cyane. Ku turere twinshi two mu karere muri iki gihe, habaho guhagarika inkoni z'ubucuruzi cyo gukaraba.
Kubwibyo, igiciro cyamafi kumarana 400 kuri kilo ntigomba gutungurwa. Kubuzwa gufata neza byagabanije ibyifuzo byisoko kandi igiciro cyakuze. Kandi kubera ko umusaruro mwinshi wo gukaraba urabujijwe, birashoboka rero ko iki gicuruzwa kiriho mububiko, kubishyira mu gabasi, bibeshya.
