Trout - He pono hana?

Ka hope makahiki i ike i kekahi lālā hoihoi i loko o koʻa. A hailona no ka poe liilii, pāʻoihana ana komo ma ka mahi ana i kekahi mau laha 'o ka iʻa i ka loko iʻa hoʻolimalimaʻia. Mawaena o ka waiwai? Ueo o Salemona e hiki ke i nā artificially, i waena o ka mea mua e ku ana trout. Keia ia, i mea dietary ai me ka maikaʻi ke kinoʻono, kekahi ua manaoia he environmentally launa huahana ia mea i loko o koi nui i waena o nā kānaka kūʻai mai. No ia mea, trout ua lilo hou, he pono ole, a loa e pono pāʻoihana.

Mea Maluna o ka trout mea paʻakikī no kekahi mau kumu, a conventionally ka mea, ua maheleia i mau ano: mea eleele a me anuenue. i ka hapanui i lawe mai i ka iʻa aina ? aneii o ke anuenue trout, i mea hiki ole wale i loko o ke anu holo Track, akā, i loko o ka mehana wai. No ka mea ulu o keia? Ueo mai i koi nui mau mea o ka aina. Ke wale ano no kona holomua Launch a me ka ulu - maʻemaʻe, a hoʻopihaʻia me ka o oxygen ka wai, me ka lawa mōakaaka a me ka aa pono ana.

Trout i kona kiʻiona hiʻona: ka incubation o ka hua a me nā 'ōpio ulu wale ia lŘlŘ ma ka ikaika ana wela ka wai. Na kaʻoi loa wela huahelu ka 15 i ka 18 degere. Ma keia hihia, ke alo o ka maoli ka ai, trout ulu mau: fingerlings mai i 30 nā huna o ke kaupaonaʻana, yearling kanaka i 100-120 nā huna, a me nā makahiki Nalani Olds ke kaupaona oi ma mua o 200 nā huna.

Me ka fertility 'ano maikai o ka wahine (mai ka 800 a hiki i 3000 hua) trout mea hiki wale ma ka mea o ka mea, hoʻoikaika ihola fertilization o nā hua paha, e like me kaʻimi hoʻopunipuni loko trout ia mea,ʻaʻole he Hale Pule Isalama. Ke kaʻina hana o ka insemination Ua like penei: ma nā kiʻie oʻo wahine i loko o ka ipu nui decanted caviar. A laila, hele mai no ka huli ana o "milking" o kāne nā hoʻohua. Ke kūpono kaʻina milt'anetelope, ua pono i hui pūʻia me ka maloo a me kalaka nui-maloo hana. Inā hua i hui pūʻia me ka sperm mua nāu kekahi i loko o ka wai, i kēia kalaka nui-maloo iaoia o fertilization. Ma ke kaʻina maloo insemination huahana mea mua i hui pūʻia, a laila, wale keia nuipa a ua pākuʻi i ka wai, a laila, ma lalo i ka manaʻo pīhoihoi.

Artificially fertilized hua, hoouna mai i ka hatchery. Ma waho bipi mālama malaila, a hoʻomoe larvae. I ka ulu i ka larvae i fry, ka mea, e like nā hoʻohua i spawning, e transplanted. No hoi, ua hoike i ka huakūʻai trout. A hou hana o ka ulu ana e kaukaʻi ma ka kohoʻano hana: ma ka poʻina nalu a me nā hīnaʻi manu.

A me ka mea maikaʻi loa hopena ua loaʻa ma ke ano mua, mahope mai o kēiaʻano mālama nui mahi (i ka hua mea oi aku mamua o 75 kg no 1 cubic mika). Eia naʻe, ia mea paʻakikī loa ka hana-mālama nui. Loli ana o ka wai no ka haawiia mai kaʻina ua hana kela 10-15 minuke, a me kona pele i kela mea ma kahi o 50 nā lika no minuke, no 1 tausani poo trout. I ka pa apŘ o ke huakūʻai trout kanu mea e pili ana i 300-350 kope no cubic mika, a me fry 1 gram - mai ka 2000 a hiki i 5000 kanaka no mika polū.

Ka lua o ka hana, trout i loko o nā hīnaʻi manu maʻalahi. Kanaka i hoonoho iho ma ka nylon a ma i ko lakou ulu ana metala hei. No laila, ka mea ana nuʻa huakūʻai trout pono i oi aku mamua o 250 kope no cubic mika o ka wai. Palua o ka manawa i loko o nā hīnaʻi manu i ka mea o nā 'ōpio.

Kēia hana kūikawā Pono noonoo ana i ke ana o ka hui hoʻomaʻemaʻe kūmau o ka wai, e like me ka pilikia o ka make o ka iʻa hapahā like me ka hopena o kona mahuahua haumia ea.

Ke kumuhana Ke i nāʻanoʻenehana a me ka hui hoʻomaʻemaʻe mau hae trout i pono uku hoʻi hana. Kona productivity (. Per 1 cubic mika) wā ulu i loko o vivo fry loko hiki 25-35, i loko o nā hīnaʻi manu - 30-35, a me 50-75 ma loko kilogram.
