Te Whakahaere Kounga Wai i roto i ngā Pāmu Ika
Pendahuluan
Kua noho te mahi pāmu ika hei rāngai nui mō te whakatutuki i ngā hiahia kai o te ao. Tērā pea ka taea e tēnei mahi te whakarato i tētahi puna pūmua hauora, whai kiko hoki mō te tini o te tangata. Heoi, ko te angitu o te mahi pāmu ika e whakawhirinaki nui ana ki te whakahaere kounga wai. Ehara i te mea ko te wai anake te huarahi mō ngā ika ki te ora, engari he pānga anō hoki ki tō rātou oranga, ki tō rātou tipu, me tō rātou hauora. Nō reira, he mea nui te whakahaere kounga wai pai mō ngā mahi pāmu ika. Ka matapakihia e tēnei tuhinga ngā āhuatanga matua o te whakahaere kounga wai e tautoko ana i te angitu o te mahi pāmu ika.
Ngā Take e Whakatau ana i te Kounga o te Wai
Hei whakarite kia ora, kia tino pai hoki te tipu o ngā ika i roto i te pāmu, me aroturuki me te whakahaere i ētahi tawhā kounga wai. Kei roto i ēnei tawhā ko te pāmahana, te hāora rewa, te pH, te haukini, te nitrite, te nitrate, me ngā poke koiora me ngā poke matū.
1. Te pāmahana
He nui te pānga o te pāmahana wai ki te pākia o te ika. He awhe pāmahana pai tō ia momo ika hei tautoko i te tipu pai. Hei tauira, he rerekē te awhe pāmahana o ngā ika wai māori pērā i te ika kāpeti me te tilapia i ngā ika wai tote pērā i te tāmure me te karāhe. Ka taea e ngā pāmahana i waho o te awhe pai te whakararuraru i te pākia o te ika, ka pā ki tō rātou tipu me te hauora.
2. Hāora Whakarewa
Ko te hāora rewa (DO) tētahi o ngā tawhā tino nui i roto i te mahi pāmu ika. Ka taea e ngā taumata hāora iti te whakararuraru, te mate rānei i ngā ika. Ka pāngia te hāora rewa e te pāmahana, te tote, me te taumata o ngā mea rauropi i roto i te wai. He maha ngā wā ka whakamahia te hauhautanga ā-ringa, te whakamahi rānei i ngā hauhautanga, hei whakanui ake i ngā taumata hāora rewa i roto i ngā roto mahi pāmu ika.
3. pH
He nui hoki te pānga o te waikawa, te kawakore rānei (pH) o te wai ki ngā āhuatanga ā-tinana me ngā āhuatanga matū o te wai. He rerekē te awhe pH pai o ngā ika i waenga i ngā momo. I te nuinga o te wā, he pai te pH i waenga i te 6,5 me te 9 mō te nuinga o ngā ika ahuwhenua. Ka taea e te pH waikawa rawa, kawakore rawa rānei te whakararuraru i ngā mahi ā-tinana o ngā ika me ngā moroiti whai hua i roto i te pūnaha ahuwhenua.
4. Haukini, Nitrite, me te Nitrate
Ka puta te haukini, te nitrite, me te nitrate mai i ngā toenga kai me ngā paru ika. Mēnā he nui te rahinga, he paitini ēnei matū. He tino kino te haukini i roto i tōna āhua ionized (NH3) ki ngā ika, ā, ka taea e ia te whakakino i ngā kiko o te wahapū. Mā te tukanga nitrification, e mahia ana e ngā huakita nitrifying, ka huri te haukini ki te nitrite (NO2-) kātahi ki te nitrate (NO3-). Ahakoa he iti ake te paitini o te nitrate i te haukini me te nitrite, me whakahaere tonu tōna aroaro i ngā kukū tiketike.
5. Ngā Parahanga Koiora me ngā Parahanga Matū
Ka taea e ngā huakita, ngā huaketo, ngā harore, me ngā pirinoa te whakararu i ngā ika i ngā mate. Hei tāpiri, ka taea hoki e ngā parahanga matū pērā i ngā konganuku taumaha, ngā patupatu pepeke, me ngā matū ahumahi te whakararu i te hauora o ngā ika. Nō reira, he mea nui te aroturuki me te whakahaere i ngā parahanga koiora me ngā matū hei pupuri i te kounga pai o te wai.
Ngā Tikanga me ngā Utauta mō te Whakahaere Kounga Wai
He maha ngā tikanga me ngā taputapu hei āwhina i te whakahaere kounga wai i roto i ngā pāmu ika, anei ētahi e whakamahia whānuitia ana:
1. Te whakapūngao
Ko te mahi a ngā pūwero hau hei whakapai ake i te hāora rewa i roto i te wai, kia pai ai te manawa o ngā ika. Ko ngā momo pūwero hau e whakamahia whānuitia ana ko ngā pūwero hau hoe, ngā pūwero hau whakarara, me ngā pūwero hau venturi. Ka āwhina hoki te pūwero hau ki te wawahi i te thermocline me te whakatairanga i te nekehanga o te wai, ka whakaiti i te tūponotanga o te wehewehenga hāora.
2. Pūnaha Tātari Koiora
Mā te whakamahinga o ngā huakita whakapūkara i roto i ngā tātari koiora ka āwhina i te wawahi i ngā matū haukini ki te nitrite, kātahi ki te nitrate, he mea haumaru ake mō ngā ika. He tino whai hua tēnei pūnaha ki te pupuri i te kounga wai taurite, inā koa i roto i te whakaputa ika nui.
3. Kete Aroturuki me te Whakamātautau
Ko ngā taputapu ine kounga wai pērā i ngā inemahana, ngā oximeter, ngā mita pH, me ngā kete whakamātautau mō te haukini, te nitrite, me te nitrate he taputapu paerewa mā ngā kaipāmu ika. Mā ēnei taputapu ka taea te ine tere me te tika i ngā tawhā kounga wai nui.
4. Tātari
Ka taea e te tātari ā-tinana te tango i ngā matūriki totoka, engari ka taea e te tātari matū te āwhina ki te tango i ngā matū paitini me ngā poke rauropi. He mahi nui tā ngā tātari ā-ringa, ā-koiora, me ā-matū ki te pupuri i te kounga o te wai.
5. Te Whakahaere Rauemi Wai
Me kore he parahanga o ngā puna wai, ā, me kounga pai hoki. He mahi pai te whakamahi i ngā puna wai kua whakamātauria te kounga. Mā te whakahaere tika i ngā puna wai ka ārai i te parahanga o te wai me ngā raruraru kounga pea.
Whakahaere Whāngai
Mā te whāngai pai me te whakamahinga tika ka whakaiti i te parahanga wai mai i ngā toenga kai. Mā te whāngai nui ka piki ake te nui o te haukini, ā, ka nui ake te haukini. Mā te whakamahi i ngā kai he pai te huringa, me te nui hoki i te wā tika, ka whakaiti i ngā pānga kino ki te kounga o te wai.
Te Ārai me te Whakahaere i ngā Mate
Mā te whakamahi i ngā probiotics, i ngā kano ārai mate rānei, ka āwhina i te whakaiti i te horapa o ngā mate i roto i ngā roto ahumoana. Me tino tupato te whakamahi i ngā matū, i ngā rongoā rānei, kia kore ai e poke te wai, kia kore ai hoki e tūpono ki te hauora o ngā ika.
Whakamutunga
Ko te whakahaere pai i te kounga o te wai te mea nui ki te angitu o te mahi pāmu ika. Mā te aroturuki tata me te whakamahi i ngā hangarau tika ka taea te waihanga i tētahi taiao e pai ana mō te tipu o ngā ika. Ko te mārama me te whakahaere i ngā tawhā kounga wai pēnei i te pāmahana, te hāora rewa, te pH, te haukini, te nitrite, me te nitrate, tae atu ki te whakahaere i ngā poke koiora me ngā matū, he mea nui. Mā te whakahaere kounga wai whai hua, ka nui ake te hua, te whai hua, me te pumau o te mahi pāmu ika.
