He aha te wāhanga tika o te monocalcium phosphate i ngā kai moana?

I tē tau kua pahure, i whai wāhi ahakoa ki tēnei pātaka kōura i Tōtahi Hauāwhi, i tēnei wā i rere te whakamāmā o ngā kōura me te iti o ngā whāinga oranga o ngā kōura Litopenaeus vannamei i ngā wāhi kōura. I tātou kōrero mai ki ahakoa i tātou whakamātua i ngā whakamātua phosphate i ngā wāhi rere, ā, kāore i tātou kite he hua pai. I tātou tohutohu i tā mātou monocalcium phosphate mai i tā mātou kamupani, ā, i whakamārama i tēnei whakamātautau e toru ngā rōpū, me ngā whakamātua rere: 0.8% 1.2% me 1.5% o te taumaha o te kai moana katoa. I whakamāhinga ngā kai i tā mātou whakamātua monocalcium phosphate i te wā o ngā rā e 60, ā, i tātou tuhi ngā kōrero katoa. Ko te rōpū i te whakamātua monocalcium phosphate 1.2% i whakamātau i ngā hua mīharo: i piki ake te tau o ngā kōura whakamāmā o ngā kōura i te 35%, ā, i piki ake te whāinga oranga mai i te 62% ki te 88%. Ko ngā kōura i tēnei rōpū hoki i whakamātau i te kiko mātātū, i te whananga tere ake, ā, i te piki ake o te taumaha i te 40% i te whāinga o ngā rōpū kē. I whakaahu mai tēnei whakamātautau i tēnei: ko te monocalcium phosphate e mahi ana i ngā hua mīharo, engari ko te whakamātua tika anō te take, ā, ko te pūkenga mātātū o tā mātou hua e whakamārama ana i te whakamātua tika, ā, e whakamārama ana i te whakamātua tika hei wāhi mātātū, hei wāhi whakamārama mō ngā whakamātautau moana.

Ko te monokalasiamu phosphate te whakamātautau pū, te whakamātautau tino mō ngā whakamātautau phosphorus mō ngā kai moana, ā, ko tōna whakamātautau pai rawa atu e hono ana ki te hiahia phosphorus o ngā kararehe moana. Ko ngā kararehe moana pērā i ngā ika me ngā koura e hiahia ana i te phosphorus mō te whananga o ō rātou tuarā, te hanganga o ō rātou kōpae, te whakamātautau hiko, me te wehenga o ngā seli, he nui ake i ngā kararehe whenua, nā te mea he māmā te ngaro o te phosphorus i te wai i te whakamātautau. Ko tā mātou monokalasiamu phosphate he iti te whakamātautau o te phosphorus e wātea ana, ā, arā, ko te nuinga o te phosphorus i roto i tēnei e whakamātautau ai e ngā kararehe moana, kāore he ngaro i te wai. He rerekē ngā hiahia whakamātautau mō ngā kararehe moana rerekē; ko ngā kōura me ngā pāpaka e hiahia ana i ngā whakamātautau monokalasiamu phosphate nui ake, i te 10 ki te 15 huringa mō ō rātou whakamātautau maha, i te rā anō, ko ngā ika wai mā, pērā i te kāpā, e hiahia ana i te 0.6 ki te 1.0 huringa anō. Ko ngā kararehe moana iti ake hoki e hiahia ana i te monokalasiamu phosphate nui ake i ngā pakeke, nā te mea kei te wā whakamātautau o rātou whananga me ō rātou whakamātautau. Ko te whakamātautau māmā o tā mātou monokalasiamu phosphate e whakamātautau ai i te kai kia rite tonu, kia taea ai te tohe i te whakamātautau o te phosphorus e hiahia ana ngā kararehe moana i ia kai.

A Dr James Reed, he kaiwhakamātautau mātua i ngā huinga kai moana, i tāna whakamātautau i ngā tau e 20 i tēnei wā i ngā whakamātautau i ngā kai moana, i tāna whakamārama tonu i te matua o te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i te whakamātautau i......

Ko ngā whakamāhua o tā mātou rōpū i te monocalcium phosphate he āhuatanga motuhake i whakamāhinga ai te whakamātautau i te wāhi o te kai mo ngā kaiwhakamāuiui, ā, ko ēnei āhuatanga ngā mea e wehe ana i ngā hua phosphate tāwāhi i te pānui. Tuatahi, ko te monocalcium phosphate o tā mātou he rite tonu te rahi o ngā pārāoa, nā reira e whai ana i te whakamātautau katoa ki ngā momo kai mo ngā kaiwhakamāuiui—ahakoa he kai pārāoa, he kai pārāoa rākau, he kai pārāoa whakamāuiui—kāore he whakamāuiui, kāore hoki he whakawhitinga kore. Ko tēnei whakamātautau e whakapāmama ana i te whakamātautau o te monocalcium phosphate i te whakamātautau kia tāwhai ai ngā kaiwhakamāuiui katoa. Tuarua, ko tā mātou hua he tāwhai tonu i ngā nutrihanga; kia kaha tonu te whakamātautau i ngā pārāoa o te monocalcium phosphate, ā, kia mau tonu te rahi o te phosphorus e wātea ana i tēnei rārangi, kia kāore ai ngā kaiwhakamātautau kai e whakamātautau i te whakamātautau i te rārangi o te hua i te rere o te kounga. Tuatoru, ko te monocalcium phosphate o tā mātou he tāwhai tonu i te wai; kāore he whakamātautau tōtika i te wai i muri i te whakaputanga o te kai ki ngā puna, ki ngā wāhi rānei, nā reira e whakamāhinga ana i te ngaro o te phosphorus, ā, e whakapāmama ana i te whakamātautau o te phosphorus e ngā kaiwhakamāuiui i mua i te whakawhitinga o te kai. Ko ēnei āhuatanga ngā take e whakamāhinga ana i te monocalcium phosphate o tā mātou hei whakamātautau tuatahi mō ngā whare kai, ngā pākai kaiwhakamāuiui hoki e whai ana i te whakamātautau tāwhai, i te whakamātautau tāwhai o te whakamātautau.

I runga i ngā tau o te whakamātautau o tā mātou kamupene i te oranga o ngā kai moana me ngā whakamātautau maha i te pūnaha, kua whakamārama mātou i ngā aratohu whakamātautau mō te whakamātautau i te monocalcium phosphate mō ngā karuhi kai moana rongonui hei āwhina i ngā kaihāpai me ngā kaiwhakamahi kai kia whakamāhi i tā mātou hua kia tika. Mō ngā kai moana kākāriki, ko Litopenaeus vannamei me Penaeus monodon e hiahiatia ana he 12 ki te 15 ōrau o te monocalcium phosphate i te wā o ngā kai moana iti, ā, he 10 ki te 12 ōrau i te wā o ngā kai moana matua; ā, ko ngā pāpā kai moana e hiahiatia ana he 13 ki te 16 ōrau i te wā o te whakamutunga, ā, he 9 ki te 11 ōrau i te wā kāore he whakamutunga. Mō ngā ika, ko ngā ika wai māwai pērā i te grass carp me te crucian carp e hiahiatia ana he 06 ki te 10 ōrau, ā, ko ngā ika tai pērā i te sea bass me te grouper e hiahiatia ana he 09 ki te 13 ōrau, ā, ko ngā ika iti e whakamāhi ana i te mutunga o te roa. I te wā e whakauru ana i te monocalcium phosphate ki te kai, he pai ake te whakauru i mua ki tēnei iti o ngā kai iti, kātahi ka whakarahi i te whakauru ki te katoa hei whakarite i te whakawhānuitanga. I tēnei hoki, he tino hiranga te whakamāhi i te monocalcium phosphate i runga i te taumata o te whānanga, mēnā he nui te phosphorus i te wai, ka whakamāmā i te whakamāhi, ā, mēnā he iti te tipanga o ngā kai moana, he rerekē te whakamutunga, ka whakakaha i te whakamāhi i raro i te ārahitanga o te mātua. Ko tā mātou rōpū mātua e wānanga ana i te 24 haora i ia rā hei whakarato i ngā whakamāhi monocalcium phosphate ā-wāhi i runga i tōu karuhi kai moana, i tōu wā whānanga, i ngā āhuatanga o te wai hei whakamāngai i ngā painga o te whānanga.
