He whānui te horapa o te Macrobrachium rosenbergii.kōura wai māorihe nui te uara kai, ā, he nui hoki te hiahia o te mākete.

Ko ngā tikanga matua o te whakaputa uriKōura Rochekoia ēnei:
1. Te whakatipu ika kotahi: arā, ko te whakatipu kōura Roche anake i roto i te wai kotahi, kaua i roto i ētahi atu kararehe wai. Ko ngā painga o tēnei tauira ahuwhenua ko te whakahaere ngāwari me te nui o ngā hua, engari ko ngā ngoikoretanga ko te kounga wai teitei, te ngāwari o te pā mai o ngā mate me te kai tahi.
2. Te whakatipu ika whakaranu: e pā ana ki te whakatipu kōura Roche me ētahi atu kararehe wai pērā i te ika, te ngata, te kūtai, me ētahi atu i roto i te wai kotahi. Ko te painga o tēnei tauira whakatipu ika ko te whakamahi i te wāhi maha-paparanga o te wai, te whakapai ake i te hua o te wai, te whakanui ake i ngā pūtake moni, me te whakaiti i te whakataetae me te kaipahua i waenga i ngā kōura Roche, ā, mā reira ka whakaiti i te putanga mai o ngā mate. Engari ko te ngoikoretanga he uaua te whakahaere, ā, me aro nui ki te whiriwhiri me te ōwehenga o ngā momo whakatipuranga kia kore ai e awehia ngātahitia me te hopu kai.

3. Te whakatipu ika hurihanga hua: e pā ana ki te whakatipu tauwhitiwhiti o Procambarus clarkii me ētahi atu kararehe wai i roto i te wai kotahi i runga i tētahi raupapa wā, pērā i te whakatipu kōura i ngā mara raihi me te whakatipu ika i ngā pāmu raihi. Ko te painga o tēnei tauira whakatipu ika ko te whakamahi katoa i ngā huringa o te wā i roto i ngā wai, te whakatutuki i ngā painga rua mō ngā hua wai me ngā hua whenua, me te whakapai ake i te taiao taiao o ngā wai me te whakaiti i te putanga mai o ngā mate. Engari ko te ngoikoretanga ko te aro nui ki te whakaritenga o te huringa whakatipuranga kia kore ai e pokanoa tetahi ki tetahi me te awe i waenga i ngā hua wai me ngā hua whenua.

Ngā Painga me ngā Wero o te Hangarau Whakatipu Kōura Roche:

1. Ko ngā painga o te hangarau whakatipu pāpaka Roche ko ēnei e whai ake nei:
He hua wai nui te uara o te pāpaka Roche, he nui te uara kai me te nui o te tono mākete, ā, ka hua mai he hua ōhanga nui.
2. He kararehe kai-katoa te pāpaka Roche, he whānui hoki āna momo kai, ka taea e ia te whakamahi i ngā kai māori me ngā mōunu iti te utu i roto i ngā wai hei whakaiti i ngā utu whakatipu.
3. He kararehe tino urutau te parāoa Roche, he whānuitia ngā pāmahana me ngā tote o te wai, ā, ka taea te whakatipu i roto i ngā wai rerekē, ka nui ake te ngāwari o te mahi ahuwhenua ika.
4. He kararehe tere tipu te pāpaka Roche, he poto te huringa tipu me te nui o te hua, ka taea e tēnei te whakapoto i te huringa whakaputa uri me te whakapai ake i te whai huatanga o te whakaputa uri.
5. He kararehe pai te pāpaka Roche mō te mahi ahuwhenua whakauru me te mahi ahuwhenua hurihuri hua, ka taea te tāpiri atu ki ētahi atu kararehe me ngā hua wai, te whakapai ake i te hua o te wai, me te whakatutuki i te whanaketanga kanorau o te mahi ahuwhenua me te mahi ika.
Ko ngā wero matua o te hangarau whakatipu pāpaka a Roche ko ēnei e whai ake nei:
1. He kararehe kounga wai teitei te pāpaka Roche, ā, he nui te pānga o te kounga wai ki tōna tipu me tōna whanaketanga. Me whakapakari te aroturuki me te whakahaere i te kounga wai hei ārai i te parahanga me te hekenga o te wai.
2. He kararehe ngāwari te pāngia e ngā mate te pāpaka Roche, he iti te ārai mate, ā, he ngāwari hoki ki ngā mate pēnei i te huakita, te huaketo, te harore, me ngā pirinoa. Nō reira, me whakapakari te aukati me te whakahaere i ngā mate hei whakaiti i te mate me te ngaronga o te pāpaka Roche.
3. He kararehe ngāwari te pāpaka Roche ki te kai kino tetahi ki tetahi, he rerekētanga nui te ōwehenga ira tangata me te rahi o te tinana, ka arahi pea tēnei ki te whakataetae me te whakaeke i waenga i ngā pāpaka tāne. Nō reira, me whakapakari te whakahaere i te ōwehenga ira tangata me te ōritetanga o te rahi o te tinana hei whakaiti i ngā pakanga me ngā whara i waenga i ngā pāpaka Roche.
4. He kararehe e pāngia ana e ngā piki me ngā heke o te mākete te pāpaka Roche, ā, ka rerekē te utu me te tono i runga i ngā wā me ngā rohe. He mea tika kia whakapakarihia te rangahau me te tātari mākete, kia hangaia he tauine me ngā whāinga whakatipu tika, kia kore ai e taurite te tuku me te tono me te hekenga o te utu.

Ko ngā painga nui o te DMPT (Dimethyl - β - Propionate Thiophene) e whai ake nei i roto i te mahi ahuwhenua ika, inā koa i roto i te mahi pāmu kōura:

1. Whakapai ake i te whai huatanga o te whāngai
Ka whakanuia e te DMPT te auau me te tere o te whāngai, ka whakapoto i te wā whāngai, ā, ka whakaiti i te para kai mā te whakaoho i ngā kaiwhakawhiwhi hongi me te manawa o te pāpaka. Kua whakaatuhia e ngā rangahau mā te tāpiri i te DMPT ki te kai ka taea te whakanui ake i te tere whakamahinga mā te 25% -30% me te whakaiti i te mōrearea o te parahanga wai.
Whakatairanga i te tipu me te whakaheke i te huruhuru.
2. Ka taea e te DMPT te whakatere i te huringa whakamomona o te kōura, me te whakapoto i te huringa tipu. I taua wā, ka taea e tōna hanganga kei roto he whanariki te whakatairanga i te pākia o te waikawa amino, te whakapai ake i te whakamahinga o ngā waikawa amino, me te whakarei ake i te whai huatanga o te tipu.
3. Whakapai ake i te kounga mīti me te uara ōhanga.

4. Ka taea e te DMPT te whakapai ake i te reka o te mīti o te kōura, ka hoatu he reka hou, he reka hoki ki te kōura wai māori, he rite ki te reka o te kōura moana, ā, ka whakarei ake i te whakataetae mākete.

5. Te Haumaru me te Tiaki Taiao.

6. Kāore he paitini o te kōura DMPT, he iti noa ngā toenga, ā, e tutuki ana i ngā whakaritenga o te mahi ahuwhenua matomato.
