II. Izalathisi zokuJonga uMgangatho waManzi oBalulekileyo kwiNdawo yokuFuya iiNtlanzi

(1) Iiparameters ezibonakalayo

1. Ubushushu

Eyona nto iphambili ebangela izinga le-metabolism, indlela yokutya, umsebenzi we-enzyme, kunye nexesha lokukhula. Uluhlu olufanelekileyo luyahluka ngokweentlobo: 20–30 °C kwininzi yeentlanzi zaselwandle; 12–18 °C kwi-turbot (I-Scophthalmus maximuskunye >22 °C kwi-penaeid shrimp (umz.,ILitopenaeus vannamei). IMPG-6099PLUSIjonga ubushushu obuphakathi kwe-0–60 °C ngokuchaneka kwe-±0.5 °C kunye nesisombululo se-0.1 °C, okuvumela ulawulo oluchanekileyo lwerejimeni yobushushu.

2. Utyuwa

Ilawula imfuno ye-osmoregulatory kwaye inefuthe kwibhalansi ye-ion, umsebenzi wegill, kunye nokusinda kwe-larval. Ukulima emanzini olwandle okuqhelekileyo kusebenza kwi-30-35 ppt; nangona kunjalo, iintlobo ze-euryhaline (umz., i-tilapia) zinyamezela uluhlu olubanzi (0-40 ppt), ngelixa iintlobo ze-stenohaline ezinzulu zolwandle zifuna uzinzo olukhethekileyo lwetyuwa. Ukuqonda ityuwa ngexesha langempela kuvumela ukulungiswa kwangaphambili ukuthintela uxinzelelo lwe-osmotic.

(2) Iiparameter zeKhemikhali

1. i-pH

Ibonakalisa uxinano lwee-ion ze-hydrogen kwaye ichaphazela kakhulu i-enzyme kinetics, i-gill permeability, ubuthi be-ammonia (NH₃ vs. NH₄⁺), kunye nokusebenza kakuhle kwe-nitrification. Uluhlu olucetyiswayo yi-6.5–8.5 kwiinkqubo zamanzi acocekileyo kunye ne-7.8–8.5 kwiinkqubo zaselwandle, kunye nokuguquguquka kwemini okungcono kakhulu yi-0.5 units. I-MPG-6099PLUS ilinganisa i-pH ukusuka kwi-0–14 ngokuchaneka kwe-±0.10 pH kunye nesisombululo se-0.01 pH, exhasa ukufunyanwa kwangoko kwe-acidification okanye iindlela ze-alkaliization.

2. Ioksijini enyibilikisiweyo (DO)

Imfuneko epheleleyo yokuphefumla nge-aerobic. I-DO engapheliyo <5 mg/L iphazamisa ukukhula kunye nokuzikhusela komzimba; ukuphelelwa ngamandla (<2 mg/L) kubangela ukuxinana komphezulu ("ukuphefumla") kunye nokufa. Amanqanaba e-larval adla ngokufuna i->6 mg/L. Isebenzisa i-fluorescence-based sensing, i-MPG-6099PLUS inika imilinganiselo ye-DO ukusuka kwi-0–20 mg/L (±2% FS, isisombululo se-0.01 mg/L), iququzelela ulawulo lomoya oluguquguqukayo.

3. Imfuno yeOksijini yeKhemikhali (i-COD)

I-proxy yomthwalo wezinto eziphilayo obolayo. I-COD ephezulu ibonisa inkunkuma yokutya egqithisileyo, ukuqokelelwa kwendle, okanye ukubola kwe-algal—iinkqubo eziphelisa i-DO, ezikhuthaza iimeko ze-anaerobic, kwaye zikhuthaza iintsholongwane ezibangela izifo. Ukubeka iliso rhoqo kwi-COD kwazisa ukwenziwa ngcono kwe-biofiltration kunye nocwangciso lokutshintshiselana kwamanzi.

4. I-Ammonia Nitrogen (NH₃-N + NH₄⁺-N)

Ityhefu enamandla ye-metabolic ephuma ekukhutshweni nasekuboleni. I-Unionized ammonia (NH₃) inetyhefu kakhulu, ingakumbi xa ikwi-pH ephezulu kunye nobushushu obuphezulu. Imida iyahluka ngokwenqanaba lobomi kodwa ngokubanzi ifuna ukugcinwa ngaphantsi kwe-0.02 mg/L NH₃-N kwiintlobo ezinobuthathaka. Ukubeka iliso okudityaniswe nezinzwa kwenza ukunciphisa ngokukhawuleza ngokusebenzisa umoya, ukutshintshana kwamanzi, okanye ukwandiswa kwezinto eziphilayo ngebhaktheriya ene-nitrifying.

5. I-Alkalinity iyonke kunye noBulukhuni obupheleleyo

I-alkalinity iyonke (njengeCaCO₃) ithintela ukuguquguquka kwe-pH kwaye ixhasa i-nitrification; amanqanaba ekujoliswe kuwo yi-≥100 mg/L (ukuzala) kunye ne-≥120 mg/L (ukukhulisa ii-larval) kwi-shrimp aquaculture. Ubunzima obupheleleyo (njengeCaCO₃), obubonisa ubuninzi beCa²⁺ kunye neMg²⁺, buxhasa uphuhliso lwamathambo, ukunyibilika, kunye ne-osmoregulation; uluhlu olufanelekileyo lwe-marine yi-80–120 mg/L. Ukubeka esweni ezi parameters kukhokela ukongeza kwezimbiwa ekujoliswe kuzo (umz., iCaCO₃, iMgSO₄).

(3) Iiparameter ezongezelelweyo zeBiological kunye neContaminant

1. Ukuxinana

Ilinganisa izinto eziqinileyo ezixhonyiweyo—kuquka i-silt, i-phytoplankton, kunye ne-detritus—eziphazamisa ukungena kokukhanya, zinciphise imveliso ye-photosynthetic oxygen, zivale ii-gill, kwaye ziphazamise ukutya. Ukudumba okuqhubekayo >25 NTU kufuna ukungenelela kokuhluzwa okanye ukutsalwa kwenkunkuma.

2. Iintsimbi Ezinzima

Izinto ezingcolisayo eziqokelelana kwindalo (umz., iCu, iHg, iCd, iPb) zibeka emngciphekweni impilo yezinto eziphilayo kunye nokhuseleko lokutya. Imida elawulayo yokufuywa kwezilwanyana zaselwandle ibandakanya iCu ≤ 0.01 mg/L kunye neCr ≤ 0.1 mg/L. Ukuhlolwa rhoqo kukhusela ukuthotyelwa kwemveliso kunye nokuthembeka kwenkqubo yendalo.
