ʻO ke kuleana o kekahi mau hōʻailona kino a me kemika maʻamau i ka iʻa

E like me ka ʻōlelo, ʻo ka hānai ʻana i ka iʻa ka mea e hoʻoulu ai i ka wai, e hōʻike ana i ke koʻikoʻi o ke kaiapuni wai i ka ʻiʻa.Ma ke kaʻina hana hoʻohua, ʻike nui ʻia ka maikaʻi o ka wai iʻa iʻa ma ka ʻike ʻana i kekahi mau hōʻailona e like me ka waiwai pH, ka amonia nitrogen, nitrite nitrogen, sulfide a me ka oxygen dissolved.No laila, he mea nui e hoʻomaopopo i ke kuleana o kekahi mau hōʻailona kino a me kemika i loko o ka wai.

1.pH

ʻO ka acidity a me ka alkalinity kahi hōʻailona piha e hōʻike ana i ka maikaʻi o ka wai, a he kumu nui hoʻi ia e pili pono i ke olakino iʻa.Ua hōʻoia ka hoʻomaʻamaʻa ʻana ʻo ka pH o ka wai kūpono no ka ulu ʻana o ka iʻa ma waena o 7 a me 8.5.ʻO ke kiʻekiʻe a i ʻole ka haʻahaʻa loa e pili ana i ka ulu ʻana o ka iʻa a make i ka iʻa.ʻO ka iʻa i loko o ka wai alkaline me ka pH kiʻekiʻe aʻe ma mua o 9.0 e loaʻa i ka alkalosis, a na ka iʻa e hūnā i ka nui o ka mucus, e pili ana i ka hanu.ʻO ka pH kiʻekiʻe aʻe ma mua o 10.5 e make pololei ka iʻa.I loko o ka wai ʻakika me ka pH haʻahaʻa ma mua o 5.0, ua hoʻemi ʻia ka hiki o ka lawe ʻana i ka oxygen koko o ka iʻa, e hoʻoulu ai i ka hypoxia, dyspnea, hoʻemi i ka ʻai ʻana i ka meaʻai, hoʻemi i ka digestibility meaʻai, a me ka ulu lohi.Ke alakaʻi nei ka wai ʻakika i ka nui o nā maʻi iʻa i hoʻokumu ʻia e ka protozoa, e like me nā sporozoites a me nā ciliates.

2.Dhoʻoheheʻe ʻia ka oxygen

ʻO ka neʻe ʻana o ka oxygen i hoʻoheheʻe ʻia he hōʻailona koʻikoʻi o ka maikaʻi o ka wai iʻa, a pono e mālama ʻia ka oxygen dissolved i loko o ka wai iʻa i ka 5-8 mg/L.ʻO ka lawaʻole o ka oxygen i hoʻoheheʻeʻia e hiki ke hana i nā poʻo lana, a ma nā hihia koʻikoʻi, e hoʻopilikia i ka uluʻana o ka iʻa a me ka makeʻana o ka pan- loko.ʻO ka mālama ʻana i ka oxygen dissolved lawa i loko o ke kino wai hiki ke hōʻemi i ka ʻike o nā mea ʻona e like me ka nitrite nitrogen a me ka sulfide.Hiki i ka oxygen dissolved lawa i loko o ka wai ke hoʻonui i ka palekana o nā mea hoʻohua a hoʻonui i ko lākou ʻae ʻana i nā wahi ʻino.

1.Nitrite nitrogen

ʻOi aku ka nui o ka nitrite nitrogen i loko o ka wai ma mua o 0.1mg/L, kahi e pōʻino pono ai i ka iʻa.ʻO ka hopena nitrification i kāohi ʻia o ka wai ke kumu pololei o ka hana ʻana o ka nitrite nitrogen.Hoʻopili ʻia ka hopena nitrification o ka wai nitrifying bacteria e ka mahana, pH a me ka oxygen dissolved i ka wai.No laila, pili pili ka nitrite nitrogen i loko o ka wai me ka mahana o ka wai, ka pH a me ka oxygen dissolved.

2. Sulfide

ʻO ka ʻawaʻawa o ka sulfide e pili ana i ka ʻona o ka hydrogen sulfide.ʻO ka hydrogen sulfide kahi mea ʻawaʻawa loa, pili ka haʻahaʻa haʻahaʻa i ka ulu ʻana o nā mea iʻa iʻa, a e alakaʻi pololei ʻia ke kiʻekiʻe i ka make a me ka make o nā mea iʻa.ʻO ka pōʻino o ka hydrogen sulfide ua like ia me ka nitrite, e pili ana i ka hana lawe oxygen o ke koko o ka iʻa, ka hopena i ka hypoxia o ka iʻa.Pono e ho'omalu 'ia ka mana'o o ka hydrogen sulfide ma lalo o 0.1mg/L.

No laila, ʻo ka hoʻopaʻa pololei ʻana i kēia mau mea hoʻāʻo, ka hoʻokō ʻana i ka hoʻāʻo maʻamau, a me ka lawe ʻana i nā ana kūpono i ka manawa kūpono hiki ke hoʻomaikaʻi nui i ke ola o nā iʻa a me nā ʻōpae a hōʻemi i ke kumukūʻai o ka hānau ʻana.
