Ka mahiʻai ʻana i ka wai: Ka wā e hiki mai ana o ka lawaiʻa hoʻomau

ʻO ka mahiʻai ʻana i ka iʻa, ka mahiʻai ʻana i nā iʻa a me nā meaola wai ʻē aʻe, ke kaulana nei ma ke ʻano he koho hoʻomau i nā ʻano lawaiʻa kuʻuna. Ke ulu wikiwiki nei ka ʻoihana mahiʻai iʻa honua i nā makahiki i hala iho nei a ke manaʻo ʻia nei e hoʻomau i ka hoʻonui ʻana i nā makahiki he ʻumi e hiki mai ana. ʻO kahi ʻano o ka mahiʻai iʻa e loaʻa nei ka nānā nui ʻana, ʻo ia ka hoʻohana ʻana i nā ʻōnaehana mahiʻai iʻa hou (RAS).

Nā ʻōnaehana Aquaculture Hoʻopōʻaiapuni Hou

ʻO nā ʻōnaehana mahiʻai iʻa hoʻopuehu hou he ʻano mahiʻai iʻa e pili ana i ka mahiʻai iʻa i loko o kahi ʻano i hoʻopaʻa ʻia. ʻAe kēia mau ʻōnaehana i ka hoʻohana pono ʻana i nā kumuwaiwai wai a me ka ikehu, a me ke kāohi ʻana i nā ʻōpala a me nā maʻi ahulau. Kōkua nā ʻōnaehana RAS i ka hōʻemi ʻana i ka hopena o ke kaiapuni o ka lawaiʻa kuʻuna a hāʻawi i kahi lako iʻa i ka makahiki holoʻokoʻa, e lilo ana lākou i koho hoihoi no nā lawaiʻa kalepa a me nā lawaiʻa leʻaleʻa.

Nā Lako Hana Wai

ʻO ka holomua o nā ʻōnaehana aquaculture recirculating e hilinaʻi ana i nā ʻano lako kūikawā, me ka palena ʻole i:

Nā Pahu Wai: Hoʻohana ʻia kēia mau kānana e wehe i nā ʻōpala paʻa a me nā ʻōpala mai ka wai. Hoʻohuli mālie nā kānana pahu, e hoʻopaʻa ana i nā ʻōpala i loko o ka ʻupena ʻoiai e ʻae ana i ka wai maʻemaʻe e hele.

Nā Skimmers Protein: Hoʻohana ʻia kēia mau mea hana e wehe i nā mea olaola i hoʻoheheʻe ʻia mai ka wai, e like me ka meaʻai keu a me nā ʻōpala iʻa. Hana nā skimmers protein ma ka huki ʻana a me ka wehe ʻana i kēia mau mea ma o ke kaʻina hana i kapa ʻia ʻo foam fractionation.
Ua hele lōʻihi nā lako hana mahiʻai i nā makahiki i hala iho nei, e maʻalahi ai a ʻoi aku ka maikaʻi o ka mahiʻai ʻana i nā iʻa a me nā meaola wai ʻē aʻe. Ua wehe ka hoʻomohala ʻana o nā ʻōnaehana RAS a me kā lākou lako pili i nā mea hiki hou no ka lawaiʻa hoʻomau ma ka honua holoʻokoʻa. I ka hoʻomau ʻana o ka ulu ʻana o ka ʻoihana, he mea hiki ke ʻike mākou i nā holomua hou aʻe i nā lako hana mahiʻai e kōkua ai i ka hana ʻana i ka mahiʻai iʻa i ʻoi aku ka maikaʻi a me ka launa pū me ke kaiapuni.
