1. Ulimi wa m'madzi ndi ntchito yopanga yomwe imagwiritsa ntchito mafunde osaya kwambiri m'mphepete mwa nyanja kulimitsa nyama zam'madzi zam'madzi ndi zomera.Kuphatikizira ulimi wa m'nyanja mozama, ulimi wothirira madzi m'madzi, ulimi wapamadzi padoko ndi zina zotero.Maukonde a makola oyandama panyanja amapangidwa ndi zinthu zolimba komanso zolimba zomwe zimatha kusunga nsomba popanda kuthawa nsomba.Khoma la mauna ndi lalitali, zomwe zingalepheretse kuwukira kwa adani.Kusefedwa kwa madzi ndikwabwino, ndipo sikophweka kuukiridwa ndikuwonongeka ndi adani, ndipo sikudzawonongeka ndi mildew m'madzi a m'nyanja.

2. HDPE zinthu amasankhidwa, ndi zosiyanasiyana odana ndi dzimbiri, odana ndi ukalamba matekinoloje ndi mkulu-mwachangu sanali poizoni odana ndi fouling matekinoloje amatengedwa, amene kwambiri bwino structural mphamvu ya khola, kotero kuti moyo utumiki wa khola. akhoza kuwirikiza kawiri ndikuwongolera kwambiri.Kuchepetsa mtengo watsiku ndi tsiku wokonza ndi ntchito.Makola a m'nyanja yakuya amapangidwa ndi zida zatsopano zokhala ndi mphamvu zolimba zolimba komanso kusinthasintha kwabwino, zomwe zimatha kupirira mvula yamkuntho ya 11 ~ 12 ndi mafunde akulu a 5 ~ 6m kutalika.Pambuyo pa mankhwala odana ndi ultraviolet ndi okalamba, moyo wautumiki ndi zaka zoposa 15.Ukonde umathandizidwa ndi chithandizo chachilengedwe chogwira ntchito komanso chopanda poizoni, ndipo moyo wautumiki ndi wopitilira zaka 5.Onetsetsani chitetezo cha makola ndi kuswana.

3. Deep-sea aquaculture khola limatanthawuza makola a zamoyo zam'madzi omwe angagwiritsidwe ntchito m'madera akuya kwambiri (nthawi zambiri kuya kwa nyanja kumakhala kwakukulu kuposa 20m).Ili ndi pulasitiki yolimba, imatha kulimbana ndi mphepo, mafunde, ndi mafunde a m'nyanja.Ndiwofulumira kuyiyika, yosavuta kuyisuntha yonse, komanso yosamalira chilengedwe.cholimba.Chilengedwe mu khola ndi chokhazikika, thupi lamadzi ndi lalikulu, ndipo liri pafupi ndi chilengedwe;nsomba ili ndi ntchito zosiyanasiyana, kuchuluka kwa moyo, kukula mofulumira, matenda ochepa a nsomba, ndi kuchira mosavuta;nyambo zambiri zachilengedwe, nyambo zochepa;nsomba zotukuka Maonekedwe ake ndi mtundu wa nyama zili pafupi ndi zakutchire.
