Hoʻohana ʻia nā ʻupena lawaiʻa a i ʻole nā ​​monofilament e ka ulana ʻana (raschel, he ʻupena ʻole ʻole), ka mālama wela mua (nā nodules paʻa), ka waihoʻoluʻu a me ka mālama wela lua (ka nui mesh paʻa).
Hiki ke hoʻohana ʻia no ka lawaiʻa ʻupena drift, trolling, spearfishing, lawaiʻa maunu a me ka lawaiʻa hoʻonohonoho.A i ʻole e lilo i mea maka no ka hana ʻana i nā pahu ʻupena, nā hīnaʻi lawaiʻa a me nā lako hopu ʻē aʻe.
ʻO nā ʻupena i hoʻohana ʻia i ka hana lawaiʻa, ʻo ia ka ʻupena, ʻekeʻupena seine,hoolei upena,upena paa anā hīnaʻi.ʻO nā ʻupena a me nā puʻu ʻeke he ʻupena kaumaha i hoʻohana ʻia no ka hopu ʻana i nā lawaiʻa kai.ʻO ka nui o ka ʻupena he 2.5 a 5 knm, ʻo ke anawaena o ke kaula ʻupena ma kahi o 2 mm, a ʻo ke kaumaha o ka ʻupena he mau tona a i ʻole mau kakini paha.ʻO ka mea maʻamau, hoʻohana ʻia nā moku huki ʻelua e huki kaʻawale i ka hui lawaiʻa, a i ʻole ka waʻa māmā e hoʻowalewale i ka iʻa i loko o ka hui a hoʻopuni iā ​​​​ia.ʻO ka ʻupena hoʻolei he ʻupena māmā no ka hopu ʻana i nā muliwai a me nā loko.ʻO ka nui o ka mesh he 1 a 3 knm, ʻo ke anawaena o ke kaula ʻupena ma kahi o 0.8 mm, a ʻo ke kaumaha o ka ʻupena he mau kilokani.ʻO nā ʻupena paʻa a me nā hīnaʻi he mau ʻupena paʻa i hoʻokiʻekiʻe ʻia i loko o nā loko, nā loko a i ʻole nā ​​kahakai.ʻOkoʻa ka nui o ka maʻamau e like me ka iʻa i hoʻāla ʻia, a mālama ʻia ka iʻa ma kahi wai e pale aku ai i ka pakele.
