Abacwaningi bazama ukuthola imbangela yokufa kwabo, futhi enye indlela okuhlolwa ngayo iwukudliwa ushevu. Okungachaziwe: Imbangela yokufa kwezinhlanzi ezingaphezu kuka-150 iyahlolwa, kodwa okwamanje ayaziwa.

Kucatshangelwa ukukhanyiswa kwethangi nezinye izici okungenzeka zabangela ukucindezeleka kwezinhlanzi, noma ukuba khona kwento enobuthi emanzini. Leli thangi elingamathani angu - 2 200 lalikade liqukethe ama - bluefin tuna angu - 69, ama - little tuna angu - 52 aseMpumalanga nama - bonito angu - 38.

Waphuka umgogodla, okuyinto edabukisayo kodwa engajwayelekile kakhulu ngethoni eligcinwa ethangini. Ukuhlola kwangaphambilini kutholile uhlobo oluthile lwegciwane phakathi kwezinhlanzi ezifile, kodwa kwakungelona uhlobo oluvame ukubulala emapulazini ezinhlanzi.  <response>: Izinhlanzi ezingaphezu kuka-150 zafa e-aquarium yaseJapane futhi kwasinda eyodwa kuphela.
