Don't know exactly but temps got over 30oC so I partially covered tank with shade cloth for summer.qldmick Wow, nice bunch. What temps do you keep yours at, especially the high end? I assume you are in Queensland?
Sorry to hear Vik, my condolences with you. My cod has grown substantially, but in an u heated 68 degree tank. I hope we can figure out what has happened!!!!Unexplained loss. Thought there could be a physical obstruction to eating but non found. Grew from 3" to 7" in 6 months, eating well only for 5 months or less.
Vik, this is a low blow. I’m sorry. I would not like to see you be done though. I really hope we can understand why this happened and how to prevent this. I think these 2, they looked though they’re targeted by the same death, which was high temps. Breathing heavily is a sign of their body trying rapidly to almost cool down although that’s “scientifically” not true. I do not want to see you not try at least one more time. If you wouldn’t mind, I’d love to buy cod for you next time or getting a chiller, I think what you do is amazing, so if I or anyone can help any way we’d love to.Game over. I am done trying. 2 tries 2 fish each, one in 2015-2017, second in 2023-2024. Same result. 4 dead cod.
I conclude 80F is deadly. Probable safe max maybe 75F. Wes says the Taiwan farmer says 86F is still okay. Bad disagreement.
9 inches. 8 months old.

Yeah 100% was temps. They just don’t liken it hot. Warm for that matter. They stress easily as well so you’ve probably got the two biggest killers up against them.Vik, this is a low blow. I’m sorry.

I don’t let mine get above 72. I gotta say Wes was wrong on this one.Yeah 100% was temps. They just don’t liken it hot. Warm for that matter. They stress easily as well so you’ve probably got the two biggest killers up against them.
Calling bull on old mate about them being okay at 30. Maybe for a couple of days but not much longer than that.
Yeah i haven't ever heard of cod being kept that warm. Hatcheries here breed at 20 C. 24 is about the max i've heard of.I don’t let mine get above 72. I gotta say Wes was wrong on this one.
