A tuna died at aquarium in Japan.That's an affair in time of a food doing show. Suddenly, it collided at the center of the water tank. Staff have said theTuna caused brain concussion. This movie are English subtitles.
There’s a reason why most aquariums don’t have fish that live in open waters. Great white sharks, mako sharks, tuna, marlin, sword fish, mahi-mahi, tuna, etc. They live in this huge space where they almost never have to turn to avoid obstacles. Then suddenly you put them in a very small tank which forces them to turn around over and over again as they swim. This is why almost no aquarium has successfully kept a great white shark, but many successfully keep bottom dwelling reef sharks.
While most of what you said is true I don't think it is the case for these fish. These tuna have ample room to move and wander in this aquarium. This happened because the feeding display caused a feeding frenzy and with fish darting every which way one happened to strike another. This type of thing happens in the wild as well.
Thank goodness for the translator, otherwise I would never have known the outcome, even if it was a sad one - I figured stunned, but would eventually shake it off & rejoin the group, I certainly never expected it to go from stunned to just dead. Wow 😳
If you watch it in slow motion, it wasn't the impact of the two fish that made the rest scatter. They started to scatter a split second *before* the fish got hit. The sudden change in direction was *why* the fish got hit. So what I want to know is, what was it that really happened to make all the fish freak out like that in the first place?
After reading different explanations, I still don't understand what killed this fish. I still half wonder if he was just stunned. It doesn't make sense to me. So weird. I've watched it several times in slow motion. I wonder if being flipped over shocks them, or messes with their swim bladder. I'm by no means an expert. I'm a casual betta hobbyist, but I still have lots to learn there too.
It’s just sad. I’m sure all of those fish would rather take their chances in the ocean than be trapped forever in a tank, especially one too small for them.
Tuna are stupid. Even if you released them, they would swim in circles until they beach themselves. That is what happened when a boat damaged the nets on the tuna pen and the tuna escaped. They swam in circles until they beached themselves on Imperial Beach. People were running around in the rain catching tuna stuck on the beach. The name of the tuna that hit the aquarium is called "sashimi".
Fish are sentient beings whose capacity to suffer is no less than human’s. They weren’t born to entertain, they have individual lives which they have every right to live, just like you. Btw, massive numbers of people in this world are objectively “stupid” and still roam free without condemnation to lives of confinement.and sorrow.
The tuna went catatonic as soon as it got flipped up belly up from the collision. Died shortly there after. This happens even if its not as strong. Its like they can choke if they are in a wrong a angle in the water
The inordinate damage that collision did to the stunned fish shows exactly how unhealthy this environment is for pelagic species.... SHAME on keeping these magnificent fish in an aquarium
They think they're "just fish." They're APEX PREDATORS! We all must to understand this creature is as critical and precious to the ecosystem as polar bears, lions, tigers, crocodiles, and orcas. It is ont any old fish. And yet we have fished/eaten this kind of tuna to virtual extinction. People don't talk about this enough.
Crazy that small of an impact could cause that much blood loss. At around 1:38 you can really see this fish is bleeding quite a bit and will probably be on ice in a few minutes.
Fish have this lateral line that prevents them from hitting one another when they are schooling. What killed it is a collision with the other fish n not the glass of the aquarium. The dead fish was going left to avoid the collision but the glass is in the way so it has no choice but to hit the other fish n a fatal collision at it.
Only thing I can think of is the other tunas pectoral fin found its way into the other tunas gill plate when they collided. The heart is right behind the gills so it's a possibility.
