Episode 5 - Upyopyo Dive Tsukkome! Umi no Sekai!
Hello, I'm Pikari
Hello, I'm Teko
'Dabukome', which is short for 'Upyopyo Dive Tsukkome! Umi no Sekai! has started!
The fish we'll study today is... krill!
Krill? Isn't it like a tiny shrimp?
Wrong!
A krill isn't a shrimp
Er----
Come on, whiteboard!
It sure looks like a shrimp...
It's a kind of plankton
Really?
Oh? Plankton? The ones that whales consume while swimming with their mouth wide open...
Krill... is part of that
I wonder if whales get enough to survive just by eating those tiny krill
They sure can. Krill is high in nutrients
Blue whales and whale sharks too love krill
How about krill then? Aren't they at risk of extinction if they get eaten by large animals?
Female krill spawn about 6,000 to 10,000 eggs at once so they are not at risk!
Krill also has a secret weapon on top of that!
A secret weapon?
They can survive about 200 days without any food by slowing down the metabolism!
Wow, only if we have that kind of that power
No food for 200 days
No food at all
My grandma's pork soup, giant fried shrimps, cream puffs...
None of those...
No--- Impossible!
Krill is amazing, isn't it?
The freshly caught krill is processed into our food too!
I didn't know that
To think that krill with amazing power is inside of the foods, they look divine now
There is also a fish called Akiami (Acetes Japonicus) which has a very close name to Okiami (Krill)
Akiami? It's almost identical
Akiami is a kind of shrimp unlike krill
That's pretty difficult...
Hey Teko and Pikari
Teacher!
What's with your outfit?
I heard you guys are into fishing now?
No, we are not
We were just studying about krill
That's it!
Listen, krill is an angel that revolutionized the world of fishing
An angel?
It can be used for stab bait and chum. It's inexpensive and can be used for various fish
Mackerel, black bream, red sea bream, striped horse mackerel, sea bream, rockfish, scorpionfish, grunt, horse mackerel, sardines, Hamachi, Ainame, Meidai, Kawahagi, Kanpachi, Hiramasa, Yellowtail, Flatfish, Hokke, etc
In a word, almost all fish bites!
Krill is the dream bait for us, anglers
Krill is the dream!
Why did you say that twice?
Because... krill... Is... dream... bait
That's the 3rd time
I didn't know you are a fisher?
Not that hardcore but yeah
You want to fish too, Teko?
Me?
You will probably have no problem touching krill unlike worm baits
I've gone fishing a couple of times and used krill, but my hands...
Your hands?
Yeah, it stinks
Right?
Yeah
Also, my hands get itchy too
That's because Krills' head, chest, and visceral contains a proteolytic enzyme called protease and this enzyme melts your hand thus it gets itchy
Upyo...
It melts your hands?
I have a sad story to tell...
To tell you the truth, krill is...
Krill is...
When it dies and some time passes, its own protease kicks in to melt its body
No---
The reason why krill left out for a while turns black is the result of self sublimation
It sounds as if... it has a bomb in its tiny body...
Fight, krill!
But their reproducing power is so strong that there is no worry about it as a specie
We've studied that today!
Very well
Alright, I'm gonna go fishing right now
We gotta wrap up too
What will we study in the next episode of Dabukome?
It took the bait!
What!? What is it?
I don't know but I'm going it catch it!
Bye!
