The Japanese have always loved fresh fish.
But the waters close to Japan have not held many fish for decades. So to feed the Japanese population, fishing boats got bigger and went farther than ever. The farther the fishermen went, the longer it took to bring in the fish. If the return trip took more than a few days, the fish were not fresh, and the Japanese did not like the taste, but of course.
To solve this problem, fishing companies installed freezers on their boats.
They would catch the fish and freeze them at sea. Freezers allowed the boats to go farther and stay longer. However, the Japanese could taste the difference between fresh and frozen and they did not like frozen fish. The frozen fish brought a lower price.
So now the fishing companies came up with another idea and installed fish tanks. They would catch the fish and stuff them in the tanks, fin to fin. Here again, another problem emerged.
After a little thrashing around, the fish stopped moving. They were tired and dull, but alive. And unfortunately, the Japanese could still taste the difference because the fish had lost their fresh-fish taste as it did not move for days. For obvious reasons, the fish-lover Japanese preferred the lively taste of fresh fish instead of sluggish fish.
So how did Japanese fishing companies solve this problem? How do they get fresh-tasting fish to Japan? If you were consulting the fish industry, what would you recommend??
Well, Here's the idea that fishing companies came out with:
To keep the fish tasting fresh, the Japanese fishing companies still put the fish in the tanks. But now they add a small shark to each tank. Yes the shark eats a few fish itself, but most of the fish arrive in a very lively state due to the constant run for their life, and they are lively every moment due to the chase going around!
Have you realized that some of us are also living in a pond but most of the time tired & dull, so we need a Shark in our life to keep us awake and moving? Basically in our lives Sharks are new challenges to keep us active and taste better. The more intelligent, persistent and competent you are, the more you enjoy a challenge. If your challenges are the correct size, and if you are steadily conquering those challenges, you are conqueror. You think of your challenges and get energized. You are excited to try new solutions. You have fun, you are alive!
