Chapter 393 - 196: Catching Coconut Crabs_4
After hoisting it onto the yacht with a strong pull, Lin Yang noticed that the fish was already near death, mainly because this type of fish has a particularly small opercular bone area, sparsely distributed gill filaments, and thus a poor ability to exchange oxygen.
As soon as this fish was taken out of the water it would die, unlike belt fish, which can be brought aboard alive if you lift it slowly to let it adjust to the water pressure. This fish couldn’t survive.
Seeing the fish was on the verge of death as soon as it surfaced, Lin Yang didn’t pay it much attention. After all, he had planned to cook and eat it for lunch.
However, before cooking it, he decided to introduce this Ma You Fish to the viewers first.
"Many people probably don’t know how to distinguish between wild and farmed fish, do they? Now I’ll teach you." After taking the Ma You Fish off the hook, Lin Yang looked towards the live stream audience and began the introduction.
"Although these methods aren’t applicable to all fish, they do apply to many. The first is to look at the body shape; among fish of the same size, those that are slimmer and longer are more likely to be wild. Second, look at the color; wild fish are usually brighter than farmed fish.
The third and most important is to look at the fins. Wild fish need to swim continuously to search for food, so wild fish fins must be well developed. The standard for developed fins is that they must be long enough.
Because farmed fish get food handed to them, they don’t need strong swimming abilities, so their fins tend to be shorter.
For fish like Ma You and Yellow croaker, the simplest way to determine if they’re wild is to fold their fin towards their eye. If the fin covers more than half of the eye, it’s very likely that the fish is wild.
