This article is about little fishes that naturally are scared and timid of predators.
But for the fault of human fishing Tuna and Sharks (the principal predators) shrink. Little fishes become bolder: what means that now they take bigger excursions to feed or to go find mates.
In waters untoched by humans, the researches found that the little fish were spotty in their feeding habits.
Using snorkels, scuba equipment and video cameras, a group of scientists captured the behaviour of more than 600 small fishes.
Some parts of the coral reefs, where fish fed on seaweed, where heavily grazed. In other areas, perhaps where predators lurked, there were large tufts of untouched seaweed.
But where fishing was happening, their grazing formed a more even patter across the reefs.
Questions:
Why if humans know about this, they still fishing where there are no supposed to?
Why are not rules in the counties where this happens?

even if they do have rules, they're some cases, well many cases when the people don't care about the rules. i think that if we still behave this way with the earth, some time soon we'll have no more life in our seas, just because of us,the humans.
ReplyDeletethere are no rules in some countries because some really don't know and some of them really doesn't care. I think this has to change making people know this info.
ReplyDeletemaybe they fish it's because of their culture that's the way they grow up and the way they were thought and everyone else in their families.
ReplyDeletei think that countries don't make rules because of how some cultures are different because the generation before was fishing they would be thought as well.
