Why are fishermen trawling?
Although trawling, a fishing method that involves dragging a fishing net through the water by boat, is an ecologically disruptive method of fishing, it is also one of the most economically viable fishing techniques. Trawling utilizes large nets which, because they don't discriminate between fish species, catches a lot of bycatch. Bottom trawling, a method in which a net is dragged through the sea floor, is even more damaging (it shatters coral reefs, inhibits seaweed growth, etc.). However, all types of trawling catch numerous amounts of fish in each swipe through. Because it allows fishermen to capture many fish in a small amount of time, fishermen take advantage of it.

What we're the trouble that caused muai's dolphin extinct?
They are critically endangered with only less then 500 left in the wild. One of their biggest threats in the gill nets and fishing nets in the sea. Another threat is bottom trawling. Bottom trawling destroys around 20% of the ocean bottom every time it is used. Bottom trawling not only destroys the dolphin's habitat but also it's food sources'. The food source would decrease because of lack of habitat resulting in the dolphin's population decreasing. The dolphins tend to eat and be attracted to the bycatch of the major fishing boats off of the coast of New Zealand. Since they are attracted to the bycatch, it causes them to move closer to the boats. When they move closer, they increase the risk of a motor accident or getting caught in the gill nets. Hope this helps.. =]
