Hunting for survival and food, ok. Fishing, even a shark...if it's for food or survival, ok. As long as the kind of shark you catch is not an endangered or threatened species.
The way you catch them...doubtful. I can only imagine how much you have to exhaust end hurt these animals before they actually die. Not ok.
I'm not vegetarian, I eat meat and birds. But I try to be aware of how the animals are killed. No foie gras for me out of principle.
Fish, I don't eat but because of allergy reasons.
What I do NOT agree with in any way is killing for fun or sports!
