Tuna are most definitely smaller than Dolphin. Therefore I would have thought that any net that could catch a Tuna could also catch a Dolphin. Flaps in nets would allow the intended catch to escape.

I was thinking this question only yesterday! How strange! I'd like to know the answer to this one too. I thought Tuna were smaller than Dolphins, so they can't escape through holes in the net.

Tuna is Big also but not that big as a Dolphin if you catch a tuna you need a really big net and if you catch a dolphin you need a double really big net.

In 1990s tuna fleets were forced to clean up their act by fitting all nets with special hatches through which accidentally caught cetaceans could escape.

Tuna are very big fish, so they make the nets with large enough holes that the dolphins can swin through, but the Tuna cannot.

They attach water-proof mp3 players to every knot in the net, and these players say pleasant happy things in dolphin language for any nearby dolphins....
