what kind of fish was this

i came across this on tramore beach today well rotten no head.it was about 3ft and looked tuna like in the body what do you think any ideas?

Looks like the remains of a small common Dolphin hard to tell i'm sure one of the fisheries guys will know.... There was small Dolphin washed up on Grattan Beach in Galway recently too.

Looks like a porpoise, a few get washed up along Wexford now and again.

probably a porpoise like dfella said, due to its size.

shore rockling

Done!

Its a Harbour porpoise they get caught in the nets in Tramore Bay the Bay is only about 10m deep and so many get killed that Waterford co. co. have a contractor to remove them but with the cut backs he could be gone must check today. ( many diving birds all so get killed)
