Fish?

Looking at ARQ's announcement, there is a fish stuck across a section (see below), and they cant remove it. Can someone enlighten me as to whether this is a fish (barramundi, whiting, etc) or a something else.

Do not hold arq, just curiosity

Thanks

Attempts to remove the fish that is stuck across the Dongara/Wagina
section have proved unsuccessful to date and forward plan is to plug
the well and then sidetrack it to a new bottom hole location. Details
on the timing and program for this operation will be made available
when finalised.
