Because we’ve been (re)reading Cod this school year, I’ve been looking for fish treats, including Icelandic dried fish like the kind my UW classmate Geir brought in one day.  It looked like toenail clippings but tasted like potato chips.  Here’s some.   This could be haddock, or sometimes it’s saithe (Pollachius virens).  Both are gadoids, like cod.  Saithe is also known as coalfish or coley or lieu noir or (with its cousin P. pollachius) pollock.  Actually, it’s so well liked all around the Atlantic that it has many names, and there’s more information here, inlcuding the a clip of the sound they make.  But it might be a little difficult to recognize them that way, so look for a nice straight lateral line instead.
