Rock Sole Description (Lepidopsetta bilineata)

Rock Sole are actually a right-eyed Flounder and not a Sole, but are called “Sole” because the word is more marketable. They are found with a number of color variations on their upper side including grey, olive green, dark brown or black all with various shades of marbling. They may also have red or yellow spots. Although they can weigh up to 5 pounds, average commercial catch weight is about 2 lbs for a whole Rock Sole.

There is a large Japanese market for their roe so the majority of the catch is fished from January to March when the females have eggs.

Hi. I was looking at your site and noticed that whenever you make reccommendations on what is the “best choice” for a species of fish, it is always US caught fish as apposed to other countries. Typical for Americans to avoid recognizing Canada as a coutry that share the same oceans and also the same border. How is Alsaka caught Halibut different than canadian caught Halibut. Both are from the same geographical region and waters and both are biologically exact.

If you are looking for reasons to list Canada as well of the US for species of fish we both share in both our waters, then you must look at the tracvk record for Canadian fisheries laws and regulations as apposed to US mainly Alsakan reputation. Alaska has a long history of doing what they want and have been known to overfish and disragagrd any attempt by Canada to regulate the fisheries and thereby manage the resources wisely. Whether it be salmon, halibut, or otherfish, Alaska is know and always have been based there quotas on greed and indifference to the warning signs displayed ny both Canadian as well as US scientists.

I personally know a few Alaskan fisherman who seem to think that the fish in the ocean will never die out and they believe that if they don’t catch the fish in the sea, someone else will and they will lose money. At the end of the day in Alaska, it is always about the money and human greed instead of conservation of the stocks for future generations as well as present. Perhaps you can use the California, Oregon, and Washington salmon histories to see what Alaska is still doing today. How are your salmon stocks in those States today? I rest my case.
