It inhabits in the coastal area north of Yamagata Prefecture and Fukushima Prefecture, and around Hokkaido, Japan. It is characterized by a lack of special morphological features as a flounder, and it is very similar to marbled flounder Pseudopleuronectes yokohamae. The blind
side (white side) has pale yellow lines, but some individuals do not have it (marbled flounder does not have any yellow lines). The small protuberance between the eyes is slippery and scaleless (there are scales on marbled flounder), the overall body
color is brown (green), and scales are larger and its body is thinner than marbled flounder. Eggs are pelagic and non-cohesive. The good fat and delicious from summer to autumn. Good for boiled. Large fish can also be eaten with sashimi (marbled flounder
is also delicious, and in summer it becomes a substitute for the Japanese flounder Paralichthys olivaceus (Temming et Schlegel) as sashimi and sushi).
There are many kinds of fish living in the ocean. We can identify the species by the slight differences in patterns. It is relatively easy to identify the species of adult fish, but it is difficult to identify the species
of juvenile fish. I would like to contribute to SDG 14 (LIFE BELOW WATER) by letting as many people as possible know how interesting and important marine biodiversity is.
The United Nations has designated the decade starting in 2021 as the "Decade of Ocean Science," with the aim of contributing to SDGs. Ocean science, as defined by the UN, includes the field of fisheries.
