The ossicles were taken from 20 specimens each of Pleuronectes platessa Linnaeus and Platichthys flesus trachurus (Linnaeus) of the family Pleuronectidae, subfamily Pleuronectinae, and Scophthalmus maximus (Linnaeus) of the family Scophthalmidae.

In this paper we have presented our results on three members of the Pleuronectiformes (flatfishes): the European plaice Pleuronectes platessa and the European flounder Platichthys flesus trachurus, both in the family Pleuronectidae, and the turbot Scophthalmus maximus of the family Scophthalmidae.

, can sustain annual commercial harvests well in excess of 2 million metric tons (t).
Here we compared Pacific cod to smaller-bodied species of fish--Cottidae, Hexagrammidae, Pleuronectidae, and Oncorhynchus.
During this time, the AIs for Pleuronectidae and Hexagrammidae indicated a slight decline in relative abundance of Pacific cod, whereas the Cottidae index indicated a greater decline in Pacific cod abundance.
Microspectrophotometry studies of other members of the family Pleuronectidae
(Platichthys flesus [flounder] and Pseudopleuronectes americanus [winter flounder]) show that the peak absorbance of the photopigment in rod cells is [approximately equal to] 510 nm, that in single cones is [approximately equal to] 450 nm, and that in double cones is [approximately equal to] 530 or 550 nm (Evans et al.
The family Pleuronectidae had the greatest number of taxa (9), followed by the family Cottidae (6).
The unidentified Pleuronectidae eggs were of four species (butter sole [Isopsetta isolepis], English sole, starry flounder [Platichthys stellatus], and sand sole) which cannot be identified to species at early egg stages.
More than half of all species included in the egg-stage cluster analysis were flatfish from the families Pleuronectidae and Paralichthyidae (Fig.
