Among members of the family Pleuronectidae, the mouth of the European flounder is asymmetrical and small but somewhat larger than that of the European plaice.
The lower tooth plates are triangular in the European plaice and European flounder and strongly elongate and rectangular in the turbot.
The number of gill raker rows on arches is similar in the two pleuronectids, with the European plaice and European flounder both having one row on the 1st, 2nd and 3rd arches and two rows on the 4th arch.
The number of gill rakers in the European plaice on the left (= blind) and right (= eye) sides is almost equal, with just a few (1-2) more rakers on the eye side.
He also found that the scales of the European plaice (Pleuronectes platessa) are mostly cycloid, but not infrequently some of them are feebly ctenoid in the male, especially in the small Baltic race.
During the chemical treatment of samples of the European plaice with [H.
Generally the spined scales for the European flounder and European plaice are ctenoid scales.
As shown above, the European plaice has spined scales which belong to the peripheral ctenoid subtype.
Ovarian samples were collected by the four institutes working on two or more of the following species Atlantic cod, Atlantic herring, European hake, Atlantic mackerel, European plaice, and redfish (including deep water redfish and golden redfish) for studies unrelated to this paper (Table 1).
Institute B spread the sample in a counting chamber 70 mm long and either 4, 7, or 10 mm wide for Atlantic mackerel, Atlantic cod, and European plaice, respectively.
ow]), replicate samples were taken by pipette and scalpel, respectively, from the central part of the same ovary from Atlantic cod, Atlantic haddock, and European plaice (Table 1).
An additional data set (Table 1) was also available from an annual egg production survey of Atlantic cod, European plaice, and common sole biomass (Armstrong et al.
6 BL/s reported for European plaice and Japanese flounder (Paralichthys olivaceus) during tidally assisted migration (Kawabe et al.
2004b) noted similar nocturnal behavior for European plaice in the North Sea during winter when two "transporting tides" sometimes occurred within a night because of the longer periods of darkness lasting up to 15 hours.
As with some European plaice, which migrate south to warmer waters for spawning (Hunter et al.
