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.
Compared to the other two species, the European plaice has the most developed scale plate and a rather thick tube wall on trunk l.
Such paired symmetrical platelets of small/young individuals of the European plaice and European flounder are similar, being smooth and having a wide, flat longitudinal ridge.
The ossicles of three pleuronectiforms, the European plaice Pleuronectes platessa, the European flounder Platichthys flesus trachurus, and the turbot Scophthalmus maximus from the eastern Baltic Sea, were described and compared for the first time using SEM imagery.
The distribution of cycloid and ctenoid scales in the European plaice exhibits sexual dimorphism, which was not detected in the other two studied species.
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.
Compared to unstained follicles the use of each stain to color European hake, Atlantic cod, Atlantic mackerel, and European plaice follicles increased the efficiency of image analysis measurement, particularly of semitransparent objects such as PVF, cortical alveoli, hydrated, and POFs.
Although the eosin solution stained both vitellogenic and hydrated follicles in European plaice, it was much less effective when applied to either Atlantic cod or Atlantic mackerel follicles.
Analysis of the data from the 1995 survey indicated that fecundity was overestimated between 11% (Atlantic cod) and 13% for European plaice and common sole (Fig.
