Background. Roach, Rutilus rutilus, comprise a large proportion of the total catch in the Szczecin Lagoon, and are caught mainly as bycatch in gillnets targeting perch, Perca fluviatilis. The minimum landing length for roach and perch is 17 cm TL and the minimum mesh size is 30 mm bar length. However, little is known about the selectivity of roach, which may have implications for implementing effective regulations. Consequently, the aims of the study were to estimate roach selectivity curves and to compare the results with perch selectivity. Materials and Methods. The study was based on the length frequency of catch from standardized fishing practice with commercial gillnets of mesh sizes ranging from 25 to 35 mm (bar length) and modelled using various generalized linear models. The best model was selected using deviance criteria. Results. The log-normal selectivity model provided the best fit, with spread relevant to mesh size under the assumption of equal fishing power. The estimated parameters were 18.7 cm and 1.5 (mode and spread of selectivity curve for the smallest mesh size). Conclusion. Although the most efficient mesh size for roach was 26 mm, its use in the Szczecin Lagoon is limited by impact on perch. All the studied mesh sizes prevented catches of undersized roach, while mesh sizes from 28 mm prevented catches of undersized perch (MLL = 17 cm TL). The authors concluded that the current 30 mm minimum mesh size is likely effective at preventing the harvest of undersized perch and roach.

The research was held in terms of Zaporozhian Reservoir (Ukraine) from 2014 till 2015 year. It was established that prussian carp (Carassius gibelio Bloch, 1782) and roach (Rutilus rutilus Linnaeus, 1758) underyearlings accumulate essential elements more extensively, especially zinc, comparing to adults ones. The species characteristic of heavy metals accumulation in the carp fish body was observed. The intensity level of erythropoiesis occurrence was higher in young fish of both species of carp fish. The specific features of cytometric characteristics of fish erythrocytes were identified: the relative amount of mature red blood cells prevailed in roach, and the area of mature red blood cells was significantly higher in prussian carp. In addition, in the young roach among immature forms of red blood cells significantly higher percentage of polychromatophil normoblasts was revealed.

Background. The frequency distribution of oocytes at different maturity phases can be used to assess environmental effects on gametogenesis in teleosts. As oocyte counting is labour-intensive, little attention is generally paid to changes in oocyte numbers in oogenesis analysis. Materials and Methods. Anterior, middle, and posterior ovarian segments from three pre-spawning female roach, Rutilus rutilus (L.) were fixed in buffered formalin, dehydrated, and embedded in paraffin. Serial 10-µm sections were cut with a microtome and stained with haematoxylin and eosin. This paper compares two methods for determining the frequency distribution of oocytes at different maturity phases and their occurrence in particular segments of the ovaries in roach, Rutilus rutilus: counting oocytes in serial microtome sections and the use of Abercrombie′s formula. Results. Differences between frequency distributions determined by the two methods were statistically insignificant (P > 0.05), as were the frequency distributions of oocytes in different ovarian segments. Conclusion. Determination of frequency distribution of oocytes at different maturity phases can therefore be achieved with the less time- and labour-intensive method of using Abercrombie′s formula.

Parasitological examination of 150 young-of-the-year roach (Rutilus rutilus) during winter 2001/2002 in northeast Germany revealed the presence of larval Philometra obturans and Neoergasilus japonicus. This is the first record of roach as a paratenic host for P. obturans, and both records are the first for Germany. There is evidence that P. obturans has been overlooked in previous studies, whereas N. japonicus appears to be a neozoan species originating from Eastern Asia.

Three previously undescribed species of wageneri group of Gyrodactylus Nordmann, 1832 (subgenus Limnonephrotus, Gyrodactylidae, Monogenoidea) related to G. lavareti Malmberg, 1957 are described here. G. pomeraniae sp. nov. was found on roach (Rutilus rutilus) in Poland and Belgium, G. ouluensis sp. nov. on roach in Finland and G. salvelini sp. nov. on Arctic charr (Salvelinus alpinus) in the Lake Inari, Finland. A molecular redescription of G. lavareti on Coregonus lavaretus is also presented, and G. bliccensis on Alburnus alburnus from river Morava, Czech Republic is included in the phylogenetic analysis. In addition, a hybrid clone of maternal G. pomeraniae sp. nov. and paternal G. lavareti found on farmed rainbow trout (Oncorhynchus mykiss) is characterized. The molecular species description was based on the complete CO1 gene of the mitochondrial DNA, and on phylogenetic comparison of the internal transcribed spacer segment (ITS1-5.8S rDNA-ITS2) of nuclear ribosomal DNA. The species hosted by cyprinids were basal in the phylogeny rooted by numerous relatives of wageneri-species group.

During the parasitological studies in Dgał Wielki Lake 32 specimens of Trichodina pediculus were collected from roaches (Rutilus rutilus). T. pediculus were subjected to the metric and meristic measurements. High correlation factors significance was obtained between the following data: body diameter and adhesive disc diameter with border membrane, adhesive disc diameter without border membrane, denticulate ring diameter, height of denticle. However no correlation significance between body diameter and number of denticles was found.

The back-calculation method was applied to determining growth rate of roach caught in the Międzyodrze, Lake Dąbie, Szczecin Lagoon, and the Pomeranian Bay. Samples were collected from April 1995 to October 1997. The Pomeranian Bay and Międzyodrze individuals showed a faster growth rate than that attributed to other stocks. In each of the areas studied, older females grew faster than males. The Odra estuary roach population can be regarded as one of to the fastest growing populations of the species.

The abundance of the spawning population of roach females from the coastal lakes Gardno (2 468 ha) and Łebsko (7 140 ha) located in the Słowiński National Park was estimated for the 1987-1992 period. Following bream, roach is the second most common cyprinid species in regulated fisheries catches. The size of the spawning population was estimated using Virtual Population Analysis and long-term fisheries statistics. Female roach dominated the exploited population at 62.4% in Lake Gardno and 64.3% in Lake Łebsko. During the analyzed period, more roach females were caught in Lake Gardno, which is more than twice as small as Lake Łebsko. Of the generations analyzed (1985, 1986, 1987, 1988, 1989 and 1990), more abundant years occurred in Lake Gardno. The most abundant generation in the two lakes was that of 1985, and following it, each subsequent generation was weaker than the preceding had been.
