The age and rate of growth of the flounder from inshore shallow waters of the Gulf of Gdansk (from shore to 1-m depth) have been investigated. Mainly the flounder from 0 and 1-year age group exists in this zone. Flounders from 0-year age group enter shallow waters of the Gulf of Gdansk in June or July. They stay in this area till the end of the year. Flounders from 1-year age group are represented in the investigated zone all year. Bigger individuals from this group migrate into deeper waters.

On a basis of whole year monthly sampling, the abundance of the flounder in inshore shallow waters of the western part of the Gulf of Gdansk was established. Flounders were observed almost all year. Only in winter, when sea ice forming proc-esses occurred, they disappeared from the investigated zone. The highest abundance of the flounder was noticed in Hel vicinity. No flounders were observed in inshore waters of the Puck Lagoon. Young flounders occurred in the highest number in July (average for all investigated area amounted to 2.81 individuals 100/ m^2). In that month, this-year-born flounders settle in the inshore shallow water zone. The highest biomass was noticed in August (average 4.98 g/100 m^2) when older bigger flounders more frequently inhabited inshore zone. Body proportions of young flounders during their growth in inshore shallow waters of the Gulf of Gdansk are stable. All measured distances were increasing linearly with the growth of flounder length.

One of the most crucial challenges in a modern civilization, is environment protection, which constitutes natural life fundament, including all human activities. In the second half of the twentieth century, it became certain, that continuing current, narrowly understood economic development will not ensure a stable improvement of economic, ecological and social conditions, both for present and future generations. Problems such as depletion of non-renewable resources, an endangerment of renewable resources (e.g. intensive fishing leading to species extinction), overpopulation, environment pollution on a global scale and connected with this fact, an impact on human health, species diversity and natural landscapes, global warming, the change of consumption models from resource-efficient and concentrated on spiritual values, and long periods ones into wasteful ones, and the ones which are directed into material values and extemporary, an increasing risk of control of most world markets through international corporations, all these lead to life quality deterioration. An alternative development conception is sustainable development. The accomplishment of sustainable development requires a change towards managing process and that is why, many economists postulate for a replacement of neoclassical assumptions of economics by the economics of sustainable development. Neoclassical economics treats natural resources as one of the production factor, and its aim is their optimal usage. However, the aim of sustainable development is so called sustainable managing, which effect is a guarantee of economic, ecological and socio-cultural standard of current and future generations on a natural level of nature resistance. It means that natural capital in the conditions of passing time and generations’ succession should remain stable or increase. Sustainable managing requires applying many various means and instruments, which can be aligned to three strategic paths of the economics of sustainable development: Effectiveness strategy – assumes tenfold increase of resources efficiency; already existing products are formed in a way, which makes the use of resources to be a more efficient one (including the reduction of pollution emission); Cohesion strategy – new products are worked out, the products, which satisfy sustainable development requirements; Sufficiency strategy – means voluntary deciding on a gradual change of people’s own life in a socially responsible way i.e. developing, according to inter-generational and intra-generational principle of justice. It is mainly about limiting the consumption of natural resources, because the tolerance borders of nature have already been exceeded. The aim of this article is the analysis of the usability of marketing concept to the accomplishment of strategic paths of the economics of sustainable development. One of the key issues, which pervades current representatives of the economics of sustainable development, is looking for the tools for the accomplishment of strategic paths. A universal tool, which can be used in those three strategies is sustainable marketing, defined as a process of satisfying consumers and society’s needs through planning and making conceptions, prices, promotions and distributions of ideas, good and services real, in such a way that satisfies the exchange of counterparties and which is sustainable at the same time. Such an understanding of marketing includes both view point of recipient and society, whose aim is to integrate economic, ecological and socio-cultural benefits. The conception of sustainable marketing can be used by each socio-economic entity, both for-profit and non-profit. The accomplishment of the effectiveness strategy, first of all, requires a proper redesigning of current products and then the products should bring success on the market. However, the cohesion strategy is based on so called eco-design of new products, forming unconventional solutions and providing recipients for them. Both strategies are becoming more popular, because they interfere only a little bit with the existing socio-economic system. They also allow to implement changes in an evolutionary way and give the engaged counterparties time for preparation to new requirements. That is why, they are accomplished within marketing organizations for-profit activities. Whereas, the efficiency strategy is still unpopular. Within this strategy, sacrifices, social responsibility, ethical actions, attitudes and behaviours’ changes – often of revolutionary character, are required from all socio-economic entities. This strategy is often accomplished by non-profit organizations, and its effectiveness mostly depends on the level of sustainable marketing conception usage.

This paper is focused on the determination of three hexabromocyclododecane isomers, α, β, and γ, in the tissue of the most commonly consumed marine and farmed fish in Central Europe. The analytical procedure contains multiple steps: extraction, dialysis using semipermeable membranes, and a clean-up step using a silica gel column. Hexabromocyclododecane (HBCD) isomers were determined by sensitive isotope dilution liquid chromatography-tandem mass spectrometry (LC-MS/MS) method which is characterized by a low limit of detection (1 pg g -1 fresh weight). The recovery values obtained for individual isomers were in the range of 89–124%. The γ-HBCD isomer was detected in all samples. This isomer also had the largest percentage in comparison with the other isomers, except in salmon, in which the α-HBCD isomer was more abundant. The highest level of total HBCD was measured in mackerel (650 ± 195 pg g -1 fresh weight). Cluster analysis allowed the differentiation of groups of objects and the display of objects based on the degree of integration within the same group. Spearman’s rank correlation indicated no statistically significant difference between the levels of HBCD and the fat content in the fish samples.

Acoustical monitoring of fish at an electric barrier was performed using EY 500 split beam echo-sounder with the transducer directed horizontally. Stationary measurements done during the operating barrier and when the electric power was switched off have shown statistically significant difference in the number of fish approaching the barrier, 11 fish in the first case, and over 280 in the second. The electric barrier affected more strongly large fish than the small ones. Mobile measurements performed in a basin from which fish were approaching barrier revealed the higher fish concentration just in front of the operating barrier than elsewhere.

During over thirty years of development of echosounders, the acquisition software has developed different kind of charts for data visualization. In the paper the concept of creation of dynamic echograms from the data acquired in acoustical surveys is presented. As the modern split-beam echosounders allow for nonambiguous localization of targets in the water column, it is possible to visualize them in 3D coordinate system. Virtual Reality Modeling Language VRML is a popular language used in modeling of virtual reality. Using its build-in properties, it is relatively easy to visualize movement of fish treated as an object in any coordinate system. VRML despite the typical application in computer graphics is also used in other various fields. For instance in chemistry it is used for visualization of atom particles, in medicine for modeling of human organs, in astronomy for visualization of trajectories of the stars and in geography and navigation for creation of 3D maps. Hence, in this paper we describe its application in fisheries. Additionally, as the any WWW browser can be equipped with VRML plugin 3D fish visualization can be redistributed in the Internet.

A total of 136 fishes, representing 9 species (perch, Perca fluviatilis L.; pike, Esox lucius L.; European eel, Anguilla anguilla (L.); common bream, Abramis brama (L.); roach, Rutilus rutilus (L.); tench Tinca tinca (L.); European whitefish, Coregonus lavaretus (L.); vendace, Coregonus albula (L.); and zander, Sander lucioperca (L.)), from Lake Miedwie were studied within 1997-1999. The necropsies yielded 41 parasite species (taxa). The most diversified were parasite faunas of pike (19 parasite species) and perch (16 species) The parasites found represented 13 higher taxa: Monera, Fungi, Protista, Myxozoa, Monogenea, Cestoda, Digeoea, Nematoda, Acanthocephala, Branchiura, Copepoda, Mollusca, and Acarina. The parasites affecting fishes of Lake Miedwie exbibited diversified host-specificity. The most fish species were infectcd by metacercariae of Diplostomum spp. (8 fish species) and Tylodelphys clavata (1). Three fish species harboured: Ichthyocotylurus platycephalus, Ergasilus sieboldi, and glochidia Unionidae gen. sp. white Dermocystidium sp., Trichodinella epizootica, Henneguya psorospermica, Triaenophorus nodulosus, Posthodiplostomum cuticula, and Camallanus lacustris parasitised two host species. The remaining parasites were found in single fish species.

The comparative studies were performed on insulin receptors of erythrocytes and liver plasma membranes in fish (tench and carp) and bird (duck). The Scatchard plots indicated the presence of two pools of binding sites both in fish and duck. These pools show inter-species differences in binding ability and the number of receptors. Specific binding of insulin and the binding affinity are higher in duck than in fish.

Total trace element concentrations and their binding forms were studied in benthic sediments and in roach (benthivore), bream (planktivore/benthivore), and pikeperch (piscivore) in the upper and lower sections of the Dobczyce Reservoir in southern Poland. The sediment was polluted to a low degree by Cd and relatively unpolluted by Pb, Zn, Mn, and Fe. According to the index of geoaccumulation (Igeo), Cd was the most mobile element in the sediment and was bioconcentrated in fish tissues to the highest degree, especially in roach, which feeds by burrowing into the sediment. The trace element distribution in fish tissues (muscle, liver, kidney, and gills), fish species, and in fish from different locations is discussed.

This study aimed to develop a chromatographic method to quantitatively determine phenol in fish tissues. This method involves solvent extraction of acidified samples, followed by derivatization to phenyl acetate and analysis with gas chromatography coupled with mass spectrometry (GC–MS). Phenol in a representative tissue sample (belly, gill, or renal tubules), which was homogenized with 2 N sulfuric acid, was extracted with ethyl acetate and derivatized to phenyl acetate using acetic anhydride and K2CO3 in water. An n-butyl acetate extract was injected into the GC–MS. The linearity (r2) of the calibration curve was greater than 0.996. The analytical repeatability, which is expressed as the relative standard deviation, was less than 6.14%, and the recovery was greater than 96.3%. The method detection limit and the limit of quantitation were 8.0 μg/kg and 26 μg/kg, respectively. The proposed method is also applicable to the analysis of other biological tissues for phenol and its analogs, such as pentachlorophenol.

Epizoic diatom communities were studied on four turtle species (Chelonia mydas L., Eretmochelys imbricata L., Lepidochelys olivacea Eschscholtz and Dermochelys coriacea Vandelli) from the Eastern Caribbean, the Equatorial West Atlantic and the South Pacific. In the present study, we focused on one taxon of Navicula Bory de Saint-Vincent, described here as a new taxon, which was found on seven individuals of Dermochelys coriacea and one individual of Lepidochelys olivacea in French Guiana. The new Navicula taxon was found neither on Chelonia mydas (83 specimens examined) nor Eretmochelys imbricata (13 specimens examined). Furthermore, the new taxon appears to have a restricted biogeography, as so far it has only been reported from French Guiana. A species of Navicula is reported for the first time as a supposedly exclusive epizoic taxon. Navicula dermochelycola sp. nov. is characterized in detail; its ultrastructure is described and compared with other members of Navicula.
