Based on the results of comprehensive fisheries research, a brief description of the ecosystem of the lake of the Shaturskaya group operated in the mode of the cooling reservoir of the Shaturskaya GRES is given. The features of the thermal regime of the Shatursky lakes in the zone of the circulating flow of cooled waters are considered. A brief description of the species composition and quantitative indicators of the development of phytoplankton, zooplankton and macrozoobenthos communities is given. The structure of fish catches in the lakes depending on the fishing gear used is considered according to the data of accounting surveys with set nets and fry drag. The process of formation of the ichthyofauna of Shatursky lakes, characteristic of natural and man-made ecosystems of reservoirs-coolers of energy facilities, is shown. The occurrence of native and invasive fish species in catches is described, and the mechanism of seasonal migration of fish depending on the temperature and oxygen regimes of the Shatursky lakes is considered.

A New Species

Abstract Promoting the consumption of edible aquatic invasive species has gained popularity to minimize its impacts while easing pressure on native resources. Weakfish Cynoscion regalis (Bloch & Schneider, 1801) is one of the most recent invasive fish species in the Iberian Peninsula (Europe) which once sustained an important fishery in the native range (Northwest Atlantic Ocean). Portugal ranks third in the list of the world’s top fish consumers, so promoting a weakfish fishery could at least help minimize the impacts upon native species, since weakfish have innate traits that are likely appreciated by Portuguese fish consumers. However, introducing a new species to consumers is challenging owing to consumers’ habits and unfamiliarity with the species. So, we aimed to (i) evaluate the acceptance of weakfish by a panel of Portuguese fish consumers and (ii) create outreach actions – partnerships with local Chefs and press releases – to explain to a broader public what invasive species are and promote the consumption of edible aquatic invasive species. The survey that we conducted to Portuguese fish consumers showed that weakfish has great chances of being well accepted by the public – 90% of consumers would buy weakfish because they appreciated its appearance, flavour, and texture, besides being a wild fish. The outreach actions reached a few million people because 46 online articles were published, and three news pieces broadcasted on national television. Overall, our strategy greatly increased the public’s awareness about invasive species, which can be replicated elsewhere in the world.
