AbstractThe paper presents the current state of knowledge on dammed lakes in Poland and identifies the crucial research necessities in this area. The analysis of documents concerning dammed lakes and information obtained from institutions responsible for water management in Poland were the basis for a preliminary qualitative and quantitative assessment of dammed lakes located in north-west Poland. This allowed the identification of the necessary directions to be taken in the study of dammed lakes. In many cases, the indicated directions are innovative and have high potential for application.

AbstractCross-industry meta-cluster initiatives may play a crucial role in speeding up conceptualization and launching of viable innovations. In this context, this paper introduces a methodology for integrated planning of hybrid value chains. Using a roadmap of interrelated planning matrices, appropriate projects, mechanisms and institutional constructions can be formulated and cross-industry meta-cluster initiatives can be built in a structured, systematic and systemic way. Theory is exemplified for planning new generations of innovations at the intersection of ICT and agriculture sectors. The case study shows the potential of the methodology to provide a comprehensive qualitative and quantitative assessment of the current state and to highlight the major challenges for reaching a competitive viability of the emerging innovations within a hybrid innovation eco-system.

The article presents annual statistical data of the Caspian Research Institute of Fishery. There has been kept track of the long term dynamics of the stocks of three species of Caspian sprat (anchovy, big-eyed kilka, sprat) and investigated a process of substituting a food item of sprats Eurytemora grimmi to a small-celled copepod species Acartia tonsa Dana. According to the research results, there has been determined growth potential of stocks of each species. Ctenophoran-Mnemiopsis has an adverse effect on sprat population by eating fish eggs and larvae. Ctenophoram - Mnemiopsis is a nutritional competitor to the full-grown fishes. The article gives recommendations on reclamation of stocks of the most perspective species - common sprat, whose biological characteristics helped not to suffer during Ctenophoram outburst and to increase its population during change of the main food item. Hydroacoustic survey data prove the intensive growth of common sprat biomass in the north-west part of the Middle Caspian. According to the results of the research it may be concluded that to realize the volumes of recommended sprat catch it is necessary to organize the marine fishery of common sprat at the Russian Middle Caspian shelf.

Приведены результаты испытания нового перспективного партенокарпического гибрида огурца корнишонного типа F1 Энеж 21, созданного селекционерами агрохолдинга «Поиск», в условиях открытого грунта в Северо-Западном, Центральном и Волго-Вятском регионах Российской Федерации: Костромская, Ярославская, Московская, Рязанская, Тульская область и Чувашская Республика. Высокие потенциальные возможности и адаптационные свойства гибрида F1 Энеж 21 наиболее значимо проявляются в Московской области (63,8 т/га), Чувашской Республике (39,4 т/га) и Рязанской области (31,2 т/га).The article presents the results of testing a new promising parthenocarpic pickling cucumber hybrid F1 Enezh 21, selected by the breedrs of the Agricultural holding «Poisk» in conditions of open ground in the North-West, Central and Volga-Vyatka regions of the Russian Federation: Kostroma, Yaroslavl, Moscow, Ryazan, Tula regions and the Chuvash Republic. The high potential and adaptation characteristic of the F1 Enezh 21 hybrid are most significantly presented in condition of the Moscow region (63.8 t / ha), the Chuvash Republic (39.4 t / ha) and the Ryazan region (31.2 t / ha).
