The Lower Danube River is an important river both as a navigation pathway that connects Western and Eastern Europe and as a natural environment providing the carrying capacity for a variety of important fish species. In the Lower Danube, the most complex studies on fish fauna inventory date back to Grigore Antipa and Petru Bănărescu. This current s...

Over the years, to maintain navigation along the Danube, the implementation of a series of hydrotechnical works was imposed in order to ensure the continuity of economic activities. Between 2011 and 2014, one such project was built in the vicinity of the county of Braila, on a secondary branch of the Danube-The Caleia branch. The main goal was to r...

In the Lower Danube, sturgeon populations have declined dramatically in recent decades. Although efforts have been made at the legislative level since 2006, by forbidden commercial fishing, an assessment of stocks and conservation status of sturgeon species has not yet been made. In this context, it is necessary to estimate the age and growth rate...

The Black Sea sturgeons are anadromous fish species, which migrate upstream on the Danube River for breeding. The distance traveled in the migration process varies depending on each species, from tens to hundreds of kilometers . After breeding, the anadromous sturgeons return to the Black Sea and go back to the Danube after a time that varies depen...

The sturgeon species are a flagship species of the Danube River Basin that acts like an indicator of ecological health. They are protected by several international conventions (CITES, Habitats Directive, the Bern Convention and the Bonn Convention) and are assessed as endangered by the IUCN. Starting from 2011 the National Institute for Research an...

Anthropogenic activities can lead to the contamination of freshwaters with heavy metals, which are some of the most persistent pollutants in waterbodies, due to their difficulty to degrade. These pollutants can be accumulated in sediments, aquatic macrophytes and other aquatic organisms, leading to ecological disturbances and potential human health...

Connectivity is now recognized as a fundamental property of all ecosystems. In this study, the effects of temporarily connection loss of the Epurasu branch, caused by low flows and the emergence of sandbanks throughout its length, were investigated. In this context, scientific fishing activities, water sampling, and measurements for the determinati...

Biometrical data of the migrating population of Pontic shad Alosa immaculata Bennet from the Romanian sector of the Lower Danube is analysed. The surveys were done by the National Institute for Research and Development in Environmental Protection-Bucharest between 2011 and 2018 during the spawning migration. In total, 286 individuals have been exam...

To acquire precise data on the hydrodynamic parameters is of major importance for the characterization of a watercourse. In this regard, specialized techniques have been developed and used in order to measure, process, analyze and forecast the data which define the watercourse, such as: riverbed bathymetry, flow, water level and water current veloc...

Sturgeon species are listed as some of the oldest species, adapting continuously to the various natural changes in their living environment. On the territory of Romania there were 6 sturgeons species of the genus Acipenser and Huso, but due to anthropogenic influences, it seems that two of the six sturgeon species are extinct, namely Acipenser nudi...

The importance of the sturgeon species conservation has conducted to the development of numerous research projects to complement and improve the current knowledge of the behavior of these species. The sturgeon anadromous migratory species are sensitive to hydromorphological changes, which is of particular importance for the monitoring of their beha...

The monitoring carried out by the INCDPM team for sturgeon species during the period 2011-2016 showed that upstream migrations of the beluga specimens it is realizing in 98% on the Borcea branch and only 2% on the Old Danube (km 248-345) and in proportion of 96% on Borcea and 4% on the Old Danube in the case of the stellate sturgeon species. Given...

Sturgeon are cartilaginous bony fish species appeared more than 200 million years ago. Four of this species are still found today in the Black Sea and the Danube River. Historical data and archaeological discoveries show that fishing for this species dates back more than 5000 years along the Danube. However, a multitude of anthropogenic factors has...

Project
Starting with 2017, INCDPM is developing a project in the areas of Borcea-Bala-Epurasu Branches and the Old Danube. The main objective of the project is to monitor the ultrasonically tagged sturgeons after catching and relesing them. At the same time, 2D and 3D bathymetric measurements are performed, in order to elimitate the risk of interrputing the sturgeon migration routes and to identify the feeding, breeding and resting areas of the sturgeons. In this regard, besides the use of the fixed and floating monitoring stations, there are carried out monitoring actions with the VR 100 mobile equipment, in order to obtain a complete informational volume regarding the sturgeon behaviour during migration and to protect them against poaching. This project provides an unique informational volume at global level regarding the sturgeon behaviour and new and important results consisting of complex maps developed on the basis of multidisciplinary decisional analysis.
