In 2003 trof de Vlaamse Milieu Maatschappij (VMM) bij een waterkwaliteitstaalname in de
Dorpbronbeek een rivierdonderpad (Cottus sp.) aan. In dit bovenloopje van de Kleine Gete nabij
Linter komt de laatste (gekende) natuurlijke rivierdonderpadpopulatie van het Demerbekken op
Vlaamse bodem voor. Door de beperkte afmetingen van de beek en de toenemen...
Het NARA-2020 is een naslagwerk met feiten en cijfers voor het beleid. Het beantwoordt vragen als: hoe is het gesteld met de biodiversiteit in Vlaanderen? Wat zijn de belangrijkste drukfactoren? Heeft Vlaanderen de regionale en Europese beleidsdoelen voor 2020 behaald? En welke aanbevelingen kunnen we daaruit afleiden?
The indicators in this Nature Report give an idea of the state of and trends in biodiversity in Flanders, describing the pressures involved and their effects on our ecosystems. The six targets of the EU biodiversity strategy are evaluated. Recommendations are based on the EU biodiversity strategy 2030.
This report represents an extended version of the chapter on Invasive Alien Species of the
Flemish State of the Environment report 2020. Invasive Alien Species represent a growing
threat to biodiversity and ecosystem services in the region. This report describes the current situation of introductions and impact of alien species in Flanders and revi...
Bij visserijkundig onderzoek naar moeilijk waarneembare vissoorten wordt er, naast de klassieke vangstmethodes (elektrisch vissen, fuiken), steeds meer beroep gedaan op out-of-the-box methoden. Denk maar aan vrijwilligers die gewapend met zaklampen donderpadjes gaan inventariseren, aan snorkelinventarisaties in heldere waterpartijen, maar ook aan h...
Microhabitat suitability models are useful tools to enhance the reintroduction success of fish. Since 2008, a translocation and reintroduction program has been carried out in Flanders to prevent substantial loss of genetic variability in the Cottus perifretum (bullhead) population, and to meet the goals set by the Habitat Directive. To this end, ha...
Bullhead is a small, bottom-dwelling freshwater fish species. It used to be common in Flanders (Belgium) but nowadays only few and isolated populations remain. Consequently bullhead is listed as IUCN susceptible in the national Red List and fully protected. It is also listed in the EC Habitats Directive (92/43/EEC). Management should aim to conserv...
Het Handboek voor beheerders - Europese natuurdoelstellingen op het terrein wil als
publicatie bijdragen aan de realisatie van de Europese natuurbehoudsdoelstellingen,
de zogenaamde natuurdoelen.
Het idee voor dit handboek kreeg vorm in de vergaderingen van de Vlaamse Overleggroep
die de uitwerking en de realisatie van de natuurdoelen op Vlaams niv...
Bullhead is a small bottom-dwelling freshwater cottid. It is endangered in most of Western Europe. Consequently it is listed in the EC Habitats Directive 92/43/EEC. In Belgium two indigenous species occur: Cottus perifretumin the Scheldt River drainage and Cottus rhenanusin the Meuse River drainage.
De rivierdonderpad is een klein zoetwatervisje dat behoort tot de familie van de Cottidae en goed aangepast is aan zijn leven als bodembewoner. In België komen er van nature twee rivierdonderpadsoorten voor: Cottus perifretum, in het stroomgebied van de Schelde, en Cottus rhenanus, in het stroomgebied van de Maas (Volckaert et al., 2002). Vroeger k...
Until 2003 Cottus perifretum was believed to be extinct from the Demer River basin in Flanders, Belgium. However, that year a relict population of this bullhead species was found in the Dorpbronbeek. The Research Institute for Nature and Forest (INBO) and the Agency for Nature and Forests (ANB) launched a conservation project to preserve this popul...
A feeding trial was conducted to study the effect of different diets on growth and survival for larvae of dace, Leuciscus leuciscus under controlled culture conditions. Two days after hatching, the larvae were exposed to different feeding conditions: (i) freshly hatched Artemia nauplii, (ii) dry decapsulated Artemia cysts, (iii) crumble carp starte...
The use of decapsulated Artemia cysts as food for ide, Leuciscus idus (L.), larviculture was investigated. Three days after hatching, the larvae were fed on different diets: (a) dried decapsulated Artemia cysts, (b) Artemia nauplii, (c) Artemia nauplii for 7 days and then trout starter, (d) diet for marine larvae (manufactured artificial diet), (e)...
The burbot (Lota lota) is the only fresh water member of the cod family, Gadidae, and is adapted to cold waters. The effects of temperature and light on the growth and survival of burbot larvae were investigated under hatchery conditions. Three temperature regimes (12, 16 and 20°C) were applied under continuous light and darkness during the experim...
Summary Burbot Lota lota L. is one of the endangered freshwater fish species in western Europe for which the development of controlled larval rearing procedures could produce enough material for stock enhancement. The suitability of the freshwater rotifer Brachionus calyciflorus as a start food for larviculture of burbot was investigated. After yol...
Little is known about the larviculture of the chub, Leuciscus cephalus (L.), an endangered cyprinid species endemic to European flowing waters. The use of decapsulated Artemia cysts as food for chub larviculture was investigated. After 3-day feeding with the rotifer Brachionus calyciflorus, the larvae were fed on different diets: (i) dried decapsul...
