LIFE SAVING LASCA Urgent measure to conserve nearly extinct species Protochondrostoma genei

PROJECT DESCRIPTION

BACKGROUND

South European nase (Protochondrostoma genei) is a fish species that inhabits northern Italy and western Slovenia, where it is considered close to extinction. All its populations across its entire range are in drastic decline. A preparatory study was performed in 2015-2016, following IUCN guidelines for reintroduction, with a multidisciplinary approach and including a genetic analysis of Italian (Ticino) stock compared with Slovenian specimens. The results of this study supported the reintroduction programme, including the release of Ticino specimens.

OBJECTIVES

The main objective of the LIFE for LASCA project is to conserve the extremely endangered fish species, South European nase (Protochondrostoma genei).

Specific project objectives include:

Ensuring the back-up of genetic material in the form of captive-bred South European nase, which serve as a source of specimens for its reinforcement in the wild;

Planning the species’ reintroduction to the Vipava river basin in order to improve the conservation status of the species in Slovenia;

Establishing a South European nase conservation management plan, which considers all threats to the species in the wild; and

Reducing numbers of the invasive fish species, Chondrostoma nasus, which competes with the South European nase for resources.

Thus, the objectives are strongly linked to Annex II of the Habitats Directive and the EU Regulation on invasive alien species.

Expected results:

Creation of South European nase stock in Slovenia, as a source of juveniles for reintroductions;

Release of at least 150 000 specimens into the Vipava river watercourses, expecting about 500 successfully released specimens by 2021;

Production of an action plan for South European nase conservation, and its verification and official adoption by competent authorities;

Numbers of the invasive fish species, Chondrostoma nasus, decreased by at least 60% in the Vipava river watercourse ; and

Young people’s and anglers’ awareness of the endangered fish species is raised significantly.
