PREvent, Detect and combAT the spread Of SiluRus glanis in south european lakes to protect biodiversity

Introduction

LIFE PREDATOR aims at contrasting the spread and further introductions of the invasive European catfish Silurus glanis, contributing to the application of the EU IAS Regulation n. 1143/2014 in southern European lakes.

Early Detection System

An early detection system based on environmental DNA will be tested and developed in 50 lakes:

• 23 in Italy
• 25 in Portugal
• 2 in the Czech Republic

This system will be integrated with citizen science records.

Capture Methodologies

In 10 selected lakes where the species is widespread and abundant, different capture methodologies will be tested to select the best selective and effective capture method. The goal is to reduce the catfish biomass by:

1. 90% in 5 small and isolated Natura 2000 lakes
2. At least 10% in large lakes and reservoirs
3. 50% in small reservoirs

These activities will involve at least 130 commercial fishermen and 100 anglers.

Awareness-Raising Campaigns

Massive awareness-raising campaigns are organized targeting specifically anglers (at least 400,000) but also the general public. The project expects to reach 1 million people by the end of the project, including 12,000 school children.

Protocols and Best Practices

Protocols and best practices will be transferred to at least 15 management authorities to be integrated into their management plans, particularly of Natura 2000 sites.

Replication of Results

For the replication of the project results, a South European Catfish Management Group (SEMG) will be created.

Local Circular Economy

Additionally, to sustain the project goals where the catfish invasion is more advanced (i.e., northern Italy), the creation of a local circular economy is proposed. This initiative seeks the best solution to make the catfish more palatable, thereby increasing the fishing pressure on catfish by encouraging its consumption as food.

Social Impact

The catfish removed during control campaigns will be used for the preparation of meals sold at fair prices by social cooperatives to at least 1,000 people facing socio-economic challenges.
