*3.5. Mălâncrav River*

Based on the field inventory on the Mălâncrav River, only three refuge habitats were identified with a depth of 100–110 cm (i.e., Figure 11); the other non-refuge sectors (i.e., Figure 12) had different depths between 10 and 100 cm.

In the Mălâncrav River, four fish species have permanent populations: *Squalius cephalus* (Linnaeus 1758) (total caught individuals 12), *Gobio gobio* (Linnaeus, 1758) (8), *Barbus meridionalis* Risso 1827 (22), and *Barbatula barbatula* (Linnaeus 1758) (13).

The ratio between the number of fish between the refuge habitats of maximum 10 m in length and the adjacent/downstream non-refuge sectors of 500 m length was four to one.

Refuge habitats are rarely present throughout the length of the river, but should be more numerous, with at least one every 500 m.

Given the general depth of the Mălâncrav River and the vulnerabilities that occur for fish during periods of drought, the building of artificial refuges for fish from about 500 to 500 m is proposed. In total, it would be necessary to build a number of 21 such refuges with a depth of at least one meter (Scheme 5).
