Iberochondrostoma Lusitanicum
📖 Overview
Found in coastal rivers and terminal segments of main rivers . Adults occur in middle and lower reaches of streams, with slow current and underwater vegetation. They form large spawning aggregations . Threatened due to habitat destruction . Migration pattern is inferred from the behavior of other species in the same genus .
🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 3; Dorsal soft rays (total): 6 - 8; Anal spines: 3; Anal soft rays: 6 - 8. Diagnosis: Lateral line scales (43)45-49(51); above lateral line (9.5)10-11(10.5); right pharyngeal teeth 5-6 . Differs from its congeners by having eye diameter greater than snout length, usually 43-47 + 2-3 scales on lateral line and 3½-5 scale rows between lateral line and pelvic origin .

🦐 Diet
🥚 Reproduction
Forms large spawning aggregations. A female spawns with one or a few males, which press the female against the substratum and eggs are released. These movements attract other individuals to start spawning. The aggregations disperse after about 20-60 seconds and many form again several times. Deposits adhesive eggs .
🌍 Habitat & Distribution
Freshwater; benthopelagic; potamodromous . Subtropical; 43°N - 37°N, 9°W - 6°W south bank tributaries of Tagus.

🎣 Angling Guide
- medium-heavy 7ft spinning rod
- 30-50 lb braid
- fluorocarbon leader
- grass flats
- oyster bars
- marsh drains
- deeper channel edges
Use barbless hooks, minimise air exposure, and revive fish head-first in current before release.
⚠️ Slot limits protect breeding-size fish. Verify daily bag limits.
