Etymology: Liza: Spanish, liza = grey mullet.
Environment / Climate / Range
Marine; freshwater; brackish; pelagic-neritic; catadromous (Ref. 51243); depth range 10 - ? m (Ref. 7399). Temperate; 64°N - 20°N, 26°W - 42°E
Length at first maturity / Size / Weight / Age
Maturity: Lm 34.0  range ? - ? cm
Max length : 59.0 cm TL male/unsexed; (Ref. 2058); common length : 30.0 cm SL male/unsexed; (Ref. 7399)
Eastern Atlantic: Scotland to Cape Verde; in the Mediterranean and Black Sea. Also in coastal waters from southern Norway to Morocco, rare off Mauritania (Ref. 3573). Records from the lagoon of Accra are probably misidentifications.
Neritic, entering lagoons and lower estuaries (Ref. 7399); rarely entering fresh water (Ref. 3573, 59043). Feed on small benthic organisms, detritus, and occasionally on insects and plankton (Ref. 2804). Reproduction takes place in the sea, from July to November. Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Minimum size allowed for fishing is 20 cm. The quality of the flesh is variable (Ref. 30578).

Bayesian length-weight: a=0.00977 (0.00767 - 0.01244), b=2.97 (2.93 - 3.01), based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 2.5 ±0.2 se; Based on diet studies.
Resilience (Ref. 69278
