SYMPHODUS (CRENILABR US) OCELLA TUS BERTINI (PRAS, 1961) (PISCES, 
LABRIDAE), A N E W  RECORD FOR THE SPANISH M E D I T E R R A N E A N  
COAST 
The Red Wrasse Symphodus (Crenilabrus) 
ocellatus bertini (Pras, 1961) is an endemic 
subspecies of the Mediterranean Sea (FREDJ 
& MAURIN, 1987). It lives on rocky bottoms 
and near eel-grass beds up to 30m of depth 
(QUIGNARD & PRAS, 1986). It is found mixed 
with other Labridae, specially Symphodus 
(Crenilabrus) ocellatus ocellatus (Forsskal, 
1775), among which it appears in arate of not 
more than 0.1% (Pras in GARNAUD, 1970). 
The subspecies was discovered for the 
first time in Salins d'Hykres (PRAS, 1961), 
near Toulon (France), in the eastern end of 
the Gulf of Lion. Found in 1963 and 1964 by 
the Zoological Station from Villefranche-sur-

Mer (GARNAUD, 1970), it has been seen re- 
cently in Le Brusc, near Sanary (France), 
(PRAS, 1982) and south of Sicily (FREDJ & 
MAURIN, 1987). 
During 117 scuba diving carried out 
between January 1986 and February 1990 in 
the littoral of Palamós (Costa Brava, NE 
Spain), S. (Cr.) ocellatus bertini was seen ten 
times, mainly in summer, swimming alone on 
rocky bottoms or on Posidonia oceanica mea- 
dows among many specimens of S. (Cr.) oce- 
llatus ocellatus. 
The only specimen of the red wrasse stu- 
died was a male of 60.6 mm TL. It was caught 
together with four specimens of S. (Cr.) oce-

llatus ocellatus -two males and two females- 
with a fishing hand net on 12 VI11 1987 at 6 m 
depth in Torre Valentina (41" 49' 55" N- 
3 O  05' 20nE), in the western end of the Bay of 
Palamós (fig. 1). 
Body and fins show an orange-red colour. 
It has a black spot like an ocellus on the rear 
corner of the operculum and a small one on 
the caudal peduncle, below the lateral line 
(fig. 2). These remarks agree with the ones of 
PRAS (1961) and GARNAUD (1970). 
The specimen from Palamós has the ce- 
phalic and preorbital lengths bigger that 
those from the French coast studied by PRAS 
(1961) and GARNAUD (1970) (table 1). In re- 
gard to meristic characters, the specimen 
from Palamós has 11 soft dorsal finrays while 
the others show nine or ten. PRAS (1961) 
counts six soft pelvic finrays in his specimen 
while there are only five in the rest. 
It would be interesting to compare the 
biometric and meristic characters from both 
sexes but, at present, any female of S. (Cr.) 
ocellatus bertini has been caught. The paper 
of PRAS (1982) suggests several hypothesis to 
explain the absence of the females. 
Both opercular and caudal peduncular 
dark spots of S. (Cr.) ocellatus bertini are si- 
milar to the S. (Cr.) ocellatus ocellatus caught 
in Palamós, but smaller. Both subspecies dif- 
fer on its colour and specially on the eye dia- 
meter and caudal fin length, bigger in the form- 
er (table 2). It can also be seen that the dor- 
sal and anal fins of S. (Cr.) ocellatus ocellatus 
from Palamós has one or two soft rays less 
than the ones of S. (Cr.) ocellatus bertini. The 
contrary occurs with the pectoral fins. 
This record is then the first one in the Spa- 
nish Mediterranean coast and it increases the 
reduced geographical distnbution of Sym- 
phodus (Crenilabrus) ocellatus bertini.

Symphodus (Crenilabrus) ocellatus bertini (Pras, 
1961) (Pisces, Labridae), a new record for the Spanish 
Mediterranean coast.- The capture of one specimen o€ 
the red wrasse (Symphodus (Crenilabrus) ocellatus 
bertini (Pras, 1961)) in the littoral o€ Palamós (Costa 
Brava, NE Spain) is reported. Its biometric and me- 
ristic characters are compared with those of several 
specimens caught in the French Mediterranean coast.

RESUMEN 
Symphodus (Crenilabrus) ocellatus bertini (Pras, 
1961) (Pisces, Labridae), nueva especie para la costa 
mediterránea española.

jado (Symphodus (Crenilabrus) ocellatus bertini

DATOS SOBRE LA ALIMENTACIÓN DE ARDÉIDOS EN EL DELTA 
DEL EBRO 
La alimentación de los ardéidos se conoce re- 
lativamente bien (MOLTONI, 1936, 1948; 
SIEGFRIED, 1971; OWEN & PHILLIPS, 1956; 
WILLIAMS, 1959; HAFNER, 1977; HOFFMAN, 
1978; FASOLA et al., 1981). Sin embargo, en 
el caso del Delta del Ebro, únicamente se dis- 
pone de información de alimentación durante 
un ciclo anual para la garcilla bueyera (Bu- 
bulcus ibis) (Rurz, 1985), mientras que en el 
resto de especies, fuera del período reproduc- 
tor se desconoce. Por ello se ha considerado 
de interés la publicación de los contenidos 
gástricos de nueve ardéidos adultos proce- 
dentes del Delta del Ebro: cuatro garzas rea- 
les (Ardea cinerea) y un martinete (Nyctico- 
rax nycticorax) capturados en enero de 1978 y 
cuatro garcetas comunes (Egretta garzetta) 
capturadas en abril de 1980. 
Hasta el momento de su análisis, los estó- 
magos se conservaron en alcohol de 70°. Pos- 
teriormente se disgregó el material mediante 
un tamizado y se procedió a la identificación
