AbstractHypocreadium caputvadum sp. nov. (Digenea, Lepocreadiidae) is described from the intestine of Balistes capriscus Gmelin collected from the Gulf of Gabès (Tunisia) in the southern Mediterranean Sea. This new species can be distinguished by a combination of characteristics shared by no other described species of Hypocreadium Ozaki, 1936. These characteristics include the presence of a distinct anterior notch, the follicular vitellarium confluent in the forebody, the presence of a muscular sphincter at the level of the anterior third of the metraterm and the size and the position of the cirrus-sac.

AbstractAllopodocotyle tunisiensis sp. nov. is described from the intestine of Solea aegyptiaca Chabanaud collected from the Gulf of Gabès in the Mediterranean Sea off Tunisia. The new species belongs to the group C of Allopodocotyle Pritchard, 1966 species (sensu Bray 1987). It differs from its congeners in this group by the shape of the seminal vesicle and the anterior extend of the vitellarium which varies between just posterior to the ventral sucker and anterior margin. A key to the Allopodocotyle species of group C is presented. The status of the genera Allopodocotyle and Macvicaria (Gibson and Bray 1982) are briefly discussed.

AbstractLamellodiscus crampus sp. nov. (Monogenea, Diplectanidae) is described from the gills of Dentex maroccanus (Valenciennes) collected from the Gulf of Gabès (Tunisia) in the oriental part of Mediterranean Sea. The new species belongs to the “ignoratus” group (sensu Oliver 1987) characterized by a lamellodisc with complete lamellae and a “lyre” shaped male copulatory organ, and the “ignoratus” sensu stricto subgroup, characterized by a haptor with simple lateral dorsal bars, as proposed by Amine and Euzet (2005). Lamellodiscus crampus can be easily distinguished from all the congeneric species of the subgroup “ignoratus” by the presence, in the “lyre” male copulatory organ, of five spines in the distal portion on the axial side of the paired piece.

The age and growth parameters of grey triggerfish, Balistes capriscus from the Gulf of Gabès, southern Tunisia, Mediterranean Sea, were estimated from the first dorsal spine sections of 463 specimens (206 males and 257 females), whose fork length was between 139 and 427 mm and the total weight ranged from 90.04 to 1967.41 g. The monthly percentage of specimens having a terminal translucent zone has indicated that the growth zone is formed once a year, during the cold season (February). The von Bertalanffy growth equations were: FL = 420.7 [1 − e−0.233(t + 0.123)] and FL = 417.0 [1 − e−0.238(t + 0.074)], for males and females, respectively. The longevity estimated was 13 years old for both sexes. The instantaneous mortality rates were estimated to 0.23 for males and 0.24 for females. The weight–length relationships of the grey triggerfish were Wt = 21.510−3 LF3.046 and Wt = 41.010−3 LF2.835, for males and females, respectively.
