    Résumé

    A single specimen (219.6 mm in standard length) of East Asian fourfinger threadfin (Perciformes: Polynemidae), Eleutheronema rhadinum (Jordan & Evermann, 1902), was captured with gillnet in Yangtze River estuary near Yangzhong County, Zhenjiang, China, on 30 October 2018. It is the first record of E. rhadinum in freshwaters of the Yangtze River Estuary.

    Résumé

    The diet of the black scorpionfish Scorpaena porcus (Linnaeus, 1758) of Annaba Gulf (Eastern Algeria) was studied from April 2011 to April 2012. A total of 520 specimens, with a total length between 10.2 and 27.8 cm, were analyzed. Analysis of the digestive contents revealed a dominance of decapods crustaceans (%IRI = 91.2). This species ingested an average of 0.58 prey weighing 0.73 g. For both sexes, arthropods were essential prey (%IRIm = 73.6; %IRIf = 86.9). The diet of large (L) individuals was mainly divided between arthropods (%IRIL = 56.3) and teleosts (%IRIL = 34). Small (S) and medium-sized (M) black scorpionfish mainly focused on arthropods (%IRIS = 98.3; %IRIM = 86.5). The average annual digestive vacuity was of 40.8% and varied significantly according to seasons. There was no significant seasonal change in diet except in the summer.

    Résumé

    This study described a new stone loach species in France, Barbatula leoparda, which is endemic to French Catalonia (Têt and Tech river drainages). Seven specimens were compared to 49 specimens of B. barbatula (Linnaeus, 1758) and 71 specimens of B. quignardi (Băcescu-Meşter, 1967). This new species is characterized by the presence of blotches on the belly and the jugular area in individuals longer than 47 mm SL and by a greater interorbital distance (35.5 to 41.8% of the head length). We brought moreover the sequence of two mitochondrial markers (COI and 12S, respectively 652 and 950 bp) of the holotype, which are well distinct from all other species, for molecular identifications. This discovery is important for conservation.

    Résumé

    A molecular identification via DNA barcoding (COI marker, 651 bp) was done on a minnow caught in the Rupt de Mad stream at Essey-et-Maizerais (Rhine/Moselle catchment). Accordingly, the specimen belongs to the recently revalidated Phoxinus csikii Hankó, 1922. It is the first record of this species in France, and the fourth minnow species known in this country.

    Résumé

    Abstract

    The fishes collected during the Biaçores research expedition on board R/V Jean Charcot, in October/November, 1971, were studied and a list of stations given. In all, 861 specimens, belonging to 98 species and 48 families from 79 stations, seven of which in the high seas and 72 around or on the coast of the islands of the Azores, were identified. The presence of Rajella bathyphila (Holt & Byrne, 1908) and Arnoglossus imperialis (Rafinesque, 1810) is here confirmed.
