    Observation on distribution, biology, growth, diet and feeding strategy of blackmouth catshark Galeus melastomus (Rafinesque, 1810) (Chondrichthyes: Scyliorhinidae) in western Algerian coasts
    https://doi.org/10.31396/Biodiv.Jour.2018.9.4.357.368

    ABSTRACT
    The blackmouth catshark Galeus melastomus (Rafinesque, 1810) (Chondrichthyes Scyliorhinidae) is an accidentally caught species and it acts as a sentinel, by reflecting the state of the region’s fish stocks. Its vulnerability to the impact of fishing, along with the low fertility and late reproduction, do not ensure a good renewal. Data, collected during 13 months from November 2015 to November 2016, were analysed to enrich our knowledge on the population, reproductive biology, growth, and feeding strategy of the blackmouth catshark from the Western coast of Algeria. A total of 551 specimens, 360 males and 191 females, were caught. Their size ranged from 25 cm to 56 cm for both sexes. The length of the first sexual maturity was stunted at 54 cm in females. The asymptotic length was deduced from the von Bertalanffy growth equation to be higher for males than females (females: L∞ = 51.79 cm; males L∞ = 52.14 cm) and the study of the height-weight relationship revealed allometric growth. 551 stomachs were examined and the vacuity index was found to be 63.75%. The preys identified belonged primarily to three major groups: Crustaceans, Osteichthyes, and Cephalopods. Our results show that the feeding strategy of G. melastomus is to be considered generalist and differs from one month to another.

    Reproductive biology and growth of Lesser Spotted Dogfish Scyliorhinus canicula (Linnaeus, 1758) in Western Algerian coasts (Chondrichthyes, Scyliorhinidae)

    ABSTRACT
    Elasmobranch fishes have a large distribution. At the level of the Mediterranean fisheries, a low density of elasmobranchs is noted at the assemblages, these fisheries appearing near to the point of best efficiency or even to over-exploitation. Indeed, a general decline of shark populations was observed over the last decade on the Mediterranean coast. The aim of this work was to evaluate different biological characteristics of the species Scyliorhinus canicula (Linnaeus, 1758). A sampling of 461 specimens was realized between September 2009 and August 2010 from the western coast of Algeria. The oviduco-somatic index OSI, the hepatosomatic index (HSI) and the condition factor (Kn) were estimated monthly for 249 females to identify the reproduction period. Obtained results show a rapid maturation from September to November and from February to April when the Kn values are very low.

    Coastal dune vegetation: dynamic and influence of anthropogenic factors
    https://doi.org/10.31396/Biodiv.Jour.2021.12.3.655.662

    ABSTRACT
    This study describes the vegetation dune systems status in relation to antroipogenic disturbance factors in the coastal stretch of the Madrague area in Algeria. This study was carried out during the spring and summer of 2018. Particular emphasis was given to flora composition by assessing their frequency and diversity. Vegetation sampling was carried out along twenty shore-perpendicular transects recording different data. The flora inventoried highlights a strong dominance of the Asteraceae family, which accounts for 24.32% of all inventoried species. Analysis of the biological spectrum shows the predominance of therophytes, with rate of 32.43%, indicating an average degradation whose origin is anthropogenic action. The IP disturbance index of our study area is about 51 %, it confirms a moderately strong degradation of the natural environment. Biogeographically, the vegetation of the study area is constituted by a heterogeneous set of elements of various origins dominated by the Mediterranean element. From the cartographic point of view, the study of satellite photos enabled us to confirm the degradation of the plant revetment by comparing the areas covered between 2003 and 2018. A notable diminution of this is reported, due to the man activity and his herds.

    Reproduction and growth of Axillary seabream Pagellus acarne (Risso, 1827) (Perciformes Sparidae) from the Western Algerian coasts
    https://doi.org/10.31396/Biodiv.Jour.2020.11.2.351.358

    ABSTRACT
    Pagellus acarne (Risso, 1827) (Perciformes Sparidae) represents an important component of Algerian fishery catch. Reproduction and growth parameter of this species are studied during 13 months, from fish catched from western Algerian coasts from December 2015 to December 2016. The sex-ratio (F:M) of the population studied is 1:1.56 and is in favor of male. The reproductive season extends between late spring and autumn. The resting period occurs in winter. Length at first maturity is estimated at 18.63 cm and 16.95 cm for females and males respectively. The length-weight relationship obtained is TW=0.009TL3.086 (R²=0.983). The Von Bertalanffy growth equation parameters are K=0.41, L∞=29.97, t0 =-0.34 and the Φ’=2.57.

    Morphometric data and allometric relationships of the gorgonian Eunicella singularis (Esper, 1791) (Anthozoa Gorgoniidae) of Paloma Island, Algeria
    https://doi.org/10.31396/Biodiv.Jour.2019.10.3.185.194

    ABSTRACT
    The gorgonian Eunicella singularis (Esper, 1791) (Anthozoa Gorgoniidae) is abundant on rocky bottoms at Paloma Island (Algeria) in the south-western of the Mediterranean basin. In this study area, 150 gorgonian colonies of E. singularis were collected randomly using SCUBA diving and the following morphometric macro-features were measured (maximum height, maximum width, total branch length, rectangular surface area, height to width ratio and dry weight). Allometric growth was examined using the relationships between the dry weight and the five morphometric macro-features. The power equation of the simple allometry applied was y=axb and the parameters of the linear regression a and b were estimated after the logarithmic transformation log (y)=log( a)+ b*log(x). The allometric relationships between the dry weight and the morphometric macro-features studied show that the growth of the gorgonian E. singularis in the study area is correlated positively and significantly with the five macro-features and that both the macro-features total branch length and the maximum width are the most appropriate parameter applied to the gorgonian E. singularis growth study.

    Digenean parasites in two congeneric sparid fish and of commercial importance, Pagellus erythrinus (Linnaeus, 1758) and Pagellus acarne (Risso, 1827), from the western Mediterranean coast of Algeria
    https://doi.org/10.31396/Biodiv.Jour.2019.10.2.151.158

    ABSTRACT
    The investigation into the digenean fauna of two congeneric sparid fishes (Perciformes Sparidae), Pagellus erythrinus (Linnaeus, 1758) and Pagellus acarne (Risso, 1827), was carried out in the Algerian coasts (Western Mediterranean). These fishes of commercial importance represent an important biological resource for the human population along the Mediterranean coasts. However, the data on their digenean parasites in Algeria are incomplete and the aim of this study is to provide new data on the diversity and species composition of digeneans from these hosts. A total of 240 fishs (120 of each species) were collected from Oran (North-western Algeria) during 12 months between September 2016 and August 2017. Eleven species of digeneans were found in the two fish hosts: (i) Lepocreadium pegorchis (Lepocreadiidae); Lepocreadium album (Lepocreadiidae); Holorchis pychnoporus (Lepocreadiidae); Holorchis spp (Lepocreadiidae); Hemiurus comminus (Hemiuridae); Hemiurus luehei (Hemiuridae); Lepidauchen stenostoma (Acanthocolpidae) and Pachycreadium carnosum (Opecoelidae); Macvicaria crassigula (Opecoelidae) in Pagellus erythrinus; (ii) Lepocreadium pegorchis (Lepocreadiidae); Macvicaria crassigula (Opecoelidae); Zoogonus spp (Zoogonidae) and Hemiurus communis (Hemiuridae) in Pagellus acarne. In the evaluation of the dynamics of the epidemiological index of the community of digenean parasites, two species of fish show seasonal variations. Furthermore, higher prevalence of infestation were registered during the summer season for the Opecaelidae family in the two hosts.
