Trophic ecology of Mullets during their spring migration in a European salt marsh: A stable isotope study
Estuarine Coastal and Shelf Science, 2011Co-Authors: Benoit Lebreton, Pierre Richard, Emmanuel Parlier, Gaël Guillou, Gérard BlanchardAbstract:Mullet populations are abundant in littoral waters throughout the world and play a significant role in organic matter fluxes. Mullets are opportunistic feeders: adults have frequently been shown to feed on primary producers (e. g. fresh or detrital plant material, microphytobenthos) but they may also feed on meiofauna. The population structure and stomach contents of Mullets that colonize salt marsh creeks in Aiguillon Bay (French Atlantic coast) were studied to determine if they use salt marshes as a feeding ground in spring. Stable isotope analyses were carried out on Mullets sampled to assess their diet during their spring migration. The Mullet population was primarily composed of young-of-the-year (G0), 1-year old (G1) of both Liza ramada and Liza aurata species and 3-year-old or older (G3+) L. ramada individuals. G0 and G3+ population densities increased during the spring period: catch per unit effort (CPUE) increased from 0.22 to 1.49 ind.min-1 for the G0 age group; but stomach content analyses revealed that only G1 and G3+ feed in the salt marsh. Isotopic signatures of G1 (spring: δ13C: -14.8‰, δ15N: 14.1‰) and G3+ Mullets (spring: δ13C: -16.9‰, δ15N: 13.8‰) indicate that Mullet growth is supported largely by primary consumers, such as benthic meiofauna or small macrofauna. Mullets are thus positioned at a much higher trophic level than true primary consumers.

Ligophorus spp. (Monogenoidea: Dactylogyridae) parasitizing Mullets (Teleostei: Mugiliformes: Mugilidae) occurring in the fresh and brackish waters of the Shatt Al-Arab River and Estuary in southern Iraq, with the description of Ligoph
Parasitology Research, 2013Co-Authors: Delane C. Kritsky, Najim R. Khamees, Atheer H. AliAbstract:The gills of three of five species of Mullets (Teleostei: Mugiliformes: Mugilidae) collected from the brackish and fresh waters of southern Iraq were infected with species of Ligophorus (Monogenoidea: Dactylogyridae) as follows: greenback Mullet Chelon subviridis (Valenciennes) infected with Ligophorus lebedevi Dmitrieva, Gerasev, Gibson, Pronkina and Galli, 2012, Ligophorus bantingensis Soo and Lim, 2012, Ligophorus sagmarius n. sp., and Ligophorus fluviatilis (Bychowsky, 1949) Dmitrieva, Gerasev, Gibson, Pronkina, and Galli, 2012; Klunzinger’s Mullet Liza klunzingeri (Day) with L. bantingensis , L . fluviatilis , and an apparently undescribed species of Ligophorus ; and abu Mullet Liza abu (Heckel) with L. bantingensis and L . fluviatilis . The keeled Mullet Liza carinata (Valenciennes) and Speigler’s Mullet Valamugil speigleri (Bleeker) were uninfected. L. sagmarius n. sp. is described, and L. lebedevi and L. bantingensis are redescribed. Available specimens of L . fluviatilis and the undescribed species of Ligophorus from Klunzinger’s Mullet were insufficient for description.

Gyrodactylus aff. mugili Zhukov, 1970 (Monogenoidea: Gyro-dactylidae) from the gills of Mullets (Mugiliformes: Mugilidae) collected from the inland waters of southern Iraq, with an evalutation of previous records of Gyrodactylus spp. on Mullets in Ir
Folia parasitologica, 2013Co-Authors: Delane C. Kritsky, Atheer H. Ali, Najim R. KhameesAbstract:Abstract: Gyrodactylus aff. mugili Zhukov, 1970 (Monogenoidea: Gyrodactylidae) is recorded and described from the gill lamellae of 11 of 35 greenback Mullet, Chelon subviridis (Valenciennes) (minimum prevalence 31%), from the brackish waters of the Shatt Al-Arab Estuary in southern Iraq. The gyrodactylid was also found on the gill lamellae of one of eight Speigler's Mullet, Valamugil speigleri (Bleeker), from the brackish waters of the Shatt Al-Basrah Canal (minimum prevalence 13%). Fifteen Klunzinger's Mullet, Liza klunzingeri (Day), and 13 keeled Mullet, Liza carinata (Valenciennes), collected and examined from southern Iraqi waters, were apparently uninfected. The gyrodactylids from the greenback Mullet and Speigler's Mullet were considered to have affinity to G. mugili Zhukov, 1970, and along with G. mugili may represent members of a species complex occurring on Mullets in the Indo-Pacific Region. A single damaged gyrodactylid from the external surfaces of the abu Mullet, Liza abu (Heckel), was insufficient for species identification. Previously identified species of Gyrodactylus recorded on L. abu in Iraq by various authors were considered possible misidentifications or accidental infections.
