“…Environmental elements, such water salinity, temperature, the intensity of light and food supply have an impact on isopod numbers and spread (Dufour, 2007). In this study, the total prevalence of Livoneca redmanii in the sampled Pomadasys stridens was 48.75%.…”

The striped piggy, scientifically known as Pomadasys stridens (Forsskål, 1775), belongs to the Haemulid family and is one of its five members. This particular species of fish is relatively small in size and can be found in shallow waters. It feeds on shellfish and smaller fish species (Froese & Pauly, 2018). The spawning season of striped piggy is in spring and summer (Golani et al., 2006). The haemulid fish are scattered in the Mediterranean Sea through the Suez Canal (Bodilis et al., 2013) and are recorded in Attaka in the Gulf of Suez (Osman et al., 2019).Mixed infections often occur when multiple pathogens, such as bacteria, parasites, viruses or fungi, infect the same fish, simultaneously resulting in a secondary concurrent infection. These types of infections can have detrimental effects on fish, amplifying the

“…Isopod abundance and dispersion are influenced by environmental factors such as water temperature, salinity, light intensity, predators, and food availability [ 46 ]. The total prevalence of L. redmanii in sampled D. labrax was 23% over the year, with the highest significant prevalence in the summer and the spring, and the lowest significant prevalence in the winter.…”

Background Prevalence, morphology, and molecular characteristics of isopodiosis in the European seabass, Dicentrarchus labrax, in Egypt were assessed using light and electron microscopy and polymerase chain reaction targeting the mitochondrial COI (cytochrome oxidase c) gene. Results Adult parasites were found mainly in the branchial cavity between gill arches and to a lesser extent in the buccal cavity. They were morphologically identified as the Cymothoidae Livoneca redmanii Leach, 1818 (Crustacea: Isopoda). Obviously, a 23% prevalence rate of isopods was reported in D. labrax from Egyptian Mediterranean waters. Destructive and degenerative necrotic alterations with complete sloughing of gill lamellae of the infested fish were observed. DNA sequencing of the mitochondrial COI gene confirmed the identification of the parasite which was deposited in the GenBank under accession numbers MW600099, MZ208984, and MZ208985. Furthermore, the phylogenetic analysis demonstrated that parasites emerged from a monophyletic clade closely affiliated with L. redmanii and were clearly distinguished from other isopod genospecies. Conclusion The present investigation addresses L. redmanii infestation in D. labrax in Egypt and affirmed morphological properties via the scanning electron microscopy (SEM) and molecular characteristics of this isopod species. The drastic effects of this parasite on the infected fish were proven both clinically and histopathologically.

“…temperature, salinity, nutrients) causing the change and distribution in algae and seagrass cover on which animals live (Arrontes & Anadón 1990). There are several potential environmental factors that might influence a species' distribution and abundance, including water temperature, salinity, light level, shelter from predators, and food resources (Dufour et al 2007). Based on the recorded temporal distribution of Idotea and temperature and salinity fluctuations, we found that I. b. basteri, with a marine tendency, occurs at higher temperature and salinity than lagoonal species I. c. mediterranea, and contrary to Sphaeromatidea distribution.…”

The distribution of four isopods-Idotea balthica basteri (Pallas, 1772), Idotea chelipes mediterranea Charfi-Cheikhrouha, 1996, Sphaeroma serratum (Fabricius, 1787), and Paracerceis sculpta (Holmes, 1904)at Menzel Jemil (Bizerte Lagoon, North Tunisia) was analysed and then related to the variation of temperature, depth and plant biomass. The abundance of isopods showed monthly fluctuations with maxima in August and minima in December 2010. The most dominant species was I. b. basteri followed by S. serratum, with a spatial gradient in the distribution pattern of isopod species in the study area. The high density of juveniles in algae and seagrass highlights the important role played by this habitat as a nursery for species. Both dominant species were tolerant to temperature variations, with some preference values (19.73-27.73°C in I. b. basteri; up to 28°C in S. serratum) and salinity (36.7-38.6 psu in I. b. basteri; 39-39.2 psu in S. serratum). Multiple regression analysis between environmental variables and species abundance showed a positive relationship with biomass of Gracilaria bursa-pastoris and Ulva lactuca for the two species of Idotea and Sphaeroma, respectively, while abundance of P. sculpta was positively related to temperature. Biotic and environmental linking (BIOENV) analysis confirmed the greatest influence of temperature and vegetation biomass on the temporal distribution of these isopod species. A spatial distribution pattern according to successive depths was revealed.
