We provide the first known comparative assessment of metazoan parasite communities in two taxonomically and ecologically related sparids, Boops boops and Spicara maena, that are common in the coastal infralittoral habitats in the Mediterranean. Using abundant data for infracommunities in three localities off the Algerian coasts of the Mediterranean, we tested the general prediction that the phylogenetic proximity of the two hosts, their overlapping geographical distribution and habitat occupation, as well as the similar feeding habits and diet would contribute to a homogenization of their parasite community composition and structure. The regional fauna of parasites of B. boops and S. maena along the Algerian coasts of the western Mediterranean was species-rich (36 species) and dominated by heteroxenous species (27 spp; of these 20 digenean spp.). The phylogenetic relatedness between the two hosts resulted in a large number of shared parasites (56 %, 20 spp.). However, the significant overlap in the parasite faunas of the two sparid hosts and their similar feeding habits and diet did not translate into homogeneous parasite community pattern; a significant differentiation in terms of both, composition and structure, was observed.

The present work was designed to assess the contamination level in the coastal of Annaba, following the spectrophotometric determination of the level of some metallic elements (Fe, Cu, Pb, Zn, Ni and Cd) in the sediments along an increasing bathymetric gradient (10 m and 20 m), as well as in the biological indicator grey mullet (Mugil cephalus) muscle. During the winter period (2014), 12 surface sediment samples, and a total of 24 fish were collected. Once the samples are dried, crushed and sieved, 0.5 g dry weight of each sample was added to concentrated acids. The results showed that the levels of some metals are superior to the recommended guideline values, and consequently the sediment of this bay is contaminated by iron, lead and copper. The contamination index (CI) showed a general tendency in the concentration of the studied metals as follows: Fe > Pb > Cu > Zn > Ni > Cd, since the most studied metals occurred at higher concentration in depth (20 m).
However, the average concentrations of metals in fishes were found to be as the following order: Fe > Zn > Pb > Cu > Ni > Cd. The consumption of fish from some contaminated sites can be dangerous because concentrations of lead, cadmium and zinc exceed the international standards. Moreover, the strong positive correlation observed between the metallic elements of sediments and fishes confirm that these metals resulted from the similar sources of the anthropic activities, such as domestic, port, industrial and agricultural waste discharges. This is confirmed by the determined of pollution load index (PLI) parameter. Conclusively, a regular monitoring program of heavy metal is recommended for protecting these organisms, and to reduce the environmental risks.

distinct periods may be identified: military planning (1830–1840), the birth of the European city (1840–1880), extramural expansion and urban growth (1880–1914), transformation between the two world wars and rural immmigration (1914–1945) and that of housing shortage and bidonvilles until 1962 ( Hadjri & Osmani 2004 : 30). In the early years after the capture of the most important cities on the Algeriancoast, the French did not interfere with their urban structure. Algiers was treated as a foothold for possible further expansion into the country. If the French made
