“…Large numbers of gray mullet species and other euryhaline species could positively influence the ecology of the lagoon by limiting the aquatic algal cover and influence the detritus that now accumulates and increases eutrophic conditions leading to the increase in dead organic matter in the lake. Gray mullets have even been used as biological controls of algae in reservoirs (Leventer 1981) since they normally feed on benthic and planktonic algae and detritus (Cardona and Castello 1994;Cardona et al 2001). The consequences of this biological element in restoration will enhance a more natural functioning of the lagoon, yet it should not be considered a biological control mechanism.…”

Integrated ecological assessment and restoration planning in a heavily modified peri-urban Mediterranean lagoon

An integrated ecological assessment and restoration plan has been developed for Koumoundourou Lake, a heavily modified peri-urban lagoon near Athens, Greece. After the construction of an artificial weir on the coastal lagoon's canal outlet with Elefsina Bay, the water quality has improved and a short-term decrease in heavy metal concentrations in sediments is noted, which indicates a slow amelioration during the last decade. Nevertheless, the weir construction since the mid-1990s has changed the hydrological conditions of the wetland; it inevitably blocked marine fish movement and extirpated several fish species, while the area occupied by submerged aquatic vegetation has expanded due to the reduction in the lagoon water's salinity. In order to maintain the improved water quality and ecological potential of Koumoundourou Lake, the construction of a fish pass within the sluice is recommended that would allow the free passage of fishes (particularly gray mullet mugilidae). Although this is expected to affect the current hydraulic conditions of the lagoon and may increase the salinity and slightly decrease the time renewal of the water, the lagoon's ecological potential is expected to improve as the food web will be enriched.

ABSTRACT1. During a study of five artificial brackish ponds situated in Don˜ana Natural Park and the Guadalquivir delta between July 2001 and June 2002, a total of six copepod species (two calanoids, three cyclopoids and one harpacticoid) were recorded. All of them are typical of brackish or estuarine habitats.2. The estuarine calanoid copepod Acartia tonsa (originally from North America) was present in all the ponds studied. This exotic species has been found previously in European estuaries, but has not previously been recorded from artificial wetlands.3. Both the relative and absolute abundance of the species varied significantly among months and ponds. A. tonsa was most abundant during autumn and spring, while Calanipeda aquae-dulcis was most abundant in summer. This seasonal pattern of the copepod community composition was different from that reported in studies from other European estuaries or wetlands.4. The invasion by and dominance of A. tonsa in the area of Don˜ana Natural Park has important implications for the conservation of the diverse native zooplankton fauna in the natural marshes of the adjacent Don˜ana National Park, which includes endemic species.
