However, their ecological characteristics are totally different. The lake Vistonis receives higher amounts of fresh water and pollution than the lake Lagos. These environmental sensitive wetlands traditionally constitute areas for semi-extensive aquaculture that is a key factor within local economy structure. Grey mullets (fam. Mugilidae), sea bass and sea bream, are the dominant fish species in the fishery production of both of lakes but the lake Vistonis production also includes carps and eels. Detail fishery production data were collected from local fishery co-operatives that manage both ecosystems and Fishery Direction for the last decades (1974 - 2004) concerning the total production and the dominant fish species separately for each lake ecosystem.

Aquaculture constitutes the major economic type of the exploitation of these coastal wetlands that faces favourable challenges, well adapted with their sensitive environment. Necessary data to implement the multimedia learning system were retrieved from scientific references and research programs. The collected material in type of texts, drawings, pictures and videos are digitised and then integrated in the multimedia project. The software used for the creation of the multimedia learning CD-Rom was Macromedia Studio MX 2004, PhotoShop 6.0, Fine Reader V.5 and Nero 7.2.
