| The dystrophic crisis in the lagoon of Salses-Leucae in 1979-1980 resulted in a bloom of the chlorophyceae Nannochloris sp. which attained a density in the order of 10 super(9) cells/litre. The worst effect was the destruction of oyster and mussel cultures because of overfeeding. This bloom also caused high turbidity which induced the destruction of large parts of sea-grass communities (Zostera)). One year after the beginning of this crisis, a gradual improvement of ecological conditions was noted, especially in the pelagic zone. The benthic environment recovered at a much slower rate. Sea-grass showed signs of recovery, organic matter concentrations and bacterial populations decreased. Furthermore, the macrofauna density increased notably. Nevertheless,... |
