This study aimed to analyse the quality of the sea water flowing into the marine farm of Douhet, a gilthead bream hatchery, from the marsh-seawater reservoir to the entrance of the hatchery. The basin-seawater reservoir is not stratified in the pumping area. As a consequence, the measurements carried out at the surface to the right of the pumping dock give a good evaluation of the quality of the seawater pumped in depth. The high sensitivity of gilthead bream larvae to the water PH during the first two weeks of their larval life, and the values measured in the circuit seem to be an explanatory parameter to the observed mortalities. The water flowing into the hatchery retains, after pre-treatment, a nycthemeral PH variability, with maxima, at the end of the...

This study describes my work within the AMBIO project at the IFREMER center of Noumea. The aim of this study is to analyze and to treat underwater video to make a short ecological report of Koné lagoon. After an explanation of the video technics used (STAVIRO) and of the pictures analyze protocols, you will find a description of the working area. Next, this report presents ecological status of this place.
