Since its establishment in 2010, the Mayotte Marine Natural Park has been promoting fishing activities beyond the lagoon, specifically targeting pelagic species to alleviate fishing pressure on reef species. However, despite these efforts, catches of reef fish remain notably high. In 2020, reef carnivores (groupers, snappers…), constituted approximately 35% of the total catches. Ensuring the sustainability of reef fishing necessitates regular assessments of Mayotte's commercial reef fish populations. This study aims to evaluate the current status of these populations and comprehend their dynamics by comparing them with historical data. Scuba diving was employed for the assessment of ichthyological populations and habitat description. In 2023, a total of 96 sites, comprising 1,100 stations (Stationary visual census), were sampled, covering a combined sampled area of 169,400 m2, with an in situ observation duration totalling 110 hours.

This dataset contains an inventory of the benthic fauna of the Tunisian coasts by bottom trawling and dredging. The objectives are not known. We assume that this is an exploratory seabed trawling survey to assess the fishing possibilities in the region with this gear. We know that the inventory was written by Jacques Ancellin (director of the Boulogne-sur-Mer laboratory after the Second World War and he joined the OSTPM in 1942). Only species presence were recorded. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

The dataset represents data primary processing of zoobenthos samples taken in the Chaun Bay of the East Siberian Sea in October 2020 during an expedition onboard R/V "Akademik Oparin" Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

This dataset includes all the CHALIST surveys between 1983 and 1992, that is five surveys undertaken in 1983, 1985, 1986, 1987 and 1992. The aim of CHALIST surveys was to evalute the demersal resources of the Gulf of Lion in order to monitor annual variations of the main commercial species in terme of spatial distribution, average weight and size and age compositions and abundance indices. All the target species collected were identified, weighted and counted. Length measurements were also carried out for a number of species.

Alien species from a field observation

This dataset contains nifH gene copy numbers, growth rates, and grazing mortality rates of the major unicellular cyanobacterial diazotroph taxa (UCYN-A1, -A2/3/4, -B and -C), and growth rates and grazing mortality rates of total phytoplankton community (inferred by chlorophyll a) in the South China Sea and the Luzon Strait. The associated physicochemical factors including temperature, salinity, nitrate+nitrite, ammonium, phosphate, and chlorophyll a are also available in this dataset. All these data were collected during a research cruise (Cruise No. kk1801) aboard the R/V Tan Kah Kee in early February 2018.

The dataset contains the results of the monitoring activity in distinct years in Slovenian coastal waters related to contaminants in Sea water, sediments and biota.
