Reconstructing individual food and growth histories from biogenic carbonates

Environmental conditions experienced by aquatic organisms are archived in biogenic carbonates such as fish otoliths, bivalve shells and coral skeletons. These calcified structures present an accretionary growth and variations in optical properties - ...

Géodiversité sous-marine de la Nouvelle-Calédonie. 2ème partie

This article of the number 10 of Tai Kona is the natural complement to the article appeared under the number 8, dedicated to the submarine geodiversity of the New Caledonian EEZ. The first article notably put the bases of knowledge on the history, th...

This report synthesizes the discussions of a workshop organized during the "Liteau II-AMP" project , a collaborative project involving scientists and MPA managers that aimed at developing diagnostic and exploratory tools for the assessment of Marine ...

Crustal structure of the basin and ridge system west of New Caledonia (southwest Pacific) from wide-angle and reflection seismic data.

[1] During the Zoneco 11 marine geophysical survey (September 2004), two deep reflection seismic profiles recorded by ocean bottom seismometers were acquired in the offshore domain west of New Caledonia. The northern profile crosses the New Caledonia...

Grow-out of sandfish Holothuria scabra in ponds shows that co-culture with shrimp Litopenaeus stylirostris is not viable

We examined the potential for producing the large numbers of sandfish (Holothuria scabra) needed for restocking programmes by co-culturing juveniles with the shrimp Litopenaeus stylirostris in earthen ponds. Our experiments in hapas within shrimp pon...

Study of nutritional requirements and growth of penaeus merguiensis in tanks by means of purified and artificial diets

One of the criteria for selecting a shrimp of commercial interest in French Polynesia is the acceptability of artificial diet; such a criterion has been used to test Penaeus merguiensis.Experiments have been carried out in Centre Océanologique du Pa...

Croissance et Société bleues : quels intérêts et perspectives pour la Nouvelle-Calédonie

This article calls back first of all a set of facts relative to the main stakes considering sea and ocean so much on the economic point of view, in the scientific technological and innovative fields, in the governance aspects as also in the culture a...

Combined effect of temperature and salinity on osmoregulation of juvenile and subadult Penaeus stylirostris

In New Caledonia, the "syndrome 93," which results in mass mortalities of farmed shrimp Penaeus stylirostris, occurs during the transitional and the cold seasons. The transitional season is characterized by an important fall in the average water temp...

Response of the blue shrimp Litopenaeus stylirostris to temperature decrease and hypoxia in relation to molt stage

The effect of different levels of dissolved oxygen (DO) and a decreased temperature combined with severe hypoxia were studied in the blue shrimp Litopenaeus stylirostris in relation to molt stage. In the first experiment, shrimps were submitted to DO...

Diversity of migration strategies among great frigatebirds populations

Migratory behavior varies extensively between bird taxa, from long distance migration to purely sedentary behavior. Variability in migratory behavior also occurs within taxa, where individuals within some species, or even populations, show mixed stra...
