Analyse des résultats d'une ferme d'élevage de crevettes sur 20 années : SODACAL 1984-2004. "Elasticité" de la capacité de production d'un écosystème bassin crevetticole ArchiMer
Della Patrona, Luc.
SODACAL prawn farm which was set up as a pilot farm for the development of a prawn industry in New Caledonia, saw its production exponentially rise from 1984 to 1992 (to 400 t/year, then experienced a sharp drop in 1993 (250 t/year) which carried on until 1997, and finally rose back to a stabilizing level around 400 t/year until 1999. The study analyses the difficulties observed before and during the drop of production. Among them, mortality outbreaks, other biological perturbations (benthic mat clearing and crab and fish mortality) and focus on the noxious state of the bottom (reduced and smelling sulfide hydrogen). It particularly shows that Syndrome 93 outbreaks could be observed on this farm from 1990. The analysis highlights the particular climatic...

Colonization of coastal environments by foraminifera: insight from shrimp ponds in New Caledonia (sw Pacific) ArchiMer
Debenay, J. -p.; Della Patrona, Luc; Goguenheim, H..
The objectives of this study were to observe foraminiferal colonization patterns and behavior in shrimp ponds in New Caledonia during a shrimp-growing (farming) cycle. Weekly collecting at 10 stations in 8 shrimp ponds yielded a total of 170 samples accompanied by environmental data. Seawater pumped from the nearby ocean filled the ponds at the beginning of the growth cycle and its daily renewal maintained salinity at 32-39, and supplied the ponds with influxes of smaller, mostly juvenile, foraminifera. A few days after initial filling, the pioneering species Ammonia tepida and Quinqueloculina seminula appeared, with A. tepida dominant. Their high reproduction rates increased both living and dead assemblage densities during the first 10 weeks. Populations...

Concentrations and fractionation of carbon, iron, sulfur, nitrogen and phosphorus in mangrove sediments along an intertidal gradient (semi-arid climate, New Caledonia) ArchiMer
Deborde, Jonathan; Marchand, Cyril; Molnar, Nathalie; Della Patrona, Luc; Meziane, Tarik.
In mangrove ecosystems, strong reciprocal interactions exist between plant and substrate. Under semi-arid climate, Rhizophora spp. are usually predominant, colonizing the seashore, and Avicennia marina develops at the edge of salt-flats, which is the highest zone in the intertidal range. Along this zonation, distribution and speciation of C, Fe, S, N, and P in sediments and pore-waters were investigated. From the land-side to the sea-side of the mangrove, sediments were characterized by I/ increase in: (i) water content; (ii) TOC; (iii) mangrove-derived OM; II/ and decrease in: (i) salinity; (ii) redox; (iii) pH; (iv) solid Fe and solid P. Beneath Avicennia and Rhizophora, TS accumulated at depth, probably as a result of reduction of iron oxides and...

New Caledonian shrimp farming feasibility studies started in the mid-seventies. Today ca. 2000 tons of Litopenaeus stylirostris, introduced in 1978, are semi-intensively produced each year. Since fifteen years, production has been impacted by two seasonal vibriosis, the “Summer” syndrome caused by Vibrio nigripulchritudo in relation to pond bottom and water column quality, and the “Winter Syndrome” caused by Vibrio penaeicida in relation to drastic temperature drops . With the ambition of elucidating processes possibly leading to mortality outbreaks in ponds, Ifremer has been conducting a research program since 2003 under the DESANS project (2003-2006) and the present DEDUCTION project, equally funded by the South and North Provinces and by the Government...

Foraminiferal assemblages: tools for assessment of shrimp pond conditions ArchiMer
Debenay, Jean-pierre; Della Patrona, Luc; Herbland, Alain; Goguenheim, Hemitti; Peignon, Jean-marie.
Meiofauna is a functional group made of small benthic metazoans 45 to 500µm in size. Although protista, foraminifera living in this kind of environment are often put in to the meiofauna. Meiofauna has been studied in New Caledonia for its double role as biological indicator for monitoring pond health status and as shrimp forage. Suitability of EOM (easily oxidized material), SOD(sediment oxygen demand),as new biochemical tools for monitoring shrimp pond health was assessed in an environmental survey aiming to assess the role of the water/sediment interface in the occurrence of the summer syndrome vibriosis. EOM, SOD and redox were correlated with shrimp survivals. Lowest meiofauna biomass and abundance were concomitantly found in the most polluted station....

Grow-out of sandfish Holothuria scabra in ponds shows that co-culture with shrimp Litopenaeus stylirostris is not viable ArchiMer
Bell, J; Agudo, N; Purcell, S; Blazer, P; Simutoga, M; Pham, Dominique; Della Patrona, Luc.
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 ponds were designed to detect any deleterious effects of sandfish on shrimp, and vice versa. These experiments showed that a high stocking density of juvenile sandfish had no significant effects on growth and survival of shrimp. However, survival and growth of sandfish reared with shrimp for 3 weeks were significantly lower than for sandfish reared alone. Increased stocking density of shrimp also had a significant negative effect on survival and/or growth of sandfish. A grow-out trial of juvenile sandfish in...

Les sols des fonds de bassins et leur gestion durant les assecs. Etat des connaissances ArchiMer
Della Patrona, Luc; Brun, Pierre; Herbland, Alain.
Shrimp culture in New Caledonia has developed according to the "intensified" semi-intensive model which uses ponds that stretch over several hectares. Local shrimp farms are for the most part installed in "tannes", barren, highly saline areas of the back mangrove forest. These areas generally have impermeable silty clay soils that have biogeochemical features particularly appropriate for benthic life and are often immersed by tides. During the six months of the grow-out phase, the "pond ecosystem" undergoes an increase in potential, progressing from an initial state of "natural lagoon" to a "grow-out pond" that is highly enriched with degrading organic matter....

Meiofauna distribution in a mangrove forest exposed to shrimp farm effluents (New Caledonia) ArchiMer
Della Patrona, Luc; Marchand, C.; Hubas, C.; Molnar, N.; Deborde, J.; Meziane, T..
Meiofauna abundance, biomass and individual size were studied in mangrove sediments subjected to shrimp farm effluents in New Caledonia. Two strategies were developed: i) meiofauna examination during the active (AP) and the non-active (NAP) periods of the farm in five mangrove stands characteristics of the mangrove zonation along this coastline, ii) meiofauna examination every two months during one year in the stand the closest to the pond (i.e. Avicennia marina). Thirteen taxonomic groups of meiofauna were identified, with nematodes and copepods being the most abundant ones. Meiofauna abundance and biomass increased from the land side to the sea side of the mangrove probably as a result of the increased length of tidal immersion. Abundance of total...

Mitigation of sea level rise effects by addition of sediment to shrimp ponds ArchiMer
Della Patrona, Luc; Beliaeff, Benoit; Pickering, T..
In New Caledonia barren salt-pans located landward to mangroves are used for the construction of shrimp ponds. The existing farms are jeopardized by the projected rise in the sea level, because the landward boundaries of ponds are situated at the elevation reached by spring tides. One low-cost strategy for mitigating the effects of sea level rise is to raise the level of the bottom of ponds. To test the effectiveness of such an adaptation, we built 4 experimental ponds in the low-lying zone of an existing 10 ha shrimp pond. The level of the bottom of 2 ponds was raised by adding about 15 cm of agricultural soil. Placing agricultural soil in the pond did not impair the functioning of the shrimp pond ecosystem. On the contrary, it resulted in unexpectedly...

Seasonal Pattern of the Biogeochemical Properties of Mangrove Sediments Receiving Shrimp Farm Effluents (New Caledonia) ArchiMer
Marchand, Cyril; Molnar, N.; Deborde, Jonathan; Della Patrona, Luc; Meziane, Tarik.
Coastal tropical shrimp farming may impact the adjacent ecosystems through the release of large quantities of effluents rich in nutrients. In New Caledonia, mangroves are considered as a natural biofilter to reduce impacts on the surrounding World Heritage listed lagoon. Our main objective was to understand the influence of effluent discharge on the biogeochemistry of mangrove sediments. A monitoring of the physico-chemical parameters of mangrove sediments was carried out during a whole year, including active and non active periods of the farm. The parameters studied were: i) benthic primary production (Chl-a concentrations), ii) physico-chemical parameters of sediments (redox potential, pH, salinity, TOC, TN, TS, δ13C and δ15N), iii) concentrations of...

The impact of easily oxidized material (EOM) on the meiobenthos: Foraminifera abnormalities in shrimp ponds of New Caledonia; implications for environment and paleoenvironment survey ArchiMer
Debenay, J.p.; Della Patrona, Luc; Herbland, Alain; Goguenheim, H.
This study was carried out in shrimp ponds from New Caledonia, in order to determine the cause of the exceptional proportion of abnormal tests (FAI) (often >50%, sometimes >80%). FAI was positively correlated to the quantity of easily oxidized material (EOM) deposited on the bottom of the ponds and to the sediment oxygen demand, and negatively correlated to redox. These results suggest that a very high FAI is a potential indicator for great accumulations of native organic matter, leading to a high sediment oxygen demand. When studying ancient sediments in core samples, exceptional abundances of abnormal tests may indicate periods of high accumulation of EOM, and therefore of oxygen depletion. This finding should help in better management of...
