Résumé : The present development of Peneid shrimp culture is limited by the problem set by the routine obtainment of reproduction in captivity. In Polynesia where no species of commercial interest is found naturally, this obtainment is a necessary prerequisite. The observations at the Centre Océanologique du Pacifique of CNEXO were made on 6 species of the genus Penaeus (P. merguiensis, P. aztecus, P. japonicus, P. monodon, P. vannamei and P. stylirostris) raised and maintained in 12 m² outdoortanks. At temperatures, between 25 and 32°, a salinity of 35 and a pH of 8,2, maturations and spawnings are seen throughout the year and several generations were obtained : P. merguiensis, F7 ; P. aztecus et P. japonicus, F3 ;P. monodon, F2 ; P. stylirostris and P. vannamei F1. For P. aztecus et P. mondon maturation is induced by unilateral eyestalk ablation. The animals behavior copulation and external signs of ovarian, development are described. The factors which seem essential to the proper progress of maturation are the temperature, the light intensity, the food and the state of health of the animals.
Le développement des élevages de crevettes Pénéidés est actuellement limité par les problèmes que pose l'obtention en routine de la reproduction en captivité. En Polynésie où aucune espèce d'intérêt commercial ne se trouve à l'état naturel, cette obtention était un préalable nécessaire. Les observations effectuées au Centre Océanologique du Pacifique du CNEXO ont porté sUr 6 espèces du genre Penaeus (P. merguiensis, p. aztecus, P. japonicus, P. monodon, P. vannamei et P. stylirostris) élevées et maintenues dans des bacs extérieurs de 12 m² en circulation ouverte. Avec des températures variant de 25 à 32°, une salinité de 35 et un pH voisin de 8,2, maturations et pontes s'obserVent toute l'année et plusieurs générations ont été obtenues : P. merguiensis, F7 ; P. aztecus et P. japonicus, F3 ;P. monodon, F2 ; P. stylirostris et P. vannamei, F1. Pour P. aztecus et P. mondon, la maturation est induite par épédonculation unilatérale. Le comportement des animaux, la copulation et les signes extérieurs du développement des ovaires sont décrits. Les facteurs qui paraissent essentiels au bon déroulement du processus de maturation sont la température l'éclairement, l'alimentation et l'état de santé des animaux

Résumé : At least six virus diseases are presently known in cultured penaeid shrimp. Each of these six penaeid virus diseases (BP = Baculovirus penaei ; MBV = Penaeus monodon -type baculovirus (including PBV of Australian penaeids); BMN = baculoviral midgut gland necrosis; HPV = hepatopancreatic parvo-like virus; IHHNV = infectious hypodermal and hematopoietic necrosis virus; and REO = reo-like virus of the hepatopancreas) may be comprised by a multitude of individual strains, some of which are highly pathogenic to some penaeids, while being of little importance to others.

Résumé : Since 1975, maturation and spawning in captivity of Penaeus monodon has been achieved in the 'Centre Océanologique du Pacifique', a CNEXO Centre in Tahiti. The five first animals have been imported from Fiji Islands and in May 1979, four generations-have been obtained. Under the rearing conditions followed at the Centre, reproduction is achieved all throughout the year. Maturation is induced by unilateral eyestalk ablation on pond reared animals maintained in tanks on adequate food. Results concern mating behaviour, ovarian development, number of spawnings per female and egg viability. The rearing and the maintenance conditions of the captive broodstocks are particularly important to obtain reliable results necessary to sustain commercial hatcheries. Mass production of postlarvae is routinely achieved. [NOT CONTROLLED OCR]

Résumé : Three shrimp species, Penaeus monodon, P. stylirostris (Panama and Mexican strains) and P. vannamei have matured and spawned in captivity at the Centre Océanologique du Pacifique (COP) laboratory. The shrimp, originally stocked as juveniles or postlarvae, were reared to adult size in tanks and ponds and have completed the cycle: F3 generation for P. monodon, F2 for P. stylirostris (Panama strain) and P. vannamei and F1 for P. stylirostris (Mexican strain). Maturation occurs naturally under our rearing conditions or is induced by unilateral eyestalk ablation. Details are given on mating behavior, ovarian development, number of spawnings, egg viability and maintenance of captive brood stock. Partial results so far obtained for P. monodon and P. stylirostris clearly show a reared brood stock could sustain a commercial hatchery. [NOT CONTROLLED OCR]

Résumé : The tremendous development of penaeid shrimp culture across the world over the past twenty years has led to international trade in eggs, larvae and spawners of the best shrimp species for aquaculture. Trade has involved, in particular, the following species: - Penaeus japonicus from Japan to Europe, the Pacific Islands and South America - P. monodon from South-East Asia to almost all tropical countries - P. vannamei and P. stylirostris from countries along the Pacific coast of South and Central America to the United States of America, the islands of the South Pacific, countries along the Atlantic coast of the Americas and certain countries in Africa. In the 1980s, research conducted by American and French teams enabled the breeding of stocks of spawners in captivity. This resulted in the establishment of lines of captive broodstock outside natural areas of distribution, and the development of new breeding farms in previously unproductive regions. Trade related to movements of these species is facilitated by the absence of legislation in most countries; even when such legislation does exist, it is not always applied These practices have led to the rapid development of world shrimp production, but have also contributed to the dissemination of pathogens. In recent years, the occurrence of serious epizootics - occasioning heavy losses world-wide - has led to a more cautious approach involving trade of post-larvae obtained from captive broodstock in which thorough control measures have been implemented for known diseases. Trade in wild shrimp will probably be abandoned progressively, to avoid the risk of introducing new pathogens. The main challenges for research in the near future are the development of diagnostic tools, to enable continuous control of captive broodstock, and the selection of strains which are resistant to the principal pathogens affecting these species.

Résumé : This study is an attempt to produce an assessment of the impact of shrimp aquaculture in the Mekong Delta (Viet Nam) on mangrove ecosystems. For this exercise we selected two sub-areas (Ca Mau and Tra Vinh provinces) encompassing a variety of land uses and ecological conditions. Twenty stations in Tra Vinh and 15 stations in Ca Mau have been surveyed several times from September 2000 to March 2002. Field investigations included mangrove soils studies, measurements of pH and salinity of the water, analysis of mangrove flora, and density and structure of the vegetation. Four Systeme Probatoire de l'Observation de la Terre (SPOT) scenes were used for the discrimination of mangrove types and for the delineation of landscape units. For the first time, five ecologically distinct landscape classes were identified and delineated. Their possible links with the farming and yields of high valued species of shrimps, especially the giant tiger shrimp (Penaeus monodon) destined for export markets, need further studies. Since 1965, about 30% of mangrove ecosystems have been lost in Ca Mau Province and more than 30% of present mangroves are replanted monospecific stands. To the best of our knowledge, this is the first study which demonstrates that, in spite of deep and ancient man interactions in the Mekong Delta, five ecologically distinct classes of land use can be defined. Satellite surveys confirm a clear distribution of landscape units with possible links with shrimp aquaculture potentialities.
