Les pagures du Viet-Nam. 1. Le genre Diogenes Dana

This first note deals with Diogenes of Group II (cf. Forest, 1952, p. 11). This group contains a number of highly variable species which are, in some cases, poorly characterized due to the vagueness of the original descriptions. Diogenes from Nhatrang belong to four different species but only one of them was identified with a species already described: Diogenes avarus Heller. The other three described and figured in this paper, are probably Diogenes Goniochirus, and D. leptocerus, D. serenei sp. nov.

Les pagures du Viet-Nam. II. Sur quelques espèces du Genre Calcinus Dana

The collections of the Oceanographic Institute of Vietnam include several species of hermit crabs of the genus Calcinus Dana. Three of keys were studied by Fize and Serene (1955): C. herbsti Man, C. gaimardi H. Milne Edwards and C. latens Randall . The seventy specimens belong to four species. The first one, C. minutus Buytendijk, was described by Indonesia in 1937; the second one, represented by a single small specimen is related to C. spicatus Forest. Finally, two other are Calcinus vachonis sp. November and Colcinus pulcher sp. nov.

Eumedoninae du Viet-Nam (Crustacea) (avec un bibliographie de la sous-famille)

This study provides elements for the revision of the subfamily Eumedoninae. The detailed description of the specimens led to the presence of characters that are common to different genera and many species. A bibliography and a list of genera and species of the subfamily identified in this bibliography is given.

Éponges intercoditales de Nha Trang (Viet Nam)

Thanks to the effort of many spongologists from worldwide, we know the most common sponges in the Indo-Pacific area. The author gives a description of 28 intertidal sponges collected in Nha Trang, Vietnam.

Les poissons d'importance commerciale au Viet-Nam

The fishery products represent one of the most important resources in Vietnam. The paper focuses on distribution, fishing gears, fishing seasons and current use of commercial fish species.

Zoanthaires du Viet-Nam

The present note deals with a description of Zoanthids found on the coast of Vietnam.

Les hapalocarcinidés du Viet-Nam

Serene (1936) and Dawydoff (1952) reported several species of Hapalocarcinids on Indochina corals. This study does not aim to a revision of known species, but a preparatory work for next revisions. A great part of their work was dedicated to the description of species; two preliminary notes had already described 12 new species. This work interested 22 species, 6 already known, 12 already described briefly and 4 new.

Nudibranches du Viet-Nam

This study deals with detailed descriptions of nudibranchs belonging to the collection of the Oceanographic Institute of Vietnam.

Community-based fish culture in seasonal floodplains

During the rainy season in extensive river floodplains and deltaic lowlands, floods render the land unavailable for crop production for several months each year. These waters are considerably underutilized in terms of managed aquatic productivity. This raises the opportunity to enclose parts of these floodwater areas to produce a crop of specifically stocked aquatic organisms aside from the naturally occurring ‘wild’ species that are traditionally fished and are not affected by the culture activity, resulting in more high-quality, nutrient-dense food production and enhanced farm income for all stakeholders, notably the poor. The WorldFish Center and its national partners recently tested the concurrent rice-fish culture in the shallower flooded areas and the alternating rice-fish culture in the deep-flooded areas of Bangladesh and Viet Nam through a community-based management system. Results indicate that community-based fish culture in rice fields can increase fish production by about 600 kg/ha/year in shallow flooded areas and up to 1.5 t/ha/year in deep-flooded areas, without a reduction in the rice yield or wild fish catch.

A comparative ecological study on internationally important wetlands of Khoor-e-Kolahy and Tiab

Ecological study on Kolahy and 'flab estuaries were carried out during 1996-1997. Water and sediment sampling was done seasonally. In order to study the physical and chemical characteristic of the water, various animal fauna from different material niches including planktons and fish from water, benthousi from the sediment , and surface living animal such as Arthropod (Crabs) and Waterbirds were identified. I he result shoved, that water salinity of both estuaries was the same as the general salinity existing its the Persian Gulf water, and its variation is same IN those waters Minimum water salinity in both estuaries are seen during Bahairdan or early winter mooth(Jaa.), which is about 31ppt and Maximum is during .rirldlun.) or summer mouth at about 19 ppt. Dissolved otygen and pH are slime as the general Persian Gulf waters., Dissolve Oxygen being directly associated to temperature and its fluctuation is between 7- Sing/I and pH between 7.5-LS. The animals of both estuaries are almost similar having a sal factory species diversity . The birds of the region are often seasonal migrants , the maximum population of which occurs in winter season and the minimum during summer month. Nam coverage is richer in Tiab than Kolahy estuary, where in Kolahy a signal Mangrove tree is in exigence. 'Ile total coverage of Mangrove forest in Tiab is estimated about -29 hec.Both estuaries are included with in the international Ramsar Convention sites in 1971. Due to national importance of these estuaries inproviding refugee for various birds species and also hinting grounds and access traffic for local fishing vehicles, Actiog as an important access for various inhabitancy living with these area of the Persian Gulf. Due to importance or prawn aquacultur for the economical well being of local inhabitance, these areas provide a suitable grandees for prawn production. I-test statistics show, there are no significant difference among various invertebrate and vertebrate animals. In over all out look 21) phytoplankton genera, 21) zeoplankton genera 17 miafauna and 32 roaerofauna genera , 11 different species Carcineacearions and 119 species of walerbirds were identified with in the Tiab and Kolahy estuariesregioos. The X statistic show that the animal density is directly associated to season. Where density of miofauna and maerofauna in both estuaries are in maiticrourn during summer and the minimums existing during the winter season. In addition the bentic invertebrate population density in closlly association to birds population density since , the later, feeds on the former animals. Where the increasing in bird population density during the winter season, the bentic invertebrate animal population density decreases. The over all trend of animal population density in winter tend to increased towards the summer seasons, which this is due to climatic conditions of the region. The bird population on the contrary to other animals of both estuaries tend to increase from summer towards the winter seasons and which this bird population density is in maximum in winter with in the region.
