AB- Eighteen species of amphibia - representatives of nine genera of four
families - were found in the successional forest of Ma Da (South
Vietnam). On the basis of the data obtained in the second half of the
rainy season, a study was made of the utilization by the populations
of the aquatic breeding sites, the main resource limiting population
number Judging by the larvae present in the water bodies, the
dominant species is Polypedates leucomistax and next frequent are
Microhyla heymonsi, M. ornata, and Rana limnocharis. Some of the
species (Theloderma stellatum, Kalophrynus pleurostigma, and several
others) entirely or partially avoid competition due to specificity of
the breeding sites. However, the reproductive resources of the
majority of the species are included in the resources of the dominant
species. Possible competition does not always cause a displacement of
niches or supplantation of part of the species, even if the common
resource is limited.

AB- Fish husbandry and rice culture management factors influencing the
yield of introduced fish in ricefields of the Vietnamese Mekong Delta
were studied by multiple regression analysis, A significant (P <
0.001) regression model was computed in which feed input and duration
of culture period positively, and ricefield area, rice seeding rate
and the year of the survey negatively affected the yield of
introduced, as well as indigenous, fish. The negative impact of
larger ricefields is probably the result of the escape of fish. This
is also probably the reason for the year of survey since the average
yield of introduced fish was 92.5 kg hal in 1995 (because of an
extreme flood) as compared to 164.8 kg ha(-1) in 1994. A high seeding
rate of rice results in a dense stand which suppresses the growth of
fish. Opportunities for improvement of fish production are proper
ricefield construction, reduced seeding rates, stocking fingerlings
early in the dry season and more intensive feeding.

AB- The results of a socio-economical survey of farming systems
practising rice culture with introduced fish, rice culture with
indigenous fish and rice monoculture in the semi-deep waters of the
Mekong Delta, Vietnam, are presented. Rice and fish yields, inputs,
and cost-benefits were computed to evaluate the agricultural effects
of rice with fish culture. Household size, labour availability and
educational level were not significantly different among the three
farming systems, Rice-fish farming systems differed mainly from rice
monoculture by a higher fertilizer/water requirement and less
pesticide use. The total farm cash and net return did not differ
among the farming systems, The main beneficial effects of rice-fish
culture are thought to be related to environmental sustainability,
system biodiversity, farm diversification and household nutrition.
