In Mekong delta, mangrove forest distributes along the coastline of 700 km and it is a homeland for mud crab in tropical areas. The mud crab becomes potential to be alternative species from failed shrimp farming. Particularly, mud crab hatchery has been introduced and operated recently at Bac lieu, Tra vinh, Soc Trang, Ben Tre, Kien giang and Ca mau provinces. However, the survival from zoea stage to crablet stage 1 is low at approximately 5%. In addition, like shrimp rearing, the mud crab hatchery is using antibiotic as major treatment to prevent bacteria and fungi.

The Research Centre for Forest Tree Improvement (RCFTI) is a unit within the Forest Science Institute of Vietnam (FSIV) which specialises in tree improvement research and delivery of genetically improved seed and planting stock to meet the planting requirements of the Government of Vietnam (GoV) as well as community and private sector plantation programs. RCFTI carries out an active program of research at stations throughout Vietnam, with its principal research station at Ba Vi.

Key features of Seedling Seed Orchard (1) - A seedling seed orchard is developed by selectively thinning a progeny trial which tests many different families of a species. - The progeny trial is assessedand analysedto find out which families and trees within families are growing best. - Inferior trees are removed in two or more selective thinnings, as the stand develops. - Inferior families may be completely removed –all trees cut down.

Provenance • Place where seed was collected • Refers to natural forests, not plantations • Provenance boundaries not always well defined • Provenances may have different genetic adaptation. Subdivision of a species, with genetically similar individuals. • Sometimes synonymous with provenance. • Races separated using observed differences. • For example, wood basic density, bark thickness, and flowering patterns have been used to define E. globulusraces

Common carp is one of the most important cultured species in Vietnam. The goal of the carp breed program was creation of a common carp breed with stable genetic qualities such as fast growth, high survival rate and attractive appearance. In the first phase (1981-1985) the program focused on the assessment of the original carp varieties, which should be used as initial materials for selection.

Genetic improvement of fish species is considered a priority area for research and development by the government of Viet Nam, particularly in the context of rural development, food security and poverty alleviation. The current proposal has been developed in consultation with Vietnamese staff of participating institutions. The project builds upon the existing collaborative links between Deakin University and the Research Institutes of Aquaculture (RIAs) in Viet Nam.

The project is designed to complement an ACIAR project on Fruit Flies in Vietnam. Whereas the ACIAR project will investigate the pest fruit fly species, the crops they attack and levels of damage inflicted, this proposed project under CARD is designed to equip laboratories and staff at three centres under MARD, provide an experimental foundation for production of protein for fruit fly control and animal food and instruct farmers in fruit fly pest management.

In order to overcome the limitation of land available for aquaculture in the central costal region of Vietnam and to reduce organic pollution in traditional integrated fish farming, a new method was developed called the ‘improved VAC’ In traditional VAC systems the manure from farm animals is released into fish ponds whereas in the ‘Improved VAC’ the manure is used for earthworm culture. The worm production is then used to feed high value fish species in tanks.

In recent years Vietnam’s forest coverage has undergone rapid expansion, with a marked increase in plantings of exotic species of Eucalyptus, Acacia and Pinus. This expansion provides excellent opportunities for new international export markets for timber products. However it also represents new and increased risks from forestry pests and diseases, which in outbreak circumstances can have catastrophic consequences on plantation establishment and productivity. These risks come from pest and disease species already established in Vietnam, and exotic species not yet present in the country....

The culture of striped catfish, Pangasianodon hypophthalmus (Sauvage), or “ca tra” in Vietnamese in the Mekong Delta of Vietnam, can be considered as a unique aquatic farming system in many ways. Production is the fastest growth recorded in any aquaculture sector, ever, based on a single species, superseding the production per unit for any form of primary production. Stripped catfish aquaculture now need to be improved in many aspects and environmental issues need to be paid more attention to ensure the sustainable development.

Aquaculture is a general term for the resource, giving the human animal from the environment and human exploitation, aquaculture harvest used for food, raw materials or sold on the market. In the aquatic species, most commonly used fishing activities, aquaculture and exploitation of fish.
