  • 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.

  • The concern I want to raise in this chapter is related to the relationship between indigenous identities, knowledge systems and indigenous values and world views compared to world views found in South Africa’s new curricula after new dispensation. What are the values the indigenous pupils meet at home? Do they concur with those of the new curricula after 1994? The rationale for this focus is related to the question of whether the South African primary school is ‘their school’, i.e the school for the majority of South African children in terms of culture and knowledge....

  • This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location.

  • Nearly six tenths of the earth's land surface receive an annual rainfall of less than twenty inches, and can be reclaimed for agricultural purposes only by irrigation and dry-farming. A perfected world-system of irrigation will convert about one tenth of this vast area into an incomparably fruitful garden, leaving about one half of the earth's land surface to be reclaimed, if at all, by the methods of dry-farming.

  • Bivalve culture such as clam production is a promising activity as it is more profitable despite a low production rate. However, clam culture has the disadvantage of mainly relying on capture of seed source from the wild. At the same time, due to disease outbreak in the prawn farming sector as a consequence of water deterioration, there has been an overall reduction in aquaculture production. Clam is recognized as a water cleaning machine(filter feeder), thus water quality will be improved if clam can be incorporated into the shrimp farming system.

  • 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.

  • 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.
