Marine biodiversity Last Updated on 2014-12-15 19:53:24 Biodiversity is now commonly defined as the variety of life in genes, species and habitats. According to the definition of the Convention on Biological Diversity, biodiversity is the variability among living organisms from all sources, including inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems. The three domains of life, bacteria, archaea and eukarya are present in the marine environment. In addition there are viruses. About 230,000 species of marine plants and animals have been scientifically described and a few thousand bacteria and archaea. This known biodiversity only represents a small fraction of the number of species existing, except for the macrophytes and seagrasses which are living in coastal environments and, in general, for the pelagic...

Malaysia- FAO's Information System on Water and Agriculture Last Updated on 2014-12-07 21:15:44 Malaysia is situated in southeast Asia. It consists of two regions: peninsular Malaysia in the west lying between Thailand and Singapore, and the states of Sabah and Sarawak located in the east on the island of Borneo. The two regions are separated by the South China Sea. The total land area of the country is 328 550 km². Malaysia is a federal country, divided into 13 states plus the federal territories of Kuala Lumpur and Labuan Island.. The Food and Agriculture Organization of the United Nations (FAO) leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO is also a source of knowledge and information. In peninsular Malaysia, a mountainous spine known as Banjaran Titiwangsa sepa-rates the east of the... More »
Fisheries and aquaculture Last Updated on 2014-12-07 21:08:51 In 2002 the global production from fishing and aquaculture combined reached about 133 million tonnes. The global yield from capture fisheries is stagnating, but aquaculture has been expanding. The quantities of fish captured remained stable at about 93 million tonnes per year between 1999 and 2002. China and Peru are leading the top ten of countries with the largest catches. The same countries have remained in the top ten for over a decade. Oceans and seas provide 90% of the world's fishery catches. During the past decade marine catches brought to land increased slightly compared to the preceding decade. It should be noted that the quantity of marine fish caught and discarded fell by several million tonnes in the same time period. Trends vary greatly across different regions and for different species. The species yielding the largest harvest is the Peruvian... More »
What Is Aquaculture? Last Updated on 2014-12-07 19:28:34 The term aquaculture broadly refers to the cultivation of aquatic organisms in controlled aquatic environments for any commercial, recreational or public purpose. The breeding, rearing and harvesting of plants and animals takes place in all types of water environments including ponds, rivers, lakes, the ocean, and man-made “closed” systems on land. Aquaculture serves many purposes including: Food production for human consumption; Rebuilding of populations of threatened and endangered species; Habitat restoration; Wild stock enhancement; Production of baitfish; and Fish culture for zoos and aquariums. It is one of the fastest growing forms of food production in the world. Because harvest from many wild fisheries has peaked globally, aquaculture is widely recognized as an effective way to meet the seafood demands of a growing population. Using aquaculture... More »
Species diversity Last Updated on 2014-12-07 19:11:57 Species diversity is a measure of the diversity within an ecological community that incorporates both species richness (the number of species in a community) and the evenness of species' abundances. Species diversity is one component of the concept of biodiversity. Species diversity is influenced by species richness. All else being equal, communities with more species are considered to be more diverse. For example, a community containing 10 species would be more diverse than a community with 5 species. Community A Species Abundance 1 20 2 20 3 20 4 20 5 20               Species diversity is also influenced by the relative abundance of individuals in the species found in a community. Evenness measures the variation in the abundance of... More »
