7 - Fisheriesfisheries, the conservative value of $0.68/kg is used, because although the fish are produced byboth aquaculture and capture fisheries, the relative proportions cannot be estimated. This resultsin an estimate of $1,478 million for the value of the fishery. This is for first sale price only, andso does not include any estimate of the multiplier effects of the fish trade.2.5 Nutritional valueNutrition, health and poverty baseline surveys in Cambodia confirm that fish and aquatic animalsprovide more than 75 percent of animal protein intake in rural areas. 57 In the lowland areas of theLMB, where the bulk of the population lives, between 40-80 percent of animal protein is suppliedby aquatic animals. 58The average protein requirement for adults is between 0.8-1.0 g protein/kg body weight/day. In theLMB this is normally, or very nearly, met on an annual basis. 59 However, in some areas of the LMB,seasonal malnutrition is quite common. 60 Rice provides more than half the daily protein requirementin the LMB, but it is deficient in lysine, an essential amino acid. Fish and other aquatic productscontain 33 percent more lysine than terrestrial animal protein sources such as poultry, beef andpork. 61Calcium intake is also particularly important in human nutrition for skeletal growth of young children,for foetal growth, for lactating mothers and for the elderly to prevent brittle bones (osteoporosis).The World Health Organisation and the Food and Agriculture Organization (FAO) recommend adaily intake of 400-500 mg of calcium per day for adults and 500-700 mg per day for adolescents. 62Milk and other dairy products supply most of the calcium used by humans in western countries. InSoutheast Asia, where rice and most fruits lack calcium, it is primarily provided by small fish, thatare often eaten whole, and other traditional products made from small fish. 63 Small dried fisheaten whole contain more than 1,000 mg of calcium per 100 g, while dried fermented fish exceeds2,000 mg of calcium per 100 g. Importantly, the calcium uptake by the human body is the same forsmall fried fish eaten whole as it is for fresh milk. 64 As well as supplying animal protein andminerals such as calcium, fish are important in the human diet as a source of vitamins (includingvitamin A). 65109
