We avoid here discussion of the technical aspects of the stock assessment exercises carried out by various agencies but present the estimates of fish-stocks prepared for Gujarat that were officially accepted by the state. In case of aqua-culture, scope exists for bringing more fish species with a focus on food fish, ornamental species and those with potentials for sport and tourism. Growing demand for domestic fresh water fish. Fish produstion can be enhanced in rain fed water bodies by 2 to 4 times. Domestic demand for the fish and processed fish is increasing very rapidly.
In the freshwater, brackish water and the marine aquaculture sector there exist challenges and opportunities to which Dutch companies can respond. History Aquaculture was used in China circa 3000 BC. When the waters lowered after river floods some fishes, namely carps, were held in artificial lakes. Their broods were later fed using nymphs and feces from silkworms used for silk production. The Romans were quite adept in breeding fish in ponds.
Consumer surveys have shown that evidence is mixed on whether people perceive aquaculture as giving rise to environmental and animal welfare problems, and it differs among countries and regions. In Europe, the focus on environmental risks associated with fish consumption is most pronounced in the northern and western countries, such as Belgium, Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Sweden and the United Kingdom (EC, 2008). In Norway, the public was found to be especially aware of environmental topics, owing to the particular importance of the aquaculture industry to their country (Schlag and Ystgaard, 2013). Interestingly, in Germany, overfishing raises more sustainability concerns than does fish farming. Thus
Aquaculture takes place in inland, marine and coastal settings using a variety of methods, including raceways, cages, ponds, tanks, ropes, rafts and racks. Aquaculture has a major advantage over the decreasing capture fisheries as the time of harvest can be synchronized to coincide with market demand (FAO, 2008). Aquaculture is one arm of agriculture that can thrive in any ecological area of Nigeria. According to the Nigerian Fifth National Biodiversity Report, 2015, there are five priority ecological areas of Nigeria which are arid, Guinea savannah woodlands, coastal and marine ecosystem, rainforest belt including montaine forest and wetlands and river basins. As long as water (whether brackish or fresh) which creates the enabling environment for aquaculture industry to thrive is available or provided, aquaculture will do well in any part of Nigeria.
Marine aquaculture is the farming of seafood species that are indigenous to the ocean. According to the National Oceanic and Atmospheric Administration (NOAA), “U.S. marine aquaculture primarily produces oysters, clams, mussels, shrimp, and salmon as well as lesser amounts of cod, moi, yellowtail, barramundi, seabass, and seabream.” Although marine aquaculture can take place in the ocean, using cages on the seafloor or in suspended water columns, most of the aquaculture systems in the U.S. are man made on land, using a recirculating system that reduces and recycles water. But like other forms of farming, aquaculture can lead to negative effects on the environment. The impacts vary upon the type of organism being farmed/raised and the type of system being used.
Many households are engaged in sheep farming and they depend on it for their livelihood. However, the production of these sheep farmers is of small-scale. Approximately 36% of the agricultural land in the N8 development corridor is covered by natural grazing, whilst 61% is cultivated dry land and 3% is under irrigation (The DTEA-FS, MMB Consultant Services, ILO, UOFS, 2012). The farmers in these communal villages around N8 have access to grazing land. They farm mainly with livestock such as cattle, sheep, goats and horses.
Fishponds are built on land either digging or mounding soil around. Soil must be tested for the capacity of retaining water inside to fish culture (Ahmadu Bello University, Zaria, 1994). As Carillo, Hagonoy, Bulacan have a wide range of land, it is a good spot for building ponds however this barangay is usually inundated by the sea water so it is not like what the literature want to pursue. The land is appropriate for cultivating fish on that
Aquaculture, also known as aqua-farming, is now frequently extolled as the “Blue Revolution” – a highly productive source of food, essential for feeding the world’s growing population in light of declining marine stocks. Since the 1990s, the contribution of aquaculture to global food production has been growing at an average compound rate of more than 10%, the world’s fastest growing form of food production (Karen, 2012). In many ways, this blue revolution is analogous to the crop revolution that had spread throughout the world in the 1960s. Much as how the green revolution was lauded as a solution for the problem of world hunger, the blue revolution is hailed as a way to increase the availability of affordable food among the poor and developing
Farming rice fields can be found in the area of the river and the estuary of the river. This area is fertile agricultural land that is affected by the tidal waters of the river. Rice paddy agriculture in South Kalimantan concentrated along the banks of the River, both major rivers such as the Barito River or smaller like Amanda and Martapura, while agricultural fields can be found in the hilly area Meratus. Based on the types of land management, agriculture in South Kalimantan is divided into two, namely, subsistence farming and commercial agriculture. Subsistence farming is traditional farming techniques which are still using simple equipment in land management are moving to meet the needs of the limited.
Wild fish stocks are decreasing due to heavy utilization and an increasing demand for aquatic products; so recently marine aquaculture is one of the most important and quickest growing industries in the world (Asche, 2008). This industry is a substitute for the traditional forms of fish supply and an important source of protein for the growing human population and can relieve the pressures on marine and coastal ecosystems (Lucas and Southgate, 2012). In addition, marine aquaculture can contribute to food security (Godfray et al., 2010; FAO, 2014). Capture fishery production has been relatively static since the late 1980s, while aquaculture has grown considerably in this period (FAO, 2016). World per capita apparent fish consumption increased
