4.3             Fish catch for Aquaculture Source. Sampling of zooplankton, carrying out plytoplankton studies using ICITA net; Biological research to understand the biology of selected species in various resource groups; Statistical research to assess the biomass of fish stocks involving acoustic surveys for pelagic species, trawl surveys for demersals and the compilation of total annual catch by gear species number and size of vessels in co-operation with the Food and Agriculture Organization of the United Nations (FAO) and the International Commission for the Conservation of Atlantic Tunas (ICCAT); Conducting periodic canoe frame surveys in 1986, 1989, 1992, 1998). The average yield of fishery decreased from 46.8kg/ha in 1976 to 32.6kg/ha in 1998 (lbib). The lake Volta covers a total of 1232 communities (Braimah 2001). Fish is recognized as the most important source of animal protein in Ghana (Aggrey Fynn 2001, Ghana NCU 2001) and all regions of the country, poor or rich, rural or urban (Anon 2003). 17 species of rare butterflies, half of which are found only in Atewa or one other site in Ghana, including the magnificent Papilio antimachus, whose wingspan is the widest in the world. Mali Electric Catfish (Malapterurus minjiriya) is a freshwater fish native to Mali, Burkina Faso, Ethiopia, Ghana, Togo, and Nigeria. Fisheries research in Ghana is carried out mainly by the Marine Fisheries Research Division (MFRD). The Food and Agriculture Organization of the United Nations (FAO), through its fisheries department, facilitates and works to secure the long term sustainable development and utilization of fisheries and aquaculture in Ghana. It is estimated that up to 12% of total national fish product is exported (ibid). It has an average depth of about 19m (Gordon 1999, Braimah 1999) a maximum depth of 90m (Gordon 1999) a maximum operating depth of 84.1m and a storage capacity of 190km (Braimah 1999) and covers an area of 8,480km and a length of 410km (Gordon 1999). Pomacentridae. 7.1             Fisheries in the National Economy. The potential for cage culturing for tilapia is steadily increasing.[4][5]. Sergeant-major. Characiformes. It lives close to the bottom of the river. Snakes are common while marine creatures such as crocodiles and hundreds of fish species live along the coast with the Atlantic Ocean and in Lakes Volta and Bosumtwi. Given that Ghana is known to be only 60% fish self-sufficient and fish availability from local sources are seasonal, fish is imported to fill the seasonal and annual deficits (ibid). Key on the export destination list of Ghana are the European Union, Japan, United States of America, Canada, Togo, Mali, Cote d’Ivoire, Burkina Faso, Benin, Nigeria, Hong Kong and Singapore (ibid). With origins in Northern Africa and the Middle East, Blue Tilapia, which is often blue-gray with a pink-white belly, can be found in abundance in Florida’s lakes, rivers and streams.The adaptability of this species means that it can also live in saltwater, although it thrives in freshwater. A key focus of the FAO is its assistance in the implementation of CCRF. Inland fish catches in Ghana, are taken from Lake Volta, Other Lakes, major rivers and aquaculture (Anon, 2003). A species is the most specific biological category and refers to a group of similar animals that can breed with each other, but not with other species. Year-to-year change in estimated biomass of 41 large mammal species was linked closely to annual harvest of marine and freshwater fish in Ghana (R = 0.73, n = 28 years, P < 0.001). Food and Agriculture Organization of the United Nations, Organisation des Nations Unies pour l'alimentation et l'agriculture, RESUMEN INFORMATIVO SOBRE LA PESCA POR PAISES, Organización de las Naciones Unidas para la Agricultura y la Alimentación. For smoked fish species, Eurostat places Ghana in the first position among the African producing countries in terms of quantity. The annual demand for fish is currently estimated at about 600,000mt (ibid), implying on an annual fish deficit averaging 265,000 mt. Aquaculture is being promoted in at least 7 of the 10 regions of Ghana comprising Greater Accra, Ashanti, Western, Brong Ahafo, Volta, Eastern and Central Regions (Anon 2003).
