An Investigation of Fish Catch Data and Its Implications for Management of Small-scale Fisheries of Ghana
نویسنده
چکیده
Most statistical information on fish catch in Ghana and that of many other African countries are deficient in supporting effective fisheries management. Fish catches were examined between January 2009 and December 2010, to enhance the management of small-scale fisheries of Ghana. The methods employed were: Fish Catch Assessment (FCA) and documents analyses. The case study focused on four important fishing communities, namely: Elmina and Ahwiam (coastal communities); and Kpong and Small London (inland communities). The results provide evidence from empirical data to confirm observed declining Catch Per Unit Effort (CPUE) and therefore declining fish abundance in Ghanaian water, both freshwater and marine. The average CPUE (kg/canoe/day) for 2009/2010 were: 22.72, 10.57, 44.28 and 133.81 for Small London, Kpong, Ahwiam and Elmina, respectively. There were significant differences in CPUE among habitats and sites (p<0.05). Annual fish catch estimated from CPUE data were as follows: freshwater habitats Small London (716.04 tons) and Kpong (186.68 tons); marine habitats Elmina (4716.80 tons) and Ahwiam (630.99 tons). A total of 21 and 18 fish species were identified at Kpong and Small London, respectively. Furthermore, a total of 71 and 79 fish species were identified at Ahwiam and Elmina, respectively. For management and sustainability of fishery resources in relation to the small-scale fisheries of Ghana and the sub-region as a whole, it is recommended that fishery managers, policy makers and all relevant stakeholders assiduously work together to reverse declining CPUE by reducing fishing effort and encourage income diversification and wealth creation.

Amidst overexploited fisheries and further climate related declines projected in tropical fisheries, marine dependent small-scale fishers in Southeast Asia face an uncertain future. Yet, small-scale fishers are seldom explicitly considered in regional fisheries management and their contribution to national fish supply tends to be greatly under-estimated compared to industrial fisheries. Lack of...

Hilsa shad (Tenualosa ilisha Hamilton, 1822) is a migratory fish and as one of the most important species in the southern parts of Iran, so that during the last decade, the amount of its catch has fluctuated a lot. Due to the limited data available on the stock of this species in southern waters, it is not possible to use models based on complementary data to assess its stock. In the present st...

The problem of overexploitation in global fisheries is well-recognized. However, published assessment of fisheries spatio-temporal trends at the national scale is lacking for many high biodiversity developing countries, which is problematic since fisheries management is often implemented at the local or national levels. Here, we present the long-term spatio-temporal trends of Philippine fisheri...

Among the various species of small pelagic fish, Sardinella sindensis (Day ,1878) has high economic and ecological importance and is one of the most important species exploited by fishermen. In recent years, the catch rate of this species has increased, and due to the limited data available on its stock in southern waters, it is not possible to use models based on the complementary data to asse...
