Seasonal Variations in Temperature and Salinity in the Gulf of Guinea

Abstract: A simple linear regression model was used to determine variations in temperature and salinity profile in the coastal waters of Ghana in Gulf of Guinea (GOG) from four surveys, two from each hydrographic season conducted between 2000 and 2002. The model estimated an average sea surface temperature (SST) of 27.13°C for thermocline season and 22.52°C for upwelling season. The average sea surface salinity (SSS) estimated by the model for the thermocline season was 35.24‰ and the upwelling season was 35.56‰. A seas… Show more

“…Irrespective of the supply source, small-and large-scale traders transport locally processed fish to coastal and inland marketplaces where it is sold either retail to consumers or wholesale to traders who then take the fish to more remote markets. The result is that 95% of small pelagic fish landings are for human consumption (Nunoo et al 2015) and 75% of Ghana's total fish production is consumed domestically (Dovlo et al 2016). Fish trade not only contributes directly to FSN by facilitating fish access to consumers, but also contributes indirectly when the incomes generated by fish traders are used to improve the FSN of their households (Kawarazuka and Béné 2010).…”

“…This finding again is supported by the KII where the respondents admitted that the studied communities go fishing all year round. This practice could be so because it was found elsewhere that most fishermen along the coast of Ghana have no alternative source of livelihood and thus may be forced to fish all year round Dovlo et al (2016). Most of the communities (67%) have no local mechanism for periodic closures to help conserve marine resources.…”

“…The first stage is to identify fishermen and the second stage is to randomly interview them to get the required sample in each region/community. Overall, the sample of 400 respondents was carved out of a total of 107,518 fishermen who operate along the coast of Ghana (Dovlo et al, 2016). Following Yamane (1967), the sample is determined as follows;…”

“…Ghana's industrial vessel fleets are classified into three categories: the semiindustrial sector, the industrial sector (mostly comprised of trawlers), and industrial foreign tuna vessels. Together, these two regions have 15 of Ghana's 26 coastal administrative districts, with the total smallscale fisher population estimated at about 26,000 in the Greater Accra Region and 34,000 in the Western Region (Dovlo et al 2016).…”

“…Table 1 shows the number of small-scale fishing fleets and people who engage in fishing in the various localities, as well as the average catch quantities, underscoring the importance of small-scale fishing to the local economies. These communities were drawn from seven of the coastal administrative districts where small-scale fishing constitutes a significant economic activity, and they were purposively selected (Marshall and Rossman 2014) for one or all of the following reasons: (1) their proximity to the commercial fishing port where the industrial fishing vessels land and begin their fishing; (2) their contribution to smallscale fisheries catch; and (3) their listing as a community in Ghana's Fisheries Scientific Division's Marine Canoe Survey Framework of the Ministry of Fisheries and Aquaculture Development (Dovlo et al 2016). Ghana's Fisheries Scientific Division's Marine Canoe Survey indicate that the catch quantities in the communities vary based on a number of reasons, including the number of fishers, the variation in fishing capability in terms of fishing gears, and the seasonal fluctuations in the fishery across the coastal villages.…”
