This study was aimed at assessing how efficient the small - scale fishing units in Lagos State, Nigeria use the monetary inputs: costs of gear repairs, craft repairs, fuel, fishing losses, hired labor, and the residual costs of craft and gear. Between January and December, 113 mechanized and 43 non-mechanized fishing units in 21 purposively chosen coastal villages were surveyed bi-monthly through questionnaire administration. The input and output (earnings) data were analyzed using the linear regression and Cobb-Douglas technique in monetary terms and Ordinary Least Square methods to determine the elasticities of the fishing units in the wet and dry seasons. The regression output for the non-mechanized category produced good fits for the yield models with adjusted R 2 values range of 0.88 in the wet to 0.98 in the dry seasons. The mechanized category showed respective regression outputs of AR 2 of 0.94 and 0.62. The Durbin-Watson statistic showed moderate multicollinearity amongst the chosen variable inputs. The non-mechanized category had three significant explanatory variables in the dry season while five were significant in the wet season at the 0.05 level. The mechanized category had significant F-ratio values at the 0.05 level in the seasons. The seasonal technical efficiency evaluated using the chosen cost variables showed that there was inefficient combination of the inputs for optimal production. 2001-01-01T00:00:00Z http://hdl.handle.net/1957/30957 An Economic Analysis To Sustainable Fisheries Management Lokina, Razack B. The coastal zone is a dynamic area surrounding the interface between land and sea. The coastal area and its resources offer great benefits and opportunities for human use. Most coastal activities in Tanzania rely on the natural resources that the coast offers (fishing, forestry, agriculture, tourism, mining, salt production mariculture etc). Therefore the condition of the coastal ecosystem and social well being are closely linked. The challenge is to maintain and improve the resources base on which those activities are dependent, while developing new economic opportunities in a way that benefits the people of the coast and the nation as a whole. A major constraint is the inadequate institution and legal framework for coastal management. Economics is about efficient allocation of resources. In normal cases market forces provide efficient allocation of resources. In fisheries, however, market forces alone can not produce an efficient allocation. And as it has been evident in this paper there is already overfishing in most of the offshore waters where majority of artisan fishernen concentrate. Thus calling for policy intervention to rescue the stock from depletion. This should include licencing, seasonal closure; finding alternative economic activities to fishermen, and community based conservation approach can as well be instituted. 2001-01-01T00:00:00Z http://hdl.handle.net/1957/30956 Fishing Versus Farming in a Fresh Water Swamp in Trinidad in the Caribbean Pemberton, Carlisle A.; Fridie, Marsha L. This paper compares the status of fishing to farming in the Nariva Swamp, on the eastern coast of the island of Trinidad, in the country of Trinidad and Tobago. This swamp is one of international significance, since it is a home to the endangered animal, the manatee (Trichecus manatee). Also the swamp has a large population of two aquatic species of economic importance in Trinidad and Tobago - the armored cat-fish or cascadura (Hoplosternum littorale) and the ampulariid snail or black conch (Pomacea urceus). Residents of the area include in their diet the consumption of these species, as well as exploit them commercially. The paper is based on two surveys in the swamp, one was of 99 occupiers of plots, to determine their economic activities and the other survey was of 33 households, to determine the importance of fish from the swamp in their diets. The analysis in the paper showed that farming was now the dominant economic activity in the swamp, both in terms of income received as well as the amount of labor utilized. The residents did consume fish from the swamp, but this fish was not the major source of protein. Poultry and poultry products, especially chicken were the preferred protein sources. Farming was seen as a threat not only to fishing, but also to the native flora and fauna of the swamp and the paper called for urgent studies of the impact of such extensive farming on the ecology of the swamp. 2001-01-01T00:00:00Z http://hdl.handle.net/1957/30955 Economic effects of marine protected areas on small-scale fisheries: a case study of the trawl ban in the Gulf of Castellammare, Sicily Whitmarsh, David B.; James, Carl; Pickering, Helen; Pipitone, Carlo; Badalamenti, Fabio; D'Anna, Giovanni Despite growing interest in Marine Protected Areas, relatively little is still known in practice about their economic impact or their distributional consequences for stakeholders. The present paper, based on an EU-funded project, attempts to shed light on this issue by examining the economics of an artisanal fishery operating in an area of NW Sicily from which trawlers have been excluded. The main issues examined relate to the financial performance of trammel net vessels, focussing especially on (i) current profitability levels, (ii) financial implications of changes in catch rates, (iii) financial viability of capital investment and (iv) comparative performance of vessels inside and outside the trawl ban area. 2001-01-01T00:00:00Z
