Description of economic data collected with a random sample of commercial reef fish boats in the Florida Keys

This study summarizes the results of a survey designed to provide economic information about the financial status of commercial reef fish boats with homeports in the Florida Keys. A survey questionnaire was administered in the summer and fall of 1994 by interviewers in face-to-face meetings with owners or operators of randomly selected boats. Fishermen were asked for background information about themselves and their boats, their capital investments in boats and equipment, and about their average catches, revenues, and costs per trip for their two most important kinds of fishing trips during 1993 for species in the reef fish fishery. Respondents were characterized with regard to their dependence on the reef fish fishery as a source of household income. Boats were described in terms of their physical and financial characteristics. Different kinds of fishing trips were identified by the species that generated the greatest revenue. Trips were grouped into the following categories: yellowtail snapper (Ocyurus chrysurus); mutton snapper (Lutjanus analis), black grouper (Mycteroperca bonaci), or red grouper (Epinephelus morio); gray snapper (Lutjanus griseus); deeper water groupers and tilefishes; greater amberjack (Seriola dumerili); spiny lobster (Panulirus argus); king mackerel (Scomberomorus cavalla); and dolphin (Coryphaena hippurus). Average catches, revenues, routine trip costs, and net operating revenues per boat per trip and per boat per year were estimated for each category of fishing trips. In addition to its descriptive value, data collected during this study will aid in future examinations of the economic effects of various regulations on commercial reef fish fishermen.(PDF file contains 48 pages.)

Techno-economic considerations of shark driftnet fishery, off Lagos coast, Nigeria

Experimental fishing operations with driftnets were conducted in Lagos coastal waters with a view to finding out appropriate gear for effective exploitation of sharks and other pelagic fish species that are not normally caught in trawls. The design and fabrication of the driftnets as well as the fishing trials were undertaken between May, 1977 and April, 1978. Six baited driftnet sets of equal panels with three stretched mesh sizes of 190.5mm; 228.6mm and 241.3mm were used. Analysis were carried out on species composition of catches, weight and number of species/group of fish, catch efficiency of the driftnets as well as on operating costs and financial returns

Fresh and brackish water shrimps of economic importance in the Niger Delta

In the author’s opinion, extremely little is known of fresh and brackish water species, i.e. those supporting the traditional artisanal fisheries and most likely to include suitable candidates for aquaculture. The immediate purpose of this paper is to document the species which are encountered in artisanal fisheries, give available background information on them relevant to fisheries and aquaculture work, and to provide a means for their identification in the field by nonspecialists. Scope of Coverage the "Niger Delta" in the title reflects the geographical area of the author’s personal experience. For purposes of identification, the scope of the paper is West African for brackish species, and Nigerian for freshwater species

Economic analysis of fish import demand in Nigeria

The significance of the fishery industry in the Nigerian economy is examined, considering source of domestic fish production and government fish production programmes and also analysis Nigeria's fish imports during the period 1971-80. Suggestions are made regarding the regulation of fish imports to conserve foreign exchange and the removal of constraints in domestic fish production expansion

Preliminary economic evaluation of 10 metre (LOA) shallow draft vessel in daily fishery, off Imo River, Cross River State

Scientists from the Institute with the collaboration of Food and Agricultural Organisation (FAO), Rome designed and built a 10-m (LOA) shallow draft vessel. The prototype vessel was tried at Uta-Ewa, Ikot Abasi, Cross River State. The paper deals with the preliminary economic analysis of the performance of prototype vessel. An analysis of the annual return has shown that 43.66% of the annual gross income was paid to labour; 15.91% was spent on repairs and replacements; 7.76% on fuel and lubricants; 24.38% on maintenance costs and the return of investment, 6.2%. This low return of investment is attributable to high percentage of labour costs as well as low fishing intensity

Artisanal canoe fishing industry of the Rivers State: its economic viability and investment potentials

Consequent upon the present national call in Nigeria for all to go back to agriculture including fishing, most retrenched workers and unemployed youths from the riverine areas are taking up fishing as a legitimate and gainful livelihood. To sustain this tempo and attract more investment, the economic viability of such projects must be known. This study is an attempt to document the profitability and investment potential of artisanal canoe fishing. Socio-economic information including catches, operational cost and returns were obtained through a personal interview questionnaire survey of 240 randomly selected artisanal canoe fishermen from Bonny, Brass and Degema Local Government Areas (LGA) of the State and analyzed. With an investment cost of about 8,135, 8,490 and 6,571 and operation cost of 750, 776 and 627, the analysis showed an average monthly gross income of 1,869, 3,221 and 1,775 for the three local government areas respectively. A benefit-cost-ratio of 1:8, net present value of 400, 603 and internal rate of return greater than 50% were obtained. Since capital invested in fisheries is not tied up for long before benefits start flowing, coupled with the high IRR, it is concluded that artisanal canoe fishing would be an economically viable venture if well managed

Economic analysis of utilizing Kainji gas kiln for fish smoking in the Kainji Lake Basin of Nigeria

Marketing of smoked fish in the Kainji Lake Basin (Nigeria) has been found to be complex, traditional and inefficient. It is also said to be limited in scope due to poor handling and processing techniques, lack of storage facilities and inadequate marketing informations. The invention of Kainji gas kiln has been found suitable to overcoming poor handling and processing techniques. This paper discusses the feasibility of operating Kainji gas kiln commercially supported with adequate storage facilities and competent management hands. The financial indicators of net present value (NPV), 47,481.11, Internal rate of return (IRR) 24% and payback period of 2.3 years that are calculated confirmed that the commercial use of Kainji gas kiln is indeed profitably feasible

Fish farming in Anambra State: economic criteria

The paper is based on the premise that an understanding of the role and potentials of fish farming entrepreneurs in terms of their activities and expectations would enhance fish production and productivity. To this end, the present paper investigates the activities of 24 fish farmers in Anambra State, Nigeria. Based on the fish farmers' experience, the paper presents fish farming investments, budgets and recommendations that could ensure fish farming development as a profitable business venture and at the same time ensure greater fish production in the country

The economic impact of diseases and parasitic problems in freshwater fish production

Diseases and parasitic problems could constitute significant economic losses in fish production if not controlled, thus the need to continue monitoring its prevalence. Based on field studies on feral and intensively raised fish at the Kainji Lake Research Institute Nigeria, some diseases and parasitic problems have been identified. These include; helminthiasis; fungal disease; protozoa which include Myxosoma sp., Myxobolus spp., Henneguya sp., Trichodina sp., Ichthopthrius sp. bacterial mainly Aeromonas sp., Pseudomonas sp., mechanical injuries; death due to unknown causes and economic assessment of myxosporidian infection. Suggestion for disease control in fish production are recommended
