Form and function of this particular fishnet have not changed since its introduction from Europe after the middle of the nineteenth century. Its survival, now centered in Louisiana, owes much to its suitability to independent, solitary fishermen

Fishing on Sierra Leone's Sherbro Coast is divided into a technology using traditional canoes and simple gear and one with outboard motors and nylon nets. The latter is market-oriented and has brought larger households, dietary changes, and more
The tuna nets of the Gulf of Cadiz were the support for one of the most important fisheries in pre-industrial Europe. The literature describes the fishing methods and the localization of the tuna nets, but does not provide quantitative evidence
of their output. On the basis of a historical record of the bluefin tuna catches, collected in the XVIIIth Century by the house of Medina Sidonia, the AA. have estimated a series of fishing production for the period 1525-1763. Such series shows the secular trend
This study intends to explain fishing space of main fisheries at Choshi Fishing Port, which is one of the leading bases for offshore fisheries in Japan. Fishing space consists of fishing grounds, operating sea areas and headquarters of fishing boats

The spatial structure consists of an inland space, a marine space and a port space functioning as a node to combine the former two spaces. Since these spaces are interrelated or combined by the movement of people or materials, fishers' daily
movement is then examinated. With fishing grounds shrinking in size, those along the coast have become important. Local fishers utilise them, and this has caused fish resource management problems. On the other hand, recreational activities play an important
role in the usage of the port and the fishing grounds.

As well as the development of oil from the 1970s there has been the other major economic innovation of fish farming. The direct employment provided by the oil industry is exceeded by the fish-related industries. The islands have now to look more
to fish-related employment for their future. Fish farming has a notable effect in distributing employment throughout the islands. Fish processing is mainly in central locations.

Assessing potential effects of global climate change on tropical freshwater fishes
Asia ; Biogeography ; Climatic variation ; Ecosystem ; Fish ; Fresh water ; Global change ; Tropical zone
The extreme seasonal fluctuations in discharge of tropical rivers, through the effects on fish habitat availability and habitat conditions, have produced a range in preferred habitat types among riverine fishes. The AA. suggest that initial
assessment of potential effects of climate change on tropical freshwater fishes should focus on changes to water quantity variables in riverine environments.
Bestimmungsgründe und Elastizitäten der Nachfrage nach Fisch und Fischwaren in der Bundesrepublik Deutschland. (The determinants and elesticities governing the demand for fish and fish products in the Federal Republic)
Using a time-series analysis based on the annual overall economic data for the period 1961-1980, a quantification is made of the influence of important economic variables on the demand for fish and fish products in the Federal Republic. (L'A.).
