The present paper deals with a dynamic reaction model of a fishery. The dynamics of a fishery resource system in an aquatic environment consists of two zones: a free fishing zone and a reserve zone. To protect fish population from over exploitation, a control instrument tax is imposed. The existence of its steady states and their stability are studied. The optimal harvest policy is discussed ne...
1 This paper is prepared for an internship program under the project of China Fishery Policy and WTO Accession/Implementation collaborated by the Chinese Academy of Fishery Sciences (CAFS) & the Centre for Trade Policy and Law (CTPL), Ottawa, Canada and financed by the Canadian International Development Agency (CIDA). The author wishes to acknowledge Wenguo Cai, a senior research associate at C...
Quantitative analyses of the pink shrimp (Farfantepenaeus brasiliensis and Farfantepenaeus paulensis) fisheries were carried out using data collected from July 1999 to July 2001 from the trawling operations of the fishing fleet based in Santos/Guarujá, SP. According to classical models, the fishery is at its maximum sustainable yield. Therefore, reduction of the fishing effort and adequate seas...
I wish to inform you of the release of the draft 'Western Rock Lobster Fishery Ecological Risk Assessment 2005 Report – July 2005' for a three-week public consultation period. Please find attached the report for your consideration. This report provides background on the western rock lobster fishery, its governance, the reporting requirements for the Ecologically Sustainable Development process ...
Regional tuna fishery management organizations cannot provide specific advice to local fishery managers in small island jurisdictions. The State of Hawaii maintains time series of yellowfin tuna catches dating back to 1949, but these data have never been formally applied to evaluating the effects of the yellowfin fishery in the Main Hawaiian Islands on the local stock. I develop a new approach ...
We consider the potential for using prices as leading indicators of changes in stocks and yields in the freshwater capture fishery in Lake Victoria. Fertilizer run-off from agricultural land is a major cause of nutrient loading, along with soil erosion, atmospheric deposition, and point pollution from industrial and domestic affluent. The interactions between fertilizer applications, water qual...
Using two unbalanced panel data sets of vessels over the periods 1990-1996 and 19942000 the paper estimates stochastic production frontiers and evaluates the effects on individual technical efficiency of inputs controls in the northern banana prawn fishery of Australia. The results indicate that technical efficiency is decreasing in the gear input headrope length that was restricted until 1993 ...
This paper models fishing trawler scheduling for integrated fisheries. Fishing trawler scheduling is a well known problem in the fishery industry. The scheduling problems faced by the fishery industry are more complicated than the traditional merchant trawler scheduling problems. The factors that influence the scheduling of fishing trawlers include catch capacity, processing capacity, etc. We d...
Bonefish, Albula vulpes (L.), support an economically important recreational fishery in southern Florida, USA that has received little scientific study and has never been adequately assessed. A mail survey of 322 captains that comprise the southern Florida bonefish charter fleet was conducted to acquire a baseline understanding of the primary fishery statistics. The response rate was 59% and a ...
