沈家门是我国近海最大的渔港,沿海六省二市都有渔船在这里停泊、避风、维修、补给和处理鱼货。春夏汛期,停泊在港内的渔船约3,000艘左右,渔民达四、五万人。冬季带鱼汛来港船只有7,000余艘,渔民达十余万人。还有商船和其他各类船只在港内停泊。 1980年,沈家门渔港被列为全国重点渔港,成立了渔港监督机构。普陀县政府对渔港管理工作十分重视,于1981年制定颁布了“沈家门渔港港章”并成立了沈家门渔港综合治理办公室,由县渔委、渔政、渔监、公安、工商行政管理、港监、水产等七个部门组成。在渔 相似文献

渔港是渔船、渔民远航归来,进行避风、修整、补给、交易的“家”,是渔业生产赖以生存和发展的重要基础设施,即使是在发达国家和地区,如挪威、日本和我国香港等,也都给予渔港建设和管理以足够的重视和支持。改革开放以来,港口、岸线对国民经济发展所具有的促进作用B益凸显 相似文献

The Gulf of Finland is one of the most eutrophic areas in the Baltic Sea and is also the main fishing area for more than 150 000 recreational fishermen in Finland. The findings of a mail survey showed that the most important species for the recreational fishery is perch, Perca fluviatilis L. There is no clear evidence that eutrophication has had a harmful effect on the stocks of perch and other species considered important. Heavy fouling of gear, particularly gill nets, is the most acute problem caused by eutrophication to the local recreational fishery. The rapid fouling of passive gear was experienced by 67–86% of all fishermen in the three study areas. A general deterioration in water quality was perceived because only 2–14% of fishermen rated the water quality as excellent. However, a minority of recreational fishermen seem to have adapted or grown accustomed to the deterioration in water quality. Even in the two most eutrophic study areas, 23–31% of recreational fishermen considered that an improvement in local water quality would not benefit their own fishing in any way. 相似文献

This paper focuses on the consequences of a geographical differentiation in reproductive potential through a species range not being recognized in the management of a coastal fishery resource. A dynamic spatial model with age-structure and bioeconomic components was built to explore the potential effects of fishing port location on metapopulations with a source–sink structure. Management of this type of fishery using marine protected areas (MPA) with or without considering the location of source and sink components is also addressed. An array of unit areas for a multi-age semi-sedentary resource was fed with recruits generated by a Beverton–Holt spawner–recruit relationship driven by the adult biomass in a source area. This contributes recruits both to source areas, and adjacent sink areas which do not produce recruits. Recruits are allocated to unit areas in the array according to a negative binomial distribution, allowing age structures to build up in each. Exploitation is from one of two ports, either situated close to the source area or distant from it; it being assumed (as for inshore fleets) that distance traveled is a key variable. Effort exerted per unit area is therefore determined by dynamic site-specific profits. Because fishing costs increase with distance, the alternative port locations are predicted to have substantially different impacts on biological and economic performance variables when there are no spatial management measures in place. Closing half the source area to fishing mitigates substantially the effect of port location, and improves all performance variables regardless of port location. The greatest positive impacts of a closure occur where the main port harvesting the resource is the one nearest the source area being protected.
When a spatial closure is applied, the average distance harvesters travel from a port close to the source is predicted to increase for all levels of fishing intensity, while distances traveled by fishermen from a port near the sink areas are predicted to decrease. If an MPA is established outside the source area, it is predicted to result in deteriorating production and net revenues because fishing intensity will tend to increase in the unrestricted source area. 相似文献

Effects of intensive fishing on the perch population in a large oligotrophic lake in eastern Finland
The perch population in Lake Höytiäinen was intensively fished to reduce the density of the population and hence also the predation pressure by perch on vendace larvae. A hypothesis suggests that this predation can prevent recovery of commercially important vendace stock from a state of low-density. In the 1990s the density of the perch population in Lake Höytiäinen has increased, while the vendace stock has been sparse. Intensive fishing was conducted by professional fishermen with a paired bottom trawl, seine net, hoop net and small fish traps and by recreational fishermen with small fish traps. The size of perch population during the intensive fishing period was studied by test fishing with multi-mesh gillnets and the Leslie method in which trawl YPUE was regressed on the cumulative yield. The results suggest that the population size clearly diminished in the area where the fishing pressure was strongest. YPUE of test fishing decreased ca. 30% whereas the Leslie method gave almost a decrease twice as large as that of the former. Mean weight of perch increased in the trawl and test fishing catches during the intensive fishing period. The most effective fishing gear was trawl (62% of the total yield), but importance of trap net fishing by recreational fishermen was also high as they caught 22% of the total yield. 相似文献

Developing co-management in an artisanal gill net fishery of a deep hydro-electric reservoir in Sri Lanka 总被引:1,自引:0,他引:1
Abstract Victoria, is a recently (1984) impounded, deep, hydro-electric reservoir in Sri Lanka with an established commercial fishery. Participatory appraisal of the fishing community revealed decreasing reliance on fishing income with many fishermen moving away to supplementary occupations because of declining fish catches. Illegal fishing and theft of fishing gear resulting from open access, difficulties encountered in enforcing fisheries regulations and the need for fishermen to find alternative sources of income during low water levels are the major management problems. The top–down centralized management approach previously practised was ineffective in addressing any of these issues. Therefore, the possibilities and limitations for introducing co-management as an alternative management strategy were discussed. Financial hardship coupled with perceived benefits through state sponsored welfare schemes caused a positive attitude change among fishermen, making them respond favourably to fishery management. Establishing a licensing system for controlled access, ensuring greater user-group participation through equitable distribution of state sponsored benefits among members, attempting to enforce penalties for illegal fishing linked with surprise checks to enforce management regulations, and obtaining stakeholder perceptions regarding management issues are some of the recent steps taken by the Fishermen's Co-operative Society which would positively contribute towards developing effective co-management in this reservoir. 相似文献

Recreational fishing, whether free or at cost, has an economic value. This value was measured in five Nordic countries based on a contingent valuation mail survey. Regression models were used to identify demographic characteristics, types of fishing patterns and differences in the countries’ management regimes that can explain both actual fishing expenditure and willingness to pay for the non‐market benefits by persons participating in fishing or enjoying the benefits derived by it. Net benefit, i.e. willingness to pay over and above actual expenditure was highest amongst those fishing. In Denmark, the small number of generalist fishermen get the highest benefit. In Finland results are mixed but sports fishermen benefit on average even more than generalists. Urban sports fishing raises the highest benefit in Iceland while in Norway the benefit is more equally spread, with occasional anglers and women reaping the least. In Sweden the mean benefit is the lowest in the Nordic countries but evenly distributed among categories of fishermen. In the Nordic countries combined, nationality explains willingness to pay as being Norwegian or Finnish increases benefit and being Icelandic reduces it. The non‐use value of recreational fisheries was elicited through posing questions on willingness to pay for the preservation of the existence of current fish stocks and current quality of recreational fishing to persons participating in fishing or enjoying the benefits derived from it. For those not fishing or people in general, the power of the models to explain willingness to pay for the existence of recreational fisheries was very weak. The benefit, i.e. willingness to pay, is higher if somebody in the household fishes. Educated, young, urban, well‐off citizens also put value on the non‐use of the resource. 相似文献

改革开放以来,随着渔业经济的快速发展,我国的渔业发展面一临着渔业资源严重枯竭、渔业监管困难、渔民收入增长幅度放缓等诸多问题。为此学术界在渔业资源管理方法上提出了许多意见,同时也存在着一些分歧。文章通过理论推演,结合文献数据,探讨了渔村社区组织与我国渔业协会的关系,分析了包括渔业协会在内的渔村社区组织对渔业资源管理的作用,通过对代表性渔业资源管理理论的利弊分析,剖析了渔民协会等渔村社区组织的渔业资源管理职能。同时指出由于渔业协会在资源管理中具有重要作用,但因其自身也存在着一定局限性,因此,培育渔业协会、完善其资源管理职能,实行基于渔业协会等渔村社区组织的合作管理也就成为我国加强渔业资源管理的一种制度选择。 相似文献
