Avian piscivores: basis for policy.

In Britain, many birds eat fish in fresh waters but only three species, cormorant, red-breasted merganser and goosander, are commonly perceived to present serious problems for freshwater fisheries. Complaints are mainly that cormorants eat large fish and that all three bird species eat so many juvenile fish, that there are subsequently fewer fish to be harvested or angled, but also that persistent predation by birds changes fish behaviour so that they are less 'catchable'. To this end, this report reviews existing information on the current status, foraging ecology, and population biology of the three bird species as background to their potential impact on fisheries. Discusses fish population dynamics within the context of predation effects. Reviews existing experimental evidence for impacts on fish populations and fisheries; and describes current legislation, discusses potential criteria for serious damage to a fishery, and suggests ways forward for NRA policy and research.

Toward a Rational Seafood Trade Policy

With a record trade deficit of almost $146 billion in 1986, and continued high deficits in 1987, there is growing concern about how continued deficits will affect the U. S. economy. Because fishery products had a record $6.3 billion deficit in 1986, the U.S. National Marine Fisheries Service (NMFS) has made the reduction of the fisheries trade deficit one of its top priorities. A recent NMFS trade objective was to "increase exports and domestic consumption of U.S. fishery products" which would lead to a reduction in the trade deficit. In this paper we explore this policy in terms of practicality and desirability.

U.S. Fisheries Management and Foreign Trade Linkages: Policy Implications for Groundfish Fisheries in the North Pacific EEZ

The groundfish resources of the U.S. Exclusive Economic Zone (EEZ) off Alaska, dominated by Alaska or walleye pollock, Theragra chalcogramma, Pacific cod, Gadus macrocephalus, and flatfishes, Pleuronectidae, can sustain annual commercial harvests well in excess of 2 million metric tons (t). As recently as 1979, foreign fisheries took 99 percent of the annual harvest supported by these resources. This has changed dramatically during the 1980's. The foreign fisheries have received rapidly decreasing allocations, first as joint venture fisheries expanded and, more recently, as the domestic fisheries have grown. Joint venture fisheries are fisheries in which domestic fishing vessels deliver their catch directly to foreign processing vessels in the EEZ. By 1986, the joint venture and domestic fisheries accounted for 66 percent and 8 percent, respectively, of the annual harvest. The preliminary corresponding figures for 1987 are 78 and 18 percent.

Os limites da flexibilização e informalidade na produção e trabalho contemporâneos: imigração laboral boliviana e a indústria de vestuário de São Paulo

A migração laboral de bolivianos para São Paulo é um processo intrinsecamente relacionado aos planos de ajuste estrutural ocorridos na Bolívia e no Brasil na segunda metade dos anos 1980 e no início da década de 1990, respectivamente. Para a Bolívia, o Decreto 21.060 implicou a privatização de mineradoras e conseqüentes demissões em massa, além de uma abertura econômica que favoreceu migrações internas para as regiões cocaleiras e para as periferias das grandes cidades. Posteriormente, esses migrantes e seus familiares se destinaram a países limítrofes como Argentina e Brasil. Destaca-se nesse contexto a localidade de El Alto, origem de grande parte dos imigrantes que se destinaram a São Paulo. Do lado brasileiro, houve também uma abertura econômica que foi prejudicial a amplos setores da indústria, como a cadeia têxtil-vestuário. Para reduzir os custos de produção e aumentar sua competitividade em relação às mercadorias asiáticas, a indústria de vestuário se reestruturou defensivamente e subcontratou grande parte de sua produção material às oficinas informais que empregam imigrantes bolivianos geralmente jovens, indocumentados e com baixa qualificação profissional. Nessa pesquisa, relacionamos esse fluxo populacional às transformações estruturais ocorridas nos dois países, destacando as mudanças nas relações de trabalho decorrentes do processo de reestruturação produtiva. Também abordamos as redes de solidariedade desses imigrantes e os meios pelos quais estes vêm revertendo uma inserção na sociedade de destino em que predominam condições precárias de trabalho e habitação, além de uma instabilidade permanente decorrente da irregularidade documental que atinge grande parte desses trabalhadores.

Synthesis of aquaculture policy and development approaches in Africa

The WorldFish Center was tasked to undertake a study to access, collate and develop background materials to produce an internationally linked and Africa-wide perspective on sectorally relevant policy issues. The specific objective of the study was to assess and define conditions and impact pathways, in Africa or elsewhere, where markets, policies, resources and technologies have combined to promote steady and sustainable growth of aquaculture, and where have been clear direct impacts on food supply, income, employment and consumption opportunities, as well as increase in supply that has led to stabilised prices. The study was also aimed at providing guidelines for scaling up the implementation of the synthesis study via Afri-FishNet (CAADP Fish Expert Pools) at the national and regional levels.
