Pesca de pequena escala em Moçambique: possibilidades de desenvolvimento

The small-scale fishery is a traditional activity and enrolled in social and cultural practices of the coastal communities and some places of the inland waters of Mozambique. Scope for development, major constraints in the small-scale fisheries and best practices are examined.

Pesca de atum no indico: seu desenvolvimento recente e consequências para os Países da Subregião Sul Ocidental

In this study the author provided a synthesis of the most relevant aspects of fisheries in Mozambique and Indo-Pacific Region, discussed at the “Seminario sobre avaliaçāo de mananciais de atum na regiāo indo-pacifiqa-jacarta” held in Jakarta from 20 to 22 August 1984. Tens of documents belonging to the Department of Documentation and Information of the Fisheries Research Institute of Maputo and containing valuable information on the tuna fishing in Indo-Pacífic Region were studied in preparation of this seminar.

Actividade de pesca de emalhe e de arrasto na Baía de Maputo em 1984

The main goal of this paper is to determine the total catch of fish and shrimp made by driftnet fleet and trawling in Maputo Bay in 1984. This estimate is rather primitive in relation to artisanal fisheries. Fishermen show a lack of motivation for registration and data transmition (mainly due to a lack of mobilization and awareness). Then the quality of data is low and the informative system is not effective. The study is based on records of several organizations (Sulpesca, the Maritime Administration of Maputo, Maputo Fisheries Service) and enriched with information collected by samplers of the Instituto de Investigação Pesqueira of Maputo.

Avaliação dos consumos de materiais estratégicos para a conservação dos engenhos de pesca artesanal de Moçambique e Estudos de constituiçāo tipologia e distribuiçāo de alguns engenhos de pesca artesanal de Moçambique

This technical report comprises two different studies in terms of their conclusions, but based on the same field surveys: “Yearly consumption evaluation of the strategic materials for the artisanal fisheries of Mozambique” and “Constitution, typology and distribution studies of the Mozambican artisanal fishing gears”. In the first of the above studies, the amount of the materials found in each gear, the number of such gears and the wear factor “r” are subject to a computed data processing, producing the following outputs: list of materials demanded in each Mozambican fishing relevant province; list of materials demanded in the whole Mozambican territory. In the second study the observed gears constitutions are analysed and differences and similitudes among them are searched. The details of maneuver and productivity are referred as well. Attention is drawn to the fact that observations did not take place on the whole Mozambican territory, even not in the most representative but in some considerably important fishing centers with reasonable safety and connection facilities. About the first study, when it was not possible to reach such considerably important centers the determination of the approximate picture of them has been achieved by verbal information of people knowing them very well and by the sources referred here in after. Concerning the second study inferences have not been made. Although a limited number of samples has been collected, the accuracy of it has been checked by inquiry. Speculations have been developed only on observed cases. The surveys have been made by a team, assigned by the directors of UD-PPE and Equipesca, under author’s coordination.

Fichas analiticas dos equipamentos de pesca

The cards reproduced herewith are the direct result of the field surveys and have been the basic documents for the computed yearly strategic materials needs evaluation. They are presented due to the fundamental role played by them and due to their helpfulness regarding different nature studies, such as investment and maintenance costs determination, in terms of imported materials of the artisanal fishing gears of Mozambique.

Pesca experimental de corrico na zona sul da costa de Mocambique

Based on the proven existence of large pelagic fish resources in the southern coast of Mozambique, an experimental fishing trolling program has been designed to study the possibility of resources exploitation through the introduction of trolling technique on artisanal vessels (Project FAO/TCP/MOZ/5653). Although operational problems occurred, the program carried out during the year 1957, provided a collection of data and knowledge. It allowed the preparation of present paper, which could serve as an indicator for a possible implementation of this fishing method in the Mozambican artisanal sector. Sharing this study, the author expects to give a further contribution to the development of a greater pelagic fishery in the waters of Mozambique.

A case study on the impact of industrial effluent disposal on the fishery of Amba River estuary, Maharashtra

The impact of waste discharge on fishery resources is a matter of great concern. The accepted norm in all environmental impact assessment studies is to avoid areas of high fishery potential while locating a marine outfall. Contemplating on this aspect a case study was conducted in the Amba River estuary before and after the establishment of a petrochemical complex at Nagothane. The treated wastewater from this complex is released through a subsurface outfall after adopting effective control measures for marine disposal of waste. Experimental trawling was done at five locations covering a distance of 30 km during 1990 to 1991. The catch rate within the estuary varied from 0.6 to 255 kg/h (av 24 kg/h). The trend indicated considerable decrease in fishery potential from the mouth of the estuary (av 64 kg/h) to the upstream location (av 11 kg/h). A total of 49 species of fishes, 16 species of prawns, 7 species of crabs and 1 species of lobster were identified from the collections. Number of species gradually increased from the interior segment at Dharamtar (8) to the outer area near Revas (18). A comparison of the quantitative and qualitative nature of the post outfall and pre outfall data revealed only marginal difference. The study indicates that if necessary precautions are taken to render the waste harmless the marine ecology will hardly be affected.

La pesca costera en la Argentina

Se aborda el estudio de la pesca costera en la Argentina (océano Atlántico sudoccidental) teniendo en cuenta los factores económicos, sociales y políticos que promovieron su retraso o desarrollo. Para comprenderlo se analizan las diversas etapas históricas desde la época de la conquista (1580) hasta nuestros días. Se detalla sobre la actualidad de las artes de pesca en pequeña escala, las características de los pescadores, el manejo de las pesquerías costeras y el conflicto por los recursos y perspectivas.

Caracterizaçāo da pescaria de camarāo nos portos de Angoche, Quelimane e Beira, referente ao sistema de pesca

The paper presents the results of a survey carried out in the water of Angoche, Quelimane and Beira referring to the fishing methods used to catch shrimp in the Sofala Bank.

A pesca do atum no Oceano Indico do sudoeste

The tuna species of greatest interest to the countries of the southwest region of Indian Ocean are described. They are called mermas, small "coastal tunas". These fishes need a lot of food and oxygen, but have a limited tolerance for temperature variations. These are features commonly used in determining the possible areas of occurrence and also the most suitable type of fishing gear.

Avaliaçāo do estado dum recurso e da pesca

One of the key sectors of fisheries research is assessment and exploration which should have as main goal the support to the fishing industry: analyzing the effects of fishing on stocks, determining the potential stock to be exploited and the formulation of rules for an appropriate exploitation and preservation of resources. In this paper the author intends to analyze some aspects of the investigation in support to fishery management.
