Estimativa da captura total de peixe e camarão das pescarias de emalhe e de arrasto da Baía de Maputo, em 1985

The most important fisheries of Maputo Bay (Mozambique) are the gill netting of the Hilsa kelee and the trawling of the shrimps Penaeus indicus and Metapenaeus monoceros . Data of capture and yields are presented and the number of artisanal fishing boats and semi-industrial fishing vessels is given.

Análise de dados colhidos a bordo da embarcação Cassiopeia de 7 a 15 de Maio de 1999

This paper aims to analyse the results of a cruise aboard the vessel Cassiopeia, held from 7 to 15 May 1999. These results relate mainly to the Quissico area and have as an objective to verify different features: total fish catch, predominance of caught species, dimensions of captured fish and fishing effort.

Compilaçao de dados sobre fauna acompanhante do camarão em Moçambique

All the data that the Instituto de Investigaçā Pesqueira was able to collect relating to by-catches of shrimps are presented. The by-catches of shrimp are almost entirely comprised of fish with commercial value. In this paper the author analyzes data for areas separated according to yields obtained.

Análise dos efeitos económicos das opções de gestāo da pescaria de camarāo de águas pouco profundas

The paper deals with the proper management of fishing resources of shrimps in shallow waters, those currently constitute the main source of foreign currency trade of the country. The analysis of the level of the productive sector is presented by the local Institute of Fisheries Research.

Análise dos efeitos da introduçāo de medidas de gestāo na pescaria de camarāo do Banco de Sofala

Biological effects of management measures introduced in the shrimp fishery from 1985 to 1990 are analysed as well as the results from simulation of different closed seasons. Observed changes in recruitment, total catch, biomass and average individual weight during 1985 to 1990 for Penaeus indicus and Hetapenaeus Monoceros are also analysed. Further studies on a stock-recruitment relationship are important due to decline of recruitment levels in this period. A three-month closed season starting in January is recommended, without increases in the monthly fishing effort. The TAC shall be fixed according to the recruitment level each year.

A fauna acompanhante de camarāo no Banco de Sofala: análise preliminar

An estimation of the total industrial catch of the shallow water shrimp by-catch for the period 1986-1990 is presented. By-catch species compositions based on landings and onboard samples at ex-Emopesca/Beira (Marbeira) and Pescamar are also presented. The by-catch is essentially composed by 2nd and 3rd commercial fish categories, other crustaceans and cephalopods appearing in varying proportions in the catch. The total catch of shrimp by-catch estimated for the period is approximately 17 to 25 thousand tons per year.

Ensaio sobre a forma de comunicaçāo dos resultados da investigaçāo de recursos pesqueiros à administraçāo pesqueira. Tema 1: Síntese dos resultados e métodos de análise utilizado na avaliaçāo do recurso de camarao de águas pouco profundas do Banco de Sofala.

The main goal of this paper is to provide samples of fishing methods analyses applied to studies on shrimps stock assessment in the Sofala Bank. Especially the authors provide the administrators with the main limits of application of described methods.
