Distribuçāo e biologia das espécies de camarāo de águas pouco profundas

This study investigates the life cycle of the two major commercial species of prawns in Mozambique - Penaeus indicus and Metapenaeus monoceros - and their prime nursery microhabitats in the mangrove swamps.

História da pescaria de camarāo de águas pouco produndas no Banco de Sofala

This work compiled data and information previously reported on the shrimp fishery and stock, since the beginning of commercial fishery in 1965. It includes a fishery description, the evolution of the fishing effort, landing and catch rates. The main historical management measures implemented in the fishery are also described, which includes the licensing regime, minimum mesh size requirements, closed seasons and total allowable catch. The methodologies used for stock assessment are also presented.

Captura de camarāo de águas pouco profundas e condições ambientais no Banco de Sofala

The present study deals with the performance of shrimp in shallow waters in Sofala Bank presents both seasonal fluctuations as well as fluctuations year to year. These variations may be due to several reasons: abundance of shrimp, fishing effort, fishing techniques and environmental conditions such as the turbidity of the water, tides, temperature and salinity.

Alternativas de gestāo da pescaria de camarāo de águas pouco profundas

The shallow-water shrimps represent the most economical resource in Mozambique. Therefore, annual surveys have been carried out to investigate the state of the stock, the fishing methods for a better analyses catch/effort statistics. Resource assessment was conducted on principal species - Metapenaeus monoceros and Penaeus indicus - to estimate levels of abundance and distribution in the Sofala Bank.

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.

Relatório do cruzeiro realizado no Banco de Sofala no barco "Meleia" em Agosto de 1981: camarāo de águas pouco profundas

The geographic and bathymetric distribution of the shrimps Penaeus indicus, Metapenaeus monoceros, P. japonicus and P. monodon along the coast of Mozambique are given. Biological data of the main species P. indicus and M. monoceros are presented.

Recursos de atum nas águas de Moçambique

From 1976 to 1979 tunas of Mozambique were studied for about 40 months using seven research vessels. The main purpose of survey was not to study these resources therefore part of the information is poor and incomplete. During these three years, there were about fourteen months for experimental logline fisheries of deep-water tunas. This work corresponds to a bilateral cooperation program with USSR.

O recurso de camarāo de águas pouco profundas

The shallow-water shrimp lives along the coast of Mozambique. Its distribution is closely linked to the existence of mangroves, where it grows during the first months of life. The adult population live in the bays or offshore, in shallow waters. A description of resource distribution, fishing areas and catch composition is given.

Informaçāo geral sobre o manancial de camarāo de profundidade e a sua exploraçāo nas águas da República Popular de Moçambique

The deep-water shrimp were already studied many years ago, but their commercial fishing on large scale, only developed from the seventies. Two Luso-U.S. fishing companies (1966), and a Luso-South African company (1963- 1968), dedicated to the fishing of deep-water crustaceans, including Haliporoides triarthrus species (Araújo, 1973). Also Champion (1973) described commercial catches of Plesiopenaeus edwardsianus, Aristaeomorpha foliacea and Haliporoides triarthrus in the waters of Mozambique. The first Spanish vessels began fishing activity in 1968 (Freitas and Araújo, 1973) but all of these companies captured mainly penaideos on the continental shelf.
