Captura de tunídeos com vara e isca viva em Moçambique

Included in the project MONAP GCP-MOZ/006/SWE "Fishing development in inland and coastal waters in Mozambique", a tuna fishing experimental program was carried out in coastal waters of Mozambique, using a catching method with rods and live baits. In order to explore this method and demonstrate the collaboration needed, the present paper has been thought for those interested in an overview of the work to be carried out.

Algumas notas sobre a captura e o aproveitamento do tubarão

The abundance of sharks is notable in the waters of Mozambique but this species has never been the object of a dedicated fishing effort. However, in recent years, some fishing activities have been carried out essentially for capture. The present paper describes status and trends of shark fisheries, utilization and trade of sharks. It is based mainly on working notes made by Mr. Tsnetoshi Mihara, a FAO expert involved in the MONAP Project - Development of coastal and continental fisheries (FI -1).

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.

Avaliaçāo preliminar do estado da exploraçāo de Kapenta (Limnothrissa miodon, Boulenger 1906), em cahora bassa com base em dados históricos de captura e esforço de 1995-2000

The fishing of kapenta (Limnothrissa miodon, Boulenger 1906) on the Cahora Bassa Dam started around 1992, when considerable stocks of this species were discovered in the lake. The species is believed to have successful established in the Dam following a natural introduction through a downstream movement from Kariba dam where it was introduced in 1967/68. Fisheries statistics on the kapenta fishery have been collected since 1993 by the Ministry of Fisheries through the Provincial Offices for Fisheries Administration of Tete (SPAP - Tete) but only data from 1995 onward are available on the database of the Ministry of Fisheries and these are the data that was used for compiling the present report on which trends of fishing effort, catch and CPUE are analyzed. Catch and effort have increased with time, from a minimum of the 4 thousand metric tons for an annual fishing effort of 36 fishing rigs in 1995 to a maximum of 12 tons for a fishing effort of 135 rigs while CPUE followed a decreasing trend during the same period. Correlation analysis between catch and effort suggests that probably environmental factors may have influence on catch variation than the increase on fishing effort. Two models were applied for calculating MSY and FMSY resulting in two pairs of roof leading to two scenario of fisheries management. 10137 tons and a FMSY of 177 fishing rigs were computed using Schaefer model while 11690 tons and a FMSY of 278 were obtained using Fox model. Considering the differences between the two results and considering the fact that the two models have no differences in terms of precision and the fact that their determination coefficient are not different it is suggested, using the precautionary principle that result from Schaefer model be a adopted for fisheries management purpose.
