| Examination of published information on temperature, oxygen and other environmental preferences of tuna and tuna like fishes suggests that the Nigerian EEZ should have commercial quantities of the fishes. ICCAT historical catch and effort data analysed are confirmatory. Given the prevailing low level of maintenance consciousness, initial investments and skills required, purse-seine may not be decidedly superior to pole and line as the capture technique. Preferred sizes of vessel type and gear specific scenarios are described. It appears that fuel cost can attract some of the multinational fleets to Nigeria and that transhipment facilities and a local cannery are advantageous. |

| Pursuant to SAGyP resolution No. 814/93, during August-December 1995, six INIDEP Fishery Observers trips on board of processing vessels of the Argentine fleet were carried out. They represented 256 navigation days, 232 effective fishing days, 725 fishing trawls and 2,245 trawling hours. Data measured on board were compared to those reported in the fishing log corresponding to the same cruise and submitted to the DNPyA by the Skipper. Catches observed and reported differ by 3985,7 t (28.2. ), with a maximum difference of 1,200 t in a single cruise. In the case of trawling hours, an important fluctuation of values was observed and, in two cases, the number of hours declared exceeded those actually performed (111 and 72). In the other four cruises, between 3... |

| Since 1990, the Argentine commercial fleet directed to hake (Merluccius hubbsi) has obtained more than 70 of catches South of 41°S while to the North of this latitude the activity concentrated between 39°S and 41°S Argentine Sea, SW Atlantic. Bearing in mind the different characteristics of ice-chilling and freezer fleets, their activities were analyzed separately. Considering the relative percentages of catches declared in fishery statistics, the dynamics of each fleet is described per quarter and year. Special reference is made to 1997 when a closed area to protect juveniles was introduced between 44°S-47°S and 62°W-65°W. The freezer fleet activity, concentrated South of 41°S, especially South of 43°S, was stable throughout the period. It grouped around... |

| This document presents a brief summary of the main general French purse-seiners activities in the Indian Ocean since the beginning of their fishery in 1981: catch by species and fishing type (log and free swimming schools), effort and sampling for sizes and species composition. The description of statistics gathering, sampling and processing procedures are reported in a specific document presented at the meeting (WPDCS/99/09). |

| Catch statistics and fishing craft statistics are presented for the Indian Ocean tuna fisheries for the period 1990-1999. The former are presented by species, country, year and by gear. Details are also given of the number of fisheries crafts in the national fleets, in order to provide information on the economic and technical development of the fisheries and to provide an approximate idea of fluctuations in fishing effort. |

| A distribuição temporal dos pequenos peixes pelágicos Decapterus russelli (carapau do Índico) e Amblygaster sirm (sardinha manchada) foram estudados com base nas capturas e rendimentos da pesca artesanal (arrasto para praia) obtidos no período de 1999 a 2006 na Baia de Inhambane, sul de Moçambique. Foi feita a associação da ocorrência mensal destas espécies com diversas variáveis meteorológicas, nomeadamente: a temperatura do ar, pluviosidade, força e direcção do vento. No período de estudo foram desembarcados na Baía de Inhambane 11.064 t de pescado sendo 1.628 t (14,7%) de Decapterus russelli e 929 t (8,4%) de Amblygaster sirm. A análise estatística caracteriza o clima da Baia de Inhambane em quatro categorias: no primeiro trimestre o clima é... |
