A review of 1973 -1982 tuna fishing activities within Nigeria's eez and the option for Nigeria OceanDocs
Ajayi, T.O..
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.

Caracterización del proceso de descarte de merluza (Merluccius hubbsi) en la flota de buques congeladores y factorías. Resultados preliminares a partir de los datos recolectados por observadores del INIDEP en seis mareas realizadas entre agosto y diciembre de 1995. OceanDocs
Cañete, G.R.; Dato, C.V.; Villarino, M.F..
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...

Dinámica de la flota comercial argentina dirigida a la pesquería de merluza (Merluccius hubbsi) en el Mar Argentino. Periodo 1990-1997 OceanDocs
Dato, C.V.; Villarino, M.F.; Cañete, G.R..
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...

Estratificación de la flota industrial de buques fresqueros y estimación de los rendimientos OceanDocs
Bertolotti, M.I.; Pagani, A.N.; Hernandez, D.R.; Buono, J.J..
In order to increase knowledge about the ice chilling fleet and to explain the relationship between structural variables and yields, a simplified model was developed. The fleet was classified in three homogeneous strata. Stratum I includes the smallest ships, with a catch composition equal to that of the large coastal fishing vessels. The stratum yields decreased in 1997 and 1998. Strata II and III have common hake as the main target of catches. Yields of those strata showed a continuous decrease as of 1994/1995. Therefore, the species was replaced by other fish originally caught by other fleets. These two last strata are more vulnerable to overfishing of traditional coastal and demersal fisheries.

Estratificación y estimación de los rendimientos de la flota de buques procesadores congeladores arrastreros. OceanDocs
Bertolotti, M.I.; Hernandez, D.R.; Pagani, A.N.; Castañeda, M.F..
In order to better understand the behaviour of the trawler processing freezer fleet in the Argentine Sea, an analysis of yields and structural characteristics for the 1989-98 period was carried out. The relationship between structural variables and yield expressed in kilos per day was explained with a simplified asymptotic model. The fleet was divided into four homogeneous strata. Common hake is the target of stratum I and stratum II which are deeply affected by overfishing of the species. As of 1993, in stratum III, common hake was replaced by other pelagic and demersal species, mainly hoki. In fleet stratum IV southern blue whiting and hoki were caught. Catches of the latter increased during the last three years.

General statistics of the French purse-seine fishery in the Indian Ocean OceanDocs
Pianet, R..
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).

Improvements in the Ghanaian tuna statistics system OceanDocs
Quartey, R.; Bannerman, P..
Light fishing operations (LFO) in Ghana is concentrated in the three major coastal municipalities of Greater Accra (Tema), Central (Mumford & Elmina) and Western (Sekondi) Regions; these areas have the port facilities for landing of the catch by the larger inshore vessels that operate the purse seine fishery in Ghana and which predominantly operate the light attraction. Currently there are about 250 registered inshore vessels in the country whose sizes range between 39 – 60 feet , only a small fraction are actually working at the moment due to problems with spare parts and operations. Light attraction is the technique of aggregating fish by artificial light; and light fishing is the process of fishing the attracted fish by hooking, gill-netting or by...

Les Sars Deplodus sargus (Linne 1758) du Golfe du Lion: croissance et caracteristiques des debarquements aux criees de Sete et du Grau-du-Roi. ArchiMer
Man-wai, Rabenevanana; Quignard, Jean-pierre.
Age and growth of seabream D. sargus in the Gulf of Lions (Mediterranean Sea) were examined using scale reading. Growth was expressed by the von Bertalanffy's equation based on the estimation of total lengths at the time of annual ring formation. The growth in weight and the length-weight relationship were calculated for both sexes separately and combined during and after spawning periods. Preliminary investigations on the characteristics of commercial catches (from Sete and Grau-du-Roi commercial fishing grounds) were also carried out.

Relação entre parâmetros ambientais e distribuição temporal de dois pequenos peixes pelágicos Decapterus russelli (Rüpelli, 1930) e Amblygaster sirm (Walbaum, 1792) na Baia de Inhambane, Província de Inhambane OceanDocs
Halare, I. A..
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...
