A new species of Euprognatha Stimpson, 1871 (Crustacea, Brachyura, Inachoididae) from off coast of northeastern Brazil Pap. Avulsos de Zool. (São Paulo)
Santana,William; Tavares,Marcos.
A new species of Euprognatha Stimpson, 1871 from off coast of Brazil (Canopus Bank, 02º15.3'00"S - 38º16.0'00"W) is described and illustrated, namely Euprognatha limatula n. sp. The new species is compared to its congeners. Lectotypes are designated for E. acuta A. Milne-Edwards, 1880 and E. granulata Faxon, 1893. A key to the species of Euprognatha is provided.

Biologie et exploitation de l'araignée de mer Maja squinado Herbst en Manche Ouest ArchiMer
Le Foll, Didier.
The aim of this work, which was done as a Doctorate of Philosophy (Phd), was to collect the information necessary to help improve the management of the western Channel spider crab stock. The fîrst section présents the main aspects of spider crab population biology. As well as contributing our own results on spider crab habitat, stock density, démographie structure, growth and mortality estimâtes, migrations, reproduction and recruitment, a synthesis is included of the existing scientific literature. The second section on exploitation covers various features of the fishery : its history, fishing methods, fleet structure, spatial and seasonal distribution of fishing efforts in 1986, trends in the landings, fishing effort and catch per unit effort,...

Contribution à l'évaluation et à l'évolution de la puissance de pêche des fileyeurs français ArchiMer
Morizur, Yvon; Carn, Nolwenn.
En l'absence de données fines sur l'effort de pêche des fileyeurs, on prend couramment la journée de pêche comme unité d'effort. C'est le niveau disponible pour tous les bateaux. Lorsque l'on prend la journée de pêche comme unité d'effort dans le fileyage, l'on se réfère à une unité de temps qui comporte des opérations de levage et parfois de filage et de levage, et la puissance de pêche dépendra principalement des quantités de filets levés, la durée d'immersion étant un facteur peu variable dans une même pêcherie. Cette étude vise à étudier l'influence de ce facteur sur la puissance de pêche et à étudier le lien avec des paramètres physiques connus. Les analyses effectuées montrent que, pour les années 1996-97, les quantités de filets sont dépendantes de...

Etude préalable à la gestion des stocks de crustacés en Bretagne ArchiMer
Autissier, Isabelle; Coum, Andrée; Cuillandre, Jean Pierre; Veron, Gerard; Latrouite, Daniel.
At the end of the seventies, as fishing abundance (based on Catch Per Unit Effort) in crabs and lobster fishery steadily declined, operating expenses increased, and fishing boats changed strategy (changing metiers, covering larger distance to fishing areas, fishing seasons being extended, ...) professionals and scientists aimed to consider reinforcing management measures. To enlighten and support potential related decisions, the Comité Régional des Pêches et Cultures Marines de Bretagne (Regional Committee for fishing and farming in Brittany), together with the ISTPM (Ifremer since 1984), conducted a survey on the exploited populations and gave a review of the involved Breton fleet. This report shows the results of a survey conducted among fishermen,...

Feeding habits of the spider crab Libinia spinosa H. Milne Edwards, 1834 (Decapoda, Brachyura) in Ubatuba bay, São Paulo, Brazil BABT
Barros,Samara de Paiva; Cobo,Valter José; Fransozo,Adilson.
The main goal of this study was the identification of the items of the diet of the L. spinosa, based on the stomach contents analysis. The crabs were obtained from Ubatuba region north-eastern shore of São Paulo State. In the laboratory, all the individuals were dissected, the stomach was retreated and fixed in 10% formaline. The alimentary items were identified under stereomicroscope and analysed by the method of Frequency of Occurrence. A total of 194 stomachs was analysed and nine alimentary items were obtained. Unindentified material was found in 98% of analysed stomach and poriferan were present in less then 1% of stomachs. These results pointed a diversified diet explored by this crab, as well as the employment of some different methods for food...

Relations biométriques chez l'araignée de mer Maja squinado : longueur de référence, distinction juvénile-adulte, taille-poids. ArchiMer
Le Foll, Didier; Latrouite, Daniel; Noel, Philippe.
For the analysis of spider crab populations it is necessary to split the size composition by sex and between age groups, and to convert length to weight. In some cases different length measurements need to be correlated in order to compare the results from different authors. Morphometricaly it is easy to use the abdominal flap to distinguish between male and female, and between immature and adult females, but for immature and adult males it is necessary to use Somertons method to analyse the relation between carapace length and claw width. The relation between carapace length and weight is normally established at moult stage 4, and it obtained separately for males, females, immature and adults spider crabs. When measuring carapace length the present length...
