It aimed to provide a forum for presentation and discussion of a wide range of topics relevant to the study of small pelagics, their ecosystem and their fisheries management. The Symposium was split into four main sessions: resources and exploitation - biology and ecology of main resources and status of fisheries; dynamics and variability of pelagic fish populations and environmental influences; methods and models for assessing small pelagic fish stocks; and management of fisheries on shared resources. The Symposium ended with a general discussion aiming to identify specific problems to address as well as providing recommendations on ways forward. The expected outcome of the Symposium was that it would contribute to: the synthesis of existing information; an evaluation of the potential use of this information for shared stocks fisheries management; and the provision of examples and suggestions for possible models and mechanisms for such management. The Symposium was attended by around 100 participants; 43 oral presentations and 30 posters were presented. The Symposium was organized as the closing activity of the project “International Cooperation with the Nansen Programme. Fisheries Management and Marine Environment” (GCP/INT/730/NOR) and was cofinanced by the National Fisheries Research Institute (INRH) of Morocco, which was responsible for the local arrangements. These Proceedings present a summary of the various sessions as well as the outcomes of the general discussion. They also provide scientifically reviewed papers and many of the papers in support of posters presented at the Symposium (non-scientifically reviewed).

The study includes published research on the topic, as well as two interviews conducted with a Paz Martín Lozano, a Spanish politician who is an expert on Saharawi issues, and Jadiyetu El Mohtar, a Saharawi activist and representative of the National Union of Saharawi Women (UNMS) who was well known by the Spanish media due to the hunger strike that she went on at the Lanzarote Airport in 2009. Despite the unbearable extreme conditions, Saharawi people were able to organize their political, economic and social life in refugee camps in the middle of a desert, mainly thanks to the incredible Saharawi women who educate their children to fight for the liberation of the territory of Western Sahara in a peaceful and non-violent way. They are striving for the recognition of the Saharawi cause at the international level and raising awareness of their right to self-determination through a free and fair referendum.

    Travaux du Muséum National d’Histoire Naturelle © 31 août «Grigore Antipa» Vol. LVI (1) pp. 9–18 2013 DOI: 10.2478/travmu-2013-0001 CALOZODION MOYAS, A NEW METAPSEUDID SPECIES (CRUSTACEA: TANAIDACEA: APSEUDOMORPHA) FROM THE MOROCCAN ATLANTIC COAST MOHAMED MENIOUI Abstract. A new apseudomorph tanaidacean species, Calozodion moyas sp. nov., from the Moroccan Atlantic waters is described. The new species is the third species of the genus Calozodion Gardiner, 1973 known in the western African coasts and the tenth in the worldwide fauna. The main features by which the new species differs from all others of the genus Calozodion consist in the presence of a mediodorsale process at the basis of pereopod 2 (absent in C. bacescui Guţu, 1996, C. dollfusi Guţu, 1989, C. heardi Guţu, 2002, C. multispinosum Guţu, 1984 and C. singularis Guţu, 2002) and of five long setae on the first article of mandible palp (comparatively to at most three setae in the species C. dominiki Bochert, 2012, C. simile Guţu, 2006, C. suluk Bamber & Sheader, 2005 and C. wadei Gardiner, 1973). Other differences result from the identification key of the species of the genus Calozodion presented in the final part of this paper. Résumé.

Les principaux caractères par lesquels cette espèce diffère de toutes les autres espèces du genre Calozodion consistent en la présence d’une excroissance médiodorsale au niveau du basis du pereopode 2 (absente chez C.

  • On the Native Status of the Southern Right Whale Eubalaena Australis in Peru
    Boletín del Museo Nacional de Historia Natural, Chile, 58: 75 - 82 (2009) ON THE NATIVE STATUS OF THE SOUTHERN RIGHT WHALE EUBALAENA AUSTRALIS IN PERU Koen Van Waerebeek 1, Luis Santillán1 and Edith Suazo 1,2 1 Peruvian Centre for Cetacean Research (CEPEC- Centro Peruano de Estudios Cetológicos), Museo de Delfines, Pucusana, Lima 20, Peru. e-mail: [email protected] 2 e-mail: [email protected] ABSTRACT The native status of the southern right whale in Peruvian waters is now firmly supported by six confirmed sightings, including four cow-calf pairs, the northernmost at Pucusana (12°29’S,76°48’W) and off San Bartolo (12°24’S,77°11’W). An unconfirmed report exist from northern Peru. Five of six observations were shore-based, underscoring the importance of neritic habitat for E. australis also in Pacific South America. As sighting intervals have shortened over a period of two decades (near significant trend, P= 0.054) without indication of improved reporting, a guarded optimism for the recovery of E. australis in Peru may be warranted. However, a near-collision event with a fishing boat warns of conservation challenges ahead. As applies to three other cetacean species, the coast of Peru is proposed as the most boreal habitual range for E. australis on the planet, enabled by the cooling effects of the strongest of eastern boundary currents. Keywords: southern right whale, northern distribution, Peru, habitat, collision RESUMEN Sobre el estatus nativo de la ballena franca austral en el Perú. El estatus nativo de la ballena franca austral en aguas del Perú está firmemente apoyado por seis avistamientos confirmados, incluyendo cuatro pares de madre-cría.

Zooplankton were sampled using a bongo Cintra Bay; Zooplankton; net, 150 mm mesh size, during two surveys, in autumn 2015 and spring 2016, extending from the coast Copepods; to the open sea. Fourteen zooplankton groups were identified, where copepods represented 49.1% and 92.5% of the total abundance in autumn 2015 and spring 2016, respectively. Tintinnids accounted Diversity indices; Environmental for 39.7% and 4.7%, respectively. The total zooplankton abundance was higher in autumn À3 À3 parameters (55 992 ind m ) than in spring (2123 ind m ). Nineteen species of copepods, belonging to 14 fami- lies, were identified. Euterpina acutifrons and Oithona nana were the most common and abundant species. The Acartiids were represented by three species (Acartia clausi, A. tonsa and A. bifilosa) in autumn and one species in spring (A. clausi). The copepods diversity was significantly different between the two seasons showing high values at the entrance and the center of the bay in autumn 2015 and in the southern half of the bay in spring 2016.
