Description : The Sargassum seaweed [Sargassum natans and S. fluitans] can be classed as a perennial invasive weed problem in all the Caribbean islands. It has been shown to affect fisher-folks, sea bathers, and tourists. It is proving to be costly to remove; in addition to its offensive odour which hampers the clean-up operations. The University of Trinidad and Tobago at the BAFT campus is engaged in series of activities to find suitable uses of the seaweed as animal feed, and as soil medium and ameliorant. This study aimed at evaluating the suitability of the seaweed as a growing media for the production of sweet peppers [Capsicum annuum var. annuum] using different percentage of the weed (0, 25, 50 and 100%) with soil under greenhouse conditions. The crop growth and development and yield were monitored. The results indicated that the plant height [Y pl ht = 16.6 + 0.3 DAT - 0.11 TRT] and leaf number [Y no.lvs = 0.90 + 1.04 DAT - 0.206 TRT] increased as age of the crop increased, but decreased with the increase in percentage of seaweed/ soil mixture. A similar response was observed for the flower buds and fruits numbers and percentage soil mixture. The medium had no effect on the crop transpiration and net photosynthesis rate [PN] , photosynthesis active radiation[PAR] , and stomatal conductance. A nutrient analysis of the medium was also conducted.

Résumé : Oceanic larvae of the European (Anguilla anguilla) and American (A. rostrata) eels have to cross the Atlantic Ocean from the Sargasso Sea to European or North American coasts before entering continental habitats. In some European rivers, eel recruitment is now < 1% of levels in the 1980s. A better understanding of the effects of anthropogenic pressures and environmental fluctuations on eel larvae and subsequent recruitment is a prerequisite to build efficient management plans. The present paper provides insight into the critical oceanic phase of the eel life cycle with a focus on the duration of the larval migration whose estimates varies between 7 months and more than 2 years in both species. Does this range correspond to a natural variability in larval duration or does it stem from methodological artefacts? We first review the different methods used to estimate the duration of larval migration and critically describe their possible sources of misinterpretation. We then evaluate the consistency of these methods with the current knowledge about the ecology and physiology of eel larvae and the physical oceanography. While a moderate discrepancy in migration duration was found between methods for the American eel, the discrepancy was large in the European eel. In this species, otolith microstructure studies indicated migration durations between 7 and 9 months, while other methods pointed to durations of about 2 years. We show that estimates in favour of a long migration duration seem more robust to methodological caveats than methods estimating short durations of migration.

Résumé : Suite au Sommet de Rio en 1992, des réflexions ont abouti à la mise en place de nombreux programmes (nationaux et internationaux) concernant l'étude des milieux modifiés par les actions anthropiques. Parmi eux, le programme national "Dynamique de la Biodiversité et Environnement", auquel participe le laboratoire DEL/Ecologie du Centre IFREMER de Brest, se penche sur le problème des espèces proliférantes en milieu terrestre et marin. Dans ce deuxième cas, les exemples sont peu nombreux mais on citera tout de même les proliférations provoquées par un déséquilibre du milieu (marées vertes (ulves)) et celles dues à l'introduction volontaire ou accidentelle d'espèces (sargasses, caulerpes, crépidules). Crepidula fornicata fait ainsi l'objet d'études particulières de la part du laboratoire d'écologie benthique. Cette espèce présente en effet des potentialités impressionnantes de colonisation de toutes sortes de milieux (baies, estuaires, secteurs conchylicoles) provoquant des déséquilibres dans les écosystèmes envahis. Le programme a donc pour objectifs l'identification du processus de colonisation (incluant l'évaluation de la responsabilité de l'Homme), l'étude des effets sur les populations voisines, et la caractérisation des interactions entre la crépidule et les mollusques filtreurs exploités.
