| Age is a necessary parameter used in population dynamics to assess the state of exploited resources. This parameter is poorly known for most deep-sea species (depth > 400 m). This work focused on age estimation from otoliths of Alepocephalus bairdii (Alepocephalidae), Coryphaenoides rupestris (Macrouridae), Helicolenus dactylopterus (Sebastidae) and Hoplostethus atlanticus (Trachichthyidae), which French fishery exploitation, off the west coasts of the British Isles, began the late 1980's. Considering otolith growth zones as annual, the four species all show high longevity: 38, 54, 43 and 130 years, respectively, together with slow growth. The differences in growth between sex were estimated and difficulties in accurately estimating the age were... |

| The authors have studied the structure of the fishing fleet for artisanal and industrial fisheries and its activities in the harbours of the Atlantic coast: Douarnenez, Concarneau, Lorient, Saint-Nazaire, Nantes, La Rochelle, Bayonne etc. It appears that the decline of the traditional fishery corresponds to the degradation of the stocks, especially the hake and megrim stocks. The industrial fishery supports the consequences of this overfishing while the artisanal trawling fishery showed in 1975 a relative prosperity. In conclusion, it is evident that stock degradation is chiefly caused by fisheries utilizing too narrow meshes. This is not irreversible and it is probable that a sensible widening of the meshes would permit better management of the potential... |

| Following the mass mortality of Ostrea edulis, some experiments were conducted with O. chilensis broodstock and spat coming from Chiloe Island (Chile). Concurrently, spat of th same species produced in a hatchery was cultivated. After a small period of growth, these oysters died during the summer. Microscopic observations showed Marteilia refringens and Bonamia ostreae in the oysters' tissue. For these reasons, Ostrea chilensis has not been retained to temporarily replace O. edulis. |

| The methane concentrations within both Holyhead Harbour and Western Irish sea sediments were consistent with the hypothesis that methane was the major component responsible for the acoustic turbidity, which is in agreement with Anderson and Hampton (1980) and Vilks and Rashid (1977). Microcosm experiments indicate that, for Holyhead Harbour methanogenesis may be the major contributor to the methane pool held within the sediment. Furthermore sulphate-reducing bacteria, although natural competitors for the most probable substrates of methanogenesis, may be limited in their activity by sulphate concentrations at the depths where methane is being produced. |

| The intertidal fauna of a Belgian sandy beach was sampled on an hourly basis with a hand-pushed sledge to study circadiel patterns in species composition. Four assemblages could be distinguished with classification and ordination techniques. A first division separated the samples taken during daytime from the night samples. Both assemblages were subsequently divided into an ebbtide and a floodtide situation. Light intensity and tidal height were the most important variables explaining the variation in the Canonical Correspondence Analysis. |

| The genus Pseudoscopelus Lutken, 1892 is easily distinguished from the other Chiasmodontidae by the presence of well-defined rows of photophores. Until 2005, eight species were known. Pseudoscopelus scriptus was the first described by Lutken in 1892, then P. sagamianus by Tanaka in 1908, P. stellatus by Beebe in 1932 and P. altipinnis by Parr in 1933. Later in 1934, Fowler described three new species: P. microps, P. cephalus, and P. obtusifrons. These three species, known from only one specimen each, have not been recorded since. Lastly, an easily distinguishable species, P. scutatus, was discovered by Krefft in 1971. In a recent review, Prokoviev and Kukuev (2005, 2006) confirmed the validity of all species and described a new one P. aphos,... |
