| The eastern Mediterranean is susceptible to biological invasions because of its placement between the Atlantic, Pontic and Erythrean regions, busy maritime traffic, and lagoons and bays that are crowded with fish and shellfish farms. However, the greatest influx of invaders resulted from the opening of the Suez Canal in 1869, which allowed entry of Indo-Pacific and Erythrean biota. Exotic macro phytes, invertebrates and fish are found in most coastal habitats in the eastern Mediterranean. Some invaders have outcompeted or replaced native species locally, some are considered pests or cause nuisance, whereas other invaders are of commercial value. However, at variance with other invaded seas, the invasion into the eastern Mediterranean has increased the... |

| Sans Aneho, point de colonie togolaise! Cettre brève affirmation donne une idée de l'importance d'Aneho dans l'hisotoire du Togo. Mais si on prend c mot "Aneho" au sens littéral, elle est confuse. En effet, si l'on se base sur le point de vue des contemporains - Africains et Européens - qui se sont penchés sur cette localité, ell devrait s'appeler jusqu'en 1905 au lieu d'Aneho... oui, mais comment ? |

| Many algae species have been shown to have bactericidal or bacteriostatic substances (Glombitza, I979;Michaneck, 1979; Caccamese et al., 1980; Fenical & Paul, 1984; Niang& Hung, 1984). The antibacterialagents found in the algae include amino acids, terpenoids, phlorotannins, acrylic acid, phenoliccompounds, steroids, halogenated ketones and alkanes, cyclic polysulphides and fatty acids. In a large numberof marine algae antimicrobial activities are attributed to the presence of acrylic acid. |

| Aquaculture genetics research is carried out at the National Aquaculture Centre at Domasi, Malawi, by staff of the University of Malawi (UM) and the Department of Fisheries. The main species cultured are from genera Tilapia and Oreochromis. The genus Oreochromis was domesticated without proper identification of the various species especially in the subgenus Nyasalapia where three species (O. karongae, O. squamipinnis, and O. lidole) are difficult to identify before they reach breeding size. It is, however, observed that local fishers can identify these species using morphological characters. There have been no attempts to carry out deliberate domestication selection in the small-scale farms with the prevailing practices probably leading to deterioration of... |

| Biochar is the carbonaceous solid byproduct of the thermochemical conversion of a carbon-bearing organic material, commonly high in cellulose, hemicelluloses, or lignin content, for the purposes of carbon sequestration and storage. More specifically, the thermal conversion process known as pyrolysis occurs when carbon-containing substances are introduced to elevated temperatures in the absence of oxygen at varying residence times, yielding biochar. Several pyrolysis techniques employed to produce biochar differ in the temperature of reaction and residence time in the reactor. Different reactor residence times are described as slow (hours to days), fast (seconds to minutes), and flash (seconds). Fast or flash pyrolysis typically occurs around 500oC with... |

| Congo (Brazzaville) Significant aquatic biodiversity (freshwater and marine) Until 1985, the ORSTOM center at Point-Noire concentrated on biological and physical oceanography. Although the Center has reoriented towards agriculture, it maintains a program on the socio-economic monitoring of artisanal fishing. The aquaculture research station of Djoumouna, built in 1953, has lacked means of operating since 1991 and is being privatized. 69 |

| A bibliographical review of the taxonomy and biology of the two most important loliginid species, Loligo sanpaulensis and Loligo gahi, of the Argentine Sea is presented. The external morphology and the anatomy of the reproductor system for both sexes are described, as well as the larval period, nutrition, age and growth for both species. The geographical distribution and the relative abundance in relation to the size structure and maturity stage are analized. Abundance estimations of L.gahi, in the Southpatagonian shelf, were obtained from two research cruises data. Catch data for the two species is also presented. |

| An update of the knowledge on the three most important ommastrephid species that inhabit the SW Atlantic: Illex argentinus, Martialia hyadesi and Ommastrephes bartramii, is presented. Up to the moment, only I.argentinus was intensively studied. Its distribution, population structure, reproduction, growth and paralarval development are analyzed, togheter with other aspects of its biology, such as feeding, predators and parasites. Also its utilization for human consmption is considered. Regarding M.hyadesi and O.bartrami, information on their distribution and biology is presented. |

| Las capturas de langosta espinosa Panulirus argus (Latreille, 1804) en Cuba alcanzaron sus mayores volúmenes en la década de 1980 con un promedio anual de 11565 ton. En la década de 1990, la captura descendió a un promedio de 9327 ton, lo cual se ha visto agudizado entre 2000 y 2007 con un promedio de 6262 ton y una mayor variabilidad de las capturas, a pesar de un perfeccionamiento del sistema de manejo pesquero dado por: la disminución del esfuerzo pesquero y de la tasa de mortalidad por pesca desde 1999, el aumento del período de veda desde 2001 y el incremento gradual de la talla mínima legal de captura a partir de 2004. Los análisis más recientes sobre el estado de esta pesquería fueron presentados en el Quinto Taller Regional sobre la... |
