“…Collection of these and other annelids from the wild for bait has quite detrimental effects [69]. Annelids feed on bacteria and may be found at a high density at the sea bottom below cages used for culture of fish, and they are believed to be able to assist in the remediation of wastes from aquacultural facilities [70][71][72].…”

Parasites are very diverse and common in both natural populations and in stocks kept in aquacultural facilities. For most cultured species, there are important bacteria and viruses causing diseases, but eukaryotic parasites are also very important. We review the various combinations of aquacultured species and eukaryotic parasitic groups and discuss other problems associated with aquaculture such as eutrophication, zoonotic species, and invasive species, and we conclude that further development of aquaculture in a sustainable manner must include a holistic approach (One Health) where many factors (e.g., human health, food safety, animal health and welfare, environmental and biodiversity protection and marketability mechanisms, etc.) are considered.

“…In addition to the plant growth, we also observed that small-red segmented worms, with diameters between 1 and 3 mm and lengths between 5 and 8 cm, were able to live/survive in the anode part of the MS100 Plant-MFC ( Figure 5). These worms, based on their physical appearance possibly from Annelida phylum [73], are natural decomposers which maintain soil fertility by altering soil compositions through decomposing and transforming organic matter [74]. The latter provides support that the bioanode does support (some) biodiversity.…”

Wetlands cover a significant part of the world's land surface area. Wetlands are permanently or temporarily inundated with water and rich in nutrients. Therefore, wetlands equipped with Plant-Microbial Fuel Cells (Plant-MFC) can provide a new source of electricity by converting organic matter with the help of electrochemically active bacteria. In addition, sediments provide a source of electron donors to generate electricity from available (organic) matters. Eight lab-wetlands systems in the shape of flat-plate Plant-MFC were constructed. Here, four wetland compositions with activated carbon and/or marine sediment functioning as anodes were investigated for their suitability as a bioanode in a Plant-MFC system. Results show that Spartina anglica grew in all of the Plant-MFCs, although the growth was less fertile in the 100% activated carbon (AC100) Plant-MFC. Based on long-term performance (2 weeks) under 1000 ohm external load, the 33% activated carbon (AC33) Plant-MFC outperformed the other Plant-MFCs in terms of current density (16.1 mA/m 2 plant growth area) and power density (1.04 mW/m 2 plant growth area). Results also show a high diversity of microbial communities dominated by Proteobacteria with 42.5-69.7% relative abundance. Principal Coordinates Analysis shows clear different bacterial communities between 100% marine sediment (MS100) Plant-MFC and AC33 Plant-MFC. This result indicates that the bacterial communities were affected by the anode composition. In addition, small worms (Annelida phylum) were found to live around the plant roots within the anode of the wetland with MS100. These findings show that the mixture of activated carbon and marine sediment are suitable material for bioanodes and could be useful for the application of Plant-MFC in a real wetland. Moreover, the usage of activated carbon could provide an additional function like wetland remediation or restoration, and even coastal protection. 2 of 23 production; carbon fixation and storage; flood mitigation and water storage; water treatment and purification; and habitats for biodiversity. About 5-10% of the world's land surface is covered by wetlands [2]. A recent study reported that the global wetland area is between 15 and 16 million km 2 , in which about 8.9-9.5% is coastal wetlands [3]. Unfortunately, despite their critical role wetlands are facing a serious problem of losses caused by human activities. A study has shown that at least 33% of global wetlands had been lost as of 2009 due to human activities [1]. This loss was comparable to a previous study reporting that between 1970 and 2008, natural wetland declined globally by about 30% [4].Sediment pollution by human activities is a major problem for wetland ecosystems [5]. By nature, wetland sediments are able to remedy themselves from pollutants, such as petroleum hydrocarbon pollutants, due to the presence of diverse microbial communities [6]. However, in some cases such as to control hydrophobic organic compounds (HOCs), an in-situ amendment by human interference is applied for ...

“…Lorsque la série des stades morphologiques n'est pas connue, il est difficile de dire si un caractère observé est vraiment définitif et, dans le cas de son absence, savoir s'il l'est définitivement. De ce point de vue une quantité non négligeable d'information d'ordre systématique peut être obtenue en intégrant l'étude des cycles de vie aux travaux purement systématiques (Reish, 1977). Enfin, d'autres difficultés reposent sur une systématique des formes adultes qui est le plus souvent provisoire.…”

Les larves chétosphères des Polychètes Spionidae dans le Pacifique Remarques sur l'identification des stades larvaires par Michel Bhaud et Mireille Lefèvre Résumé. -Les auteurs complètent la description de trois types larvaires de Spionidae (Annélides polychètes) récoltés dans le Pacifique, archipel de la Société. Ces larves chétosphères sont caractéris¬ tiques de certains Spionidae au prostomium pointu à l'état adulte et peuvent très probablement être rattachées aux genres Dispio et Scolelepis. Une détermination fondée sur des caractères précis (prosto¬ mium, soies, branchies) bien que difficile, semble indispensable pour deux raisons : elle justifie l'étude des variations saisonnières et permet d'estimer l'emprise spatiale de la dissémination larvaire. Afin de faciliter cette identification il est nécessaire de connaître le moment d'apparition des caractères systé¬ matiques utilisés sur les spécimens adultes et pour cela les auteurs rappellent le grand intérêt de l'étude des cycles de vie.
