“…De nombreuses publications indiquent que cette méthode d'épuisement des stocks sous-estime le plus souvent de 20 % environ la taille réelle des populations (voir par exemple BOHLIN et UNDSTROM, 1977 ;MAHON, 1980). Mais ces auteurs ont utilisé la formule de ZIPPIN (1956) pour étayer leurs propos alors que la formule de CARLE et STRUB (1978), que nous avons utilisée, produit des biais négatifs moins importants et est plus robuste parce qu'elle supporte des conditions d'application moins sévères (cowx, 1983 ;GERDEAUX, 1987). Certes, la question n'est pas tranchée, et les valeurs présentées ici restent encore à préciser, mais elles fournissent néanmoins un ordre de grandeur de la taille des populations étudiées.…”

“…Les effectifs et les probabilités de capture ont été estimés par espèce et par station avec la méthode de CARLE et STRUB (1978) grâce au programme informatique proposé par GERDEAUX (1987). En raison de faibles efficacités de captures, les poissons juvéniles de moins de 30 mm ont été exclus de cette étude, et seules les captures totales ont été indiquées pour les épinoches et les épinochettes.…”

Le peuplement ichtyologique d'un marais littoral endigué, géré en eau douce, a été étudié sur une zone de 2 700 ha, située au nord du marais Breton-Vendéen (Loire-Atlantique, France). Le réseau hydraulique, qui représente près de 16 % de cette surface, se compose, d'environ 91 m de linéaire de fossés par ha (en tout 234 km) et de bassins présents uniquement dans la partie d'origine salicole du marais. Les hauteurs d'eau, l'envasement et le recouvrement par la végétation aquatique dépendent de la gestion humaine et sont très variables (moyennes respectives : 42 cm; 43 cm; 70 %). Cela se traduit par un morcellement spatial de l'habitat pour les poissons. La stratégie d'échantillonnage adoptée, qui tient compte de cette hétérogénéité, a permis de décrire un peuplement comportant 21 espèces. Dominé par les poissons-chats et par les anguilles, ce dernier est caractéristique de la zone à brèmes des cours d'eau. Les abondances sont relativement élevées (en moyenne 315 kg/ha et 11 460 poissons/ha), mais elles sont très hétérogènes. L'évolution qualitative et quantitative de la répartition spatio-temporelle est décrite à l'aide d'une analyse factorielle des correspondances portant sur 74 échantillons prélevés par pêche électrique entre 1987 et 1989. Bien que l'approche de ce milieu soit complexe et les références bibliographiques relativement rares, l'analyse des premières données permet d'ores et déjà d'identifier quelques problèmes de gestion ayant des répercussions directes sur le peuplement piscicole de cette zone.The dammed up marshes of the French Atlantic coast cover about 200 000 ha between River Vilaine and the « Bassin d'Arcachon ». Eighty eight % are managed with freshwater. They constitute original environments initially created for agriculture or for salt production, and they are now threatened by land abandonment within the next decade. Concurrently to aquaculture (in created or existing ponds), exploitation of the fish stocks in the ditchweb is likely to encourage a diversification of agricultural activities. Unfortunately, bibliographic analysis reveals the relative scarceness of research about sampling methods and qualitative or quantitative characteristics of these fish communities. This is quite surprising considering the importance of the ditchwed of this kind of environment outlined by several authors. In the Netherlands, BELTMANN (1984) assessed that there is a total of 400 000 km of ditches. In France, the littoral dyked marshes of the Atlantic coast couid comprise 20 000 km of ditches and about 24 000 ha of open water. The present work provides for the first data on the fish community of Bourgneuf marsh.The northern part of the marsh of Bourgneuf, 2 700 ha provided whith f reshwater, contains nearly every kind of landscapes found throughout the whole Breton-Vendéen marsh. The pattern of the ditch network strongly changes from a zone to another (fig.1) : presence of former salt pans in the western part, regular geometric shapes in the recently created polders next to the River Falleron, irregular di...

Thii report has been reproduced directly from the best available copy.AvallaMe to DOE and DOE contractors from the Office of Scientific and Techni. yearly ratio of energy derived from gas compared to that from coal is approximately 5 to 1; a higher percentage of coal was used in winter months. A dry vacuum system was installed in May 1990 to collect dry fly ash. Fly ash is now transported to a landfill, and all sluice water discharge to Rogers Quarry has been terminated. By January 1994, a bottom ash dewatering system was installed and functional at the steam plant. The wet bottom ash is sent through the system and the ash residue is trucked to a landfill. The wash down water generated by this process is recycled in the system for future wash down use. The last actual discharge of wet bottom ash to Rogers Quarry occurred in July 1993. CONTENTS (continued)APPENDIX Biological Monitoring Program LIST OF FIGURES Biological Monitoring ProgramPrevious biological monitoring of McCoy Branch was conducted from 1989 through 1990 and included evaluations of instream toxicity, bioaccumulation (in Rogers Quarry), fish community, and benthic community parameters @yon et al. 1992). This biomonitoring indicated that McCoy Branch was receiving low to moderate stress. The instream toxicity studies produced only limited effects on fathead minnow and Ceriodaphnia survival and fecundity in 7-d laboratory tests. In situ snail studies indicated that more stress was seen below Rogers Quarry than above it. Bioaccumulation studies indicated that selenium, arsenic, and possibly thallium were elevated in largemouth bass from the quarry in comparison to levels in reference fish. These fish also had severe deformities present in bony structures.Similar deformities in fish from the stream proper were noticed by the fish community studies in McCoy Branch below the quarry. A fish community was absent in McCoy Branch above the quarry, while the stream immediately below the quarry had an atypical community for a small stream with many species tolerant of degraded conditions. The benthic macroinvertebrate community assessment indicated the maximum impacts were above the quarry, with all sites showing more impact than companion reference sites. Some temporal recovery was noted in the benthic community above the quarry, which was not seen at downstream sites. Overall, McCoy Branch demonstrated moderate impacts on the biological communities, with perhaps some improvement since the cessation .of fly ash disposal. If the system is beginning to recover, then the additional biomonitoring covered in this report should detect further improvement in the above areas. WAWR QUALITYThe water quality data show that although some metal concentrations, levels of radioactivity, and organic constituents are still above reference values, the average values of these contaminants in surface water and groundwater samples in McCoy Branch watershed generally have been decreasing yearly since 1988. During this period, nitrate-nitrogen values have actually fallen b...
