Freshwater aquaculture in the United States: Complying with environmental protection law and policy ArchiMer
Noble, M.
The author deal with the relations between the freshwater fish culture and the many regulations of the environmental protection in USA. The author develops the federal and state administrative frameworks (federal government administration of aquaculture, the state government administration of aquaculture), the freshwater aquaculture and water rights, the freshwater aquaculture and wetlands regulation, the freshwater aquaculture and water quality regulation, the freshwater aquaculture and wildlife laws, the private rights: common law nuisance.

Estimation de la qualité biologique de l'eau sur le littoral atlantique du Sud-Ouest de la France à l'aide des tests de croissance des larves de Mytilus edulis ArchiMer
His, Edouard; Quiniou, Francoise.
The quality of the seawater off the southwestern Atlantic coast of France was assessed by studying the effects of the water from three sites (Arcachon Bay, Mimizan and Capbreton) on larvae of the mussel (Mytilus edulis). Mussel larvae were raised in water samples taken at all three sites on March 12, 1991 and larval growth was monitored during 10 days. The results indicate that the water quality was best in the Bay of Arcachon, followed by Mimizan, whereas the water off Capbreton was possibly contaminated by pollutants.

Study of the water quality in Liaohe Park based on the model of GAM. OceanDocs
Song, Wenping; Dai, Yuanyuan; Dong, Yubo.
This paper assesses the quality of Daliao river through Liaohe Park based on the model of GAM for water quality analysis and the monitoring data from 2006 to 2011.The results showed that the value of pH per year tended to the average; the DO in 2011 was much higher than that in other years, and the DO in 2006 was lower than the standard value; the quality risk in six sections was still higher than the standard value in 2007, which was caused by the high concentrations of COD. However, the value of ammonia nitrogen changes was only 40% related to DO and COD.

Calidad ambiental de las aguas del tramo costero Bacuranao – Rincón de Guanabo, Playas del Este, Ciudad de La Habana, Cuba OceanDocs
Martín Páramo, A.; Pérez, M.; Beltrán, J.; Mancebo, H.; Rosabal, M..
This study presents some results of monitoring the beaches at East of Havana City, Cuba, during February and August corresponding to the rainy and less rainy seasons, respectively. For the bacteriological analysis were carried out 5 samplings in a period of 30 days, the rest of the samples was collected as punctual samples. The results are compared with those obtained in other samplings, specifically with 2004 period and with the requirements in the Cuban Standard NC: 22, (1999). Practically, the whole area showed pollution indicators deteriorated, such as: the permanganate oxidability value, bacteriological indicators and hydrocarbons, the last one corresponds to a lightly polluted area by hydrocarbons. The most affected areas were the outlet of the...

Evaluation de la qualité chimique des sédiments de la lagune de Fresco, Côte d'Ivoire OceanDocs
Kouassi, A.M.; Issola, Y.; Messoum, F.G..
Les sédiments de la lagune de Fresco proviennent essentiellement des apports continentaux (des vents, des eaux de ruissellement et des rivières Bolo et Niouniourou) et océaniques. On distingue les sédiments grossiers dans les stations à forts hydrodynamismes (station 4 et 5) et les sédiments fins dans la baie (station 1, 2 et 3). Les stations situées dans les zones à faibles hydrodynamismes sont caractérisées par des particules fines qui sont relativement plus riches en métaux lourds que les sédiments des stations proches de la passe. Il en résulte que les différents paramètres chimiques mesurées tant dans les eaux que dans les sédiments de la lagune de Fresco pourraient servir de référence pour caractériser une lagune côtière tropicale non polluée.

Pollution en lagune Ebrié et ses impacts sur l'environnement et les populations riveraines. OceanDocs
Adingra, A.A.; Kouassi, A.M..
La pollution induit et entraîne au quotidien la dégradation du milieu lagunaire Ebrié, avec des conséquences et des impacts multiformes sur la santé humaines et le développement socio économique. Les moyens financiers et matériels disponibles doivent être renforcés substantiellement pour mettre en place des infrastructures et des aménagements d'assainissement adéquats, tels que les centres d'enfouissements techniques de déchets d'une part, ainsi que les stations de traitement et d'épuration des eaux usées domestiques et industrielles d'autre part. De même, l'amélioration des compétences et des capacités en ressources humaines des différents acteurs institutionnels, reste déterminante pour le suivi et le contrôle de la qualité de l'eau ainsi que la gestion...

Índice numérico cualitativo para medir la calidad de las aguas costeras cubanas de uso recreativo OceanDocs
Miravet, M. E.; Ramírez, O.,; Montalvo, J.,; Delgado, Y; Perigó, E..
A escala internacional existen diversos índices numéricos que se usan para evaluar la calidad del agua a partir de las ponderaciones de variables físico químicas y biológicas seleccionadas de acuerdo al uso que se le dé al agua. Tienen la ventaja de ser fáciles de usar y proporcionan una idea rápida y resumida de la calidad. En Cuba, Suárez, Romero y Perigó (2003) propusieron un índice de contaminación para investigaciones ecológico-pesqueras el cual permite clasificar las áreas de interés pesquero de la plataforma cubana. Cuando se trata de evaluar la calidad del agua en zonas costeras accesibles al baño y la recreación, se aplica la norma nacional NC: 22 (1999), la cual considera las concentraciones de algunos microorganismos indicadores de la...
