I Recent "bioremediation of heavy metal pollution with different kinds of marine biomass including mar INE algae, bacteria and plants was reviewed. Operational factors and mechanisms of bioremediation process were further and analyzed. Moreover, the authors stated that further study should focus on the screening of marine bacteria with high accumulation CA Pacity of heavy metals, the effect of environmental factors on bioremediation process and the mechanism of bioaccumulation of heavy metals by marine organisms.

to face the integration of multiple-source heterogeneous mass data, Traditional integration methods and techniques cannot implement, until large data technology out of is now possible. Application of large data technology for multi-source heterogeneous marine Environment Monitoring data integration, Benefits marine Environment monitoring to share, Avoid islands of information, Simultaneous analysis of data, Mining provides the required data. The article focuses on the based on large data and data virtualization platform Technology, Reference ODM 2 Information model and MMI ORR Ontology semantic Framework for multiple source Heterogeneous marine environmental monitoring data integration issue , And on the basis of data integration, explores multi-source heterogeneous data queries, Consolidated Show implementation of the application . This research is helpful to solve the problem of massive marine environment monitoring data management problems , Meeting marine environment Research workers author large data requirements , Implementing data-driven decisions ,,Promote marine environment management level .

Infectious diseases of fish are generally classified into three categories: parasitic, bacterial and viral or fungal; Copepods are parasites that cause very serious damage to fish farms in fish farming. The objective of this study is the identification of copepods infesting Tilapia fish in extensive culture in the experimental fish station of the Higher Institute of Technology Education (ISET) in Mauritania. Crustaceans were collected from the gills of tilapia (Oreochromis niloticus Linnaeus, 1758). It is a species of fish introduced in Mauritania, raised in an extensive breeding system. Mauritanian specimens had the same morphology as the species identified in Congo-Kinshasa (1944) and Egypt (2000). The copepod Lamproglena monodi Capart, 1944, parasitizing freshwater fish in Mauritania, was originally described as a parasite of several Cichlids in Africa; it is presented as a new copepod species parasitic fish in this region.
