There are large numbers of phytoplankton (> 400 species) in many bodies of freshwater; phytoplanktons are commonest in habitats with high nutrient levels. The aquaculture research journal publishes the article on fish research, fish genetics, fish production, seedlings of fish, fish hatcheries, spawning, prawn research, shrimp research, aquatic flora, research on aquatic fauna etc. The source of articles within the journal will rate the journal by impact factor. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of comparable kind. It reflects the typical number of citations to recent articles published in science and science journals during a particular year or period, and is usually used as a proxy for the relative importance of a journal within its field. It’s first devised by Eugene Garfield, the founding father of the Institute for Scientific Information.
