Shrimp farming can be a highly lucrative business around the world, but has increasingly been characterized by intensification, with greater inputs of feed. Intensification has increased the risk of disease outbreaks and the proportion of operating costs represented by feeds can be as much as 60 percent. Various strategies have been investigated to address these issues, such as using functional feeds designed to improve the productivity and health of shrimp by additions of supplements. Moreover, researchers are continually evaluating appropriate replacements for more-expensive marine ingredients (Gatlin et al. 2007). One of the potential constraints in shrimp feeds, however, is the requirement for expensive cholesterol and pigments. Additional supplements such as probiotics, prebiotics, extracts and organic acids to create functional feeds further increases feed cost. Consequently, the purchase of commercial aqua feeds may be out of reach for many small-scale farmers around the world. The information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
