Mediterranean teleosts and salmonid species, have been discussed in detail by Merrifield et al .
(2010a) and Dimitroglou et al . (2011) and thus will not be repeated in this chapter.
However, the bacterial probiotic strains Ppd11 and Pdp13, from the Alteromonadaceae
family, are among the most well researched Gram-negative bacterial probiotics in fish and
therefore some attention will be paid to these strains (Díaz-Rosales et al . 2006; 2009; Seaenz
de Rodrigáñez et al . 2009; de La Banda et al . 2010; Tapia-Paniagua et al . 2012). These strains
