Two marine parasitic crustaceans new to the Belgian fauna

Since many commercial fish species and populations are parasitized (e.g., [2]), with often a severe impact on fitness and health, knowledge on parasites is of considerable ecological and economic importance [3]. In addition, organisms from lower trophic levels that form the base of the food chain, can be subject to parasites (e.g., [4]). In Belgium efforts have been taken to assess patterns and prevalence of parasites on whiting and dab during the years 1996–2011 [5], and to quantify parasites originating from marine dredge spoil disposal sites [6]. Otherwise, parasites have only been reported occasionally or as a sideproduct of a survey (e.g., [7]).
