EVALUATION OF PARASTIC INFECTION OF PRAWNS IN CALABAR RIVER, CALABAR, CROSS RIVER STATE
Abstract
ABSTRACT
The study was aimed at evaluation of Parasitic infection of Prawns in Calabar River,
Calabar Cross River State Nigeria. Calabar River was chosen was the site for the study. All
the prawn species caught in these water bodies were weight. measured and screened for
parasites. A total of Four hundred and ninety-seven Prawn where collected. dissected and
examined for parasites externally and internally. In all. 223 (44.87%). Prawns with the
highest weight infected were 40-49 (56.25%) and the least infected was weight 120-
129(2.00%). Ectoparasites were mostly isolated from prawn weight 90-99(14.25%) and
least at weight 50-59(5.00%). While endoparasites were mostly recovered from weight of
90-99(14.28%) and least at weight 60-69(8.57%). Parasites recovered were from the class
of Protozoa (Apisioma). Ciliate (Trichodina). Trematodes (Paragonimus sppy and
Nematodes (Ascaris spp. Capillaria and Procamallanus. The present study demonstrated
that the giant fresh water prawn mucrobrachuim rosenbergii serve as host for a wide range
of epibionts and parasites. Coordinated efforts are necessary to further reduce the risk of
sea food-associated illness. Continued surveillance will be important to assess the
effectiveness of current and future prevention strategies.
