First record of the Ectoparasite Salmincola species (Crustacea) from Nigeria water body

Abstract

Plankton sampling and investigation of the Lagos harbour, some adjourning creeks and rivers was carried out using plankton, nets of 55µm and 100µm mesh sizes.  Yewa river which is located between Lat. 6°25’ – 6°30’N and Long. 2°50’ – 2°55’E was one of the sampling, stations with salinity values ranging from 0.17 – 0.43% for the 8 months of sampling period, indicating a constant freshwater condition.  In the course of analysis and identification of the copepoda, Salmincola species  which is an ectoparasite of fish was found, and this is its first record from Nigeria water body.
