1. Introduction

Parasites are common in the animal kingdom, and they play significant roles in marine aquaculture . Lernanthropus De Blainnville, 1822, is the most widespread genus of the family Lernanthropidae which is considered to be a common genus of parasitic copepods on fishes. They attach to the gill filaments of its host by means of the piercing action of the antennae . assisted by maxillipeds and third legs . The fourth pair of legs is modified, usually very long and apparently functionless. Most members are also characterized by the presence of plate-like structures and outgrowths of the fourth leg-bearing segment, often completely covering the posterior half of the body . Occasionally, the parasitic copepods may injure their host by feeding on mucus and skin and sucking the host’s blood especially those which attach to the gills. Such feeding activity can cause mechanical damage to the skin, fin erosion, and osmotic stress and may result in death in extreme cases . The combination actions of the antennae, maxilla, and maxilliped together with mandible of Lernanthropus latis which caused the damage were detected under light and scanning electron microscopies (SEM) [9]. The pathological effect such as erosion, haemorrhages, hyperplasia, and necrosis along the secondary lamellae of gill filaments of L. latis was observed with a great severity at the site of attachment. It is important to study the biology and life cycle due to the attachment location on the gill filaments and their blood-feeding habit which generates a threat to their host when outbreaks occur.
