Abstract

The aquaculture activity of Trachinotus blochii has a high economic value. One of the problems that is commonly found in fish cultivation is ectoparasite crustaceans. It is considered ectoparasites because crustacean may cause bacteria and virus secondary infections. The purpose of this study is to identify the genus of ectoparasite crustaceans that infest T. blochii which are cultivated in hatcheries and floating net cages. Observation of T. blochii samples from cultivation in hatcheries and floating net cages on the body surface and gill examination using the qualitative method. Scrapping samples that have signs of being infected with ectoparasite crustaceans. Identification of ectoparasite crustaceans by a microscope at 100x and 400x magnifications. There are ectoparasite crustaceans found infecting T. blochii, the crustacean that belongs to genus Canuella. Canuella prevalence value is 3.3% in hatcheries tubs and 3.65% in floating net cages. There is one genus of ectoparasite crustaceans found, namely the genus Canuella which infects T. blochii that is cultivated in hatcheries tub and floating net cages.
