Resumo
O cobia é o único representante da família Rachycentridae e, devido às suas qualidades zootécnicas, a produção desse peixe tem sido implementada em vários países, tais como os Estados Unidos, México e Brasil. Tuxophorus caligodes é um parasito de peixes marinhos amplamente distribuído no mundo. Para o presente relato, 15 juvenis de cobias foram coletados de tanques-rede, em uma fazenda marinha em Ilhabela, Estado de São Paulo, Brasil, no inverno de 2011. Os peixes foram sujeitos à eutanásia por meio de concussão cerebral, pesados (280 ± 70,5 g) e medidos (27 ± 1,97 cm). Após exame externo sob um estereomicroscópio, os ectoparasitos presentes na superfície do corpo foram coletados, fixados e processados para identificação. Dos 15 peixes examinados, dois apresentavam-se parasitados indicando a prevalência de 13,3%. Esse é o primeiro relato de Tuxophorus caligodes em cobias no Brasil.

Tuxophorus caligodes is a widespread parasite of marine fish worldwide. For the present report, 15 juvenile cobias were collected from net cages on a fish farm in Ilhabela, state of São Paulo, Brazil, in the winter of 2011. The fish were sacrificed by means of cerebral concussion, and then weighed (280 ± 70.5 g) and measured (27 ± 1.97 cm). After external examination under a stereomicroscope, ectoparasites present on the body surface were collected, fixed and processed for identification. Out of the 15 fish examined, two were parasitized with Tuxophorus caligodes, thus indicating a prevalence of 13.3%. This is the first report of Tuxophorus caligodes in cobias in Brazil.
