“…A recusa da alimentação, descoloração, letargia e lesões nos olhos são descritos por Mueller et al (1994) As taxas de sobrevivência dos peixes obtidas para o TC e para os tratamentos T1 e T3 não diferiram entre si, porém, foi obtida diferença significativa (p<0,05) em relação à sobrevivência do T2. Em relação à sobrevivência do parasito, os tratamentos T1 e T2 não diferiram entre si (p>0,05), porém diferiram do TC e do T3 (p<0,05) apontando que os tratamentos T1 (banho em água doce) e T2 (banho empregando-se formalina na concentração de 1:2.000) foram eficientes em eliminar N. melleni da garoupa-verdadeira.…”

RESUMOO diagnóstico precoce de patologias no meio aquático constitui-se em uma necessidade vital para o sucesso dos cultivos. Considerados como parasitos oportunistas, surtos de infestação de monogenóides capsalídeos podem ocasionar mortalidades massivas gerando enormes prejuízos nos cultivos. Exemplares de garoupa-verdadeira Epinephelus marginatus (Lowe, 1834), com peso médio de 142,74 ± 38,65 g, apresentaram recusa da alimentação e sintomas como o escurecimento do corpo, natação errática, opacidade dos olhos, exoftalmia e hemorragias em diversas áreas do corpo. Alguns peixes apresentavam lesões no globo ocular e cegueira. Após análises dos peixes foi identificada a ocorrência do parasito Neobenedenia melleni. Este trabalho teve por objetivo testar o efeito de diferentes tratamentos por imersão em diferentes concentrações de formalina e água doce na erradicação de monogenoides capsalideos na garoupa-verdadeira. Foram testados três tratamentos em forma de banhos: T1 (água doce por 10 minutos); T2 (formalina: 1:2.000 por 10 minutos) e T3: (formalina: 1:4.000 por 10 minutos). Os tratamentos foram avaliados através de raspado de tecido epitelial, montados entre lâminas e lamínulas e observado ao microscópio de luz. Observou-se que nas condições testadas o T1 e o T2 foram eficientes na eliminação dos monogenóides capsalídeos na garoupa-verdadeira. The precocious diagnosis of pathologies in the aquatic way is constituted in a vital need for the success of the cultivations. Considered as parasites opportunists, infestations of monogeneans capsalides can cause missal mortalities resulting in enormous damages in the cultivations. Juveniles of dusky grouper Epinephelus marginatus (Lowe, 1834), with medium weight of 142.74 ± 38.65 g, presented refusal of the feeding and symptoms as the darkening of the body, erratic swimming, opacity of the eyes and hemorrhages in several areas of the body. Some fishes presented lesions in the eyeball and blindness. After analyses of the fish the occurrence of the parasite Neobenedenia melleni was identified. This work objective was to test therapeutic treatments seeking the monogenean capsalid eradication in juveniles of dusky grouper. Three treatments were tested in form of baths: T1 (fresh water for 10 minutes); T2 (formalin: 1:2,000 for 10 minutes) and T3: (formalin: 1:4,000 for 10 minutes). The treatments were evalueted by scraping epithelium tissue, mounted in slide glass and cover slip and observed by light microscope. It was observed that in the tested conditions T1 and T2 were efficient in the elimination of the monogeneans capsalids without presenting lethality in the dusky grouper. PALAVRAS-CHAVE

The original description of N. melleni was based on specimens collected from fish kept at the New York Aquarium (MacCallum 1927), where outbreaks of the parasite continued for decades (Jahn & Kuhn 1932, Nigrelli & Breder 1934, Nigrelli 1947, Thoney & Hargis 1991.…”

Two different genetic types of tilapia, Mozambique tilapia Oreochromis mossambicus (MT), and Pargo-UNAM (PU; a synthetic hybrid whose genetic composition is 50% Florida red tilapia, 25% Rocky Mountain tilapia, and 25% red variant Oreochromis niloticus), were acclimatized to salinity and exposed to seawater from the Gulf of Mexico off the port of Veracruz, Mexico. Both fish types were infected by the monogenean ectoparasite Neobenedenia sp. and were killed within 2 to 3 wk. A crude worm extract was prepared from whole specimens collected during the original outbreak and used to immunize naïve hosts of the same 2 types of tilapia. Immunized fish were then exposed to seawater, which resulted in Neobenedenia sp. infection. Immunization did not confer any protection against Neobenedenia sp. infection. However, the experiment enabled detailed analysis of the dynamics of infection and comparison of the effects of the parasite on the 2 host types. Although both tilapia types exhibited similar resistance to infection (as they harbored similar parasite burdens in the early phase of infection), PU is less tolerant to Neobenedenia sp., as a mean parasite abundance of ca. 50 worms fish -1 killed all hosts within a fortnight, while 22% of MT survived up to 3 wk, harboring a mean parasite abundance of ca. 900 worms fish -1. Our results suggest that, as reported elsewhere, Neobenedenia sp. could negatively affect mariculture off the Mexican coast of the Gulf of Mexico.
