The vast majority of fish used was obtained from fish warehouses located in Cabo Frio coast of Rio de Janeiro (23? S and 42 ? W), 36 specimens of L. gastrophysus and 31 P. pagrus. We also obtained three specimens of P. pagrus and four T. lepturus at Mercado S?o Braz, located in Campo Grande, west of the city of Rio de Janeiro, commum fish fauna from the coast of Rio de Janeiro, (21- 23 ? S and 41-45 ? W). Six anisakid species of nematode larvae were found in the mesentery, the general cavity, liver and muscles. Those species are: Anisakis simplex, Terranova sp. Contracaecum sp. Hysterothylacium sp.1, sp.2 and Raphidascaris sp.. Anisakis simplex larvae were found in L. gastrophysus with prevalence (P) of 22.2% and mean abundance (MA) 0.53 for T. lepturus P = 50%; Terranova sp. From L. gastrophysus P = 8.3% and AM = 0.08, T. lepturus P = 25% and P. pagrus P = 5.8%; Contracaecum sp. From L.gastrophysus P = 8.3% and AM = 0.08; Hysterothylacium sp.1 from T. lepturus P = 75% and P. pagrus from P = 100%; Hysterothylacium sp.2 from L. gastrophysus P = 25% and AM = 0.47 and T. lepturus with P = 25%; Raphidascaris sp. From L. gastrophysus from P = 11.1% and AM = 0.42 and P. pagrus from P = 55.8%. These nematodes are described and illustrated herein. A revision of available literature, concerning nematodes belonging to these genera, was made. This is the first record of occurrence of Anisakis simplex, Terranova sp. e Contracaeum sp. parasitizing L. gastrophysus the coast of the state of Rio de Janeiro. It was concluded that infection in fish of high consumption and commercial importance, make the consumption of these fish, especially without prior adequate thermal processing, a potential risk from the point of view public health. / Com o objetivo de pesquisar e identificar as larvas de anisak?deos presentes nas v?sceras, cavidade geral, mesent?rio e musculatura de peixes marinhos de import?ncia comercial provenientes do litoral do estado do Rio de Janeiro, Brasil, foram examinados 36 esp?cimes de Lophius gastrophysus, 34 esp?cimes de Pagrus pagrus e 4 esp?cimes de Trichiurus lepturus. A grande maioria dos peixes utilizados foi obtida de entrepostos de pescados localizados em Cabo Frio, litoral do estado do Rio de Janeiro (23? S e 42? W), sendo 36 exemplares da esp?cie L. gastrophysus e 31 de P. pagrus. Foram obtidos ainda 3 exemplares de P. pagrus e 4 de T. lepturus no Mercado S?o Braz, localizado em Campo Grande, zona oeste da cidade do Rio de Janeiro, peixes estes oriundos da costa mar?tima do estado do Rio de Janeiro, (21-23? S e 41-45? W). Seis esp?cies de larvas de nemat?ides anisak?deos foram encontradas, Anisakis simplex, Terranova sp., Contracaecum sp., Hysterothylacium sp.1, Hysterothylacium sp.2 e Raphidascaris sp., provenientes do mesent?rio, cavidade geral, f?gado e musculatura. Larvas de Anisakis simplex foram encontradas em L. gastrophysus com preval?ncia (P) de 22,2% e abund?ncia m?dia (AM) 0,53 e em T. lepturus com P=50%; Terranova sp. em L. gastrophysus com P=8,3% e AM=0,08, em T. lepturus com P=25% e P. pagrus com P=5,8%; Contracaecum sp. em L. gastrophysus com P=8,3% e AM=0,08; Hysterothylacium sp.1 em T. lepturus com P=75% e em P. pagrus com P=100%; Hysterothylacium sp.2 em L. gastrophysus com P=25% e AM=0,47 e em T. lepturus com P=25%; Raphidascaris sp. em L. gastrophysus com P=11,1% e AM=0,42 e em P. pagrus com P=55,8%. Estes nemat?ides foram descritos e ilustrados, junto ? revis?o da literatura existente a respeito dos nemat?ides pertencentes aos presentes g?neros. Este ? o primeiro registro da ocorr?ncia de Anisakis simplex, Terranova sp. e Contracaeum sp., parasitando L. gastrophysus do litoral do estado do Rio de Janeiro. Concluiu-se que a presen?a de larvas de anisak?deos dos presentes g?neros com preval?ncias de infec??o consider?veis em peixes de elevado consumo e import?ncia comercial, torna o consumo destes peixes, principalmente sem pr?vio e adequado processamento t?rmico, um risco em potencial sob o ponto de vista de sa?de p?blica.
