This paper is a checklist of the fishes that have been documented, through both published and unpublished sources, in marine and estuarine waters, and out 200 miles, from the United States-Canadian border on the Beaufort Sea to Cabo San Lucas, Mexico. A minimum of 241 families and 1,644 species are known within this range, including both native and nonnative species. For each of these species, we include maximum size, geographic and depth ranges, whether it is native or nonnative, as well as a brief mention of any taxonomic issues.

“…La "Doncella" o la "Cabrilla de Perú" es el nombre común de Hemanthias peruanus (Steindachner, 1875), especie marina, pelágica-nerítica, con un rango de profundidad de 20-120m y de importancia en la pesquería artesanal (8). Esta especie pertenece a la familia Serranidae y se distribuye en el Pacífico oriental, desde Baja California, México hasta el norte de Chile, incluyendo las Islas Galápagos (9,10). Es una especie tropical que forma parte de la dieta de peces marinos cartilaginosos (11).…”
Objetivo. Evaluar la estructura comunitaria de helmintos y crustáceos parásitos en la doncella Hemanthias peruanus (Steindachner, 1875) procedente del norte de Perú. Materiales y métodos. Se adquirieron 75 especímenes (34 machos y 41 hembras) de H. peruanus procedentes del Puerto Cabo Blanco, Piura, Perú. Se registraron los datos de longitud total y el sexo de los peces. Para el análisis de la comunidad parasitaria, fueron calculados los índices ecológicos parasitológicos, índices de agregación, índices de diversidad alfa y asociación entre los parámetros biométricos de los peces y los índices parasitológicos. Resultados. El porcentaje de prevalencia total en las doncellas infectadas con al menos una especie metazoaria parásita fue del 65,33%, es decir 49 hospederos parasitados. El componente comunitario de la fauna de eumetazoos parasitaria en los peces evaluados estuvo dominada por la presencia de ectoparásitos (3 especies de monogeneos y 1 especie de isópodo) frente a la poca abundancia de especies endoparásitos (2 especies de trematodos, 1 especies céstoda y 1 especie de acantocéfalo). Probablemente la falta de asociación se deba a la influencia de otros factores bióticos o abióticos. Los parásitos más prevalentes presentaron una distribución del tipo agregada. El estimador de Chao-1 estima que la riqueza esperada fue de ocho. Los factores bióticos como la longitud y el sexo de los peces no se encontraron relacionados con los índices parasitológicos de ninguna especie parásita. Conclusiones. Registramos a H. peruanus como nuevo hospedero para para Ceratothoa gaudichaudii, Corynosoma australe, Parancylodiscoides signifer, Pronotogrammella scholzi y Scolex pleuronectis.
