Abstract Aquaculture practice in Mexico is commonly carried out with some freshwater species, which are introduced the region for its production, technology developed other countries. The growth of this activity has been slow, sometimes leading to loss investments due difficulties implementation foreign technological packages, poor selection and inadequate management or farming sites, even confusing legal procedures. stands development crops exotic species more than native most type.

Microplastic contamination has become a topic of interest and concern worldwide due to its persistence the possible effects it may cause environment. When microplastics are present, they can alter their physical properties, negatively affecting surrounding fauna, such as sea turtles that use beaches nest in sand. In this study, exposure turtle nests on Nautla Vega de Alatorre, Veracruz, one main nesting areas for green Chelonia mydas, well Kemp’s ridley Lepidochelis kempii from Gulf Mexico,...

Dormirator maculatus (n=184) was collected in the Alvarado Lagoon, Mexico during a year period (Oct. 1993-1994). In helminthologic review, presence of Clinostomum complanatum (82.3%), Neoechinorhynchus golvani (76.1%), Spiroxys sp. (21.3 %), and Camallanus (6.2%) registered. Reduction hematocrit caused by such infection is significant (t, a= 0.05).

A helminthological survey was conducted on 78 red lionfish, Pterois volitans, collected in the Veracruz Reef System National Park (VRSNP). Register: trematodes (5 spp.), cestodes (1), and nematodes (2). Prevalence per species < 30% mean intensity 6.0. Three new host records are reported herein. The lionfish is infected by of endoparasites generalist played a role as accidental host.

The objective of this study was to describe the morphology Clibanarius antillensis Stimpson, 1859 megalopae collected in vicinity Isla Sacrificios, Mexico, and compare it previous descriptions originated from Brazilian Panamanian specimens raised laboratory conditions.

Se espera una disminución hasta el 40% de la pesca por efecto del cambio climático en regiones tropicales, causando repercusión productividad primaria afectando mayormente a poblaciones peces que llevan cabo su reproducción arrecifes y estuarios; sumado esto no se cuenta con acceso físico económico alimentos suficientes, seguros nutritivos para satisfacer las necesidades alimentarias población. Por estas razones pensó acuacultura como respuesta producción alimento sustentable, un pez nativo...
