Condición física de las poblaciones de lisa Mugil spp. del Pacífico mexicano: Bases para un manejo sostenible de sus pesquerías
AI summary Read the abstract
Researchers characterize two euryhaline mullet species (Mugil cephalus and M. curema) from the Mexican Pacific, examining their morphophysiology, blood biochemistry, microplastic ingestion levels, and parasitic disease burden to inform sustainable fisheries management and aquaculture development.
La presente obra tiene como objetivo aportar información de dos especies de la familia Mugilidae conocidas localmente como “lisas”: ‘Mugil cephalus’ y ‘M. curema’, las cuales se caracterizan por soportar amplios rangos de salinidad (eurihalinos), lo que les permite habitar en ambientes de agua dulce y estuarinos, donde desempeñan un papel ecológico importante en el reciclado de nutrientes, y adaptarse fácilmente a diferentes niveles de salinidad. Esta gran capacidad fisiológica es clave para su supervivencia y amplia distribución geográfica. En esta obra se describen aspectos de su biología, como su condición morfofisiológica, bioquímica sanguínea y grado de ingestión de microplásticos, así como del efecto de las enfermedades parasitarias sobre la condición física de sus poblaciones. Los resultados obtenidos se presentan para contribuir al establecimiento de bases para su ordenamiento pesquero y el desarrollo de la biotecnología de su cultivo. En este sentido, se ha sugerido que las lisas tienen un gran potencial en la acuicultura, debido a su amplia aceptación en los mercados locales e internacionales por la calidad de su carne y su gran adaptabilidad para crecer en condiciones controladas, todo esto para apoyar a disminuir su presión pesquera dada su alta demanda.

Presença e efeitos da poluição plástica em peixes marinhos e de água doce
AI summary Read the abstract
This thesis (in Portuguese) investigates plastic contamination in freshwater and marine fish, examining physiological, functional, and ecological effects across multiple levels of biological organization, including food safety implications for human consumption. The author finds that the scientific community has made progress on understanding individual-level effects but that broader ecological impacts and ecosystem-level consequences remain underexplored. The work contributes important evidence that plastic pollution in fish poses intertwined risks for wildlife and the people who eat them.
Estado actual del conocimiento sobre el efecto de los microplásticos en comunidades de macroinvertebrados de ecosistemas lóticos
AI summary Read the abstract
Researchers reviewed the effects of microplastics on freshwater macroinvertebrate communities, finding that filter-feeders, shredders, collectors, and herbivores all ingest microplastics, leading to digestive blockages, increased mortality, reduced fecundity, inflammation, and altered behavior, with significant ecosystem-level consequences.
