RESUMEN: Se ha discutido que los reservorios se diferencian entre sí por la tasa a la cual manifiestan senescencia, sin embargo no ha habido esfuerzos para encontrar un indicador de senescencia que funcione mejor que la edad cronológica. Se construyó un indicador de edad funcional mediante una escala multimétrica que consiste en diez métricas descriptivas... Read More
ABSTRACT: It has been conjectured that reservoirs differ in the rate at which they manifest senescence, but no attempt has been made to find an indicator of senescence that performs better than chronological age. We assembled an indicator of functional age by creating a multimetric scale consisting of 10 metrics descriptive of reservoir environments that... Read More
RESUMEN: China comenzó a desarrollar pasadizos para peces en presas hidroeléctricas en la década de 1960, pero muchas fueron implementadas hasta la década del 2000, cuando una ley federal se aprobó en 2002 en la que se establece como requisito construir pasadizos para peces en aquellas hidroeléctricas que interrumpieran la migración de estos. En virtud... Read More
ABSTRACT: China began to develop fish passage at hydroelectric dams in the 1960s, but few were implemented until the 2000s, when a federal law was passed in 2002 that required fish passage at new hydroelectric dams that block fish migrations. Because of this regulation, in the past 10 years, about 40 fish passage facilities have... Read More
RESUMEN: El manejo de pesquerías basado en el ecosistema se ha percibido como algo deseable, pero de manera pragmática imposible de lograr debido a ciertos impedimentos que fueron identificados durante la fase de implementación del enfoque. Al pasar de los años, muchos de estos impedimentos se han resuelto pero esto no se le ha comunicado a los... Read More
ABSTRACT: Ecosystem-based fisheries management has been perceived as something desirable but pragmatically unachievable due to several impediments identified earlier during its implementation phase. Over the years, many of these impediments have been resolved but not well communicated to stakeholders, managers, scientists, and policymakers. As a result, several past impediments to implementing ecosystem-based fisheries management have... Read More
Un nuevo paradigma embrionario de impronta en programas de cultivo La fuga de salmones cultivados es un asunto considerable para la conservación y recuperación de muchas poblaciones naturales de salmón. Los manejadores de pesquerías han intentado minimizar las interacciones negativas de orden ecológico y genético entre los peces cultivados y los silvestres mediante el uso... Read More
A New Embryonic Imprinting Paradigm for Hatchery Programs Straying by hatchery-reared salmon is a major concern for conservation and recovery of many salmon populations. Fisheries managers have attempted to minimize negative ecological and genetic interactions between hatchery and wild fish by using parr-smolt acclimation facilities to ensure successful olfactory imprinting and homing fidelity. However, the effectiveness... Read More
Publications that involve the identification of important fisheries species generally do not relate scientific names to common names in landing records. For this reason, and in order to contribute to improving the quality of fisheries statistics and the works based on them, Mexico’s National Commission of Aquaculture and Fisheries (CONAPESCA) and the National Polytechnic Institute...

LONG-TERM RESEARCH As we conduct fieldwork and process samples in the lab afterwards, we often ponder what the real sample size is. We measured hundreds or thousands of fish, shrimp, clams, or whatever it is that we work on. These seem like adequate sample sizes until we remember that they were all collected at a... Read More
