Gestionando las expectativas de la acuaponia en el salón de clases: mejorar la apreciación de los recursos acuáticos en el aprendizaje y docencia académica

RESUMEN: Exponer a la siguiente generación a la naturaleza puede generar un fuerte apego a los recursos acuáticos, sin embargo no siempre podrá ser posible permitir a los estudiantes estar en contacto con ambientes acuáticos naturales. La acuaponia, que es una combinación de la acuacultura y la hidroponía, puede ser una poderosa herramienta en escuelas... Read More

Desempeño ambiental de la acuacultura marina con jaulas de red en los Estados Unidos de Norteamérica

RESUMEN: Los Estados Unidos de Norteamérica (EE. UU.) poseen una pequeña industria de acuacultura de salmones mediante jaulas de red que data desde hace cuatro décadas y una incipiente industria de cultivo con jaulas de otras especies de peces marinos. El sector de la acuacultura con jaulas de red en los EE.UU. ha mejorado la eficiencia de sus recursos en términos... Read More

Poniendo al lomo rojo de vuelta en el Lago Redfish, veinte años de progreso en el salvamento de la población de salmón más amenazada del noroeste

RESUMEN: En noviembre de 1991, el Servicio Nacional de Pesquerías Marinas de los Estados Unidos de Norteamérica, ingresó al salmón (Oncorhynchus nerka) en el Acta de Especies Amenazadas de los Estados Unidos (AEA) bajo la categoría de amenazado. Los últimos remanentes conocidos del stock del Río Snake, regresaron al Lago Redfish, Valle Sawtooth, en la... Read More

Putting the Red Back in Redfish Lake, Twenty Years of Progress Towards Saving the Pacific Northwest’s Most Endangered Salmon Population

ABSTRACT: In November 1991, the U.S. National Marine Fisheries Service listed Snake River Sockeye Salmon (Oncorhynchus nerka) as endangered under the U.S. Endangered Species Act (ESA). The last known remnants of the Snake River stock return to Redfish Lake in the Sawtooth Valley in central Idaho. In the ensuing two decades since the ESA listing,... Read More

Solutions to California’s Drought Issues: Modeling Suggests Ways to Conserve Chinook Salmon in the Face of Water Diversion

Chinook Salmon Oncorhynchus tshawytscha smolts emigrating the Sacramento River in California must navigate through a delta complex with water diversions that confer lower survival for entrained fish that leave the river. Russell Perry of the U.S. Geological Survey, Western Fisheries Research Center, and his colleagues fit an entrainment model to telemetry data and found that... Read More

Probiotics Show Promise for Aquaculture

Television viewers are now being carpet-bombed with advertising for probiotics that are alleged to improve human health via promotion of beneficial gut bacteria. But probiotics may play a real role in aquaculture where ZhiPing Yang (Dalian Huixin Titanium Equipment Development Company) and colleagues fed live yeast to cultured sea cucumbers and later challenged them to...

Using a Video Lander to Assess Difficult Marine Habitats

Deep temperate marine zones are known to support significant biological production, but they are difficult to sample because they are too deep for SCUBA and too complex for traditional nets. Ryan Easton of Oregon State University and his other colleagues found a way to do it that is not only feasible but quantitative. This journal... Read More

Bluegill Can Be Managed More Effectively with Bag Limits!

Many inland fisheries historically have allowed unlimited harvest of panfish, or have extremely liberal bag limits. The management paradigm is that fishing mortality is usually low and high harvests benefit angling by improving growth and preventing stunting. However, a new study by Andew Rypel of the Wisconsin Department of Natural Resources, Bureau of Science Services,... Read More
