A new study shows that if current aquaculture and agriculture practices remain unchanged into the future, wild forage fish populations likely will be overextended by the year 2050, and possibly sooner. However, making sensible changes in aquaculture and agriculture production would avoid reaching that threshold.
NEW YORK (June 13, 2018)— An age-old challenge of determining the right amount of fish to harvest from the sea has finally been overcome with the creation of a new biomass-yield model that captures all the necessary factors for accuracy, according to a new WCS (Wildlife Conservation Society) study.

Research for the five-year project will support autonomous unmanned marine vehicle platforms for coastal surveillance, coastal surveys, target tracking and protection of at-sea assets. The project will entail developing unmanned surface vehicles that serve as “motherships” for unmanned underwater vehicles and aerial drones, thereby enabling multi-vehicle, multi-domain capability that may serve as a mobile coastal monitoring system.
When it comes to finding protection and a safe feeding ground, fish rely on towering blades of seaweed, like kelp, to create a three-dimensional hiding space. Kelp forests have been shown to be one of the most productive systems in the ocean with high biodiversity and ecological function. However, in recent decades, many kelp habitats have been taken over and replaced by lower turf-dominated seaweed species. Researchers at the University of New Hampshire have found that this change in the seascape may impact the behavior of fish and could be leaving them less options for refuge and more vulnerable to predators.
Comparing how the chromosomes of modern-day birds and turtles are structured can help scientists figure out how dinosaur genomes might have looked. An Iowa State University scientist contributed to an international research team that recently published its findings reaching back through 260 million years of genomics.
Rutgers University–New Brunswick engineers have created a 3D-printed smart gel that walks underwater and grabs objects and moves them. The watery creation could lead to soft robots that mimic sea animals like the octopus, which can walk underwater and bump into things without damaging them. It may also lead to artificial heart, stomach and other muscles, along with devices for diagnosing diseases, detecting and delivering drugs and performing underwater inspections.
Funny thing about restaurant menus. They often are among the best gauges of telling us how tastes have changed – quite literally – and how economic good times come and go.
The findings, published today in Cell by scientists at Van Andel Research Institute (VARI), University of Georgia (UGA) and Washington State University, detail the structure of MBH, a molecular complex involved in microbial respiration. The near-atomic resolution images are the first ever of MBH and show that its structure is remarkably similar to its counterpart in humans, Complex I.
