Combining instruments can collect vital data on the vertical structure of the ocean.

Despite a number of challenges that still need to be overcome, genome sequencing has a growing range of practical applications in aquaculture and, as costs come down, it is going to be increasingly widely used.

A new study from Martin Benavides, published in the Journal of Unmanned Vehicle Systems, offers some hope for murky-water shark researchers; mid-day sunshine and little wind doesn’t only make for pleasant weather—it may also be better for drone-based shark photography.

Rusty crayfish may not have a nose as such, but they do have an exceptional sense of smell. With a “sniff”, these crustaceans can glean all sorts of information about the world around them. If rusty crayfish can “smell” a predator, such as largemouth bass, it stands to reason the crayfish will seek to reduce their chances of becoming dinner…

As fisheries are starting to harvest krill resources to feed the world’s population, this must be done in a sustainable manner, based on accurate, scientific observations. Scientists at NOAA in the USA are now using sophisticated new acoustic technology to truly “see” krill in the Southern Ocean. How will this scientific research help conserve the Southern Ocean ecosystem?

For a salamander, being able to drop a “zombie-tail” clearly has survival benefits, but so too does having a tail in the first place.

They may not be pretty but wolffish they have some amazing abilities - like living in places where water temperatures drop to below freezing!

Whilst the era of self-driving cars might still be a way off, automated aquaculture may arrive much sooner than you think.
