Breeding & genetics

Salmon migrating from the open ocean to inland waters do more than swim upstream. To navigate the murkier freshwater streams and reach a spot to spawn, the fish have evolved a means to enhance their ability to see infrared light. Humans lack this evolutionary …

Researchers from the Queensland Brain Institute at The University of Queensland have uncovered a new form of secret light communication used by marine animals.

Scientists have solved a longstanding mystery about how some fish seem to disappear from predators in the open waters of the ocean, a discovery that could help materials scientists and military technologists create more effective methods of ocean camouflage.

The main objective of this study by Hooi Ling Khaw et al, Wageningen University, Netherlands, is to quantify the genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia.

On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph.

Scientists looking at the fecal material of 12 Baleen whales of three different species found some surprises. While Baleen whales are carnivores, feeding on fish and crustaceans, the microbes found in their guts the so-called whale microbiome share characteris…

When it comes to catching elusive prey, many fishes rely on a special trick: protruding jaws that quickly extend their reach to snap up that next meal. Now, researchers reporting in the Cell Press journal Current Biology on October 8 have found a clever way to…

Poxviruses are large DNA viruses of vertebrates and insects causing disease in many animal species, including reptiles, birds, and mammals. Although poxvirus-like particles were detected in diseased farmed koi carp, ayu and Atlantic salmon, their genetic relat…
