Seven years later: BP oil spill settlement funding new way to manage fish populations

Thu, 20 Apr 2017 09:03:03 EDT ~ Understanding the severity of the BP oil spill has led researchers to a barcoding fish eggs. This will help them to determine where fish are spawning, hopefully leading toward the creation of protected areas and a baseline should another oil spill occur. Find out more...

'Eating with the eyes' is hard-wired in the brain

Thu, 20 Apr 2017 09:02:11 EDT ~ Scientists have discovered prey detector neurons in the visual system that project to the feeding center in the hypothalamus, and they observed neurons in this circuit firing upon seeing prey. The study demonstrates the presence of hard-wired circuitry that conveys visual information to the center that regulates feeding motivation in zebrafish. Find out more...

Fish cooperate for selfish reasons

Wed, 19 Apr 2017 09:16:01 EDT ~ Why do animals help raise offspring that aren't their own? A new study shows that fish cooperate to raise another fish's offspring to reduce their own risk of being eaten by a predator. Find out more...

Using tropical microbes to improve the environment

Tue, 18 Apr 2017 11:52:30 EDT ~ Researchers are harnessing properties in tropical microbes to address a variety of environmental, agricultural and aquacultural issues. Find out more...

Banning transshipment at-sea necessary to curb illegal fishing, researchers conclude

Tue, 18 Apr 2017 09:42:40 EDT ~ Banning transshipment at-sea -- the transfer of fish and supplies from one vessel to another in open waters -- is necessary to diminish illegal fishing, a team of researchers has concluded after an analysis of existing maritime regulations. Find out more...

Space bullethead parrotfish use is influenced more by competition than by fear of predators

Mon, 17 Apr 2017 15:50:25 EDT ~ Marine scientists find that the space bullethead parrotfish use is influenced more by competition than by fear of predators. Find out more...

New many-toothed clingfish discovered with help of digital scans

Mon, 17 Apr 2017 14:49:41 EDT ~ Scientists have discovered and named a new genus and species of clingfish after stumbling upon a specimen preserved in a jar dating back to the 1970s. High-resolution scans and 3-D printing helped the researchers make their discovery. Find out more...

Cave-in: How blind species evolve

Mon, 17 Apr 2017 08:59:54 EDT ~ Why do animals that live in caves become blind? Charles Darwin originally suggested that eyes could be lost by disuse over time. Now, an evolutionary biologist who wants to get to the heart of the matter may be proving Darwin wrong. Find out more...

Fish migration tracked by testing DNA in seawater

Wed, 12 Apr 2017 14:52:19 EDT ~ For the first time, researchers have successfully recorded fish migration by conducting DNA tests on seawater samples. Using this method to estimate the abundance and distribution of fish species could help scientists more easily understand the impact certain environmental factors are having on local fish populations. Find out more...

Distantly related fish find same evolutionary solution to dark water

Tue, 11 Apr 2017 15:10:29 EDT ~ Changes in a single color-vision gene demonstrate convergent evolutionary adaptations in widely separated species and across vastly different time scales, according to a new study. The study, which combined genetic analysis with a 19-year-long selection experiment, supports the idea that the mechanisms of adaptive evolution may be more predictable than previously suspected.
