How sustainable is tuna? New global catch database exposes dangerous fishing trends
Scientists have found that global tuna catches have increased over 1,000 per cent in the past six decades, fueled by a massive expansion of industrial fisheries.
Read morePredators and hidey-holes are good for reef fish populations
New research highlights two factors that play a critical role in supporting reef fish populations and – ultimately – creating conditions that are more favorable for the growth of both coral reefs and seagrass.
Read moreThe hidden ark: How a grassroots initiative can help save fish from extinction
Freshwater fish are the most threatened vertebrate group, and species are disappearing faster than scientists can describe them. A new study shows that aquarium hobbyists can play an important role in freshwater fish conservation by filling in the gaps left by the scientific community and conservation organizations.
Read moreGerman fishermen's skepticism towards EU impedes compliance with its regulations
Negative perception of a regulatory authority diminishes the honesty of those regulated. This is the conclusion of an experiment with EU-skeptic commercial fishermen and Brexit voters. The findings can help to assess the effectiveness of unmonitored EU fisheries regulations.

Negative perception of a regulatory authority diminishes the honesty of those regulated. This is the conclusion of an experiment with EU-sceptic commercial fishermen and Brexit voters. The findings can help to assess the effectiveness of unmonitored EU fisheries regulations. The experiment also revealed: Fishermen were more honest than students.

Rising ocean temperatures have long been linked to negative impacts for marine life, but a team has recently found that the long-term outlook for many marine species is much more complex — and possibly bleaker — than scientists previously believed.
Read moreFish fathers exhibit signatures of 'baby brain' that may facilitate parental care behavior
Many new parents are familiar with terms like 'baby brain' or 'mommy brain' that hint at an unavoidable decline in cognitive function associated with the hormonal changes of pregnancy, childbirth, and maternal caregiving. A new study of parental care in stickleback fish is a reminder that such parenting-induced changes in the brain and associated shifts in cognition and behavior are not just for females — and they're not just for mammals either.

A new analysis of Kotzebue Sound fish has found that mercury levels in a variety of its subsistence species are safe for unrestricted consumption. The study tested 297 subsistence-caught fish. The average mercury levels for each of the eight species were at levels considered safe by the Alaska Department of Health and Social Services.
