Research measuring sea cucumber populations in WA's Scott Reef fishery has suggested an improved way of estimating exploitation rates.
(Phys.org) —A new study by University of Wisconsin-Madison Center for Limnology researchers says that when it comes to managing sport fisheries, regulations aren't in line with the reality of some fishing trips.
Parentage-based tagging (PBT) is an emerging genetic-based fish tagging method that involves genotyping hatchery broodstock. PBT is a passive non-invasive approach to stock identification because the parents, not the offspring, ...
Many factors—including climate change, overfishing or loss of food supply—can push a wild animal population to the brink of collapse. Ecologists have long sought ways to measure the risk of such a collapse, which could ...
A University of Leeds-led study, published in the journal Ecology Letters, overturns the common assumption that evolution only occurs gradually over hundreds or thousands of years.
Traditional community-run marine reserves and fisheries can play a big role in helping to restore and maintain fish numbers in stressed developing nations' coral reef fisheries.
Fishers near marine protected areas end up traveling farther to catch fish but maintain their social and economic well-being, according to a study by fisheries scientists at Washington State University and in Hawaii.
Previous studies have shown that carnivores can have indirect positive effects on each other, which means that when one species is lost, others could soon follow. A team from the University of Exeter and the University of ...
For most people, the sea is a deep, dark mystery. That is changing, though, as scientists find innovative ways to track the movements of ocean-going creatures.
As fish get smaller under Man's environmental impact, they become more exposed to predators, which means a crucial food source will become more endangered than thought, scientists said on Wednesday.
