Going diving in the tropics? Don't eat the reef fish!

Thu, 21 Sep 17 00:00:20 -0700

Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new UBC study that suggests other small island nations might also consider adopting this strategy.

Protected waters foster resurgence of West Coast rockfish

Wed, 20 Sep 17 00:13:30 -0700

West Coast rockfish species in deep collapse only 20 years ago have multiplied rapidly in large marine protected areas off Southern California, likely seeding surrounding waters with enough offspring to offer promise of renewed fishing, a new study has found.

Declining queen conch populations are fragmented and that's changing the conservation game

Tue, 19 Sep 17 00:10:30 -0700

To provide a vital scientific foundation for conservation efforts, an international team has conducted a genetic analysis comparing queen conch at 19 sites throughout the Caribbean. Their findings, published Sept. 19 in the journal Diversity and Distributions, will help scientists understand how local subpopulations of conch are fragmented throughout the Caribbean, an essential first step needed to develop effective science-driven management plans and practices.

Method to estimate abundance, trends in North Atlantic right whales confirms decline

Tue, 19 Sep 17 00:04:50 -0700

NOAA Fisheries researchers and colleagues at the New England Aquarium have developed a new model to improve estimates of abundance and population trends of endangered North Atlantic right whales, which have declined in numbers and productivity in recent years. Between 1990 and 2010 abundance increased to 482 animals, but since 2010 the numbers have declined to 458 in 2015, with 14 known deaths this year. The findings were published in the journal Ecology and Evolution.

Old fish few and far between under fishing pressure

Thu, 14 Sep 17 00:10:20 -0700

A new study by University of Washington scientists has found that, for dozens of fish populations around the globe, old fish are greatly depleted -- mainly because of fishing pressure. The paper, published online Sept. 14 in Current Biology, is the first to report that old fish are missing in many populations around the world.

An important process fueling harmful algal blooms investigated in Canadian water bodies

Wed, 13 Sep 17 00:15:00 -0700

Critical review examines the recycling of phosphorus from sediment to water and finds that internal phosphorus loading is common in Canadian fresh waters, but its importance is variable across the country.

Who is eating who? How climate change is modifying fish predator prey interactions

Fri, 08 Sep 17 00:07:50 -0700

Climate change is expected to have many impacts on the oceans; one of them is where fish are located in the ocean. Ocean warming is expected to cause fish to shift to different locations that are cooler -- generally toward the poles and into deeper waters. But not all fish are moving in the same directions and at the same speeds. This is changing what fish are eating and who are eating them.

18th century nautical charts document historic loss of coral reefs

Wed, 06 Sep 17 00:03:00 -0700

Researchers studying 18th century British nautical charts tracked the loss of coral reef habitat in the Florida Keys over the last two centuries. According to their analysis, entire sections of reef near the shore that were present prior to European settlement are now largely gone.

Korean researchers discover the biomechanism behind the formation of mother-of-pearl

Sun, 03 Sep 17 00:15:10 -0700

Professor Hyung Joon Cha and Dr. So Yeong Bahn at Pohang University of Science and Technology, in collaboration with Professor Yoo Seong Choi at Chungnam National University, have shed light on the key mechanism behind the formation of nacre. The team has discovered the role of the matrix protein Pif80 from the pearl oyster Pinctada fucata and its involvement in the development of the nacre.

Fish food for marine farms harbor antibiotic resistance genes
From isolated caves to ancient permafrost, antibiotic-resistant bacteria and genes for resistance have been showing up in unexpected places. As scientists puzzle over how genes for antibiotic resistance arise in various environments and what risks to human health they might pose, one team has identified a surprising way some of these genes are getting into ocean sediments: through food for marine fisheries. Their report appears in ACS' Environmental Science
