Hydrodynamic starvation: Why so many fish larvae perish after hatching

A new study has uncovered the reason why 90 percent of fish larvae are biologically doomed to die mere days after hatching. This understanding of the mechanism that kills off the majority of the world's fish larvae may help find a solution to the looming fish crisis in the world. The research suggests that "hydrodynamic starvation," or the physical inability to feed due to environmental incompatibility, is the reason so many fish larvae perish.

Dramatic decline of Caribbean corals can be reversed: Stop killing parrotfish to bring back Caribbean coral reefs

Dramatic decline of Caribbean corals can be reversed: Stop killing parrotfish to bring back Caribbean coral reefs | Aquaculture & Oceans | Scoop.it
With only about one-sixth of the original coral cover left, most Caribbean coral reefs may disappear in the next 20 years, primarily due to the loss of grazers in the region, according to a new report. The results show that the Caribbean corals have declined by more than 50% since the 1970s.

Coral trout pick their collaborators carefully

Coral trout pick their collaborators carefully | Aquaculture & Oceans | Scoop.it
Coral trout not only work with moray eels to improve their chances of a meal, but they can also be choosy when it comes to picking the best moray partner. The findings show that such sophisticated collaborative abilities are not limited to apes and humans. The fish's behavior is remarkable in other ways too, the researchers say.

Effect of ocean acidification: Coral growth rate on Great Barrier Reef plummets in 30-year comparison | Aquaculture & Oceans | Scoop.it
Researchers working in Australia's Great Barrier Reef have documented that coral growth rates have plummeted 40 percent since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown.

Nemo can travel great distances to connect populations: Baby clownfish travel hundreds of kilometers across open ocean

Nemo can travel great distances to connect populations: Baby clownfish travel hundreds of kilometers across open ocean | Aquaculture & Oceans | Scoop.it
Clownfish spend their entire lives nestling in the protective tentacles of host anemones, but new research shows that as babies they sometimes travel hundreds of kilometres across the open ocean. Although the process of long-distance dispersal by reef fish has been predicted, this is the first time that the high level exchange of offspring between distant populations has been observed.

Specialized species critical for reefs

Specialized species critical for reefs | Aquaculture & Oceans | Scoop.it
Coral reef ecologists fear that reef biodiversity may not provide the level of insurance for ecosystem survival that we once thought. This study found that even in high-diversity systems, such as tropical reefs, functional biodiversity remains highly vulnerable to species loss.

Judging a fish by its color: For female bluefin killifish, love is a yellow mate

Researchers used male replicas of bluefin killifish and controlled their movement with robotic arms to improve repeatability in experiments designed to determine how fertile female fish would respond to male courtship. The surprising result: The females preferred males with yellow fins, contrary to existing research that indicated a preference to blue and red.

Climate change could stop fish finding their friends

Climate change could stop fish finding their friends | Aquaculture & Oceans | Scoop.it
Like humans, fish prefer to group with individuals with whom they are familiar, rather than strangers. This gives numerous benefits including higher growth and survival rates, greater defense against predators and faster social learning. However, high carbon dioxide levels, such as those anticipated by climate change models, may hinder the ability of fish to recognize one another and form groups with familiar individuals.

It is popularly believed that fish have a memory span of only 30 seconds. Canadian scientists, however, have demonstrated that this is far from true -- in fact, fish can remember context and associations up to 12 days later.

Shift in Arabia sea plankton may threaten fisheries | Aquaculture & Oceans | Scoop.it
The rapid rise of an unusual plankton in the Arabian Sea has been documented by researchers who say that it could be disastrous for the predator fish that sustain 120 million people living on the sea's edge. "These blooms are massive, appear year after year, and could be devastating to the Arabian Sea ecosystem over the long-term," said the study's lead author.

The warm Atlantic water continued to flow into the icy Nordic seas during the coldest periods of the last Ice Age. An ice age may sound as a stable period of cold weather, but the name deceives. In the high latitudes of the Northern Hemisphere, the period was characterized by significant climate changes. Cold periods (stadials) switched abruptly to warmer periods (interstadials) and back.
